pandoc-2.18-150500.1.2 RPM for s390x

From OpenSuSE Leap 15.6 for s390x

Pandoc is a Haskell library for converting from one markup format to another,
and a command-line tool that uses this library. The formats it can handle
include

- light markup formats (many variants of Markdown, reStructuredText, AsciiDoc,
Org-mode, Muse, Textile, txt2tags) - HTML formats (HTML 4 and 5) - Ebook
formats (EPUB v2 and v3, FB2) - Documentation formats (GNU TexInfo, Haddock) -
Roff formats (man, ms) - TeX formats (LaTeX, ConTeXt) - XML formats (DocBook 4
and 5, JATS, TEI Simple, OpenDocument) - Outline formats (OPML) - Bibliography
formats (BibTeX, BibLaTeX, CSL JSON, CSL YAML) - Word processor formats (Docx,
RTF, ODT) - Interactive notebook formats (Jupyter notebook ipynb) - Page layout
formats (InDesign ICML) - Wiki markup formats (MediaWiki, DokuWiki, TikiWiki,
TWiki, Vimwiki, XWiki, ZimWiki, Jira wiki, Creole) - Slide show formats (LaTeX
Beamer, PowerPoint, Slidy, reveal.js, Slideous, S5, DZSlides) - Data formats
(CSV tables) - PDF (via external programs such as pdflatex or wkhtmltopdf)

Pandoc can convert mathematical content in documents between TeX, MathML, Word
equations, roff eqn, and plain text. It includes a powerful system for
automatic citations and bibliographies, and it can be customized extensively
using templates, filters, and custom readers and writers written in Lua.

Changelog

* Mon Apr 04 2022 [email protected]
  - Update pandoc to version 2.18.
    [#]# pandoc 2.18 (2022-04-22)
    * New input formats: `endnotexml` (EndNote XML bibliography),
      `ris` (RIS bibliography).
    * A RIS bibliography file may now be used with `--citeproc`.
    * Citeproc: Allow a formatted bibliography to be placed in metadata fields
      via a Div with class `refs` (#7969, #526).  Thus, one can include a
      metadata field, say `refs`, whose content is an
      empty div with id `refs`, and the formatted bibliography will be put into
      this metadata field.  It may then be interpolated into a template using the
      variable `refs`.
    * Ensure that you don't get PDF output to terminal.  `-t pdf` now behaves
      like `-t docx` and gives an error unless the output is redirected.
    * `--version` now prints hslua version (#7929) and
      Lua version (#7997, Albert Krewinkel).
    * Change `--metadata-file` parsing so that, when the input format is not
      markdown or a markdown variant, pandoc's markdown is used (#6832, #7926).
      When the input format is a markdown variant, the same format is used.
      Reason for the change: it doesn't make sense to run the markdown parser
      with a set of extensions designed for a non-markdown format, and
      this dramatically limits what people can do in metadata files.
    * Trim whitespace from math in `--webtex` (#7892).
      This fixes problems with --webtex and markdown output,
      when display math starts or ends with a newline.
    * New exported module Text.Pandoc.Readers.EndNote, exporting
      `readEndNoteXML`, `readEndNoteXMLCitation`,
      and `readEndNoteXMLReferences`. [API change]
    * `--self-contained`: issue warning rather than failing with an error
      if a resource can't be found (#7904).
    * New exported module, Text.Pandoc.Readers.RIS, exporting `readRIS` (#7894).
    * LaTeX reader:
      + Handle subequations as inline math environment (#7883).
      + Rudimentary support for `vbox` (#7939).
      + Support `\today` (#7905).
      + Handle `\label` and `\ref` for footnotes (#7930).
      + Allow inline groups starting with `\bgroup` (#7953).
      + Use custom TokStream that keeps track of whether macros are expanded.
      This allows us to improve performance a bit by avoiding unnecessary
      runs of the macro expansion code (e.g. from 24 ms to 20 ms on
      our standard benchmark).
      + Further optimizations for inline parsing.
      + Better handling of `\usepackage`.  If the package is local but
      causes parse errors, parse everything up to the error and skip the
      rest.  Issue a `CouldNotParseIncludeFile` warning indicating that
      parsing failed at that point.
      + Text.Pandoc.Readers.LaTeX.Parsing: Monoid and Semigroup instances for
      TokStream.
    * HTML reader:
      + Give warnings and emit empty note when parsing
      `<a epub:type="noteref">` and the identifier
      doesn't correspond to anything in the note table (#7884).
      Previously we just silently skipped these cases.
      + Fix parsing of epub footnotes (#7884).
    * DocBook reader:
      + Handle complete set of entities as specified at
      <https://www.w3.org/2003/entities/2007doc/byalpha.html> (#7938).
      + Handle abstract in info section (#7747).
      + Improve info parsing.
      + Simplify metadata parsing code (#7747).
      Handle abstract as block-level content.
      Report skipped info elements with `--verbose`.
      + Handle address and coyright in metadata (#7747).
    * DokuWiki reader:
      + Add DokuWiki table alignment (#5202, damon-sava-stanley).
    * RST reader:
      + Fix treatment of headerless simple tables (#7902).
      + Wrap math in Span to preserve attributes (#7998, Albert Krewinkel).
      Math elements with a name, classes, or other fields are wrapped in a
      `Span` with these attributes.
    * JATS reader:
      + Improve handling of fn-group elements (#6348, Albert Krewinkel).
      Footnotes in `<fn-group>` elements are collected and re-inserted into
      the document as proper footnotes in the place where they are referenced.
      + Handle `pub-date` (#8000).
      + Support PMID, DOI, issue in citations (#7995).
      + Improve refs parsing.  Handle `issn` and `isbn`; use simpler form
      for issued date.
      + Strip 'ref-' from ref id in constructing CSL id.  This allows better
      round-tripping, because the JATS writer adds the `ref-` prefix to
      the citation id to get the ref element's id.
    * Org reader:
      + Allow ":" in property drawer keys (Lucas V. R).
      Any non-space character is allowed as property drawer key, including ":"
      itself (so it is not really a delimiter). The real delimiter is a space
      character, so in a drawer like
      ```
      :PROPERTIES:
      ::k:ey:: value
      :END:
      ```
      ":k:ey:" is a key with value "value".
      + Allow comments above property drawer.
      + More flexible LaTeX environments (Lucas V. R).
      + Handle `#+bibliography:` as metadata so that it can work with
      `--citeproc`.
      + Parse `#+print_bibliography:` as Div with id `refs`.
      + Allow multiple `#+bibliography:`.
    * Markdown reader:
      + Allow one-column pipe tables with pipe on right (#7919).
      + Remove restriction on identifiers, so they no longer need to
      begin with a letter (#7920).
    * Docx reader:
      + Enable `citations` extension for docx reader (#7840).
      When enabled, Zotero, Mendeley, and EndNote citations embedded in
      a docx are parsed as native pandoc citations.
      (When disabled, the generated citation
      text and bibliography are passed through as regular text.)
      The bibliography generated by the plugin is suppressed.
      Instead, bibliographic data embedded in citation items is added
      to the `references` metadata field so that it can be used
      with `--citeproc`.
    * Docbook writer:
      + Interpret links without contents as cross-references (#7360, Jan Tojnar).
      Links without text contents are converted to `<xref>` elements. DocBook
      processors will generate appropriate cross-reference text when presented
      with an xref element.
    * Docx writer:
      + Single numbering ID for examples (#7895, mjfs).
      This change ensures that example list items all belong to a single
      number sequence, so that if items are added or deleted in a word
      processor, the other items will renumber automatically.
      + Add bookmark with table id to table (#7989, Nikolai
      Korobeinikov, #7285).  This allows tables with ids to be linked to.
    * Ipynb writer:
      + Handle metadata better (#7928).  Previously we used the markdown
      writer to render metadata.  This had some undesirable consequences
      (e.g. en dash expanded to `--` when `smart` enabled), so now we use
      the plain writer.
    * LaTeX writer:
      + Avoid extra space before `\CSLRightInline` (#7932).
      + Add `scrreport` to `chaptersClasses` (#6168, ivardb).
      + Support `page`,`trim`,`clip` attributes on images (#7181).
      + Add `()` after booktabs rules (#8001).  These commands take optional
      arguments with () and [], which can lead to problems if the content
      of the table cell begins with these characters.
    * RST writer:
      + Support all standard metadata ("bibliographic") fields.
    * HTML writer: performance improvements.
    * Org writer:
      + Stop indenting property drawers, quote blocks
      (#3245, Albert Krewinkel).  This follows the current default org-mode
      behavior.
    * Markdown writer:
      + Move table-related code into submodule (Albert Krewinkel).
      + Don't produce redundant header identifier when the
      `gfm_auto_identifiers` extension is set (#7941).
      + Update escaping rules for `\`.  We now escape `\` only if `raw_tex`
      is enabled or it is followed by a non-alphanumeric.
    * JATS writer:
      + Encode author "others" as `<etal/>` (Albert Krewinkel).
      Citeproc adopted the BibTeX convention to use the author name "others"
      when there are additional authors that are not named. JATS uses the
      `<etal>` element for this.
      + Avoid doubled ref-list element (#7990).  Previously when generating JATS
      with the `element_citations` extension enabled, the references were
      put in a doubly-nested ref-list element (`<ref-list><ref-list>...`).
      + Keep edition info in element citations (#7993, Albert Krewinkel).
      + Fix handling of CSL variable 'page' (not 'pages' as we had before).
      It should go to 'lpage' and 'rpage', not 'page-range'.
    * EPUB writer: refactor for clarity (#7991, Jonathan Dönszelmann,
      Ola Wolska, Ivar de Bruin, Jaap de Jong).
    * Custom writer (Albert Krewinkel):
      + Support new-style Writer function (Albert Krewinkel).
      See the documentation for custom writers for details.
      + Produce stacktrace if Writer function fails
    * Text.Pandoc.Logging: add `CouldNotParseIncludeFile` constructor
      for `LogMessage` [API change].
    * Text.Pandoc.Shared:
      + Put id attributes on TOC entries (#7907, damon-sava-stanley).
      Naming scheme of id is "toc-" + id of linked to header/section.
      Effects HTML, Markdown, Powerpoint, and RTF.
      + Define `ordNub` as alias for `nubOrd` from containers package (#7963,
      Albert Krewinkel).
      + Export `ensureValidXmlIdentifiers`.  This function changes identifiers
      that don't start with letters, and internal links to these identifiers,
      making them compatible with XML standards.  The change
      is simple: we add `id_` to the front.  There is potential
      for duplication if there are already `id_...` identifiers
      defined, but this seems rare enough not to worry too much
      about.
    * Ensure that valid XML identifiers are used in Docbook, EPUB, FB2,
      HTML4, S5, Slidy, Slideous, ICML, ODT, TEI writers.
      Thus, if you convert `[anchor]{#1} and [link to](#1)`,
      `id_1` will be used instead of `1` for the identifier.
    * Lua (Albert Krewinkel).
      + Add module `pandoc.layout` to format and layout text.
      + Move custom writer code into Lua hierarchy.
      + Use pandoc-lua-marshal 0.1.5.
      +  Allow any type of callable object as argument to List
      functions `filter`, `map`, and `find_if`. These previously
      required the argument to be of type `function`, which was too
      restrictive.
      + Inline: the type of Image captions is now `Inlines` instead of `List`.
      + Allow passing `Sources` to `pandoc.read` (#8002).
    * Text.Pandoc.PDF:
      + Restore `wkhtmltopdf` as default pdf engine for HTML (Albert Krewinkel).
      + Allow custom writer as format if engine is explicitly specified (#7898,
      Albert Krewinkel).  Note that it may be necessary to explicitly
      specify a template on the command line.
    * Text.Pandoc.MediaBag: improve detection of absolute paths (#7881).
    * Text.Pandoc.Extensions:
      + Remove `raw_tex` extension from list of commonmark extensions, and
      from the `commonmark_x` defaults.  commonmark doesn't parse raw TeX,
      and it doesn't make sense to write it if we don't parse it.
      + Remove `native_divs` from allowed gfm extensions (#7965).  This allows
      `<div>` to be suppressed using `-raw_html`.  Previously `native_divs`
      was enabled but could not be suppressed, because it was not in the
      list of available extensions for commonmark-based formats.
    * Text.Pandoc.Parsing:
      + Partition module into (internal) submodules (#7962, Albert Krewinkel).
      + Unify grid table parsing (#7971, Albert Krewinkel).
      Grid table parsing in Markdown and RST are updated use the same
      functions. Functions are generalized to meet requirements for both
      formats.  This change also lays the ground for further generalizations
      in table parsers, including support for advanced table features.
      [API change] in Text.Pandoc.Parsing:
    - Parse results of functions `tableWith'` and `gridTableWith'` are now a
      `mf TableComponents` instead of a quadruple of alignments, column
      widths, header rows and body rows.
    - Additional exports from Text.Pandoc.Parsing:
      `tableWith'`, `TableComponents`, `TableNormalization`,
      `toTableComponents`, `toTableComponents'`.
    * Text.Pandoc.XML.Light: add versions of the parsers that allow
      specifying a custom entity map.  Exports new functions:
      `parseXMLElementWithEntities`, `parseXMLContentsWithEntities` [API change].
    * Text.Pandoc.Writers.GridTable: improve module documentation (Albert
      Krewinkel).
    * Text.Pandoc.Parsing.GridTable: simplify column handling code (Albert
      Krewinkel).
    * Text.Pandoc.MIME: Add mime type for mkv extension (#7181).
    * Text.Pandoc.Asciify: Fix regression with `ascii_identifiers` and Turkish
      undotted i (#8003).
    * Relax upper bound for hslua, allow hslua-2.2. (#7929)
      Lua 5.4 is used by default after this is merged. Packagers may still
      include Lua 5.3 instead by building pandoc with `--constraint='hslua <2.2'`.
      Differences between 5.3 and 5.4 should not generally affect pandoc Lua
      filters.  See list of incompatible changes here:
      <https://www.lua.org/manual/5.4/manual.html#8.1>
    * JATS template: allow multiple licenses (Albert Krewinkel).
    * LaTeX template:
      + Skip `\babelprovide` if `babel-lang` is empty (#7945) to avoid an error.
      + Move hyperref near end of preamble (#5811).  It now comes after
      header-includes and right before title, author, date, abstract.
      Note:  Users who presuppose hyperref in their header-includes
      will now have to add `\usepackage{hyperref}` to their header-includes
      to make it available there.  (The redundant `\usepackage` will
      do no harm in this case.)
      + Remove special redefinition of `\sout`.  This used to be necessary to
      avoid problems with hyperref, when headings contain strikeout text,
      but it does not seem to be necessary any more (tested).
    * Tests: improve location reporting of failing tests (Albert Krewinkel).
    * Add tests for idempotency of `makeSections` (#7950).
    * Add armhf support in linux build script (#7944, Tony).
    * Use latest pandoc-types, so that toJSONFilter will work with
      Meta and MetaValue.
    * Use latest doclayout, texmath, commonmark, citeproc.
    * INSTALL.md: add reference to install via winget (#7951, Guriy Samarin).
    * MANUAL.txt:
    - Document way to get list in block quote in slide shows (#7916).
    - Minor changes to security section.
    - Note that `smart` works for html input.
    - Fix typos (#7934, Dimitris Apostolou).
    - Fix documentation for citations and org mode.
    - Remove claim that `--self-contained` does not work with `--mathjax`
      (#682).
    * doc/org.md: remove obsolete citations section.
      This mostly described citation formats we no longer support.
    * doc/lua-filters.md: Fix typo (#7981, Mario Lang).
    * Makefile: Use cabal for default build
    * Add `lua53` cabal flag.  It is false by default.  If set to true, compile
      with hslua 2.1 and Lua 5.3, otherwise hslua 2.2 and Lua 5.4.
* Mon Jan 31 2022 [email protected]
  - Update pandoc to version 2.17.1.1.
    [#]# pandoc 2.17.1.1 (2022-01-31)
    * Fix regression in 2.17.1 which caused problems finding
      default files in the default user data directory.  (Reverts
      the item "logic bug in `fullDefaultsPath`", which was
      misguided.)
    * Sample custom writer: use single quotes for strings (#7487,
      Albert Krewinkel).
    [#]# pandoc 2.17.1 (2022-01-30)
    * Support `pagedjs-cli` as pdf engine (#7838, Albert Krewinkel).
      PagedJS is a polyfill and supports the Paged Media standards by the W3C.
      <https://www.pagedjs.org/>
    * CommonMark reader: fix source position after YAML metadata (#7863).
    * LaTeX reader:
      + Remove retokenizing in `rawLaTeXParser`.
      + Ensure that `\raggedright` doesn't gobble an argument (#7757).
      + Improve `descItem`.  For some reason we were skipping
      arbitrary blocks before `\item`.  This is now changed to "skip
      whitespace and comments."
      + Improve handling of `\newif`.  Adding a pair of braces around the
      second argument of `\def` prevents LaTeX from an emergency stop
      on input like the following (#6096).
      ```
      \newif\ifepub
      \epubtrue
      \ifepub
      hi
      \fi
      ```
    * Docx reader: Parse both Zotero citation and bibliography as
      `FieldInfo` (#7840).
    * LaTeX writer:
      + Allow arbitrary frameoptions to be passed to a beamer
      frame, using the frameoptions attribute (#7869).
      + Add s and squeeze to recognized beamer frameoptions (#7869).
    * Markdown writer: handle explicit column widths with pipe tables (#7847).
      If a table has explicit column width information *and* the content
      extends beyond the `--columns` width, we need to adjust the
      widths of the pipe separators to encode this width information.
    * Docx writer: Separate tables even with RawBlocks between (#7224,
      Michael Hoffmann).  Adjacent docx tables need to be separated by an
      empty paragraph. If there's a RawBlock between tables which renders
      to nothing, be sure to still insert the empty paragraph so that
      they will not collapse together.
    * Man writer: use custom font V for inline code (#7506).
      The V font is defined conditionally, so that it renders
      like CB in output formats that support that, and like B
      in those that don't (e.g. the terminal).
      Aliases also defined for VI, VB, VBI.
    * Asciidoc writer: Support checklists in asciidoctor writer (#7832,
      Nikolai Korobeinikov, ricnorr).  The checklist syntax (similar to
      `task_list` in markdown) seems to be an asciidoctor-only addition.
    * HTML writer:
      + Avoid duplicate "style" attributes on table cells (#7871).
      + Don't break lines inside code elements.  With the new (default)
      line wrapping of HTML, in conjunction with the default CSS which
      includes `code { whitespace: pre-wrap; }`, spurious line
      breaks could be introduced into inline code (#7858).
    * Custom writer: preserve order of element attributes (#7489, Albert
      Krewinkel).  Attribute key-value pairs are marshaled as AttributeList,
      i.e., as a userdata type that behaves both like a list and a map. This
      allows to preserve the order of key-value pairs.
    * Switch to hslua-2.1 (Albert Krewinkel). This allows for some code
      simplification and improves stability.
    * Don't read files outside of user data directory (Even Brenden).
      If a file path does not exist relative to the working directory, and
      it does exist relative to the user data directory, but outside of
      of the user data directory, do not read it. This applies to
      `readDataFile` and `readMetadataFile` in PandocMonad and, by
      extension, any module that uses these by passing them relative paths.
    * Text.Pandoc.Class.`makeCanonical`: Correctly handle consecutive ".."s
      at the beginning of a path (Even Brenden).  Prior to this commit,
      `../../file` would evaluate to `file`, when it should be unchanged.
    * Search for metadata files in `$DATADIR/metadata` (#7851, Even Brenden).
      If files specified with `--metadata-file` are not found in the working
      directory, look in `$DATADIR/metadata` (#5876).
    * Text.Pandoc.Class: export `readMetadataFile` [API change] (#5876).
    * Text.Pandoc.Error: export new `PandocCouldNotFindMetadataFileError`
      constructor for `PandocError` [API change] (#5876).
    * Avoid putting a frame around speaker notes in beamer (#7857).
      If speaker notes (a Div with class 'notes') occur right
      after a section heading, but above slide level, the
      resulting `\note{..}` caommand should not be wrapped in
      a frame, as that will cause a spurious blank slide.
    * CSS in HTML template: adjust #TOC and h1 on mobile (#7835, Mauro Bieg).
    * Text.Pandoc.Readers.LaTeX.Parsing: don't export `totoks`.
      Make the first param of `tokenize` a SourcePos instead of
      SourceName, and use it instead of `totoks`.
    * Text.Pandoc.Shared: Modify `stringify` so it ignores `[Citation]`
      inside `Cite` (#7855).  Otherwise we'll sometimes get two copies of
      things, one from the `citationPrefix` or `citationSuffix` and another
      from the embedded fallback text.  When there is no fallback text,
      we'll get no content.  However, it really isn't an alternative to just
      rely on the result of running `query` on the embedded `Citation`s;
      this will result in a jumble of text rather than anything structured.
    * Omit `--enable-doc` in the cabal haddock invocation in
      `tools/build-and-upload-api-docs.sh`.
    * Text.Pandoc.App.Opt: fix logic bug in `fullDefaultsPath`.
      Previously we would (also) search the default user data directory
      for a defaults file, even if a different user data directory
      was specified using `--data-dir`.  This was a mistake; if
      `--data-dir` is used, the default user data directory should
      not be searched.
    * Text.Pandoc.Shared: `defaultUserDataDir` behavior change (#7842).
      If the XDG data directory is not defined (e.g. because
      it's not supported in the OS or HOME isn't defined), we
      return the empty string instead of raising an exception.
    * Update command tests to distinguish stderr and test exit status.
    * MANUAL: add that speaker notes can be used with beamer (#7856).
    * Update `build-and-upload-api-docs.sh`.
    * Document `--trace` option.
      Document `no-check-certificate` in defaults files.
      Document 'sandbox' option for defaults files.  (#7873).
    * Fix pattern syntax in sample readability custom reader.
    * doc/custom-readers.lua: add example for "readable HTML."
    * Fix message in man page about where code can be found.
    * `manfilter.lua`:  remove extra indent in table cells with code blocks.
    * Fix lua-filters documentation for table column widths (#7864).
    * epub.doc: Update links to KindleGen (#7846, Benson Muite, Mauro Bieg).
      KindleGen has been deprecated and we need to link to archived versions.
    * Use tables in defaults files documentation, so each
      default option is paired with the corresponding command-line
      option (Carsten Allefeld).
    * Use skylighting 0.12.2.
    * Add pandoc-lua-marshal to Nix shell (#7849, Even Brenden).
    [#]# pandoc 2.17.0.1 (2022-01-14)
    * Require pandoc-lua-marshal 0.1.3.1 (#7831, Albert Krewinkel).
      Fixes a problem with `List.includes` and `List.find` that caused a
      Lua stackoverflow and subsequent program crash.
    * HTML template: load header-includes before math (#7833, Kolen Cheung).
      MathJax expect the config comes before loading the MathJax script.
      This change of order allows one to config MathJax via
      header-includes, which loads before the MathJax script. Cf. #2750.
    * When reading defaults file, stop at a line `...`.  This line signals
      the end of a YAML document.  This restores the behavior we got with
      HsYaml.  yaml complains about content past this line.  See
      https://github.com/jgm/pandoc/issues/4627#issuecomment-1012438765
    * Text.Pandoc.Citeproc: allow `notes-after-punctuation` to work with
      numerical styles that use superscripts (e.g.
      american-medical-association.csl), as well as with note styles. The
      default setting of `notes-after-punctuation` is true for note styles
      and false otherwise.  This restores a behavior of pandoc-citeproc
      that wasn't properly carried over to Citeproc (#7826, cf.
      jgm/pandoc-citeproc#384).
    * Use commonmark-pandoc 0.2.1.2 (#7769).
    * Add FAQ on images in ipynb containers (#7749, Kolen Cheung).
    [#]# pandoc 2.17 (2022-01-12)
    * Support `markua` as an output format (#1871, Tim Wisotzki and
      Saumel Lemmenmeier). Markua is a markdown variant used by Leanpub.
    * Add text wrapping for HTML output (#7764). Previously the HTML writer
      was exceptional in not being sensitive to the `--wrap` option.  With
      this change `--wrap` now works for HTML. The default (as with other
      formats) is automatic wrapping.  Note that the contents of `script`,
      `textarea`, and `pre` tags are always laid out with the `flush`
      combinator, so that unwanted spaces won't be introduced if these occur
      in an indented context in a template.
    * Don't read sources until in/out format are verified (#7797).
    * Issue error with `--list-extensions` for invalid formats (#7797).
    * Make `--citeproc` recognize `.yml` as well as `.yaml` extensions
      as YAML bibliography files (#7707, Jörn Krenzer).
    * Use latest version of KaTeX with `--katex`.
    * Fix parsing of footnotes in `--metadata-file` (#7813).  Previously
      non-inline footnotes were not being parsed.
    * ODT reader:
      + Parse list-header as a list item (Tuong Nguyen Manh).
    * Commonmark reader:
      + Put sourcepos attribute on header, not enclosing div
      with `-f commonmark+sourcepos` (#7769).
    * Markdown reader:
      + Don't allow `^` at beginning of link or image label (#7723).
      This is reserved for footnotes. Fixes regression from 0a93acf.
      + Fix parsing of "bare locators" after author-in-text citations.
      Previously `@item [p. 12; @item2]` was incorrectly parsed as
      three citations rather than two.  This is now fixed by ensuring
      that `prefix` doesn't gobble any semicolons.
      + Revert changes to `inlinesInBalancedBrackets` (commit fa83246),
      which caused regressions.
      + Improve detection of pipe table line widths (#7713).  Fixed
      calculation of maximum column widths in pipe tables.  It is
      now based on the length of the markdown line, rather than a
      "stringified" version of the parsed line.  This should be
      more predictable for users. In addition, we take into account
      double-wide characters such as emojis.
    * Custom (Lua) readers:
      + First argument is now a list of sources instead of the
      concatenated text (Albert Krewinkel).  The list
      structure can easily be converted to a string by applying
      `tostring`, but it is also possible to access the elements
      (each with a `text` and `name`). A small example is added
      to the custom reader documentation, showcasing its use in a
      reader that creates a syntax-highlighted code block for
      each source code file passed as input. Existing readers
      will still work through a fallback mechanism, issuing a
      deprecation notice.
    * Org reader:
      + Parse official org-cite citations (#7329). We also support the older
      org-ref style as a fallback. We no longer support the
      "markdown style" or "Berkeley style" citations.
      + Support alphabetical (fancy) lists (Lucas Viana). When the
      `fancy_lists` extension is enabled, alphabetical list markers are
      allowed, mimicking the behaviour of Org Mode when
      `org-list-allow-alphabetical` is enabled.
      + Support counter cookies in lists (Lucas Viana). Such cookies are
      used to override the item counter in ordered lists. In org it is
      possible to set the counter at any list item, but since Pandoc AST
      does not support this, we restrict the usage to setting an offset for
      the entire ordered list, by using the cookie in the first list item.
      + Allow trailing spaces after key/value pairs in directives (Albert
      Krewinkel). Ensures that spaces at the end of attribute directives like
      `#+ATTR_HTML: :width 100%` (note the trailing spaces) are accepted.
    * LaTeX reader:
      + Omit visible content for `\label{...}`. Previously we
      included the text of the label in square brackets, but this is
      undesirable in many cases. See discussion in
      <https://github.com/jgm/pandoc/issues/813#issuecomment-978232426>.
      + Improve references (#813). Resolve references to theorem environments.
      Remove the Span caused by "label" in figure, table, and theorem
      environments; this had an id that duplicated the environments' id.
      + Fix semantics of `\ref`. We were including the ams
      environment type in addition to the number. This is proper
      behavior for `\cref` but not for `\ref`.  To support `\cref`
      we need to store the environment label separately.
      + Add babel mappings for Guajati (gu) and Oriya (or) (#7815).
      + Fix typo `panjabi` -> `punjabi` in babel mappings (#7814).
    * HTML reader:
      + Parse attributes on links and images (#6970).
    * Docx reader:
      + Handle multiple pic elements inside a drawing (#7786).
      + Change `elemToParPart` to return `[ParPart]` instead of `ParPart`.
      Also remove `NullParPart `constructor, as it is no longer
      needed. This will allow us to handle elements that contain
      multiple ParParts, e.g. `w:drawing` elements with multiple `pic:pic`.
    * DocBook reader:
      + Collapse internal spaces in literal and other similar tags (#7821),
      as the standard docbook toolchain does.
      + Be sensitive to spacing="compact" in lists (#7799). When
      `spacing="compact"` is set, Para elements are turned into Plain,
      so we get a "tight" list.
    * Markdown writer:
      + Add new exported function `writeMarkua` from Text.Pandoc.Writers.Markdown
      [API change] (#1871, Tim Wisotzki and Saumel Lemmenmeier).
      + Fix indentation issue in footnotes (#7801).
      + Avoid extra space before citation suffix if it already starts
      with a space.
      + Ensure semicolon between the locator and the next citation when an
      author-in-text citation has a locator and following citations.
      + Improve escaping for `#` (#7726).
    * Custom (Lua) writers:
      + Allow variables to be set via second return value of `Doc`
      (#6731, Albert Krewinkel). New templates variables can be added by
      giving variable-value pairs as a second return value of the
      global function `Doc`. Example:
      ```
      function Doc (body, meta, vars)
      vars.date = vars.date or os.date '%B %e, %Y'
      return body, vars
      end
      ```
      + Provide global `PANDOC_WRITER_OPTIONS` (#6731, Albert Krewinkel).
      + Assign default Pandoc object to global `PANDOC_DOCUMENT` (Albert
      Krewinkel). The default Pandoc object is now non-strict, i.e., only
      the parts of the document that are accessed will be marshaled to Lua.
      A special type is no longer necessary. This change also makes it
      possible to use the global variable with library functions such as
      `pandoc.utils.references`, or to inspect the document contents with
      `walk()`.
    * LaTeX writer:
      + Fix typo `panjabi` -> `punjabi` in babel mappings (#7814).
    * MediaWiki writer:
      + Remove redundant display text for wiki links (Jesse Hathaway).
    * Docx writer:
      + Handle bullets correctly in lists by not reusing numIds
      (#7689, Michael Hoffmann).  This fixes a bug in which a Div in
      a list item would receive bullets on its contained paragraphs.
    * Org writer:
      + Fix list items starting with a code block or other non-paragraph
      content (#7810).
      + Avoid blank lines after tight sublists (#7810).
      + Fix extra blank line inserted after empty list item (#7810).
      + Don't add blank line before lists (#7810).
      + Support starting number cookies (Lucas Viana).  This is necessary
      for lists that start at a number other than 1.
      + Support the new org-cite syntax (#7329).
    * Haddock writer:
      + Avoid blank lines after tight sublists (#7810).
    * Ipynb writer:
      + Ensure deterministic order of keys.
      + Handle cell output with raw block of markdown (#7563, Kolen Cheung).
      Write RawBlock of markdown in code-cell output. This is designed
      to fit the behavior of #7561, which makes the ipynb reader parse
      code-cell output with mime "text/markdown" to a RawBlock of markdown.
      This commit makes the ipynb writer writes this RawBlock of markdown
      back inside a code-cell output with the same mime, preserving this
      information in round-trip.
      + In choosing between multiple output options, always favor
      those marked with the output format over images (Kolen Cheung).
      Previously, both `fmt == f` case and Image have a rank of 1.
    * Ipynb reader & writer: properly handle cell "id" (#7728).
      This is passed through if it exists (in Nb4); otherwise
      the writer will add a random one so that all cells have an "id".
    * Ms writer:
      + Properly encode strings for PDF contents (#7731).
    * JATS writer:
      + Keep quotes in element-citations (Albert Krewinkel).
      Fixed a bug that lead to quote characters being lost in
      element-citations.
    * RTF writer:
      + Properly handle images in data URIs (#7771).
    * Commonmark writer:
      + Allow ')' delimiters on ordered lists.
    * RST writer:
      + Avoid extra blank line after empty list item (#7810).
    * HTML writer:
      + Make line breaks more consistent. With `--wrap=none`, we now
      output line breaks between block-level elements. Previously they
      were omitted entirely, so the whole document was on one line, unless
      there were literal line breaks in pre sections.  This makes
      the HTML writer's behavior more consistent with that of
      other writers. Also, regardless of wrap settings,
      put newline after `<dd>` and after block-level elements in
      the footnotes section. And add a line break between an `img` tag
      and the associated `figcaption`.
      + reveal.js: Make sure images with `r-stretch` are not in p tags.
      They must be direct children of the section. There was previously
      code to make this work with the older class name `stretch`, but
      the name has changed in reveal.js.
      + reveal.js:  don't add `r-fit-text` class to section. It must go on
      the header only.
    * AsciiDoc writer:
      + Improve detection of intraword emphasis (#7803).
    * OpenDocument writer:
      + Fix vertical alignment bug with display math (#7777).  Previously some
      displayed formulas would be floated above a preceding text line.
      This is fixed by setting `vertical-rel` to `text` rather than
      `paragraph-content`.
    * JATS template (Albert Krewinkel):
      + Fix position of contrib affiliations in authoring set. Any
      `<aff>` element must come before any `<email>` element.
      + Fix affiliation tagging in `articleauthoring` output.
      Affiliations were `xlink`ed even in the articleauthoring tag set, but
      `<aff>` are not allowed as children of `contrib-group` elements in that
      tag set. Each affiliation must be listed directly in the contrib
      element.
      + Add support for article subtitles.
    * EPUB template:
      + Include abstract in default template.
      + Ensure that the essential styles needed by pandoc (`styles.html`
      partial) are included in the templates. This is important for correct
      formatting of CSL bibliographies. Note that much of the styling in
      `styles.html` will be ignored for EPUB, because of the conditional on
      `document-css`.  Setting the `document-css` variable will cause it
      not to be ignored.
    * HTML template:  Add abstract (#7588, Jannik Buhr, John MacFarlane).
      By default, a localized title (the word "Abstract") will be
      used, unless the variable `abstract-title` is set.
    * ConTeXt template:  Make title appear in PDF title bar.  This is
      recommended for accessibility reasons.  Note: doesn't work with macOS
      Preview.app.
    * `reference.pptx`: change to use 16:9 aspect ratio, Powerpoint's default.
    * Text.Pandoc.Writers:
      + Do not export `writeCustom` [API change]. This ensures that all
      writers exported in T.P.Writers are parameterized and work with any
      `PandocMonad` type. This is consistent with T.P.Readers, as
      `readCustom` is not exported from that module either.
    * Text.Pandoc.Writers.Shared:
      + `endsWithPlain` now returns True if the list ends with a list
      that ends with a Plain, and so on recursively (#7810).
    * Text.Pandoc.Class.IO:
      + `writeMedia`:  unescape percent-encoding in creating file path.
      This addresses a problem with spaces in image filenames
      when creating PDFs (#7819); it also affects `--extract-media`.
    * New internal module Text.Pandoc.Writers.Blaze, exporting `layoutMarkup`.
      This converts a blaze Html structure into a doclayout Doc Text.
    * Text.Pandoc.Extensions:
      + `parseFormatSpec`: cleaner error message for invalid extensions.
    * Text.Pandoc.MediaBag:
      + Fix bug in `extractMedia`, which caused the test for `..`
      in paths to fail, with the result that images with `..`
      in the path name could be extracted outside of the
      directory specified by `extractMedia`. It also led a check for
      `media` in resource paths to fail in the docx reader.
    * Text.Pandoc.Citeproc:
      + Avoid adding comma before an author-in-text citation in a note
      if it begins with a title (no author) (#7761).
      + Text.Pandoc.Citeproc.Locator now exports `toLocatorMap`,
      `LocatorInfo`, and `LocatorMap`.  The type of `parseLocator`
      has changed, so it now takes a `LocatorMap` rather than a `Locale`
      as parameter, and returns a `LocatorInfo` instead of a tuple.
      + Fix citation locator detection for German.  `toLocatorMap` now
      stores keys case-folded. We want to do a case-insensitive
      comparison when parsing locators, so that e.g. both
      `Chap.` and `chap.` work. Previously we case-folded terms
      when doing the lookup, but they weren't case-folded in the
      map itself, which led to locator-detection breaking for
      German (where the terms have uppercase letters).
    * Lua (Albert Krewinkel):
      + Allow single elements as singleton MetaBlocks/MetaInlines. Single
      elements should always be treated as singleton lists in the Lua
      subsystem.
      + Add `pandoc.template` module. The module provides a `compile`
      function to use strings as templates.
      + Add `pandoc.WriterOptions` constructor.
      + Add function `pandoc.write`.
      + Provide global `PANDOC_WRITER_OPTIONS` (#5221).
      + The function Text.Pandoc.Filter.applyFilters now takes a filter
      environment of type `Environment`, instead of a ReaderOptions value
      [API change].
      + The `Environment` type is exported from Text.Pandoc.Filter
      and allows to combine ReaderOptions and WriterOptions in a single
      value [API change].
      + Global, exported from Text.Pandoc.Lua, has a new type constructor
      `PANDOC_WRITER_OPTIONS` [API change].
      + Add constructors `pandoc.Blocks` and `pandoc.Inlines`.
      The functions convert their argument into a list of Block and Inline
      values, respectively. When applied to a string, they split the
      string into `Str` elements separated by `Space` or `SoftBreak`
      (#7712).
      + Support topdown traversals The traversal order of filters can now
      be selected by setting the key `traverse` of the filter to either
      `'topdown'` or `'typewise'`; the default remains `'typewise'`.
      Topdown traversals can be cut short by returning `false` as a
      second value from the filter function. No child-element of the
      returned element is processed in that case.
      + Marshal ReaderOptions field `extensions`, `track_changes` via JSON.
      Extensions are now available as a list of strings; the track-changes
      settings are given as the kebab-case representation used in JSON.
      + Allow binary (byte string) readers to be used with `pandoc.read`.
      + Use global state when parsing documents in `pandoc.read`.
      The function `pandoc.read` is updated to use the same state that was
      used while parsing the main input files. This ensures that log
      messages are preserved and that images embedded in the input are
      added to the mediabag.
      + Cleanup stack in `peekReadOptionsTable`. A ReaderOptions element was
      left on top of the stack when the `peekReadOptionsTable` function
      was invoked.
      + `walk` methods are added to `Pandoc`, `Block`, `Inline`,
      `Blocks`, `Inlines` values; the methods are similar to
      `pandoc.utils.walk_block` and `pandoc.utils.walk_inline`, but
      apply to filter to the element's contents.
      + Functions of name `Doc` are no longer accepted as alternatives for
      `Pandoc` filter functions. This functionality was undocumented.
      + Improve handling of empty caption, body by `from_simple_table`
      [#7776]). Create truly empty table caption and body when these are
      empty in the simple table.
      + Change representation of `TableHead`, `TableFoot`, and `Row` values
      (#7718).  The objects now also follow the principle that element
      attributes are accessible through the `.attr` field. Rows in `TableHead`
      and `TableFoot` are available via the `.rows` field. Row objects have a
      `.cells` field, containing the list of table cells.
      + [Simplify](Simplify) code of `pandoc.utils.stringify`. Minor behavior change:
      plain strings nested in tables are now included in the result string.
      + Simplify and deprecate function `pandoc.utils.equals`. The function
      is no longer required for element comparisons; it is now an alias
      for the `==` operator.
      + Add function `pandoc.utils.references` (#7752).
      + Add new library function `pandoc.utils.type`.  The function behaves
      like the default `type` function from Lua's standard library,
      but is aware of pandoc userdata types. A typical use-case would be
      to determine the type of a metadata value.
      + Fix return types of `blocks_to_inlines`, `make_sections`.
      Ensures the returned lists have the correct type (`Inlines` and
      `Blocks`, respectively).
      + Use more natural representation for Reference values
      Omit `false` boolean values, push integers as numbers.
    * Lua: use package pandoc-lua-marshal (#7719, Albert Krewinkel).
      The marshaling functions for pandoc's AST are extracted into a separate
      package. The package comes with a number of changes:
      + Pandoc's List module was rewritten in C, and error messages were
      improved.
      + Lists of `Block` and `Inline` elements are marshaled using the new
      list types `Blocks` and `Inlines`, respectively. These types
      currently behave identical to the generic List type, but give better
      error messages. This also opens up the possibility of adding
      element-specific methods to these lists in the future.
      + Elements of type `MetaValue` are no longer pushed as values which
      have `.t` and `.tag` properties. This was already true for
      `MetaString` and `MetaBool` values, which are still marshaled as Lua
      strings and booleans, respectively. Affected values:
    - `MetaBlocks` values are marshaled as a `Blocks` list;
    - `MetaInlines` values are marshaled as a `Inlines` list;
    - `MetaList` values are marshaled as a generic pandoc `List`s.
    - `MetaMap` values are marshaled as plain tables and no longer
      given any metatable.
      + `Cell` values are now marshaled as userdata objects; a constructor
      function for table cells is provided as `pandoc.Cell`.
      + The test suite for marshaled objects and their constructors has
      been extended and improved.
      + A bug in `Citation` objects, where setting a citation's suffix
      modified it's prefix, has been fixed.
      + Inlines, Blocks, and List objects now have an `__eq` metamethod,
      testing equality by comparing two lists element-wise.
    * Powerpoint tests: shorten lines by grouping tests (Albert
      Krewinkel). This makes the test output more pleasant to read
      in narrow terminal windows.
    * make check: check for unreleased dependencies.
    * Add `tools/build-and-upload-api-docs.sh`.
    * Update cabal description.
    * `MANUAL.txt`: Add section on EPUB styling.
    * `MANUAL.txt`: clarify "standard Markdown" as "original Markdown"
      (#7802, Martin Fischer).
    * `doc/custom-writers.md`: use filter to include source of example.
    * Add an example to `doc/custom-readers.md`.
    * Fix typo in `custom-readers.md` (#7722, Mauro Bieg).
    * `doc/jats.md`: add link to JATS documentation (Martin Fischer).
    * `doc/lua-filters.md`: many improvements (Albert Krewinkel,
      John MacFarlane).
    * Use commonmark-extensions 0.2.3. This allows a bare-word class attribute
      on fenced divs.
    * Use ipynb 0.2.
    * Use citeproc 0.6.0.1.
    * Use texmath 0.12.4.
    * Use doctemplates 0.10.0.1.
    [#]# pandoc 2.16.2 (2021-11-21)
    * Add interface for custom readers written in Lua (#7669).
      Users can now do `-f myreader.lua` and pandoc will treat the
      script `myreader.lua` as a custom reader, which parses an input
      string to a pandoc AST, using the pandoc module defined for
      Lua filters.  A sample custom reader can be found in `data/creole.lua`.
      Also see documentation in `doc/custom-readers.md`.
    * New module Text.Pandoc.Readers.Custom, exporting `readCustom` [API change].
    * Allow `plain` to be used in raw attribute syntax.
    * Accept empty `--metadata-file` (#7675).
      This was a regression from 2.15 behavior.
    * Markdown reader: Improve `inlinesInBalancedBrackets`.
      This is just a small improvement in terms of performance, but it's simpler
      and more direct code.  Also, we avoid parsing interparagraph spaces in
      balanced brackets, as the original did.
    * BibTeX reader: Properly handle commented lines in BibTeX/BibLaTeX (#7668).
    * RST reader: handle class attribute for for custom roles (#7699,
      willj-dev).  Previously the class attribute was ignored, and the name
      of the role used as the class.
    * DocBook reader:
      + Add `<titleabbr>` support (Rowan Rodrik van der Molen).
      + Support for `<indexterm>` (#7607, Rowan Rodrik van der Molen).
    * LaTeX reader:
      + Add rudimentary support for `\autoref` (#7693).
      + Add 'uri' class when parsing `\url`, for consistency
      with treatment of autolinks in other formats (#7672).
    * JATS reader: Capture `alt-text` in figures (#7703, Aner Lucero).
    * MediaWiki writer: use HTML spans for anchors when header has id (#7697).
      We need to generate a span when the header's ID doesn't match
      the one MediaWiki would generate automatically.  Note that MediaWiki's
      generation scheme is different from pandoc's (it uses uppercase letters,
      and `_` instead of `-`, for example).  This means that in going from
      markdown to mediawiki, we'll now get spans before almost every heading,
      unless explicit identifiers are used that correspond to the ones MediaWiki
      auto-generates.  This is uglier output but it's necessary for internal
      links to work properly.
    * Markdown writer: don't create autolinks when this loses information
      (#7692).  Previously we sometimes lost attributes when rendering links
      as autolinks.
    * Text.Pandoc.Readers.Metadata: allow multiple YAML documents when parsing
      YAML for `yamlBsToRefs`.  Some people use `---` as the end delimiter in
      YAML bibliography files, which causes the `yaml` library to emit an
      error unless we explicitly allow multiple YAML documents (and just
      consider the first).
    * JATS writer:
      + Ensure figures are wrapped with `<p>` in list items
      (Albert Krewinkel).  This prevents the generation of invalid output.
      + Add URL to element citation entries (Albert Krewinkel).
      The URL of a reference, if present, is added in tag `<uri>` to
      element-citation entries.
    * HTML writer: Don't create invalid `data-` attribute for empty
      attribute key (#7546).
    * LaTeX writer:
      + Babel mappings: use `ancientgreek` for `grc`.
      + With `-t latex-smart`, don't generate `\ldots` from ellipsis (#7674).
      Instead just use unicode ellipsis.
    * JATS template: fix `equal-contrib` attribute (Albert Krewinkel).
      The standard requires the value to be either `yes` or `no`, but is was
      set to `true` for authors who contributed equally.
    * reveal.js template: Add `disableLayout` variable (Christophe Dervieux).
    * Text.Pandoc.Error: sort errors in `handleError` by exit code
      (Albert Krewinkel).
    * Text.Pandoc.Writers.Shared: Improve toLegacyTable (#7683,
      Christian Despres).
    * Lua subsystem:
      + Include lpeg module (#7649, Albert Krewinkel).  Compiles the `lpeg`
      library (Parsing Expression Grammars For Lua) into
      the program.  Package maintainers may choose to rely on package
      dependencies to make lpeg available, in which case they can compile
      the with the constraint `lpeg +rely-on-shared-lpeg-library`.
      `lpeg` and `re` are always made available in global variables,
      without the need for a `require`.
      + Set `lpeg` and `re` as globals; allow shared lib access via `require`.
      The `lpeg` and `re` modules are loaded into globals of the respective
      name, but they are not necessarily registered as loaded packages. This
      ensures that
    - the built-in library versions are preferred when setting the globals,
    - a shared library is used if pandoc has been compiled without `lpeg`,
      and
    - the `require` mechanism can be used to load the shared library if
      available, falling back to the internal version if possible and
      necessary.
      + Fix argument order in constructor `pandoc.Cite` (Albert Krewinkel).
      This restores the old behavior; argument order had been switched
      accidentally in pandoc 2.15.
      + Add Pushable instance for `ReaderOptions` (Albert Krewinkel).
      + Allow to pass custom reader options to `pandoc.read` as an
      optional third argument (#7656, Albert Krewinkel).
      The object can either be a table or a ReaderOptions value
      like `PANDOC_READER_OPTIONS`. Creating new ReaderOptions objects is
      possible through the new constructor `pandoc.ReaderOptions`.
      + Display Pandoc values using their native Haskell representation
      (Albert Krewinkel).
      + Require latest hslua (2.0.1) (#7661, #7657, Albert Krewinkel).
      This fixes issues with
    - misleading error messages when a required function parameter is
      omitted;
    - absent properties still being listed in the output of `pairs`; and
    - alias accessing leading to errors instead of returning `nil`, e.g.
      with `(pandoc.Str '').identifier`.
      + Add missing space in "package not found" message (#7658, Albert
      Krewinkel).
    * Update build files (#7696, Fabián Heredia Montiel).
      Drop old windows 32-bit constraints.
      Update cabal `tested-with` field to correspond to `ci.yml` matrix
    * Remove unneeded package dependencies from benchmark target.
    * Require ghc >= 8.6, base >= 4.12.
      This allows us to get rid of the old custom prelude and
      some crufty cpp.  But the primary reason for this is that
      conduit has bumped its base lower bound to 4.12, making it
      impossible for us to support lower base versions.
    * Require Cabal 2.4.  Use wildcards to ensure that all pptx tests are
      included (#7677).
    * Update `bash_completion.tpl` (S.P.H.).
    * Add `data/creole.lua` as sample custom reader.
    * Add `doc/custom-readers.md` and `doc/custom-writers.md`.
    * `doc/lua-filters.md`: add section on global modules, including lpeg
      (Albert Krewinkel).
    * `MANUAL.txt`: update table of exit codes and corresponding errors
      (Albert Krewinkel).
    * Use latest texmath.
* Wed Nov 03 2021 [email protected]
  - Update pandoc to version 2.16.1.
    [#]# pandoc 2.16.1 (2021-11-02)
    * Docx reader:  don't let first line indents trigger block quotes (#7655).
      This fixes a regression introduced in pandoc 2.15.
    * Docx writer: use `getTimestamp` for modification times in
      reference.docx (#7654).  This ensures that when `SOURCE_DATE_EPOCH` is
      set, the modification times of files taken from the reference.docx will
      be set deterministically, allowing for reproducible builds.
    * Lua subsystem (Albert Krewinkel):
      + Load module `pandoc.path` on startup (#7524).  Previously the module
      always had to be loaded via `require 'pandoc.path'`.
      + Fix typo in SoftBreak constructor.
      + Re-add `content` property to Strikeout elements.
      Fixes a regression introduced in 2.15.
      + Be more forgiving when retrieving the Image `caption` property.
      Fixes a regression introduced in 2.15.
      + Display Attr values using their native Haskell representation.
      + Allow omitting the 2nd parameter in pandoc.Code constructor.
      Fixes a regression introduced in 2.15 which required users to always
      specify an Attr value when constructing a Code element.
      + Allow to compare, show Citation values.  Comparisons of Citation
      values are performed in Haskell; values are equal if they represent
      the same Haskell value. Converting a Citation value to a string
      now yields its native Haskell string representation.
      + Restore List behavior of MetaList (#7650).  Fixes a regression
      introduced in 2.16 which had MetaList elements lose
      the `pandoc.List` properties.
      + Restore `content` property on Header elements.
      + Ensure Block elements have all expected properties.
      + Ensure Inline elements have all expected properties.
    * Allow tasty-bench 0.3.x.
* Mon Nov 01 2021 [email protected]
  - Update pandoc to version 2.16.
    Upstream has edited the change log file since the last release in
    a non-trivial way, i.e. they did more than just add a new entry
    at the top. You can review the file at:
    http://hackage.haskell.org/package/pandoc-2.16/src/changelog.md
* Thu Oct 07 2021 [email protected]
  - relax dep on skylighting
* Sun Aug 22 2021 [email protected]
  - Update pandoc to version 2.14.2.
    [#]# pandoc 2.14.2 (provisional)
    * Allow `--slide-level=0` (#7476). When the slide level is set
      to 0, headings won't be used at all in splitting the document
      into slides. Horizontal rules must be used to separate slides.
    * Add RTF reader (#3982). `rtf` is now supported as an input
      format as well as an output format. New module
      Text.Pandoc.Readers.RTF (exporting `readRTF`). [API change]
    * HTML reader:  treat comments as blank when parsing (#7482).
    * Markdown reader:
      + Fix raw LaTeX injection issue (#7497). Using a code block
      containing `\end{verbatim}`, one could inject raw TeX into a
      LaTeX document even when `raw_tex` is disabled. Thanks to
      Augustin Laville for noticing the bug.
      + Multimarkdown sub- and superscripts (#5512, OCzarnecki).
      Added an extension `short_subsuperscripts` which modifies
      the behavior of `subscript` and `superscript`, allowing
      subscripts or superscripts containing only alphanumerics
      to end with a space character (eg. `x^2 = 4` or `H~2 is
      combustible`).  This improves support for multimarkdown.
    * RST reader: Fix `:literal:` includes (#7513).  These should create
      code blocks, not insert raw RST.
    * LaTeX reader:
      + Proper implicit grouping around environment macros.
      + Support `\global` before `\def`, `\let`, etc. (#7494).
      + Fix scope for LaTeX macros (#7494). They should by default
      scope over the group in which they are defined (except `\gdef`
      and `\xdef`, which are global). In addition, environments must
      be treated as groups.
      + Improve handling of plain TeX macro primitives (#7474).
      Fixed semantics for `\let`.
      + Implement `\edef`, `\gdef`, and `\xdef`.
    * Docx reader: Improve docx reader's robustness in extracting
      images (#7511). The docx reader made some assumptions about
      how docx containers were laid out that were not always true, with
      the result that some images in documents did not get
      extracted.
    * LaTeX writer: Increase table column width precision (#7466,
      Peter Fabinski). In some cases, the rounding performed by the
      LaTeX table writer would introduce visible overrun outside
      the text area. This adds two more decimal places to the width
      values.
    * Powerpoint writer:
      + Include image title in description (#7352, Emily Bourke). The
      image title (i.e. `![alt text](link "title")`) was previously
      ignored when writing to pptx. This commit includes it in
      PowerPoint's description of the image, along with the link.
      + Select layouts from reference doc by name (Emily Bourke). Until
      now, users had to make sure that their reference doc contains
      layouts in a specific order: the first four layouts in the file
      had to have a specific structure. Now the layout selection uses
      the layout names rather than order: users must make sure their
      reference doc contains four layouts with specific names, and if
      a layout with the right name isn’t found pandoc will emit
      a warning and use the corresponding layout from the default
      reference doc as a fallback.
    * Docx writer: be sensitive to the `native_numbering` extension
      (#7499).  Figure and table numbers are now only included if
      `native_numbering` is enabled.  (By default it is disabled.)
      This is a behavior change with respect to 2.14.1, but the
      default behavior is now that of previous versions.  The
      change was necessary to avoid incompatibilities between
      pandoc's native numbering and third-party cross reference
      filters like pandoc-crossref.
    * RTF writer:
      + Omit `\bin` in `\pict`. According to the spec, this is not
      needed or wanted when the data is in hexadecimal format, as
      here.
      + Emit `\outlinelevel`` for section headings.
    * RTF template: specify font family for fixed-width font f1.
      According to the spec, this is mandatory.
    * LaTeX writer: Use ulem for underline (#7351). ulem is
      conditionally included already when the `strikeout` variable
      is set, so we set this when there is underlined text, and use
      `\uline` instead of `\underline`. This fixes wrapping for
      underlined text.
    * Text.Pandoc.Citeproc:
      + Revise citeproc code to fit new citeproc 0.5 API (thanks to
      Benjamin Bray). Linkification of URLs in the bibliography
      is now done in the citeproc library, depending on the
      setting of an option.  We set that option depending on the
      value of the metadata field `link-bibliography` (defaulting
      to true, for consistency with earlier behavior). If a DOI,
      PMID, PMCID, or URL field is present but not explicitly
      rendered, the title (or if no title, the whole entry) is
      hyperlinked. These changes implement the recommendations
      from the draft CSL v1.0.2 spec (Appendix VI):
      <https://github.com/citation-style-language/documentation/blob/master/specification.rst#appendix-vi-links>
      + Avoid odd handling of quotes. Recent citeproc changes
      allow us to ignore Quoted elements; citeproc now uses its own
      method for represented quoted things, and only localizes and
      flipflops quotes it adds itself. Convert Quoted in bib
      entries to special Spans before passing them off to
      citeproc. This ensures that we get proper localization and
      flipflopping if, e.g., quotes are used in titles
      (jgm/citeproc#87).
      + Removed quote localization from citeproc processing.
      This is now done in citeproc itself.
    * Text.Pandoc.Logging: Add PowerpointTemplateWarning log message
      type [API change] (Emily Bourke).
    * Text.Pandoc.Extension: Add `Ext_short_subsuperscripts`
      constructor to `Extension` [API change] (OCzarnecki).
    * Various sample.lua editorial fixes (#7493, #7487, William
      Lupton).
    * Bump base-compat version so we get compatibility with base 4.12.
    * Use Prelude from base-compat for ghc 8.4 too.
    * Add haskell-language-server to shell.nix (#7496, Emily Bourke).
    * Tests.Helpers: export testGolden and use it in RTF reader.
      This gives a diff output on failure.
    * Remove obsolete and incorrect sentence in `--slide-level` docs.
    * Add internal module Text.Pandoc.Network.HTTP, exporting
      `urlEncode`.
    * Text.Pandoc.Parsing: `parseFromString`: preserve at least
      the source directory (#7464). Previously we just set the
      source name to "chunk" when parsing from strings, to avoid
      misleading source positions. This had the side effect that
      `rebase_relative_paths` would break inside sections that
      were parsed as strings. So, now we use
      "ORIGINAL_SOURCE_PATH_chunk" instead of just "chunk".
    * Text.Pandoc.MIME: use image/x-xcf instead of application/x-xcf
      (#7454).
    * Don’t compare `cdLine` in OOXML golden tests (Emily Bourke).
      The `cdLine` field gives the line of the file some CData was
      found on, which reflects irrelevant formatting differences.
    * Provide more detailed XML diff in tests (Emily Bourke).
    * OOXML tests: silence warnings. These can make the test output
      confusing, making people think tests are failing when they're
      passing.
    * INSTALL.md: Add GitLab CI/CD example (#7448, Veratyr).
    * MANUAL.txt
    - Clarifications (William Lupton).
    - Add a note on security risks of include directives.
    * Document use of the 'underline' class (#7492, #7484, William
      Lupton).
    * Add a FAQ about the "Cannot allocate memory" error on M1 macs.
    * Use texmath 0.12.3.1.
    * Use released citeproc 0.5.
    * Remove dependency on HTTP package (#7456, mt_caret).
* Sun Jul 25 2021 [email protected]
  - Include manpage in distribution.
* Mon Jul 19 2021 [email protected]
  - Update pandoc to version 2.14.1.
    [#]# pandoc 2.14.1 (2021-07-18)
    * Text.Pandoc.ImageSize: Add Tiff constructor for ImageType (#7405)
      [Minor API change].  This allows pandoc to get size information from
      tiff images.
    * Markdown reader:  don't try to read contents in self-closing HTML tag.
      Previously we had problems parsing raw HTML with self-closing
      tags like `<col/>`. The problem was that pandoc would look
      for a closing tag to close the markdown contents, but the
      closing tag had, in effect, already been parsed by `htmlTag`.
    * LaTeX reader:
      + Avoid trailing hyphen in translating languages (#7447).
      Previously `\foreignlanguage{english}` turned into `<span lang="en-">`.
      The same issue affected Arabic.
      + Support `\cline` in LaTeX tables (#7442).
      + Improved parsing of raw LaTeX from Text streams (`rawLaTeXParser`,
      used to read LaTeX in Markdown files, #7434).  We now use source
      positions from the token stream to tell us how much of the text stream
      to consume.  Getting this to work required a few other changes to
      make token source positions accurate.
    * DocBook reader:
      + Handle images with imageobjectco elements (#7440).
      + Add support for citerefentry (#7437, Jan Tojnar).
    * RST reader: fix regression with code includes (#7436).
      With the recent changes to include infrastructure,
      included code blocks were getting an extra newline.
    * HTML reader:
      + Recognize data-external when reading HTML img tags (#7429,
      Michael Hoffmann).  Preserve all attributes in img tags.  If attributes
      have a `data-` prefix, it will be stripped.  In particular, this
      preserves a `data-external` attribute as an `external` attribute in
      the pandoc AST.
      + Add col, colgroup to 'closes' definitions
    * HTML writer:
      + Remove duplicated alt text in HTML output (Aner Lucero).
      + Remove `aria-hidden` when explicit alt text is provided (Aner Lucero).
      + Set boolean values for reveal.js variables.
    * Docx writer:
      + Add table numbering for captioned tables.
      The numbers are added using fields, so that Word can
      create a list of tables that will update automatically.
      + Support figure numbers.  These are set up in such a way that they
      will work with Word's automatic table of figures (#7392).
    * Markdown writer: put space between Plain and following fenced Div
      (#4465).
    * EPUB writer: Don't incorporate externally linked images in EPUB documents
      (#7430, Michael Hoffmann).  Just as it is possible to avoid incorporating
      an image in EPUB by passing `data-external="1"` to a raw HTML snippet,
      this makes the same possible for native Images, by looking for an
      associated `external` attribute.
    * Text.Pandoc.PDF:
      + Fix `svgIn` path error (#7431).  We were duplicating
      the temp directory; this didn't cause problems on macOS or linux
      because there we use absolute paths for the temp directory.
      But on Windows it caused errors converting SVG files.
      + `convertImage`: normalize paths (#7431).  This will avoid paths
      on Windows with mixed path separators.
    * Text.Pandoc.Class: Always use / when adding directory to image destination
      with `extractMedia`, even on Windows.
    * Text.Pandoc.Citeproc:
      + Allow `$` characters in bibtex keys (#7409).
      + Set proper initial source name in parsing BibTeX (for better error
      messages.)
      + Revamp note citation handling (#7394).  Use latest
      citeproc, which uses a Span with a class rather than a Note for notes.
      This helps us distinguish between user notes and citation notes.  Don't
      put citations at the beginning of a note in parentheses.  Fix small bug
      in handling of citations in notes, which led to commas at the end of
      sentences in some cases.
      + Cleanup and efficiency improvement in `deNote`.
      + Improve punctuation moving with `--citeproc`.  Previously, using
      `--citeproc` could cause punctuation to move in quotes even when
      there aer no citations. This has been changed; punctuation moving
      is now limited to citations.  In addition, we only move footnotes
      around punctuation if the style is a note style, even if
      `notes-after-punctuation` is `true`.
    * Use citeproc 0.10. This helps improve note citations (see above)
      and eliminates double hyperlinks in author-in-text citations.
      Author-only citations are no longer hyperlinked.  See jgm/citeproc#77.
      It also fixes moving of punctuation inside quotes to conform to
      the CSL spec: only comma and period are moved, not question
      mark or exclamation point.
    * Text.Pandoc.Error: fix line calculations in reporting parsec errors.
      Also remove a spurious initial newline in the error report.
    * Use doctemplates 0.4.1, which gives us better support for boolean
      variable values.  Previously `$if(foo)$` would evaluate to true
      for variables with boolean `false` values, because it cared only
      about the string rendering (#7402).
    * Require commonmark-pandoc >= 0.2.2.1.
      This fixes task lists with multiple paragraphs.
    * Use skylighting 0.11.
    * CSS in HTML template: reset overflow-wrap on code blocks
      (Mauro Bieg, #7423).
    * LaTeX template: Revert change in PR #7295: "move title, author, date up
      to top of preamble." The change caused problem for people who used
      LaTeX commands defined defined later in the preamble in the title
      or author fields (#7422).
    * Add `doc/faqs.md`.  This is imported from the website; in the future the
      website version will be drawn from here.
      Added a FAQ on the use of `\AtEndPreamble` for cases when the contents of
      `header-includes` need to refer to definitions that come later in the
      preamble.  See #7422.
    * Upgrade Debian 10 AMI for build-arm.sh.
    * CircleCI: change to using xcode 11.1.0 (macOS 10.14.4).
      We previously built on 10.13, but 10.13 no longer gets
      security updates and CirclCI is deprecating.

  - Update pandoc to version 2.14.0.3.
    [#]# pandoc 2.14.0.3 (2021-06-22)
    * Text.Pandoc.MediaBag `insertMediaBag`: ensure we get a sane mediaPath
      for URLs (#7391).  In earlier 2.14.x versions, we'd get
      incorrect paths for resources downloaded from URLs when the
      media are extracted (including in PDF production).
    * Text.Pandoc.Parsing: improve `emailAddress` (#7398).
      Previously the parser would accept characters in domains
      that are illegal in domains, and this sometimes caused it
      to gobble bits of the following text.
    * txt2tags reader: modify the email address parser so
      it still includes form parameters, even after the change to
      `emailAddress` in Text.Pandoc.Parsing.
    * Text.Pandoc.Readers.Metadata: Fix regression with comment-only YAML
      metadata blocks (#7400).
    * reveal.js writer and template: better handling of options.  Previously
      it was impossible to specify false values for options that default to
      true (e.g. `center`); setting the option to false just caused the portion
      of the template setting the option to be omitted.  Now we prepopulate
      all the variables with their default values, including them all
      unconditionally and allowing them to be overridden.
    * Markdown writer: Fix regression in code blocks with attributes (#7397).
      Code blocks with a single class but nonempty attributes
      were having attributes drop as a result of #7242.
    * LaTeX writer:
      + Add strut at end of minipage if it contains line breaks.
      Without them, the last line is not as tall as it should be in
      some cases.
      + Always use a minipage for cells with line breaks, when
      width information is available (#7393).  Otherwise the way we treat them
      can lead to content that overflows a cell.
      + Use `\strut` instead of `~` before `\\` in empty line.
    * Use lts-18.0 stack resolver.
    * Require skylighting 0.10.5.2 (adding support for Swift).
    * Require commonmark 0.2.1.
    * Rephrase section on unsafe HTML in manual.
    * Create SECURITY.md

  - Update pandoc to version 2.14.0.2.
    [#]# pandoc 2.14.0.2 (2021-06-13)
    * Fix MediaBag regressions (#7345). iIn the 2.14 release `--extract-media`
      stopped working as before; there could be mismatches between the
      paths in the rendered document and the extracted media.
      This patch makes several changes that restore the earlier behavior
      (while keeping the same API).  The `mediaPath` in 2.14 was always
      constructed from the SHA1 hash of the media contents.  Now, we
      preserve the original path unless it's an absolute path or contains
      `..` segments (in that case we use a path based on the SHA1 hash of
      the contents).
      In Text.Pandoc.MediaBag, `mediaDirectory` and `mediaItems` now use the
      `mediaPath`, rather than the mediabag key, for the first component of the
      tuple.  This makes more sense, I think, and fits with the documentation of
      these functions; eventually, though, we should rework the API so that
      `mediaItems` returns both the keys and the MediaItems.
      In Text.Pandoc.Class.IO, rewriting of source paths in `extractMedia` has
      been fixed.
      In Text.Pandoc.Class.PandocMonad, `fillMediaBag` has been modified so that
      it doesn't modify image paths (that was part of the problem in #7345).
      We now do path normalization (e.g. `\` separators on Windows) in
      writing the media.
    * Text.Pandoc.PDF:
      + Text.Pandoc.PDF: Fix regression in 2.14 for generation of PDFs with
      SVGs (#7344).
      + Only print relevant part of environment on `--verbose`.  Since
      `--verbose` output might be put in an issue, we want to avoid
      spilling out secrets in environment variables.
    * Markdown reader: fix pipe table regression in 2.11.4 (#7343).
      Previously pipe tables with empty headers (that is, a header
      line with all empty cells) would be rendered as headerless
      tables.  This broke in 2.11.4.  The fix here is to produce an
      AST with an empty table head when a pipe table has all empty
      header cells.
    * LaTeX reader: don't allow optional `*` on symbol control sequences
      (#7340).  Generally we allow optional starred variants of LaTeX commands
      (since many allow them, and if we don't accept these explicitly,
      ignoring the star usually gives acceptable results).  But we
      don't want to do this for `\(*\)` and similar cases.
    * Docx reader: handle absolute URIs in Relationship Target (#7374).
    * Docx writer: fix handling of empty table headers (Albert Krewinkel,
      [#7369]).  A table header which does not contain any cells is now treated as
      an empty header.
    * LaTeX writer: Fix regression in table header position (#7347).
      In recent versions the table headers were no longer bottom-aligned
      (if more than one line).  This patch fixes that by using minipages
      for table headers in non-simple tables.
    * CommonMark writer:
      + Do not use simple class for fenced-divs (Jan Tojnar, amends #7242.)
      + Do not throw away attributes when `Ext_attributes` is enabled.
      `Ext_attributes` covers at least the following:
      `Ext_fenced_code_attributes`, `Ext_header_attributes`,
      `Ext_inline_code_attributes`, `Ext_link_attributes`.
    * Markdown writer:
      + Allow `pipe_tables` to be disabled for commonmark formats
      (`commonmark_x`, `gfm`) (#7375).
      + Re-use functions from Text.Pandoc.Markdown.Inline (Jan Tojnar).
    * DocBook writer: Remove non-existent admonitions (Jan Tojnar).
      `attention`, `error` and `hint` are reStructuredText specific.
    * HTML writer: Don't omit width attribute on div (#7342).
    * Text.Pandoc.MIME, `extensionFromMimeType`: add a few special cases.
      When we do a reverse lookup in the MIME table, we just get the
      last match, so when the same mime type is associated with several
      different extensions, we sometimes got weird results, e.g. `.vs`
      for `text/plain`.  These special cases help us get the most standard
      extensions for mime types like `text/plain`.
    * Lua utils: fix handling of table headers in `from_simple_table` (Albert
      Krewinkel, #7369).  Passing an empty list of header cells now results
      in an empty table header.
    * Text.Pandoc.Citeproc:
      + Avoid duplicate classes and attributes on references div.
      + Fix regression in citeproc processing (#7376).  If inline
      references are used (in the metadata `references` field), we
      should still only include in the bibliography items that are
      actually cited (unless `nocite` is used).
    * Require citeproc 0.4.0.1.  This fixes a bug which led to doubled
      "et al." in some (rare) circumstances.
    * MANUAL.txt:
      + Mention GladTeX for EPUB export (Sebastian Humenda).
      This updates the manual and the web site about the GladTeX usage.
      + More details and a useful link for YAML syntax.
    * CONTRIBUTING.md: update modules overview (Albert Krewinkel).
    * using-the-pandoc-api.md: switch from String to Text (Albert Krewinkel).
* Wed Jun 02 2021 [email protected]
  - Update pandoc to version 2.14.0.1.
    Upstream has edited the change log file since the last release in
    a non-trivial way, i.e. they did more than just add a new entry
    at the top. You can review the file at:
    http://hackage.haskell.org/package/pandoc-2.14.0.1/src/changelog.md
* Sun May 30 2021 [email protected]
  - Update pandoc to version 2.14.
    [#]# pandoc 2.14 (2021-05-28)
    * Change reader types, allowing better tracking of source positions
      [API change].  Previously, when multiple file arguments were provided,
      pandoc simply concatenated them and passed the contents to the readers,
      which took a Text argument.  As a result, the readers had no way of knowing
      which file was the source of any particular bit of text.  This meant that
      we couldn't report accurate source positions on errors or include accurate
      source positions as attributes in the AST.  More seriously, it meant that
      we couldn't resolve resource paths relative to the files containing them
      (see e.g. #5501, #6632, #6384, #3752).
    * Add `rebase_relative_paths` extension (#3752).  When enabled, this
      extension rewrites relative image and link paths by prepending
      the (relative) directory of the containing file.  This
      behavior is useful when your input sources are split
      into multiple files, across several directories, with files
      referring to images stored in the same directory.  The
      extension can be enabled for all markdown and commonmark-based formats.
    * Add Text.Pandoc.Sources (exported module), with a `Sources` type and a
      `ToSources` class.  A `Sources` wraps a list of `(SourcePos, Text)` pairs
      [API change]. A parsec `Stream` instance is provided for `Sources`.  The
      module also exports versions of parsec's `satisfy` and other Char parsers
      that track source positions accurately from a `Sources` stream (or any
      instance of the new `UpdateSourcePos` class).
    * Text.Pandoc.Parsing
      + Export the modified Char parsers defined in Text.Pandoc.Sources
      instead of the ones parsec provides.  Modified parsers to use a
      `Sources` as stream [API change].
      + Improve include file functions [API change].  Remove old
      `insertIncludedFileF`.  Give `insertIncludedFile` a more general type,
      allowing it to be used where `insertIncludedFileF` was.
      + Add parameter to the `citeKey` parser from
      Text.Pandoc.Parsing, which controls whether the `@{..}`
      syntax is allowed [API change].
    * Text.Pandoc.Error: Modified the constructor `PandocParsecError` to take a
      `Sources` rather than a `Text` as first argument, so parse error locations
      can be accurately reported.
    * Fix source position reporting for YAML bibliographies (#7273).
    * Issue error message when  reader or writer format is malformed
      (#7231).  Previously we exited with an error status but (due to a bug)
      no message.
    * Smarter smart quotes (#7216, #2103).  Treat a leading `"` with no
      closing `"` as a left curly quote.  This supports the practice, in
      fiction, of continuing paragraphs quoting the same speaker without an
      end quote.  It also helps with quotes that break over lines in line blocks.
    * Markdown reader:
      + Use MetaInlines not MetaBlocks for multimarkdown metadata fields.
      This gives better results in converting to e.g.  pandoc markdown.
      + Implement curly-brace syntax for Markdown citation keys (#6026).
      The change provides a way to use citation keys that contain
      special characters not usable with the standard citation key syntax.
      Example: `@{foo_bar{x}'}` for the key `foo_bar{x}`.  It also allows
      separating citation keys from immediately following text, e.g. `@{foo}A`.
    * RST reader:
      + Seek include files in the directory of the file
      containing the include directive, as RST requires (#6632).
      + Use `insertIncludedFile` from Text.Pandoc.Parsing
      instead of reproducing much of its code.
    * Org reader: Resolve org includes relative to the directory containing the
      file containing the INCLUDE directive (#5501).
    * ODT reader: Treat tabs as spaces (#7185, niszet).
    * Docx reader:
      + Add handling of vml image objects (#7257, mbrackeantidot).
      + Support new table features (Emily Bourke, #6316):  column
      spans, row spans, multiple header rows, table description
      (parsed as a simple caption), captions, column widths.
    * LaTeX reader:
      + Improved siunitx support (#6658, #6620).
      + Better support for `\xspace` (#7299).
      + Improve parsing of `\def` macros.  We previously set "verbatim mode"
      even for parsing the initial `\def`; this caused problems
      for `\def` nested inside another `\def`.
      + Implement `\newif`.
    * ConTeXt writer: improve ordered lists (#5016, Denis Maier).
      Change ordered list from itemize to enumerate.  Add new
      itemgroup for ordered lists.  Remove manual insertion of
      width attributes.  Use tabular figures in ordered list
      enumerators.
    * HTML reader:
      + Don't fail on unmatched closing "script" tag (Albert Krenkel, #7282).
      + Keep h1 tags as normal headers (#2293, Albert Krewinkel).
      The tags `<title>` and `<h1 class="title">` often contain the same
      information, so the latter was dropped from the document. However, as
      this can lead to loss of information, the heading is now always
      retained.  Use `--shift-heading-level-by=-1` to turn the `<h1>`
      into the document title, or a filter to restore the previous behavior.
      + Handle relative lengths (e.g. `2*`) in HTML column widths (#4063).
      See <https://www.w3.org/TR/html4/types.html#h-6.6>.
    * DocBook/JATS readers:
      + Fix mathml regression caused by the switch in XML libraries (#7173).
      + Fix "phrase" in DocBook: take classes from "role" not "class" (#7195).
    * DocBook reader: ensure that first and last names are separated (#6541).
    * Jira reader (Albert Krewinkel, #7218):
      + Support "smart" links: `[alias|https://example.com|smart-card]` syntax.
      + Allow spaces and most unicode characters in attachment links.
      + No longer require a newline character after `{noformat}`.
      + Only allow URI path segment characters in bare links.
      + The `file:` schema is no longer allowed in bare links; these
      rarely make sense.
    * Plain writer: handle superscript unicode minus (#7276).
    * LaTeX writer:
      + Better handling of line breaks in simple tables (#7272).
      Now we also handle the case where they're embedded in other elements,
      e.g. spans.
      + For beamer output, support `exampleblock` and `alertblock` (#7278).
      A block will be rendered as an `exampleblock` if the heading
      has class `example` and an `alertblock` if it has class `alert`.
      + Separate successive quote chars with thin space (#6958,
      Albert Krewinkel).  Successive quote characters are separated with
      a thin space to improve readability and to prevent unwanted ligatures.
      Detection of these quotes sometimes had failed if the second quote
      was nested in a span element.
      + Separate successive quote chars with thin space (#6958, Albert
      Krewinkel).
    * EPUB Writer: Fix belongs-to-collection XML id choice (#7267, nuew).
      The epub writer previously used the same XML id for both the book
      identifier and the epub collection. This causes an error on epubcheck.
    * BibTeX/BibLaTeX writer: Handle `annote` field (#7266).
    * ZimWiki writer: allow links and emphasis in headers (#6605,
      Albert Krewinkel).
    * ConTeXt writer:
      + Support blank lines in line blocks (#6564, Albert Krewinkel,
      thanks to @denismaier).
      + Use span identifiers as reference anchors (#7246, Albert Krewinkel).
    * HTML writer:
      + Keep attributes from code nested below `pre` tag (#7221,
      Albert Krewinkel).  If a code block is defined with `<pre><code
      class="language-x">…</code></pre>`, where the `<pre>` element has no
      attributes, then the attributes from the `<code>` element are used
      instead. Any leading `language-` prefix is dropped in the code's
      `class` attribute are dropped to improve syntax highlighting.
      + Ensure headings only have valid attribs in HTML4 (#5944, Albert
      Krewinkel).
      + Parse `<header>` as a Div (Albert Krewinkel).
    * Org writer:
      + Inline latex envs need newlines (#7252, tecosaur).
      As specified in https://orgmode.org/manual/LaTeX-fragments.html, an
      inline \begin{}...\end{} LaTeX block must start on a new line.
      + Use LaTeX style maths deliminators (#7196, tecosaur).
    * JATS writer (Albert Krewinkel):
      + Use either styled-content or named-content for spans (#7211).
      If the element has a content-type attribute, or at least one class,
      then that value is used as `content-type` and the span is put inside
      a `<named-content>` element. Otherwise a `<styled-content>` element
      is used instead.
      + Reduce unnecessary use of `<p>` elements for wrapping (#7227).
      The `<p>` element is used for wrapping in cases were the contents
      would otherwise not be allowed in a certain context. Unnecessary
      wrapping is avoided, especially around quotes (`<disp-quote>` elements).
      + Convert spans to `<named-content>` elements (#7211).  Spans with
      attributes are converted to `<named-content>` elements instead of
      being wrapped with `<milestone-start/>` and `<milestone-end>`
      elements. Milestone elements are not allowed in documents using the
      articleauthoring tag set, so this change ensures the creation of valid
      documents.
      + Add footnote number as label in backmatter (#7210).  Footnotes in the
      backmatter are given the footnote's number as a label.  The
      articleauthoring output is unaffected from this change, as footnotes
      are placed inline there.
      + Escape disallows chars in identifiers.  XML identifiers must start
      with an underscore or letter, and can contain only a limited set
      of punctuation characters. Any IDs not adhering to these rules are
      rewritten by writing the offending characters as `Uxxxx`,
      where `xxxx` is the character's hex code.
    * Jira writer:  use `{color}` when span has a color attribute
      (Albert Krewinkel, tarleb/jira-wiki-markup#10).
    * Docx writer:
      + Autoset table width if no column has an explicit width (Albert
      Krewinkel).
      + Extract Table handling into separate module (Albert Krewinkel).
      + Support colspans and rowspans in tables (Albert Krewinkel, #6315).
      + Support multirow table headers (Albert Krewinkel).
      + Improve integration of settings from reference.docx (#1209).
      This change allows users to create a reference.docx that
      sets `w:proofState` for spelling or grammar to `dirty`,
      so that spell/grammar checking will be triggered on the
      generated docx.
      + Copy over more settings from reference.docx (#7240).  From settings.xml
      in the reference-doc, we now include: `zoom`, `embedSystemFonts`,
      `doNotTrackMoves`, `defaultTabStop`, `drawingGridHorizontalSpacing`,
      `drawingGridVerticalSpacing`, `displayHorizontalDrawingGridEvery`,
      `displayVerticalDrawingGridEvery`, `characterSpacingControl`,
      `savePreviewPicture`, `mathPr`, `themeFontLang`, `decimalSymbol`,
      `listSeparator`, `autoHyphenation`, `compat`.
      + Set zoom to 100% by default in settings.xml.
      + Align math options more with current Word defaults (e.g.  Cambria Math
      font).
      + Remove `rsid`s from default settings.xml.  Word will add these
      when revisions are made.
    * Ms writer: Handle tables with multiple paragraphs (#7288).
      Previously they overflowed the table cell width.  We now set line lengths
      per-cell and restore them after the table has been written.
    * Markdown writer:
      + Use cleaner braceless syntax for code blocks with a
      single class (#7242, Jan Tojnar).
      + Add quotes properly in markdown YAML metadata fields (#7245).
      This fixes a bug, which caused the writer to look at the *last*
      rather than the *first* character in determining whether quotes
      were needed.  So we got spurious quotes in some cases and
      didn't get necessary quotes in others.
      + Use `@{..}` syntax for citations when needed.
      + Use fewer unneeded escapes for `#` (see #6259).
      + Improve escaping of `@`.  We need to escape literal `@` before
      `{` because of the new citation syntax.
    * Commonmark writer: Use backslash escapes for `<` and `|`...
      instead of entities (#7208).
    * Powerpoint writer: allow `monofont` to be specified in metadata
      (#7187).
    * LaTeX template:
      + Use non-starred names for xcolor color names (#6109).
      This should make svgnames and x11names work properly.
      + Fix bad vertical spacing after bibliography (#7234, badumont).
      + List of figures before list of tables (#7235, Julien Dutant).
      + Move CSL macro definitions before header-includes so they can be
      overridden (#7286).
      + Improve treatment of CSL `entry-spacing` (#7296).
      Previously with the default template settings (`indent` variable
      not set), we would get interparagraph spaces separating bib
      entries even with `entry-spacing="0"`.  On the other hand,
      setting `entry-spacing="2"` gave ridiculously large spacing.
      This change makes the spacing caused by `entry-spacing` a multiple
      of `\parskip` by default, which gives aesthetically reasonable
      output.  Those who want a larger or smaller unit (e.g. because
      they use `indent` which sets `\parskip` to 0) may
      `\setlength{\cslentryspacingunit}{10pt}` in header-includes
      to override the defaults.
      + Move title, author, date up to top of preamble (#7295).
      This allows header-includes to use them, and puts them
      in a position where you can see them immediately.
      + Define commands for zero width non-joiner character
      (#6639, Albert Krewinkel).  The zero-width non-joiner character
      is used to avoid ligatures (e.g. in German).
    * ConTeXt template: List of figures before list of tables (#7235,
      Julien Dutant).
    * reveal.js template:
      + Support `toc-title` (#7171, Florian Kohrt).
      + Use `hash: true` by default rather than `history: true` (#6968).
    * HTML-based slide shows: add support for `institute` (#7289, Thomas
      Hodgson).
    * Text.Pandoc.Extensions: Add constructor `Ext_rebase_relative_paths` to
      `Extensions` [API change].
    * Text.Pandoc.XML.Light: add Eq, Ord instances for Content,
      Element, Attr, CDataKind [API change].
    * Text.Pandoc.MediaBag:
      + Change type to use a `Text` key instead of `[FilePath]`.
      We normalize the path and use `/` separators for consistency.
      + Export `MediaItem` type [API change].
      + Change `MediaBag` type to a map from Text to MediaItem [API change].
      + `lookupMedia` now returns a `MediaItem` [API change].
      + Change `insertMedia` so it sets the `mediaPath` to a filename based on
      the SHA1 hash of the contents.  This will be used when contents
      are extracted.
    * Text.Pandoc.Class.PandocMonad:
      + Remove `fetchMediaResource` [API change].  Use `fetchItem` to get
      resources in `fillMediaBag`.
      + Add informational message in `downloadOrRead` indicating what path
      local resources have been loaded from.
    * Text.Pandoc.Logging:
      + Remove single quotes around paths in messages.
      + Add LoadedResource constructor to LogMessage [API change].
      This is for INFO-level messages telling where image data has been
      loaded from.  (This can vary because of the resource path.)
    * Text.Pandoc.Asciify: simplify code and export `toAsciiText` [API change].
      Instead of encoding a giant (and incomplete) map, we now
      just use unicode-transforms to normalize the text to
      a canonical decomposition, and manipulate the result.
    * App: allow tabs expansion even if file-scope is used (Albert Krewinkel,
      [#6709]).  Tabs in plain-text inputs  are now handled correctly, even if
      the `--file-scope` flag is used.
    * Add new internal module Text.Pandoc.Writers.GridTable (Albert Krewinkel).
    * Text.Pandoc.Highlighting: Change type of `languagesByExtension`, adding
      a parameter for a `SyntaxMap` [API change] (Jan Tojnar, #7241).
      Languages defined using `--syntax-definition` were not recognized by
      `languagesByExtension`.  This patch corrects that, allowing the writers
      to see all custom definitions.  The LaTeX writer still uses the default
      syntax map, but that's okay in that context, since
      `--syntax-definition` won't create new listings styles.
    * Text.Pandoc.Citeproc:
      + Ensure that CSL-related attributes are passed on to a Div with id
      'refs'.  Otherwise things like `entry-spacing` won't work when
      such Divs are used.
      + Use metadata's `lang` for the lang parameter of citeproc, overriding
      `localeLanguage`.
      + Recognize locators spelled with a capital letter (#7323).
      + Add a comma and a space in front of the suffix if it doesn't start
      with space or punctuation (#7324).
      + Don't detect math elements as locators (#7321).
    * Remove Text.Pandoc.BCP47 module [API change].  Use types and functions
      from UnicodeCollation.Lang instead.  This is a richer implementation
      of BCP 47.
    * Text.Pandoc.Shared:
      + Fix regression in grid tables for wide characters (#7214).
      In the translation from String to Text, a char-width-sensitive
      `splitAt'` was dropped.  This commit reinstates it and uses it to make
      `splitTextByInstances` char-width sensitive.
      + Add `getLang` (formerly in the now-removed BCP47) [API change].
    * Text.Pandoc.SelfContained: use `application/octet-stream`
      for unknown mime types instead of halting with an error (#7202).
    * Lua filters: respect Inlines/Blocks filter functions in `pandoc.walk_*`
      (Albert Krewinkel).
    * Add text as build-depend for trypandoc (#7193, Roman Beránek).
    * Bump upper-bounds for network-uri, time, attoparsec.
    * Use citeproc 0.4.
    * Use texmath 0.12.3.
    * Use jira-wiki-markup 1.3.5 (Albert Krewinkel).
    * Require latest skylighting (fixes a bug in XML syntax highlighting).
    * Use latest xml-conduit.
    * Use latest commonmark, commonmark-extensions, commonmark-pandoc.
    * Use haddock-library-1.10.0 (Albert Krewinkel).
    * Allow compilation with base 4.15 (Albert Krewinkel).
    * MANUAL:
      + Add information about `lang` and bibliography sorting.
      + Add info about YAML escape sequences, link to spec (#7152,
      Albert Krewinkel).
      + Note that `institute` variable works for HTML-based slides.
      + Update documentation on citation syntax.
      + Add citation example for locators and suffixes (Tristan Stenner)
    * Updated and fixed typos in documentation (Charanjit Singh,
      Anti-Distinctlyminty, Tatiana Porras, obcat).
    * Add instructions for installing pandoc-types before compiling filter.
    * INSTALL: add note that parallel installations should be avoided
      (#6865).
    * Remove `biblatex-nussbaum.md` test.  It is basically the same
      as `biblaetx-quotes.md`.
    * Command tests: fail if a file contains no tests---and fix a
      test that failed in that way!
* Mon Mar 22 2021 [email protected]
  - Update pandoc to version 2.13.
    [#]# pandoc 2.13 (2021-03-21)
    * Support `yaml_metadata_block` extension for `commonmark`, `gfm` (#6537).
      This supported is a bit more limited than with pandoc's
      `markdown`.  The YAML block must be the first thing in the input,
      and the leaf notes are parsed in isolation from the rest of
      the document.  So, for example, you can't use reference
      links if the references are defined later in the document.
    * Fix fallback to default partials when custom templates are used.
      If the directory containing a template does not contain the partial,
      it should be sought in the default templates, but this was not
      working properly (#7164).
    * Handle `nocite` better with `--biblatex` and `--natbib` (#4585).
      Previously the nocite metadata field was ignored with these formats.
      Now it populates a `nocite-ids` template variable and causes a
      `\nocite` command to be issued.
    * Text.Pandoc.Citeproc: apply `fixLinks` correctly (#7130).  This is code
      that incorporates a prefix like `https://doi.org/` into a following link
      when appropriate.
    * Text.Pandoc.Shared:
      + Remove `backslashEscapes`, `escapeStringUsing` [API change].  Replace
      these inefficient association list lookups with more efficient escaping
      functions in the writers that used them (for a 10-25% performance boost
      in org, haddock, rtf, texinfo writers).
      + Remove `ToString`, `ToText` typeclasses [API change].  These were needed
      for the transition from String to Text, but they are no longer used and
      may clash with other things.
      + Simplify `compactDL`.
    * Text.Pandoc.Parsing:
      + Change type of `readWithM` so that it is no longer polymorphic
      [API change].  The `ToText` class has been removed, and now that we've
      completed the transition to Text we no longer need this to operate
      on Strings.
      + Remove `F` type synonym [API change].  Muse and Org were defining their
      own `F` anyway.
    * Text.Pandoc.Readers.Metadata:
      + Export `yamlMetaBlock` [API change].
      + Make `yamlBsToMeta`, `yamlBsToRefs` polymorphic on the parser state
      [API change].
    * Markdown reader: Fix regression with `tex_math_backslash` (#7155).
    * MediaWiki reader: Allow block-level content in notes (ref) (#7145).
    * Jira reader (Albert Krewinkel):
      + Fixed parsing of autolinks (i.e., of bare URLs in the text).
      Previously an autolink would take up the rest of a line, as spaces
      were allowed characters in these items.
      + Emoji character sequences no longer cause parsing failures. This was
      due to missing backtracking when emoji parsing fails.
      + Mark divs created from panels with class "panel".
    * RST reader: fix logic for ending comments (#7134).  Previously comments
      sometimes got extended too far.
    * DocBook writer:  include Header attributes as XML attributes on
      section (Erik Rask).  Attributes with key names that are not allowed
      as XML attributes are dropped, as are attributes with invalid values
      and `xml:id` (DocBook 5) and `id` (DocBook 4).
    * Docx writer:
      + Make `nsid` in `abstractNum` deterministic.  Previously we assigned
      a random number, but we don't need random values, so now we just
      assign a value based on the list marker.
      + Use integral values for `w:tblW` (#7141).
    * Jira writer (Albert Krewinkel):
      + Block quotes are only rendered as `bq.` if they do not contain a
      linebreak.
      + Jira writer: improve div/panel handling.  Include div attributes in
      panels, always render divs with class `panel` as panels, and
      avoid nesting of panels.
    * HTML writer: Add warnings on duplicate attribute values.
      This prevents emitting invalid HTML.  Ultimately it would be good to
      prevent this in the types themselves, but this is better for now.
    * Org writer: Prevent unintended creation of ordered list items (#7132,
      Albert Krewinkel).  Adjust line wrapping if default wrapping would cause
      a line to be read as an ordered list item.
    * JATS templates: support 'equal-contrib' attrib for authors (Albert
      Krewinkel).  Authors who contributed equally to a paper may be marked
      with `equal-contrib`.
    * reveal.js template: replace JS comment with HTML (#7154, Florian Kohrt).
    * Text.Pandoc.Logging: Add `DuplicateAttribute` constructor to `LogMessage`.
      [API change]
    * Use `-j4` for linux release build.  This speeds up the build dramatically
      on arm.
    * cabal.project: remove ghcoptions.  Move flags to top level, so they can
      be set differently on the command line.
    * Require latest texmath, skylighting, citeproc, jira-wiki-markup.
      (The latest skylighting fixes a bad bug with Haskell syntax highlighting.)
      Narrow version bounds for texmath, skylighting, and citeproc, since
      the test output depend on them.
    * Use doclayout 0.3.0.2.  This significantly reduces the time and memory
      needed to compile pandoc.
    * Use `foldl'` instead of `foldl` everywhere.
    * Update bounds for random (#7156, Alexey Kuleshevich).
    * Remove uses of some partial functions.
    * Don't bake in a larger stack size for the executable.
    * Test improvements:
      + Use `getExecutablePath` from base, avoiding the dependency on
      `executable-path`.
      + Factor out `setupEnvironment` in Helpers, to avoid code duplication.
      + Fix finding of data files by setting teh `pandoc_datadir` environment
      variable when we shell out to pandoc. This avoids the need to use
      `--data-dir` for the tests, which caused problems finding `pandoc.lua`
      when compiling without the `embed_data_files` flag (#7163).
    * Benchmark improvements:
      + Build `+RTS -A8m -RTS` into default ghc-options for benchmark.
      This is necessary to get accurate benchmark results; otherwise we
      are largely measuring garbage collecting, some not related to the
      current benchmark.
      + Allow specifying BASELINE file in 'make bench' for comparison
      (otherwise the latest benchmark is chosen by default).
      + Force `readFile` in benchmarks early (Bodigrim).
    * CONTRIBUTING: suggest using a `cabal.project.local` file (#7153,
      Albert Krewinkel).
    * Add ghcid-test to Makefile.  This loads the test suite in ghcid.
* Tue Mar 09 2021 [email protected]
  - Update pandoc to version 2.12.
    Upstream has edited the change log file since the last release in
    a non-trivial way, i.e. they did more than just add a new entry
    at the top. You can review the file at:
    http://hackage.haskell.org/package/pandoc-2.12/src/changelog.md
* Sun Jan 24 2021 [email protected]
  - Update pandoc to version 2.11.4.
    [#]# pandoc 2.11.4 (2021-01-22)
    * Add `biblatex`, `bibtex` as output formats (closes #7040).
    * Recognize more extensions as markdown by default (#7034):
      `mkdn`, `mkd`, `mdwn`, `mdown`, `Rmd`.
    * Implement defaults file inheritance (#6924, David Martschenko).
      Allow defaults files to inherit options from other defaults files by
      specifying them with the following syntax:
      `defaults: [list of defaults files or single defaults file]`.
    * Fix infinite HTTP requests when writing epubs from URL source (#7013).
      Due to a bug in code added to avoid overwriting the cover image
      if it had the form `fileX.YYY`, pandoc made an endless sequence
      of HTTP requests when writing epub with input from a URL.
    * Org reader:
      + Allow multiple pipe chars in todo sequences (Albert Krewinkel, #7014).
      Additional pipe chars, used to separate "action" state from "no further
      action" states, are ignored. E.g., for the following sequence, both
      `DONE` and `FINISHED` are states with no further action required:
      `#+TODO: UNFINISHED | DONE | FINISHED`.
      + Restructure output of captioned code blocks (Albert Krewinkel, #6977).
      The Div wrapper of code blocks with captions now has the class
      "captioned-content". The caption itself is added as a Plain block
      inside a Div of class "caption". This makes it easier to write filters
      which match on captioned code blocks. Existing filters will need to be
      updated.
      + Mark verbatim code with class `verbatim` (Dimitri Sabadie, #6998).
    * LaTeX reader:
      + Handle `filecontents` environment (#7003).
      + Put contents of unknown environments in a Div when `raw_tex` is not
      enabled (#6997). (When `raw_tex` is enabled, the whole environment is
      parsed as a raw block.) The class name is the name of the environment.
      Previously, we just included the contents without the surrounding Div,
      but having a record of the environment's boundaries and name can be
      useful.
    * Mediawiki reader:
      + Allow space around storng/emph delimiters (#6993).
    * New module Text.Pandoc.Writers.BibTeX, exporting
      writeBibTeX and writeBibLaTeX. [API change]
    * LaTeX writer:
      + Revert table line height increase in 2.11.3 (#6996).
      In 2.11.3 we started adding `\addlinespace`, which produced less dense
      tables.  This wasn't an intentional change; I misunderstood a comment in
      the discussion leading up to the change. This commit restores the earlier
      default table appearance.  Note that if you want a less dense table, you
      can use something like `\def\arraystretch{1.5}` in your header.
    * EPUB writer:
      + Adjust internal links to identifiers defined in raw HTML sections
      after splitting into chapters (#7000).
      + Recognize `Format "html4"`, `Format "html5"` as raw HTML.
      + Adjust internal links to images, links, and tables after splitting into
      chapters. Previously we only did this for Div and Span and Header
      elements (see #7000).
    * Ms writer:
      + Don't justify text inside table cells.
    * JATS writer:
      + Use `<element-citation>` if `element_citations`
      extension is enabled (Albert Krewinkel).
      + Fix citations (Albert Krewinkel, #7018).  By default
      we use formatted citations.
      + Ensure that `<disp-quote>` is always wrapped in `<p>` (#7041).
    * Markdown writer:
      + Cleaned up raw formats.  We now react appropriately
      to `gfm`, `commonmark`, and `commonmark_x` as raw formats.
    * RST writer:
      + Fix bug with dropped content from inside spans with a class in
      some cases (#7039).
    * Docx writer:
      + Handle table header using styles (#7008).  Instead of hard-coding
      the border and header cell vertical alignment, we now let this
      be determined by the Table style, making use of Word's
      "conditional formatting" for the table's first row.  For
      headerless tables, we use the tblLook element to tell Word
      not to apply conditional first-row formatting.
    * Commonmark writer:
      + Implement start number on ordered lists (#7009).  Previously they always
      started at 1, but according to the spec the start number is respected.
    * HTML writer:
      + Fix implicit_figure at end of footnotes (#7006).
    * ConTeXt template: Remove `\setupthinrules` from default template.
      The width parameter this used is not actually supported,
      and the command didn't do anything.
    * Text.Pandoc.Extensions:
      + Add `Ext_element_citations` constructor (Albert Krewinkel).
    * Text.Pandoc.Citeproc.BibTeX: New unexported function
      `writeBibtexString`.
    * Text.Pandoc.Citeproc:
      + Use finer grained imports (Albert Krewinkel).
      + Factor out and export `getStyle` [API change].
      + Export `getReferences` [API change, #7106].
      + Factor out getLang.
    * Text.Pandoc.Parsing: modify `gridTableWith'` for headerless tables.
      If the table lacks a header, the header row should be an empty
      list. Previously we got a list of empty cells, which caused
      an empty header to be emitted instead of no header.  In LaTeX/PDF
      output that meant we got a double top line with space between.
    * ImageSize:  use `viewBox` for SVG if no length, width attributes (#7045).
      This change allows pandoc to extract size information from more SVGs.
    * Add simple default.nix.
    * Use commonmark 0.1.1.3.
    * Use citeproc 0.3.0.5.
    * Update default CSL to use latest chicago-author-date.csl.
    * CONTRIBUTING.md: add note on GNU xargs.
    * MANUAL.txt:
      + Update description of `-L`/`--lua-filter`.
      + Document use of citations in note styles (#6828).
* Wed Dec 30 2020 [email protected]
  - Update pandoc to version 2.11.3.2.
    [#]# pandoc 2.11.3.2 (2020-12-29)
    * HTML reader: use renderTags' from Text.Pandoc.Shared (Albert Krewinkel).
      A side effect of this change is that empty `<col>` elements are written
      as self-closing tags in raw HTML blocks.
    * Asciidoc writer: Add support for writing nested tables (#6972, timo-a).
      Asciidoc supports one level of nesting. If deeper tables are to be
      written, they are omitted and a warning is issued.
    * Docx writer: fix nested tables with captions (#6983).
      Previously we got unreadable content, because docx seems
      to want a `<w:p>` element (even an empty one) at the end of
      every table cell.
    * Powerpoint writer: allow arbitrary OOXML in raw inline elements
      (Albert Krewinkel).  The raw text is now included verbatim in the
      output. Previously is was parsed into XML elements, which prevented
      the inclusion of partial XML snippets.
    * LaTeX writer: support colspans and rowspans in tables (#6950,
      Albert Krewinkel).  Note that the multirow package is needed for
      rowspans.  It is included in the latex template under a variable,
      so that it won't be used unless needed for a table.
    * HTML writer: don't include p tags in CSL bibliography entries
      (#6966).  Fixes a regression in 2.11.3.
    * Add `meta-description` variable to HTML templates (#6982). This
      is populated by the writer by stringifying the `description`
      field of metadata (Jerry Sky).  The `description` meta tag will
      make the generated HTML documents more complete and SEO-friendly.
    * Citeproc: fix handling of empty URL variables (`DOI`, etc.).
      The `linkifyVariables` function was changing these to links
      which then got treated as non-empty by citeproc, leading
      to wrong results (e.g. ignoring nonempty URL when empty DOI is present).
      See jgm/citeproc#41.
    * Use citeproc 0.3.0.3.  Fixes an issue in author-only citations when
      both an author and translator are present, and an issue with
      citation group delimiters.
    * Require texmath 0.12.1.  This improves siunitx support in math,
      fixes bugs with `\*mod` family operators and arrays, and avoids
      italicizing symbols and operator names in docx output.
    * Ensure that the perl interpreter used for filters with `.pl`
      extension (wuffi).
    * MANUAL: note that textarea content is never parsed as Markdown
      (Albert Krewinkel).
* Sat Dec 19 2020 [email protected]
  - Update pandoc to version 2.11.3.1.
    [#]# pandoc 2.11.3.1 (2020-12-18)
    * Added some missing files to extra-source-files and data
      files, so they are included in the sdist tarball.  Closes #6961.
      Cleaned up some extraneous data and test files, and added
      a CI check to ensure that the test and data files included
      in the sdist match what is in the git repository.
    * Use citeproc 0.3.0.1, which avoids removing nonbreaking
      space at the end of the `initialize-with` attribute. (Some
      journals require nonbreaking space after initials, and this
      makes that possible.)
* Fri Dec 18 2020 [email protected]
  - Update pandoc to version 2.11.3.
    [#]# pandoc 2.11.3 (2020-12-17)
    * With `--bibliography` (or `bibliography` in metadata), a
      URL may now be provided, and pandoc will fetch the resource.
      In addition, if a file path is provided and it is not
      found relative to the working directory, the resource
      path will be searched (#6940).
    * Add `sourcepos` extension for `commonmark`, `gfm`, `commonmark_x`
      (#4565).  With the `sourcepos` extension set set, `data-pos`
      attributes are added to the AST by the commonmark reader. No other
      readers are affected.  The `data-pos` attributes are put on elements
      that accept attributes; for other elements, an enlosing Div or Span
      is added to hold the attributes.
    * Change extensions for `commonmark_x`: replace `auto_identifiers`
      with `gfm_auto_identifiers` (#6863).  `commonmark_x` never actually
      supported `auto_identifiers` (it didn't do anything), because the
      underlying library implements gfm-style identifiers only.  Attempts
      to add the `auto_identifiers` extension to `commonmark` will now
      fail with an error.
    * HTML reader:
      + Split module into several submodules (Albert Krewinkel).  Reducing
      module size should reduce memory use during compilation.
      + Support advanced table features (Albert Krewinkel):
      block level content in captions, row and colspans,
      body headers, row head columns, footers, attributes.
      + Disable round-trip testing for tables. Information for cell
      alignment in a column is not preserved during round-trips (Albert
      Krewinkel).
      + Allow finer grained options for tag omission (Albert Krewinkel).
      + Simplify list attribute handling (Albert Krewinkel).
      + Pay attention to `lang` attributes on body element (#6938).
      These (as well as `lang` attributes on the html element) should update
      lang in metadata.
      + Retain attribute prefixes and avoid duplicates (#6938).
      Previously we stripped attribute prefixes, reading `xml:lang` as
      `lang` for example. This resulted in two duplicate `lang`
      attributes when `xml:lang` and `lang` were both used.  This commit
      causes the prefixes to be retained, and also avoids invald
      duplicate attributes.
    * Commonmark reader:
      + Refactor `specFor`.
      + Set input name to `""` to avoid clutter in sourcepos output.
    * Org reader:
      + Parse `#+LANGUAGE` into `lang` metadata field (#6845, Albert
      Krewinkel).
      + Preserve targets of spurious links (#6916, Albert
      Krewinkel).  Links with (internal) targets that the reader doesn't
      know about are converted into emphasized text. Information on the
      link target is now preserved by wrapping the text in a Span of class
      `spurious-link`, with an attribute `target` set to the link's
      original target. This allows to recover and fix broken or unknown
      links with filters.
    * DocBook reader:
      + Table text width support (#6791, Nils Carlson).
      Table width in relation to text width is not natively supported
      by docbook but is by the docbook `fo` stylesheets through an XML
      processing instruction, `<?dbfo table-width="50%"?>`.
    * LaTeX reader:
      + Improve parsing of command options (#6869, #6873).
      In cases where we run into trouble parsing inlines til the
      closing `]`, e.g. quotes, we return a plain string with the
      option contents. Previously we mistakenly included the brackets
      in this string.
      + Preserve center environment (#6852, Igor Pashev).
      The contents of the `center` environment are put in a `Div`
      with class `center`.
      + Don't parse `\rule` with width 0 as horizontal rule. These are
      sometimes used as spacers in LaTeX.
      + Don't apply theorem default styling to a figure inside (#6925).
      If we put an image in italics, then when rendering to Markdown
      we no longer get an implicit figure.
    * Dokuwiki reader:
      + Handle unknown interwiki links better (#6932).
      DokuWiki lets the user define his own Interwiki links.  Previously
      pandoc reacted to these by emitting a google search link, which is
      not helpful. Instead, we now just emit the full URL including the
      wikilink prefix, e.g. `faquk>FAQ-mathml`.  This at least gives users
      the ability to modify the links using filters.
    * Markdown writer:
      + Properly handle boolean values in writing YAML metadata (#6388).
      + Ensure that a new csl-block begins on a new line (#6921).
      This just looks better and doesn't affect the semantics.
    * RST writer:
      + Better image handling (#6948).  An image alone in its paragraph
      (but not a figure) is now rendered as an independent image, with an
      `alt` attribute if a description is supplied.  An inline image that
      is not alone in its paragraph will be rendered, as before, using a
      substitution.  Such an image cannot have a "center", "left", or
      "right" alignment, so the classes `align-center`, `align-left`, or
      `align-right` are ignored.  However, `align-top`, `align-middle`,
      `align-bottom` will generate a corresponding `align` attribute.
    * Docx writer:
      + Keep raw openxml strings verbatim  (#6933, Albert Krewinkel).
      + Use Content instead of Element.  This allows us to inject
      raw OpenXML into the document without reparsing it into an
      Element, which is necessary if you want to inject an open
      tag or close tag.
      + Fix bullets/lists indentation, so that the first level is slightly
      indented to the right instead of right on the margin (cholonam).
      + Support bold and italic in "complex script" (#6911).
      Previously bold and italics didn't work properly in LTR
      text.  This commit causes the w:bCs and w:iCs attributes
      to be used, in addition to w:b and w:i, for bold and
      italics respectively.
    * ICML writer:
      + Fix image bounding box for custom widths/heighta (Mauro Bieg, #6936).
    * LaTeX writer:
      + Improve table spacing (#6842, #6860).
      Remove the `\strut` that was added at the end of minipage
      environments in cells.  Replace `\tabularnewline` with
      `\\ \addlinespace`.
      + Improve calculation of column spacing (#6883).
      + Extract table handling into separate module (Albert Krewinkel).
      + Fix bug with nested `csl-` display Spans (#6921).
      + Improve longtable output (#6883).  Don't create minipages for
      regular paragraphs.  Put width and alignment information in the
      longtable column descriptors.
    * OpenDocument writer:
      + Support for table width as a percentage of text width
      (#6792, Nils Carson).
      + Implement Div and Span ident support (#6755, Nils Carson).
      Spans and Divs containing an ident in the Attr will become bookmarks
      or sections with idents in OpenDocument format.
      + Add two extensions, `xrefs_name` and `xrefs_number` (#6774, Nils
      Carlson).  Links to headings, figures and tables inside the
      document are substituted with cross-references that will use the
      name or caption of the referenced item for `xrefs_name` or the
      number for `xrefs_number`.  For the `xrefs_number` to be useful
      heading numbers must be enabled in the generated document and
      table and figure captions must be enabled using for example the
      `native_numbering` extension.  In order for numbers and reference
      text to be updated the generated document must be refreshed.
    * JATS writer:
      + Support advanced table features (Albert Krewinkel).
      + Support author affiliations (#6687, Albert Krewinkel).
    * Docbook writer:
      + Use correct id attribute consistently (Jan Tojnar).
      DocBook5 should always use `xml:id` instead of `id`.
      + Handle admonition titles better (Jan Tojnar).
      Docbook reader produces a `Div` with `title` class for `<title>`
      element within an “admonition” element. Markdown writer then turns
      this into a fenced div with `title` class attribute. Since fenced
      divs are block elements, their content is recognized as a
      paragraph by the Markdown reader. This is an issue for Docbook
      writer because it would produce an invalid DocBook document from
      such AST – the `<title>` element can only contain “inline”
      elements.  Handle this special case separately by unwrapping
      the paragraph before creating the `<title>` element.
      + Add XML namespaces to top-level elements (#6923, Jan Tojnar).
      Previously, we only added `xmlns` attributes to chapter
      elements, even when running with `--top-level-division=section`.
      These namespaces are now added to part and section elements too,
      when they are the selected top-level divisions.
      We do not need to add namespaces to documents produced with
      `--standalone` flag, since those will already have xmlns attribute on
      the root element in the template.
    * HTML writer:
      + Fix handling of nested `csl-` display spans (#6921).
      Previously inner Spans used to represent CSL display attributes were
      not rendered as div tags as intended.
    * EPUB writer:
      + Include title page in landmarks (#6919).
      Note that the toc is also included if `--toc` is specified.
      + Add frontmatter type on body element for nav.xhtml (#6918).
    * EPUB templates: use preserveAspectRatio="xMidYMid" for cover image (#6895,
      Shin Sang-jae).  This change affects both the epub2 and the epub3
      templates.  It avoids distortion of the cover image by requiring that the
      aspect ratio be preserved.
    * LaTeX template:
      + Include `csquotes` package if `csquotes` variable set.
      + Put back `amssymb`.  We need it for checkboxes in todo lists,
      and maybe for other things.  In this location it seems compatible
      with the cases that prompted #6469 and PR #6762.
      + Disable language-specific shorthands in babel (#6817, #6887).
      Babel defines "shorthands" for some languages, and these can
      produce unexpected results. For example, in Spanish, `1.22`
      gets rendered as `122`, and `et~al.` as `etal`.
      One would think that babel's `shorthands=off` option (which
      we were using) would disable these, but it doesn't.  So we
      remove `shorthands=off` and add some code that redefines
      the shorthands macro.  Eventually this will be fixed in babel,
      I hope, and we can revert to something simpler.
    * JATS template: allow array of persistent institute ids in `pid`
      (Albert Krewinkel).
    * Text.Pandoc.Parsing:  minor code and efficiency improvements.
    * Text.Pandoc.Extension:
      + Add `Ext_sourcepos` constructor for `Extension` [API change].
      + Add `Ext_xrefs_name` and `Ext_xrefs_number` constructors for
      `Extension` (Nils Carson) [API change].
    * Text.Pandoc.Citeproc:
      + Fix truncation of `[Citation]` list in `Cite` inside footnotes (#6890).
      This affected author-in-text citations in footnotes.  It didn't cause
      problems for the printed output, but for filters that expected the
      citation id and other information.
      + Allow the use of both inline and external references (#6951),
      as with pandoc-citeproc.  References defined in the document's
      metadata take priority over references with the same id defined in
      an external bibliography.
      + Use `fetchItem` to get external bibliography (#6940).
      + Ensure that BCP47 lang codes can be used.  We ignore the variants
      and just use the base lang code and country code when passing off
      to citeproc.
      + Citeproc BibTeX parser: revert change in `getRawField`
      which was made (for reasons forgotten) when transferring
      this code from pandoc-citeproc.  The change led to `--` in
      URLs being interpreted as en-dashes, which is unwanted (#6874).
    * Text.Pandoc.ImageSize:
      + Default to DPI 72 if the format specifies DPI of 0 (#6880).
      This shouldn't happen, in general, but it can happen with
      JPEGs that don't conform to the spec.  Having a DPI of 0
      will blow up size calculations (division by 0).
      + ImageSize: use JuicyPixels to determine size for png, jpeg, and
      gif, instead of doing our own binary parsing (#6936). This
      gives more reliable results.
    * Text.Pandoc.CSS:
      + Remove `foldOrElse` (internal module) (Albert Krewinkel).
    * Use skylighting 0.10.2 (#6625).
    * Use citeproc 0.3. This fixes issues with references with
      duplicate ids (jgm/citeproc#36).
    * Use doctemplates 0.9.  This fixes issues with boolean
      metadata values in the Markdown writer (#6388)
      and in `meta-json` (#6650).  It also fixes
      issues with nested for loops in templates.
    * Add translations zh-Hans.yaml and zh-Hant.yaml (#6904, #6909,
      Kolen Cheung, taotieren).
    * Add tests: True to cabal.project.
      This fixes some CI failures for cabal.
    * Normalize test/tables/*.native (#6888, Kolen Cheung).
    * Move executable to `app` directory to avoid problems with cabal repl.
    * CONTRIBUTING: add section "How can I help?" (#6892, Albert Krewinkel).
      Also adds a paragraph aimed at highlighting the importance of feature
      maintenance.
    * MANUAL: Document that --number-sections works in `ms` (#6935).
* Thu Dec 17 2020 [email protected]
  - disable %{ix86} build
* Fri Nov 20 2020 [email protected]
  - Update pandoc to version 2.11.2.
    [#]# pandoc 2.11.2 (2020-11-19)
    * Default to using ATX (`##`-style) headings for Markdown output
      (#6662, Aner Lucero).  Previously we used Setext (underlined) headings
      by default for levels 1--2.
    * Add option `--markdown-headings=atx|setext`, and deprecate
      `--atx-headers` (#6662, Aner Lucero).
    * Support `markdown-headings` in defaults files.
    * Fix corner case in YAML metadata parsing (#6823).  Previously YAML
      metadata would sometimes not get recognized if a field ended with a
      newline followed by spaces.
    * `--self-contained`: increase coverage (#6854).
      Previously we only self-contained attributes for certain tag names
      (`img`, `embed`, `video`, `input`, `audio`, `source`, `track`,
      `section`).  Now we self-contain any occurrence of `src`,
      `data-src`, `poster`, or `data-background-image`, on any tag; and
      also `href` on `link` tags.
    * Markdown reader:
      + Fix detection of locators following in-text citations.
      Prevously, if we had `@foo [p. 33; @bar]`, the `p. 33` would be
      incorrectly parsed as a prefix of `@bar` rather than a suffix of
      `@foo`.
      + Improve period suppression algorithm for citations in notes
      in note citation styles (#6835).
      + Don't increment `stateNoteNumber` for example list references.
      This helps with #6836 (a bug in which example list references
      disturb calculation of citation note number and affect when
      `ibid` is triggered).
    * LaTeX reader:
      + Move `getNextNumber` from Readers.LaTeX to Readers.LaTeX.Parsing.
      + Fix negative numbers in siunitx commands.  A change in pandoc 2.11
      broke negative numbers, e.g.  `\SI{-33}{\celcius}` or `\num{-3}`.
      This fixes the regression.
    * DocBook reader: drop period in formalpara title
      and put it in a div with class `formalpara-title`, so that
      people can reformat with filters (#6562).
    * Man reader: improve handling of `.IP` (#6858).  We now better handle
      `.IP` when it is used with non-bullet, non-numbered lists, creating a
      definition list.  We also skip blank lines like groff itself.
    * Bibtex reader: fall back on `en-US` if locale for LANG not found.
      This reproduces earlier pandoc-citeproc behavior (jgm/citeproc#26).
    * JATS writer:
      + Wrap all tables (Albert Krewinkel).
      All `<table>` elements are put inside `<table-wrap>` elements, as the
      former are not valid as immediate child elements of `<body>`.
      + Move Table handling to separate module (Albert Krewinkel).
      Adds two new unexported modules:
      Text.Pandoc.Writers.JATS.Types, Text.Pandoc.Writers.JATS.Table.
    * Org writer:
      + Replace org #+KEYWORDS with #+keywords (TEC).
      As of ~2 years ago, lower case keywords became the standard (though
      they are handled case insensitive, as always).
      + Update org supported languages and identifiers according to the
      current list contained in
      <https://orgmode.org/worg/org-contrib/babel/languages/index.html>
      (TEC).
    * Only use `filterIpynbOutput` if input format is ipynb (#6841).
      Before this change content could go missing from divs with class
      `output`, even when non-ipynb was being converted.
    * When checking reader/writer name, check base name now that we permit
      extensions on formats other than markdown.
    * Text.Pandoc.PDF: Fix `changePathSeparators` for Windows (#6173).
      Previously a path beginning with a drive, like `C:\foo\bar`, was
      translated to `C:\/foo/bar`, which caused problems.
      With this fix, the backslashes are removed.
    * Text.Pandoc.Logging: Add constructor `ATXHeadingInLHS` constructor
      to `LogMessage` [API change].
    * Fix error that is given when people specify `doc` output (#6834,
      gison93).
    * LaTeX template:  add a `\break` after parbox in `CSLRightInline`.
      This should fix spacing problems between entries with numeric styles.
      Also fix number of params on `CSLReferences`.
    * reveal.js template: Put quotes around `controlsLayout`,
      `controlsBackArrows`, and `display`, since these require strings.
      Add `showSlideNumber`, `hashOneBasedIndex`, `pause`.
    * Use citeproc 0.2.  This fixes a bug with title case around parentheses.
    * pandoc.cabal: remove 'static' flag.
      This isn't really necessary and can be misleading (e.g. on macOS,
      where a fully static build isn't possible). cabal's new option
      `--enable-executable-static` does the same. On stack you can add
      something like this to the options for your executable in package.yaml:
      ld-options: -static -pthread
    * Remove obsolete bibutils flag setting in `linux/make_artifacts.sh`.
    * Manual:
      + Correct `link-citation` -> `link-citations`.
      + Add a sentence about `pagetitle` for HTML (#6843, Alex Toldaiev).
    * INSTALL.md: Remove references to `pandoc-citeproc` (#6857).
    * CONTRIBUTING: describe hlint and how it's used (#6840, Albert
      Krewinkel).
* Sun Nov 08 2020 [email protected]
  - Update pandoc to version 2.11.1.1.
    [#]# pandoc 2.11.1.1 (2020-11-07)
    * Citeproc: improve punctuation in in-text note citations (#6813).
      Previously in-text note citations inside a footnote would sometimes have
      the final period stripped, even if it was needed (e.g. on the end of
      'ibid').
    * Use citeproc 0.1.1.1.  This improves the decision about when
      to use `ibid` in cases where citations are used inside
      a footnote (#6813).
    * Support `nocase` spans for `csljson` output.
    * Require latest commonmark, commonmark-extensions.
      This fixes a bug with `autolink_bare_uris` and commonmark.
    * LaTeX reader: better handling of `\\` inside math in table cells (#6811).
    * DokuWiki writer:  translate language names for code elements
      and improve whitespace (#6807).
    * MediaWiki writer: use `syntaxhighlight` tag instead of deprecated
      `source` for highlighted code (#6810).  Also support `startFrom`
      attribute and `numberLines`.
    * Lint code in PRs and when committing to master (#6790,
      Albert Krewinkel).
    * doc/filters.md: describe technical details of filter invocations (#6815,
      Albert Krewinkel).
* Sat Nov 07 2020 [email protected]
  - Update pandoc to version 2.11.1.
    [#]# pandoc 2.11.1 (2020-11-03)
    * DocBook Reader: fix duplicate bibliography bug (#6773, Nils Carlson).
    * HTML reader:
      + Parse contents of iframes (#6770).
      + Parse inline svg as image unless `raw_html` is set in the reader (in
      which case the svg is passed through as raw HTML) (#6770).
    * LaTeX reader:
      + Fix bug parsing macro arguments (#6796).  If `\cL` is
      defined as `\mathcal{L}`, and `\til` as `\tilde{#1}`, then
      `\til\cL` should expand to `\tilde{\mathcal{L}}`, but
      pandoc was expanding it to `\tilde\mathcal{L}`.  This is
      fixed by parsing the arguments in "verbatim mode" when the
      macro expands arguments at the point of use.
      + Properly support optional (cite) argument for
      `\blockquote` from `csquotes` (#6802).
    * LaTeX writer: Improved calculation of table column widths.
      We now have LaTeX do the calculation, using `\tabcolsep`.
      So we should now have accurate relative column widths no
      matter what the text width.  The default template has been modified to load
      the calc package if tables are used.
    * HTML writer: Fix duplicate "class" attribute for table
      rows (Andy Morris).
    * Text.Pandoc.Filter: allow shorter YAML representation of Citeproc
      (Albert Krewinkel).  The map-based YAML representation of filters expects
      `type` and `path` fields. The path field had to be present for all filter
      types, but is not used for citeproc filters. The field can now be omitted
      when type is "citeproc", as described in the MANUAL.
    * Text.Pandoc.Error: Add `PandocBibliographyError` constructor
      for `PandocError` [API change].  This ensures that bibliography parsing
      errors generate messages that include the bibliography file name --
      otherwise it can be quite mysterious where it is coming from.
    * Citeproc: properly handle `csl` field with `data:` URI (#6783).
      This is used with the JATS writer, so this fixes a regression
      in pandoc 2.11 with JATS output and citeproc.
    * Allow `citation-abbreviations` in defaults file.
    * JATS templates: ensure `jats_publishing` output is valid
      (Albert Krewinkel).
    * LaTeX template:  Fix `CSLRightInline`, so that it does not
      run over the right margin.
    * HTML template: default CSS tweaks (Mauro Bieg and John
      MacFarlane).
    - Fix margin before codeblock
    - Add `monobackgroundcolor` variable, making the background color
      and padding of code optional.
    - Ensure that backgrounds from highlighting styles take precedence over
      monobackgroundcolor
    - Remove list markers from TOC
    - Add margin-bottom where needed
    - Remove italics from blockquote styling
    - Change borders and spacing in tables to be more consistent with other
      output formats
    - Style h5, h6
    - Set font-size for print media to 12pt.
    - Reduce interline space.
    - Reduce interparagraph space.
    - Reduce line width.
    - Remove the special `line-height: 1` for table cells.
    - Remove the special line-height for pre.
    - Ensure that there is a bit more space before a heading
      than after.
    - Slightly reduced space after title header.
    - Add CSS example to MANUAL
    * man template:  Change comment that triggers `tbl` from
      `.\"t` to `'\" t`, as specified in groff_man(7) (#6803).
    * Use latest commonmark, commonmark-extensions.
      This fixes a bug with nested blocks in footnotes with the
      `footnote` extension to `commonmark`.  See jgm/commonmark-hs#63.
    * Citeproc: use comma for in-text citations inside footnotes.
      When an author-in-text citation like `@foo` occurs in a footnote,
      we now render it with:  `AUTHOR NAME + COMMA + SPACE + REST`.
      Previously we rendered: `AUTHOR NAME + SPACE + "(" + REST + ")"`.
      This gives better results.  Note that normal citations are still
      rendered in parentheses.
    * Use latest citeproc:
      + citeproc no longer capitalizes notes, so we do it
      in pandoc when appropriate.
      + Closes #6783.
    * Clarify manual on `--track-changes` (#6801).
    * Add `doc/jats.md` to document pandoc's handling of JATS
      (#6794, Albert Krewinkel).
    * Fix code example in lua-filters.md (#6795).
* Fri Oct 23 2020 [email protected]
  - Update pandoc to version 2.11.0.4.
    [#]# pandoc 2.11.0.4 (2020-10-21)
    * Commonmark writer: fix regression with fenced divs (#6768).
      Starting with 2.10.1, fenced divs no longer render with
      HTML div tags in commonmark output.  This is a regression
      due to our transition from cmark-gfm.  This commit fixes it.
    * Use released version of citeproc.  (This fixes a mis-step
      in the 2.11.0.3 release, which is now deprecated.)
    * Use latest sylighting, with support for `groovy`.
    * Document that --html-q-tags requires the smart extension on the reader
      (#6766).
    [#]# pandoc 2.11.0.3 (2020-10-20)
    * Use latest citeproc (closes #6765). This fixes a problem with
      author-in-text citations for references including both an author
      and an editor. Previously, both were included in the text, but only
      the author should be.
    * With `--citeproc`, ensure that the final period is removed when
      citations that occur in notes in note-based styles get put in
      parentheses.  See jgm/citeproc#20.
    * Normalize rewritten image paths with `--extract-media` (#6761).
      This change will avoid mixed paths like this one when
      `--extract-media` is used with a Word file:
      `![](C:\Git\TIJ4\Markdown/media/image30.wmf)`.  Instead we'll get
      `![](C:\Git\TIJ4\Markdown`media`image30.wmf)`.
    * Modify `--version` output.  Use space more efficiently and report the
      citeproc and ipynb versions, along with skylighting, texmath, and
      pandoc-types.  Drop the word "default" before "user data directory."
    * DocBook reader: bibliomisc and anchor support (#6754, Nils Carlson).
      Also ensure that bibliodiv without a title no longer results in
      an empty Header.
    * ConTeXt template: adds `\setupinterlinespace` to fonts larger
      than normal (#6763, Denis Maier).
    * LaTeX template: Do not load amssymb if not needed (#6469, Angelo Peronio).
      See <https://tex.stackexchange.com/a/549938>.
    * Relax upper bound on hslua, allow hslua-1.3.* (Albert Krewinkel).
    * MANUAL:
      + Improve explanation of "indent" variable (#6767, Cyrus Yip).
      + Remove org from list of input formats supporting raw_tex (#6753,
      Nick Fleisher).

  - Update pandoc to version 2.11.
    [#]# pandoc 2.11 (2020-10-11)
    * Add `--citeproc` (`-C`) option to trigger built-in citation processing.
      It is no longer necessary to use the external `pandoc-citeproc`
      filter.  `--citeproc` behaves like a filter and can be positioned
      relative to other filters as they appear on the command line.
      The new built-in citation processing uses the citeproc library,
      a reimplementation of CSL citation processing that fixes many
      of the shortcomings of pandoc-citeproc.  In general, citation
      processing should work much the same as it did with pandoc-citeproc,
      but with greater fidelity to CSL styles and better performance.
      (The tests from the pandoc-citeproc package have been carried
      over to pandoc.) The following differences should be noted:
    - At this point, only some of the writers (HTML, ms, LaTeX) properly
      interpret CSL display styles.  You should get decent output in
      all formats (at least as good as with pandoc-citeproc), but
      indentation and block-alignment may not be right.
    - pandoc-citeproc searches the `~/.csl` directory for `.csl`
      styles.  Pandoc instead searches the `csl` subdirectory of
      the pandoc user data directory (e.g., `~/.pandoc/csl` or
      `~/.local/share/pandoc/csl`).  Users who already keep
      CSL styles in `~/.csl` may find it convenient to add a
      symlink.
    - Some of the bibliography formats supported by pandoc-citeproc (via
      hs-bibutils) are no longer supported:  Copac, EndNote,
      ISI, MEDLINE, MODS, and RIS.  If you use one of these formats,
      you may use the `bibutils` utility to convert to BibLaTeX.
      We now support only BibTeX, BibLaTeX, CSL JSON,
      and pandoc's YAML/Markdown analogue of CSL JSON.
    - pandoc-citeproc would always retrieve the independent parent
      of a dependent style by doing an HTTP request.  pandoc will
      now first seek the independent parent locally (in the resource
      path or in the `csl` subdirectory of the pandoc user data
      directory) before resorting to HTTP.  In addition, you may
      omit the `.csl` extension, e.g. `--csl zoology`.
    - Using the `--bibliography` option (or including
      `bibliography` in YAML metadata) no longer triggers
      citation processing implicitly: one must always use the
      `--citeproc` option if citation processing is wanted.
    * Add `csljson` as and input and output format. This allows pandoc
      to convert between `csljson` and other bibliography formats
      (e.g. `-f csljson -t markdown -s` or `-f bibtex -t csljson`),
      and to generate formatted versions of CSL JSON bibliographies
      (e.g., `pandoc -f csljson --citeproc pl.json -o pl.pdf`).
    * Added `bibtex`, `biblatex` as input formats.  This allows pandoc
      to convert between BibLaTeX and BibTeX and other bibliography formats,
      and to generated formatted versions of BibTeX/BibLaTeX bibliographies
      (e.g., `pandoc -f biblatex --citeproc pl.bib -o pl.pdf`).
    * Raise informative errors when YAML metadata parsing fails (#6730).
      Previously the command would succeed, returning empty metadata,
      with no errors or warnings.
    * Sort languages in `--list-highlight-languages` output (#6718,
      Albert Krewinkel).  Languages were previously sorted by their
      long name, which leads to unexpected results).
    * Add CSS to default HTML template (#6601, Mauro Bieg).  This
      greatly improves the default typography in pandoc's HTML
      output.  The CSS is sensitive to a number of variables
      (e.g. `mainfont`, `fontsize`, `linestretch`): see the manual for
      details. To restore the earlier, more spartan output, you can
      disable this with `-M document-css=false`.
    * Support `--toc-depth` option for ODT writer (#6696, niszet).
    * Fix issues with Windows UNC paths with some options (#5127).
    * Remove `fenced_code_blocks` and `backtick_code_blocks` from allowed
      `commonmark` and `gfm` extensions.  These shouldn't really be counted
      as extensions, because they can't be disabled in commonmark.
      Adjust markdown writer to check for the commonmark variant in addition
      to extensions.
    * Add these extensions to `gfm` and `commonmark`:
      `fenced_code_blocks`, `backtick_code_blocks`, `fenced_code_attributes`.
      These can't really be disabled in the reader, but they need to be enabled
      in the writer or we just get indented code.
    * Make sure proper set of extensions is recognized for `commonmark_x`.
    * Allow `gfm_auto_identifiers`, `ascii_identifiers` extensions for `docx`.
    * Markdown reader:
      + Add `Maybe FilePath` parameter to `yamlToMeta` [API change].
      + Export `yamlToRefs` [API change], a version of `yamlToMeta`
      specialized to references.
      + Set `citationNoteNum` accurately in citations.
      + Revise abbreviation support.  Don't insert a nonbreaking space after a
      potential abbreviation if it comes right before a note or citation.
      This causes problems for citeproc's moving of note citations.
    * LaTeX reader:
      + Support missing siunitx commands (#6658).
      + Support `squared`, `cubed`, `tothe` in siunitx (#6657).
      + Improved uncertainty handling in slunitx.
      + Factored out siunitx stuff into separate unexposed module.
      + Fix improper empty cell filtering (#6689, Christian Despres).
      + Fix parsing of "show name" in `\newtheorem` (#6734).
      Previously we were just treating it as a string and
      ignoring  accents and formatting.
      + Prevent wrong nesting of `\multirow` and `\multicolumn` table
      cells (#6603, Laurent P. René de Cotret).
      + Table cell parser not consuming spaces correctly (#6596,
      Laurent P. René de Cotret).
      + Change `SIRange` to `SIrange` (#6617, Emerson Harkin).
      + Allow blank lines inside `\author` (#6324).
    * DocBook reader:
      + Don't squelch space at end of emphasis and other inline elements;
      instead, move it outside the element (#6719).
      + Implement table cell alignment (#6698, Nils Carlson).
      + Implement column span support for tables (#6492, Nils Carlson).
      + Update list of block level tags (#6610).
    * JATS reader:
      + Don't squelch space at end of emphasis and other inline elements;
      instead, move it outside the element (#6719).
    * RST reader:
      + Apply `.. class::` directly to following Header rather than creating
      a surrounding Div (#6699).
    * Docx reader:
      + Allow empty dates in comments and tracked changes (#6726, Diego
      Balseiro).
    * Markdown writer:
      + Be less aggressive about using quotes for YAML values,
      allowing e.g. a quotation mark or bracket as long as it's not at the
      beginning of the line.
      + Use double quotes for YAML metadata (#6727).
      + Sort YAML metadata keys in Markdown output case-insensitive.
    * Asciidoc writer:
      + Support asciidoctor's block figures (#6538, argent0).
    * LaTeX writer:
      + Fix spacing issue with list in definition list.
      When a list occurs at the beginning of a definition list definition,
      it can start on the same line as the label, which looks bad.
      Fix that by starting such lists with an `\item[]`.
    * HTML writer:
      + Support intermediate table headers (#5314, Albert Krewinkel).
      + Support attributes on all table elements (Albert Krewinkel).
      + Render table footers if present (#6314, Albert Krewinkel).
      + Fix addition of `doc-biblioentry` role.
      + Support colspans and rowspans in HTML tables (#6312, Albert Krewinkel).
    * ICML writer:
      + Support internal document links (#5541, Leonard Rosenthol).
      + Changed default link state to invisible (#6676, Leonard Rosenthol).
    * Docx writer:
      + Better handle list items whose contents are lists (#5948, Michael
      Hoffmann).  If the first element of a bulleted or ordered list is
      another list, then that first item would previously disappear if the
      target format is docx.
      + Separate adjacent tables (#4315).  Word combines adjacent tables,
      so to prevent this we insert an empty paragraph between two
      adjacent tables.
    * Org writer:
      + Don't force blank line after headings (#6554).
    * OpenDocument writer:
      + Implement table cell alignment (#6700 Nils Carson, Mauro Bieg).
      + New table cell support with row and column spans (#6682, Nils Carson).
      + Syntax highlighting for inline code (#6711, niszet).
    * Add Text.Pandoc.Citeproc module, exporting `processCitations`
      [API change].  This depends on several other, unexported
      modules under Text.Pandoc.Citeproc.
    * Add module Text.Pandoc.Writers.CslJson, exporting `writeCslJson`.
      [API change]
    * Add module Text.Pandoc.Readers.CslJson, exporting `readCslJson`.
      [API change]
    * Add module Text.Pandoc.Readers.BibTeX, exporting `readBibTeX` and
      `readBibLaTeX`. [API change]
    * Text.Pandoc.Filter: Add `CiteprocFilter` constructor to Filter.
      [API change] This runs the processCitations transformation.
      We need to treat it like a filter so it can be placed
      in the sequence of filter runs (after some, before others).
      In FromYAML, this is parsed from `citeproc` or `{type: citeproc}`,
      so this special filter may be specified either way in a defaults file
      (or by `citeproc: true`, though this gives no control of positioning
      relative to other filters).
    * Add new exported module Text.Pandoc.Writers.AnnotatedTable [API change]
      (#6655, Christian Despres).  This module (which should generally
      be imported qualified to avoid name conflicts) provides a
      `Table` type that mirrors the structure of a pandoc `Table`,
      but with added inferred information so that the writers do not have to
      lay out tables themselves. The `toTable` and `fromTable` functions convert
      between an annotated `Table` and a regular pandoc `Table`. In addition to
      producing a `Table` with coherent and well-formed annotations, the
      `toTable` function also normalizes its input table like the table
      builder does.  Tests ensure that `toTable` normalizes tables exactly
      like the table builder, and that its annotations are coherent.
    * Text.Pandoc.Logging:
      + Remove unused `CouldNotParseYamlMetadata` constructor for `LogMessage`
      [API change].
      + Add `CiteprocWarning` constructor to `LogMessage` [API change].
    * Text.Pandoc.Readers.Metadata: export `yamlBsToRefs` [API change].
      These allow specifying an id filter so we parse only references
      that are used in the document.
    * Text.Pandoc.Parsing:
      + Export ParseError [API change].
      + Add `stateInNote` and `stateNoteNumber` to `ParserState`
      [API change].  These are used to populate note numbers for citation
      processing.
    * Fix apparent typos in sample.lua (#6729, William Lupton).
      Also make the writer less aggressive in escaping quotes.
    * Text.Pandoc.Options:
      + `defaultMathJaxURL`: use `tex-chtml-full` instead of `tex-mml-chtml`
      (#6599, Kolen Cheung).  This drops the MathML support (which we
      don't need for HTML math rendering) and includes the full JavaScript,
      which makes it possible to use `--self-contained` (though there may
      still be issues if the required math fonts aren't available).  This
      change should also reduce latency in pages with lots of formulas.
      + Add `/tex-chtml-full.js` to `defaultMathJaxURL` (#6593) Previously we
      added this in processing command line options, but not in processing
      defaults files, which was inconsistent.
    * epub.css: Fix cover page selectors and add note explaining their use
      (#6649, a-vrma).
    * Add data files needed for Text.Pandoc.Citeproc:  these include
      `default.csl` in the data directory and a `citeproc` directory that
      is only used at compile-time for biblatex localizations.  Note that we've
      added `file-embed` as a mandatory rather than a conditional depedency,
      because of the biblatex localization files.
    * Lua filters:
      + Add SimpleTable for backwards compatibility (#6575, Albert Krewinkel).
      A new type `SimpleTable` is made available to Lua filters. It is
      similar to the `Table` type in pandoc versions before 2.10;
      conversion functions from and to the new Table type are provided.
      Old filters using tables now require minimal changes and can use, e.g.,
      if PANDOC_VERSION > {2,10,1} then
      pandoc.Table = pandoc.SimpleTable
      end
      and
      function Table (tbl)
      tbl = pandoc.utils.to_simple_table(tbl)
      …
      return pandoc.utils.from_simple_table(tbl)
      end
      to work with the current pandoc version.
      + Make `attr` argument optional in `Table` constructor (Albert Krewinkel).
      This changes the Lua API. It is highly unlikely for this change to affect
      existing filters, since the documentation for the new Table constructor
      (and type) was incomplete and partly wrong before.  The Lua API is now
      more consistent, as all constructors for elements with attributes now
      take attributes as the last parameter.
    * MANUAL.txt:
    * Add a dedicated Citations section which consolidates the information
      the manual used to contain about citation processing, and incorporates
      some information formerly found in the pandoc-citeproc man page.
      + Add note about lualatex using `selnolig`.
      + Remove duplicate `seriespage` (#6568, Blake Eryx).
      + Remove lists of support extensions for markdown variants (#6604).
      Instead, offer the advice to use `--list-extensions=FORMAT`.
      + Fix position of attributes in header (Albert Krewinkel).
      + Delete obsolete section on compact and loose lists (#6684).
    * doc/lua-filters.md:
      + Add info on how to debug Lua filters (#6732, Ian Max Andolina).
      + Document Underline type and constructor (Albert Krewinkel).
      + Document `body` field (Albert Krewinkel).
      + Add missing header attribute
      + Add missing Link.title field (Albert Krewinkel).
      + Make the setting-the-date example conditional (the-solipsist).
      This makes the example a bit more realistic.
      + Remove outdated link table example.
    * doc/org.md:
      + Add section on tables (Albert Krewinkel).
      + Add section on handling of unknown directives (Albert Krewinkel).
    * CONTRIBUTING.md: fix typo (#6584, Dmitry Volodin).
    * Use golden test framework for command tests.  This means that
      `--accept` can be used to update expected output.
    * Use the `smart` extension when generating pandoc's man page (#6613).
    * Release-candidate: don't build windows i386.
      So far we haven't been able to figure out how to get
      stack to use a 32-bit ghc.
    * Use `null` instead of deprecated `Builder.isNull`.
    * Makefile:
      + Fix macospkg target to fetch target from S3 artifacts.
      + Fix pandoc-templates target to include all partials.
    * Remove duplicated dependency in pandoc.cabal (#6591, Felix Yan).
    * Sort build depends in pandoc.cabal alphabetically (#6691,
      Albert Krewinkel).
    * Add .travis.yml for macos release candidate build (#6622).
      We need to build the release candidate on Travis rather
      than GitHub actions, because GH has macos 10.15, and
      binaries compiled on that OS will not work with 10.13.
      This build is only triggered on `rc/*` branches.
    * Remove instructions for building pandoc-citeproc from CI and
      release binary build instructions.  We will no longer distribute
      pandoc-citeproc.
    * Fix math rendering in trypandoc (this broke after
      commit d8ad766d17603784b86fc5c2e1b22864125d04d1).
    * Use latest versions of skylighting, commonmark (#6589),
      comonmark-extensions, commonmark-pandoc, texmath.
    * Relax version bounds for hslua, hslua-module-text, bytestring.
    * Use released pandoc-types 1.22.  This changes the JSON
      encoding slightly for the new table types introduced
      in 1.21, so they're more consistent with the rest.
      Developers of libraries for pandoc filters will want
      to take note.
    * Fix hlint suggestions, update hlint.yaml (#6680, Christian Despres).
    * Code cleanup (#6678, Joseph C. Sible).
    * Add haddocks to functions in Text.Pandoc.Writers.Shared (Albert
      Krewinkel).
    * Remove duplicate `tshow` definition.
    * Linux release candidate build: use ghc-musl container.  This simplifies
      our build process (over using a customized alpine container).
* Tue Aug 18 2020 [email protected]
  - Replace %setup -q with the more modern %autosetup macro.
* Tue Aug 18 2020 [email protected]
  - Tweak Cabal file to accept latest version of its dependencies.
* Tue Jul 28 2020 [email protected]
  - Update pandoc to version 2.10.1.
    Upstream has edited the change log file since the last release in
    a non-trivial way, i.e. they did more than just add a new entry
    at the top. You can review the file at:
    http://hackage.haskell.org/package/pandoc-2.10.1/src/changelog.md
* Wed Jul 01 2020 [email protected]
  - Update pandoc to version 2.10.
    [#]# pandoc 2.10 (YYYY-MM-DD)
    * Use pandoc-types 1.21.  This adds two things:
      + A native Underline constructor for Inline (#6277, Vaibhav Sagar).
      + More expressive types for tables (#1024, Christian Despres).
      Tables can now take attributes; and rowspans and colspans,
      column headers, multiple row headers, table head and foot
      can all be represented.  (Note, however, that reader and
      writer support for these features is still lacking, so
      most users won't see any differences in table conversion
      yet.  These changes just lay the foundation for further
      improvements.)
    * Support new Underline element in readers and writers (#6277,
      Vaibhav Sagar).
    * Support new Table type (Christian Despres).
      The Builder.simpleTable now only adds a row to the TableHead
      when the given header row is not null. This uncovered an
      inconsistency in the readers: some would unconditionally
      emit a header filled with empty cells, even if the header
      was not present. Now every reader has the conditional
      behaviour.  Only the XWiki writer depended on the header row
      being always present; it now pads its head as necessary.
    * Add an option to disable certificate validation (#6156, Cédric Couralet,
      Cécile Chemin, Juliette Fourcot).  This commit adds the option
      `--no-check-certificate`, which disables certificate checking when
      resources are fetched by HTTP.
    * Unify defaults and markdown metadata parsers (#6328, Nikolay
      Yakimov). Clean up code in Text.Pandoc.Readers.Metadata and
      properly handle errors in `yamlToMeta`.  This fixes parsing
      of Boolean fields in metadata withinin defaults files and reduces
      code duplication.
    * Docbook reader:
      + Implement `<procedure>` (#6442, Mathieu Boespflug).
      + Implement `<phrase>` (#6438, Mathieu Boespflug).
      + Treat envar and systemitem like code (#6435, Mathieu Boespflug).
      + Implement `<replaceable>` (#6437, Mathieu Boespflug)
      + Map `<simplesect>` to unnumbered section (#6436, Mathieu Boespflug).
    * JATS reader:
      + Handle "label" element in section title (#6288).
      + Parse abstract element into metadata field of same name
      (#6480, Albert Krewinkel).
    * Jira reader (Albert Krewinkel):
      + Resolve multiple parsing problems, including issues with empty
      table cells, faulty recognition of closing emphasis characters, and
      parsing of image attributes (#6212, #6219, #6220).
      + Two consecutive markup chars are now parsed verbatim (#6343);
      styled text must not be empty.
      + Newlines are no longer allowed within styled text (#6325).
      + Links to anchors are now parsed as links (#6407).
      + Retain image attributes (#6234).  Jira images attributes as in
      `!image.jpg|align=right!` are retained as key-value pairs. Thumbnail
      images, such as `!example.gif|thumbnail!`, are marked by a
      `thumbnail` class in their attributes.
      + Use Underline for inserted text (#6237). Previously, the span was
      marked with the non-standard class `inserted`.
      + Improve icon conversion for `(/)`, `(x)`, `(!)`, `(?)`
      `(+)`, `(-)`, `(off)`, `(*)`. (#6236, #6264).
      + Support citations, attachment links, and user links (#6231, #6238,
      [#6239]).
      + Resolve parsing issues of blockquote, color (#6233, #6235).
    * HTML reader:
      + Parse attributes into table attributes.
      + Support `<bdo>` (#5794, Tristan de Cacqueray).
      + Add `summary` to list of block-level HTML tags (#6385).
      This improves support for summary/details inside Markdown.
      NOTE:  you need to include a blank line before the closing
      `</details>`, if you want the last part of the content to
      be parsed as a paragraph.
      + Fix parsing unclosed th elements in a table (#6247).
    * Commonmark reader: Implement `implicit_figures` extension (#6350).
    * Markdown Reader:
      + Fix inline code in lists (#6284, Nikolay Yakimov).
      Previously inline code containing list markers was sometimes
      parsed incorrectly.
      + Don't require blank line after grid table (#6481).
      This allows grid tables to be enclosed in fenced divs with no
      intervening blank lines.
    * LaTeX reader:
      + Don't parse beyond `\end{document}` (#6380).
      This required some internal changes to `\subfile` handling.
      + Better handling of `\lettrine`.  SmallCaps instead of Span
      for the part after the initial capital.  Ensure that both
      arguments are parsed, so that in Markdown both
      are treated as raw LateX. (Closes #6258.)
    * Org reader (Albert Krewinkel):
      + Recognize images with uppercase extensions (#6472).
      + Keep unknown keyword lines as raw org.  The lines of unknown
      keywords, like `#+SOMEWORD: value` are no longer read as metadata,
      but kept as raw `org` blocks. This ensures that more information
      is retained when round-tripping org-mode files; additionally,
      this change makes it possible to support non-standard org
      extensions via filters.
      + Unify keyword handling.  Handling of export settings and other
      keywords (like `#+LINK`) has been combined and unified.
      + Support `LATEX_HEADER_EXTRA` and `HTML_HEAD_EXTRA`
      settings.  These export settings are treated like their non-extra
      counterparts, i.e., the values are added to the `header-includes`
      metadata list.
      + Allow multiple `#+SUBTITLE` export settings.  The values of all
      lines are read as inlines and collected in the `subtitle`
      metadata field.
      + Read `#+INSTITUTE` values as text with markup.  The value is
      stored in the `institute` metadata field and used in the
      default beamer presentation template.
      + The behavior of the `#+AUTHOR` and `#+KEYWORD` export
      settings has changed: Org now allows multiple such lines
      and adds a space between the contents of each line. Pandoc
      now always parses these settings as meta inlines; setting
      values are no longer treated as comma-separated lists.
      Note that a Lua filter can be used to restore the previous
      behavior.
      + Read description lines as inlines (#6485). `#+DESCRIPTION` lines
      are now treated as text with markup. If multiple such
      lines are given, then all lines are read and separated by soft
      linebreaks.
      + Honor tex export option (#4070).  The `tex` export option can be set
      with `#+OPTION: tex:nil` and allows three settings:
      `t` (the default) causes LaTeX fragments to be parsed as TeX or added
      as raw TeX.  `nil` removes all LaTeX fragments from the document.
      `verbatim` treats LaTeX as text.
    * RST reader:
      + Pass arbitrary attributes through in code blocks (#6465).
      Exceptions: name (which becomes the id), class (which becomes the
      classes), and number-lines (which is treated specially to fit
      with pandoc highlighting).
      + Handle `date::` directive (#6276).
    * Textile reader: support `pre.` for code blocks (#6454).
    * Ipynb reader:
      + Handle application/pdf output as image (#6430).
      + Properly handle image/svg+xml as an image (#6430).
    * Docx reader:
      + Distinguish between docx parsing and docx container unpacking errors.
    * MediaWiki reader:
      + Fix `gfm_auto_identifiers` so that `-` is not replaced by `_` (#6335).
    * Vimwiki reader:
      + Add nested syntax highlighting (#6256, Vlad Hanciuta).
      Nested syntaxes are specified like this:
      ```
      {{{sql
      SELECT * FROM table
      }}}
      ```
      The preformatted code block parser has been extended to check if the
      first attribute of the block is not a `key=value` pair, and in that
      case it will be considered as a class.
    * Jira writer (Albert Krewinkel):
      + Always escape braces (#6478).  Braces are now always escaped, even
      within words or when surrounded by whitespace. Jira and
      Confluence treat braces specially.
      + Convert Underline to inserted text (`+inserted+`).
      + Add image attributes (#6234).  Image attributes are added
      to the output as image parameters. If the image has a
      class "thumbnail", then a thumbnail image is generated;
      all other attributes are discarded in this case.
    * LaTeX writer:
      + Ensure that `-M csquotes` works even in fragment mode (#6265).
      + Escape `^` specially for listings (#6460).
      + Create hypertarget for links with identifier (#6360).
      + Distinguish between single and double quotes when using enquote
      package (#6457, dbecher-ito).
      + Add support for customizable alignment of columns in beamer (#6331,
      andrebauer).
      + Add support for customizable alignment of columns in beamer
      (#4805, #4150, andrebauer).
    * HTML writer:
      + Use CSS in favor of `<br>` for display math (#6372)
      Some CSS to ensure that display math is
      displayed centered and on a new line is now included
      in the default HTML-based templates; this may be
      overridden if the user wants a different behavior.
    * Org writer:
      + Clean-up Div handling (Albert Krewinkel).
    * Docx writer:
      + Enable column and row bands for tables (#6371).
      This change will not have any effect with the default style.
      However, it enables users to use a style (via a reference.docx)
      that turns on row and/or column bands.
    * OpenDocument (and ODT) writer:
      + Add custom-style "Abstract" in metadata abstract.
      This ensures that the abstract is rendered with style Abstract.
      + Enable custom-style attribute on a Div.
      This allows you to apply a custom style to contained paragraphs.
    * DocBook writer:
      + Add id of figure to enclosed image.
      + Add personname element to docbook author (#6244).
    * FB2 writer:
      + Properly handle cover-image containing spaces (#6391).
    * Markdown writer:
      + Ensure consistent padding for pipe tables (#6240).
      + Avoid unnecessary escapes before intraword `_` when
      `intraword_underscores` extension is enabled (#6296).
    * RST writer:
      + Properly handle images with same alt text (#6194).
      Previously we created duplicate references for these in rendering RST.
    * AsciiDoc writer:
      + Add blank line after Div (#6308).
    * Haddock Writer:
      + Support Haddock tables (Joe Hermaszewski).
      See this PR on Haddock for details on the table format:
      <https://github.com/haskell/haddock/pull/718>.
    * PowerPoint writer (Jesse Rosenthal):
      + Write math input verbatim in speaker notes (#6301).
      OMML in speaker notes would lead to corrupt PowerPoint output. We now
      output the OMML verbatim as LaTeX in the speaker notes.
    * LaTeX template: Make polyglossia package options list-aware
      (#6444, Frederik Elwert).
    * Reveal.js template:
      + Update template for reveal.js 4.0.0 (#6390, Salim B).
      + Update template with newly available options (#6347, Jake Zimmerman).
      + Use CDN version of revealjs v4 by default (#6408).
    * opendocument template: Add abstract and subtitle to opendocument
      template (#6369).
    * reference.odt: clean up styles.  Add Abstract.
      Change Author, Date to centered paragraphs with no character
      styling.
    * epub.css: wrap overlong lines in highlighted code blocks (#6242).
      This fixes a problem in iBooks v2.4 with our earlier
      horizontally scrolling code blocks.  The problem seems to
      be a bug in iBooks, not pandoc, but since iBooks is a major
      target we're changing pandoc's default behavior so that
      pandoc-produced epubs work on that platform.
    * Text.Pandoc.PDF:
      + Use `--enable-local-file-access` in invoking `wkhtmltopdf` (#6474).
      `wkhtmltopdf` changed in recent versions to require this for
      access to local files.  This fixes PDF via HTML5 with `--css`.
      + Send verbose output to stderr, not stdout (#6483).
    * Text.Pandoc.MIME: Fix MIME type for TrueType fonts in EPUBs
      (#6464, Michael Reed).
    * Text.Pandoc.Shared:
      + `makeSections`: omit number attribute when unnumbered class
      is present (#6339).  Previously the attribute was included but given
      an empty value, and this caused the table of contents creation
      functions in Text.Pandoc.Writers.Shared to think these items had
      numbers, which meant that they were included in the TOC even if the
      `unlisted` class was used.
      + Deprecate `underlineSpan` in Shared in favor of
      `Text.Pandoc.Builder.underline` (Vaibhav Sagar).
      + `renderTags'`: use self-closing tag for col element (#6295).
    * Text.Pandoc.UUID: Fix `getRandomUUID`, which previously would
      return the same value twice in a row. Make `getRandomUUID`
      polymorphic in PandocMonad.  Remove `getUUID` (#6228, Joseph C. Sible).
    * Text.Pandoc.Class: Generalize `PandocIO` functions to `MonadIO`.
    * Fixed Katex standalone script (#6399, Lucas Escot).
      Global macros are now persistent when using the HTML Writer with the
      `--katex` option.
    * Lua subsystem (Albert Krewinkel):
      + Use new type PandocLua for all pandoc Lua operations (API change).
      The new type `PandocLua` is an instance of the `PandocMonad` typeclass
      and can thus be used in a way similar to `PandocIO`.
      + Use PandocError for exceptions in Lua subsystem (API change).
      The PandocError type is used throughout the Lua subsystem. All Lua
      functions throw an exception of this type if an error occurs. The
      `LuaException` type is removed and no longer exported from
      `Text.Pandoc.Lua`. In its place, a new constructor `PandocLuaError`
      is added to PandocError.
    * Lua filters: improve error messages for failing filters (#6332,
      Albert Krewinkel).  Print the Lua error properly instead of
      displaying their `show` string.
    * Use latest skylighting.  This fixes a bug with lua multiline
      comments (and may improve handling of other syntaxes as well).
      IT also adds `aria-hidden="true"` to the empty a elements, which
      helps people who use screen readers.
    * Use latest texmath.
    * Require latest doctemplates 0.8.2.
      This adds support for template pipes `first`, `rest`,
      `last`, `allbutlast`.
    * Revert  0e48a02 and dependency on base-noprelude, which hasn't
      been updated for ghc 8.10 (see #6187).
    * Dependency adjustments:
      + Allow haddock-library 1.9.x.
      + Allow hslua 1.1 (#6243, Felix Yan).
      + Allow base64-bytestring 1.1.
      + Use latest jira-wiki-markup.
      + Allow http-client 0.7.
      + Allow tasty 1.3.x.
      + Allow aeson 1.5 (#6400, Felix Yan).
      + Remove unused dependency `vector` (#6462, Laurent P. René de Cotret).
      + Bump QuickCheck upper bound.
    * Significant code cleanup and simplification (Joseph C. Sible, #6223,
      [#6209], #6225, #6229, #6226, #6340).
    * Remove unnecessary hlint ignores (#6341, Joseph C. Sible).
    * Remove obsolete RelaxedPolyRec extension (#6487, Nikolay Yakimov).
    * trypandoc improvements (Mike Tzou):
      + Add standalone option to the command text (#6210).
      + Update third party libraries.
    * MANUAL.txt:
      + Clarify template partial naming (#6476, Mauro Bieg).
      + Describe `jira` as "Jira/Confluence wiki markup" (#6351, Albert
      Krewinkel).  In the past, Jira's wiki markup was also used by -- and
      could be imported into -- Atlassian Confluence.
      + Add link to print-css.rocks (#6272, Mauro Bieg).
      + Clarify pipe table column width adjustment (#6254).
      + Fix ATX header syntax.
      + Fix misleading note about image size conversions (#6353).
      + Update links to reveal.js documentation (#6386, Salim B).
      + Separate adjacent verbatim code blocks (#6307, tom-audm).
    * org.md:
      + Document behavior of `smart` extension (#4387, Albert Krewinkel).
      + Describe all supported export options in detail.
    * lua-filters.md:
      + Fix description of BulletList Lua type (Levi Gruspe).
      + Use pandoc.system module in TikZ example (Albert
      Krewinkel).  Showcase temporary directory handling with
      `with_temporary_directory` and `with_working_directory`.
    * INSTALL.md: fix FreeBSD port link (#6422, Mo).
      The FreeBSD port was renamed from pandoc to hs-pandoc in 2010.
      The old pandoc port is still at version 1.5.1.1
    * Propagate `(DY)LD_LIBRARY_PATH` in tests (#6376, Lila).
    * Bump `cabal-version` to 2.2 (#6377).
    * Make it possible to compile using Stack on NixOS (#6439, Mathieu
      Boespflug).
    * CI action to check for commit messsage length (Nikolay Yakimov, #6398).
* Tue Jun 16 2020 [email protected]
  - Re-generate file with latest version of spec-cleaner.
* Tue May 12 2020 [email protected]
  - Add _constraints file to avoid OOM build failures
* Wed May 06 2020 [email protected]
  - Update pandoc to version 2.9.2.1.
    Upstream has edited the change log file since the last release in
    a non-trivial way, i.e. they did more than just add a new entry
    at the top. You can review the file at:
    http://hackage.haskell.org/package/pandoc-2.9.2.1/src/changelog.md
* Thu Feb 27 2020 [email protected]
  - Update pandoc to version 2.9.2.
    [#]# pandoc 2.9.2 (2020-02-15)
    * Add `csv` as an input format (#6100).  The CSV table is converted into a
      pandoc simple table.  A new module Text.Pandoc.Readers.CSV
      exports `readCSV` [API change].
    * Introduce new format variants for JATS writer (#6014, Albert Krewinkel):
    - `jats_archiving` for the "Archiving and Interchange Tag Set",
    - `jats_publishing` for the "Journal Publishing Tag Set", and
    - `jats_articleauthoring` for the "Article Authoring Tag Set."
      The `jats` output format is now an alias for `jats_archiving`.
      The module Text.Pandoc.Writers.JATS now exports
      `writeJatsArchiving`, `writeJatsPublishing`, and
      `writeJatsArticleAuthoring`, as well as the legacy
      `writeJATS` [API change].
    * `--defaults`: Support `bibliography` and `csl` fields.
      Move `addMeta` from Text.Pandoc.App.CommandLineOptions to
      Text.Pandoc.App.Opt (internal change).
    * Add timing info for filters in `--verbose` mode (#6112).
      When verbose mode is specified (verbosity == INFO), print a
      notice when running a filter and when a filter completes (including
      timing).
    * LaTeX reader:
      + Allow `&` in LaTeX citation keys (#6110).
      + Improve caption and label parsing.
      + Don't emit empty Span elements for labels.
      + Put tables with labels in a surrounding Div.
      + Resolve `\ref` to table numbers (#6137).
      + Skip comments in more places where this is needed (#6114).
      + Allow beamer overlays for all commands in all raw tex (#6043).
      This affects parsing of raw tex in LaTeX and in Markdown and
      other formats.
      + Improve parsing of raw environments (#6034).  If parsing fails
      in a raw environment (e.g. due to special characters like unescaped
      `_`), try again as a verbatim environment, which is less sensitive to
      special characters.  This allows us to capture special environments
      that change catcodes as raw tex when `-f latex+raw_tex` is used.
    * RST reader:
      + Add highlight directive (#6140, Lucas Escot).
    * MediaWiki writer:
      + Prevent triple `[[[` which confuses MediaWiki (#6119).
    * HTML reader:
      + Don't parse `data-id` as `id` attribute.  And similarly don't
      parse any `data-X` as `X` when `X` is a valid HTML attribute.
    * Org reader:
      + Simplify parsing of sub- and superscripts (#6127, Albert Krewinkel).
      Speeds up parsing of single-word, markup-less sub- and superscripts.
    * LaTeX writer:
      + Group biblatex citations even with prefix and suffix (#5849, Ethan
      Riley).  Previously biblatex citations were only grouped if there
      was no prefix.  This patch allows them to be grouped in subgroups split
      by prefixes and suffixes, which allows better citation sorting.
      + Fix regression in handling of columns in beamer slides (#6033).
      Columns in title slides were causing problems with
      slide division.
      + Fix duplicate frame classes in LaTeX/Beamer output (#6107).
    * HTML writer:
      + Fix duplicate attributes on headings (#6062), regression from 2.7.x.
      + Fix `--number-offset` with HTML TOC.  Eventually it would be worth
      adding a parameter to `makeSections` so this could be done at that
      level; then it would also affect other writers that construct
      TOC manually.
      + reveal.js: restore old behavior for 2D nesting (#6032).
      The fix to #6030 actually changed behavior, so that the
      2D nesting occurred at slide level N-1 and N, instead of
      at the top-level section.  This commit restores the v2.7.3 behavior.
      If there are more than 2 levels, the top level is horizontal
      and the rest are collapsed to vertical.
      + reveal.js: ensure that pauses work even in title slides (#5819).
    * Markdown writer:
      + Fix regression: spurious dots in markdown_mmd metadata output (#6133).
    * Docx writer:
      + Fix regression with Compact style on tight lists (#6072).
      Starting in 2.8, the docx writer no longer distinguishes between tight
      and loose lists, since the Compact style is omitted.  This is a
      side-effect of the fix to #5670, as explained in the changelog.  This
      patch fixes the problem by extending the exception currently offered to
      Plain blocks inside tables to Plain blocks inside list items.
    * Jira writer:
      + Fix output of table headers (Albert Krewinkel, #6035).
    * Add Text.Pandoc.Image with unexported svgToPng.
    * Moved html5Attributes, html4Attributes, rdfaAttributes
      from T.P.Writers.HTML (where they were unexported) to
      T.P.XML (where they are now exported).
      [API change: new exported functions]
      This allows these sets to be used elsewhere, e.g.
      in the HTML reader.
    * Text.Pandoc.Shared: Export a new function `findM` (#6125,
      Joseph C. Sible).
    * Text.Pandoc.Logging: Add `RunningFilter`, `FilterCompleted`
      constructors to LogMessage [API change].
    * Text.Pandoc.CSV: fix bug in CSV parser; previously an extra blank record
      would sometimes be inserted at the end.
    * LaTeX template: add space option to xeCJK with PassOptionsToPackage
      (#6002).  Otherwise we can get a clash with documentclasses that
      already load the package.
    * Lua filters:
      + Allow filtering of element lists (#6038, Albert Krewinkel).  Lists of
      Inline and Block elements can now be filtered via `Inlines` and
      `Blocks` functions, respectively. This is helpful if a filter
      conversion depends on the order of elements rather than a single
      element.  For example, the following filter can be used to remove all
      spaces before a citation:
      function isSpaceBeforeCite (spc, cite)
      return spc and spc.t == 'Space'
      and cite and cite.t == 'Cite'
      end
      function Inlines (inlines)
      for i = #inlines-1,1,-1 do
      if isSpaceBeforeCite(inlines[i], inlines[i+1]) then
      inlines:remove(i)
      end
      end
      return inlines
      end
      + Add methods `insert`, `remove`, and `sort` to pandoc.List
      (Albert Krewinkel).  Example of use:
      local numbers = pandoc.List {2, 3, 1}
      numbers:sort()     -- numbers is now {1, 2, 3}
      + Make `pandoc.List` a callable constructor (Albert Krewinkel).
      It is now possible to construct a new List via
      `pandoc.List()` instead of `pandoc.List:new()`.
      + Add tests for pandoc.List module (Albert Krewinkel).
    * Text.Pandoc.App.CommandLineOptions: Change `setVariable` to use `Text`
      instead of `String`.  This avoids some unnecessary unpacking.
    * Use versioned directory for windows release zipfile.
      Also remove old `make-windows-installer.bat`, superseded by GitHub
      actions workflow, and modify `pandoc.wxs` for new paths.
    * Extensive code cleanup (#6141, #6128, #6129, #6130, #6123,
      [#6105], 6102, #6117, #6124, #6115, #6116, #6111, Joseph C. Sible).
    * Fix hlint warnings (Albert Krewinkel).
    * Use latest doclayout, doctemplates (#6031).  The new version of
      doclayout fixes a memory leak that affected `--include-in-header` with
      large files (and possibly other cases involving extremely long lines).
    * Use latest texmath.
    * Use latest skylighting and fix test suite (#6086).
    * sample.lua: Fix typo in descriptive comments (#6136, Caleb Maclennan).
      Fix typo in error message (#6135).
    * Add Docker and GH Actions instructions/links to INSTALL.md.
    * Update filter documentation (#6065). Improve cabal v2 instructions.
      Remove example using pandoc API directly (we have other
      docs for that and it was outdated).
    * Lua filter docs:
      + Cross-link constructors and types (Albert Krewinkel).
      Thanks to @bpj for the idea.
      + Sort pandoc.List methods alphabetically (Albert Krewinkel).
      + Unify, fix anchors and internal links (#6061, Albert Krewinkel).
      Links and anchors now follow consistent conventions, like
      lowercase-only anchor names.  This breaks some links to specific
      sections in the document, but will make it much easier to link
      documentation in the future.
      + Clarify filter function execution order (#6059, Albert Krewinkel).
    * In docs, update URLs and use `https:` wherever possible (#6090,
      Salim B).
* Tue Jan 07 2020 [email protected]
  - Update pandoc to version 2.9.1.1.
    [#]# pandoc 2.9.1.1 (2020-01-05)
    * Markdown reader:
      + Fix parsing bug affected indented code after raw HTML (#6009, #5360).
    * LaTeX writer:
      + Fix regression in beamer slide structure with certain slide levels
      (#6030).
      + Allow framebreaks for beamer's TOC (Heiko Schlittermann, #6012)
      + Properly handle unnumbered headings level 4+ (#6018).
      Previously the `\paragraph` command was used instead of
      `\paragraph*` for unnumbered level 4 headings.
    * HTML writer:
      + Fix revealjs slide structure regression with certain slide levels
      (#6030).
      + Add newlines to make slide show output more readable.
    * Org writer:
      + Remove extra spaces from table cells (Albert Krewinkel, #6024).
    * JATS template: Update JATS dtd (Arfon Smith, #6020).  Use the archiving
      and interchange DTD rather than the more restrictive journal publishing
      DTD (which doesn't permit ext-link as a valid child).
    * Text.Pandoc.PDF: Fix `runTeXProgram` so that the input source is always
      overwritten (#6027).  Previously it wasn't overridden if the file already
      existed, which led to bad results on subsequent runs when
      `pdf-engine-opt=-output-directory=` was used to specify an explicit temp
      dir.
    * Text.Pandoc.BCP47: Change `getLang` to handle block-level contents
      (#6008).  Some readers (e.g. RST) will populate the `lang` metadata field
      with block-level content.  `getLang` has been modified to handle this.
      Previously in these cases the LaTeX writer would not properly set the
      "main language" of the document.
    * Fix `test/tables.org` (Albert Krewinkel).
    * Use HTTPS in copyright message (Felix Yan, #6010)
* Sun Dec 29 2019 [email protected]
  - Update pandoc to version 2.9.1.
    * Add Jira reader (Albert Krewinkel, #5556).
    * Jira writer: use jira-wiki-markup renderer (Albert Krewinkel,
      [#5926]). The following improvements are included in this change:
      + non-jira raw blocks are fully discarded instead of showing
      as blank lines;
      + table cells can contain multiple blocks;
      + unnecessary blank lines are removed from the output;
      + markup chars within words are properly surrounded by
      braces;
      + preserving soft linebreaks via `--wrap=preserve` is
      supported.
      Note that backslashes are rendered as HTML entities, as there
      appears no alternative to produce a plain backslash if it is
      followed by markup. This may cause problems when used with
      confluence, where rendering seems to fail in this case.
    * Fix regression with `--number-sections`. Starting with 2.8,
      `--number-sections` also had the effect of `--section-divs`,
      even if `--section-divs` was not specified.
    * Improved table of contents generation in markdown, RTF,
      commonmark, better handling cases where section headings are
      enclosed in divs.
    * Ensure that later default file values for `variable` replace
      earlier ones (5988).
    * HTML reader: Add `nav` to list of block-level tags.
    * Org reader (Albert Krewinkel):
      + Wrap named table in Div, using name as id (#5984).
      Tables which are given a name via `#+NAME:` or `#+LABEL:`
      are wrapped in an additional Div, with the name set as the
      Div's ID.
      + Report parsing errors properly.
      + Fix parsing problem for colons in headline (#5993).
    * Text.Pandoc.PDF: Ensure UTF8 when printing source in
      `--verbose` mode, avoiding an error on platforms that
      default to something other than UTF-8 (#5997).
    * Text.Pandoc.Templates: Strip directory before trying to find
      partial in data files (#5987).
    * Text.Pandoc.Shared: Improve `makeSections` so we don't get
      doubled "number" attributes in EPUB output (or anywhere
      else) (#5986).
    * Added tests for `--toc` and `--section-divs`.
    * Text.Pandoc.MIME: Added glsl MIME type for WebGL maps (#6000,
      Jared Lander).
    * MANUAL: A bit clearer explanation for `--base-header-level`.
      We now say exactly how to translate between the deprecated
      `--base-header-level` and `--shift-heading-level-by`.
    * lua-filters.md:
      + Remove spurious dot in title (#5996, Mauro Bieg).
      + Replace metadata example with image centering (#6004,
      Albert Krewinkel). Thanks to @efx for proposing this filter.

  - Update pandoc to version 2.9.
    [#]# pandoc 2.9 (PROVISIONAL)
    * Text.Pandoc.Templates [API change]
      + Add Monad wrappers `WithDefaultPartials` and `WithPartials`.
      Wrapping these around an instance of `PandocMonad` gives
      us different instances of `TemplateMonad`, with different
      search behavior in retrieving partials.
      To compile a template and limit partial search to pandoc's
      data files, use `runWithDefaultPartials (compileTemplate ...)`.
      To compile a template and allow partials to be found locally
      (either on the file system or via HTTP, in the event that
      the main template has an absolute URL), ue
      `runWithPartials (compileTemplate ...)`.
      + Export `getTemplate`, which seeks a template locally,
      or via HTTP if the template has an absolute URL, falling
      back to the data files if not found.
      + Export `compileDefaultTemplate` -- does `getDefaultTemplate`
      and compiles the result, raising an error on failure.
    * Text.Pandoc.Class [API change]
      + Remove `TemplateMonad` instances for `PandocIO` and `PandocPure`.
      These were too limiting and caused a bug whereby a local
      partial could be used even when the default template was requested.
      We now rely on instances provided in the Templates module.
    * Text.Pandoc.App.OutputSettings: Simplify template retrieval code.
    * ConTeXt template: Adjust to title formatting (#5949, Denis Maier).
      Add `\setupinterlinespace` to `title`, `subtitle`, `date` and `author`
      elements:  otherwise longer titles that run over multiple lines will look
      squashed as `\tfd` etc. won't adapt the line spacing to the font size.
    * reveal.js template: Add title-slide-attributes variable (#5981,
      Frederik Elwert).
    * More informative JSON parse error (#5973).
    * Use external emojis package (forked from pandoc).  Removed emoji data
      in Text.Pandoc.Emoji.
    * Fix regression in `makeSections` (#5965).
      Previously `hierarchicalize` (the ancestor of `makeSections`) would put
      header attributes on the containing Div.  In 2.8 this behavior changed,
      which broke some tools depending on pandoc.  Here we roll back this change,
      so that attributes again migrate from the header to the containing Div when
      `makeSections` is run.  Note that attributes are retained on the header as
      well (unlike before) -- with the exception of the `id` attribute, which of
      course cannot be duplicated.
    * Fix `--toc-depth` regression in 2.8 (#5967).
    * Use doctemplates 0.8.  Rename template 'filters' as 'pipes'
      to avoid confusion with the other notion of filter used by pandoc.
    * Fix README.md so that relative links from manual become absolute.
      Previously they'd be broken links when viewed on GitHub or Hackage.
      So we add the base URL for the pandoc manual.
    * Document display math syntax in manual.
* Sun Dec 08 2019 [email protected]
  - Update pandoc to version 2.8.1.
    [#]# pandoc 2.8.1 (2019-12-05)
    * Add `ascii_identifiers` as a supported extension for `markdown`.
      This fixes a regression in 2.8.
    * Fix regression with behavior of `--variable` (#5962).
      Previously `-Vfoo=1 -Vfoo=2` would produce a list value for foo;
      with 2.8 it produced just `2`.  This commit restores the earlier
      behavior.
    * Roll back part of of `--shift-heading-level-by` change (#5957).
      With positive heading shifts, starting in 2.8 this option
      caused metadata titles to be removed and changed to regular
      headings.  This behavior is incompatible with the old
      behavior of `--base-header-level` and breaks old workflows,
      so we have rolled back the change. Note that there is now an
      asymmetry in positive and negative heading level shifts:
      With positive shifts, the metadata title stays the same and
      does not get changed to a heading in the body, while with
      negative shifts, a heading can be converted into the
      metadata title.
    * Text.Pandoc.Shared: Fix `makeSections` so it doesn't turn
      column Divs into sections.
    * HTML writer: add task-list class to ul if all elements are
      task list items.  This will allow styling unordered task
      lists in a way that omits the bullet.
    * HTML-based templates: Add CSS to suppress bullet on unordered task lists.
    * ConTeXt template: Fix `\startcslreferences` and use ConTeXt syntax
      conventions (#5945, Denis Maier).  The old version had a too large
      a skip at the beginning of the reference list.
    * LaTeX template: keep the `\author{}` command even if author is not
      specified (#5961, Yihui Xie).  Avoids a LaTeX warning.
    * Generate Emoji module with TH.
      + Add Text.Pandoc.Emoji.TH.
      + Replace long literal list in Text.Pandoc.Emoji with one-liner
      generating it from `emoji.json` using TH.
      + Add Makefile target to download `emoji.json`.
      + Remove `tools/emoji.hs`.
    * Increase GC allocation space for compilation in cabal.project.
    * Clean up manual on PDF generation backend options (#5940).
    * Update release checklist to include code signing step and update
      Windows release-candidate builds (#5950).
* Sun Dec 01 2019 [email protected]
  - Update pandoc to version 2.8.0.1.
    Upstream has edited the change log file since the last release in
    a non-trivial way, i.e. they did more than just add a new entry
    at the top. You can review the file at:
    http://hackage.haskell.org/package/pandoc-2.8.0.1/src/changelog.md
* Sat Nov 23 2019 [email protected]
  - Update pandoc to version 2.8.
    Upstream has renamed and modified the change log file(s) in this
    release. Unfortunately, the automatic updater cannot reliable
    determine relevant entries for this release.
* Fri Nov 08 2019 [email protected]
  - Drop obsolete group attributes.
* Fri Jun 14 2019 [email protected]
  - Update pandoc to version 2.7.3.
    pandoc (2.7.3)
    * Add `jira` (Atlassian's Jira wiki markup) as output format (#2497,
      Albert Krewinkel).
    * Add `tex_math_dollars` to `multimarkdownExtensions` (#5512).
      This form is now supported in multimarkdown,
      in addition to `tex_math_double_backslash`.
    * Fix `--self-contained` so it works when output format has extensions.
      Previously if you used `--self-contained` with `html-smart` or
      `html+smart`, it wouldn't work.
    * Add template variable `curdir` with working directory
      from which pandoc is run (#5464).
    * Markdown reader: don't create implicit reference for empty header
      (#5549).
    * Muse reader: allow images inside link descriptions (Alexander Krotov).
    * HTML reader: epub related fixes.
      + With epub extensions, check for `epub:type` in addition to `type`.
      + Fix problem with noteref parsing which caused block-level
      content to be eaten with the noteref.
      + Rename `pAnyTag` to `pAny`.
      + Refactor note resolution.
      + Trim definition list terms (Alexander Krotov).
    * LaTeX reader:
      + Add braces when resolving `\DeclareMathOperator`
      (#5441).  These seem to be needed for xelatex but not pdflatex.
      + Allow newlines in `\mintinline`.
      + Pass through unknown listings language as class (#5540).
      Previously if the language was not in the list of languages supported
      by listings, it would not be added as a class, so highlighting
      would not be triggered.
      + `rawLaTeXInline`: Include trailing `{}`s in raw latex commands (#5439).
      This change affects the markdown reader and other readers that allow raw
      LaTeX.  Previously, trailing `{}` would be included for unknown
      commands, but not for known commands.  However, they are sometimes used
      to avoid a trailing space after the command.  The chances that a `{}`
      after a LaTeX command is not part of the command are very small.
    * MediaWiki reader: handle multiple attributes in table row (#5471,
      chinapedia).
    * Docx reader: Add support for `w:rtl` (#5545).  Elements with this
      property are put into Span inlines with `dir="rtl"`.
    * DocBook reader: Issue `IgnoredElement` warnings.
    * Org reader (Albert Krewinkel):
      + Fix planning elements in headers level 3 and higher
      (#5494).  Planning info is now always placed before
      the subtree contents.  Previously, the planning info was placed after
      the content if the header's subtree was converted to a list, which
      happens with headers of level 3 and higher per default.
      + Omit, but warn about unknown export options.  Unknown export
      options are properly ignored and omitted from the output.
      + Prefer plain symbols over math symbols (#5483).
      Symbols like `\alpha` are output plain and unemphasized, not as math.
      + Recognize emphasis after TODO/DONE keyword (#5484).
    * FB2 reader:
      + Skip unknown elements rather than throwing errors (#5560).
      Sometimes custom elements are used (e.g. `id` element
      inside `author`); previously the reader would halt with an error.
      Now it skips the element and issues an `IgnoredElement` warning.
      + Parse notes (#5493, Alexander Krotov).
      + Internal improvements (Alexander Krotov).
    * OpenDocument writer:  Roll back automatic figure/table numbering
      (#5474).  This was added in pandoc 2.7.2, but it makes it impossible
      to use pandoc-crossref. So this has been rolled back for now,
      until we find a good solution to make this behavior optional
      (or a creative way to let pandoc-crossref and this feature
      to coexist).
    * New module Text.Pandoc.Writers.Jira, exporting `writeJira` [API
      change] (Albert Krewinkel).
    * EPUB writer:
      + Don't include 'landmarks' if there aren't any.
      Previously we could get an empty ol element, which caused
      validation errors with epubcheck.
      + Ensure unique ids for styleesheets in content.opf (#5463).
      + Make stylesheet link compatible with kindlegen (#5466,
      Eric Schrijver).  Pandoc omitted `type="text/css"` from both
      `<style>` and `<rel="stylesheet">` elements in all templates, which
      is valid according to the spec. However, Amazon’s kindlegen software
      relies on this attribute on `<link>` elements when detecting
      stylesheets to include.
    * HTML writer:
      + Output video and audio elements depending on file
      extension of the image path (Mauro Bieg).
      + Emit empty alt tag in figures (#5518, Mauro Bieg).
      The same text is already in the <figcaption> and
      screen-readers would read it twice, see #4737.
      + Don't add variation selector if it's already there.
      This fixes round-trip failures.
      + Prevent gratuitious emojification on iOS (#5469).
      iOS chooses to render a number of Unicode entities, including '↩', as
      big colorful emoji.  This can be defeated by appending Unicode VARIATION
      SELECTOR-15'/'VARIATION SELECTOR-16'.  So we now append this character
      when escaping strings, for both '↩' and '↔'.  If other characters prove
      problematic, they can simply be added to `needsVariationSelector`.
      + Add `class="heading"` to level 7+ Headers rendered as `<p>` elements
      (#5457).
    * RST writer: treat Span with no attributes as transparent (#5446).
      Previously an Emph inside a Span was being treated as
      nested markup and ignored.  With this patch, the Span
      is just ignored.
    * LaTeX writer:
      + Include inline code attributes with `--listings` (#5420).
      + Don't produce columns environment unless beamer (#5485).
      + Fix footnote in image caption.  Regression: the fix for #4683 broke
      this case.
      + Don't highlight code in headings (#5574).  This causes
      compilation errors.
      + Use `\mbox` to get proper behavior inside `\sout` (#5529).
    * EPUB writer: Fix document section assignments (#5546).
      For example, introduction should go in bodymatter, not frontmatter, and
      epigraph, conclusion, and afterward should go in bodymatter, not
      backmatter.  For the full list of assignments, see the manual.
    * Markdown writer:
      + Add backslashes to avoid unwanted interpretation of
      definition list terms as other kinds of block (#554).
      + Ensure the code fence is long enough (#5519).
      Previously too few backticks were used when the code block
      contained an indented line of backticks.  (Ditto tildes.)
      + Handle labels with integer names (Jesse Rosenthal, #5495).
      Previously if labels had integer names, it could produce a conflict
      with auto-labeled reference links. Now we test for a conflict and
      find the next available integer.  This involves adding a new state
      variable `stPrevRefs` to keep track of refs used in other document
      parts when using `--reference-location=block|section`
    * Textile writer: fix closing tag for math output (Albert Krewinkel).
      Opening and closing tag for math output match now.
    * Org writer: always indent src blocks content by 2 spaces (#5440, Albert
      Krewinkel).  Emacs always uses two spaces when indenting the content of
      src blocks, e.g., when exiting a `C-c '` edit-buffer. Pandoc used to
      indent contents by the space-equivalent of one tab, but now always uses
      two spaces, too.
    * Asciidoc writer:
      + Use `` `+...+` `` form for inline code.
      The old `` `a__b__c` `` yields emphasis inside code in asciidoc.
      To get a pure literal code span, use `` `+a__b__c+` ``.
      + Use proper smart quotes with asciidoctor (#5487).
      Asciidoctor has a different format for smart quotes.
      + Use doubled ## when necessary for spans (#5566).
      + Ensure correct nesting of strong/emph (#5565): strong
      must be the outer element.
    * JATS writer:
      + Wrap elements with p when needed (#5570).  The JATS spec restricts
      what elements can go inside `fn` and `list-item`.  So we wrap other
      elements inside `<p specific-use="wrapper">` when needed.
      + Properly handle footnotes (#5511) according to "best practice."
      (Group them at the end in `<fn-group>` and use `<xref>` elements
      to link them.)
      + Fix citations with PMID so they validate (#5481).  This includes
      an update to data/jats.csl.
      + Ensure validity of `<pub-date>` by parsing the date and
      extracting year, month, and day, as expected.  Also add an
      iso-8601-date attribute automatically.
      + Don't use `<break>` element for LineBreak. It is only
      allowed in a few special contexts, and not in `<p>` elements.
      + Don't make `<string-name>` a child of `<string>`, which is illegal.
    * FB2 writer:
      + Do not wrap note references into `<sup>` and brackets
      (Alexander Krotov).  Existing FB2 readers, such as FBReader, already
      display links with type="note" as a superscript.
      + Use genre metadata field (#5478).
    * Muse writer: do not escape empty line after `<br>` (Alexander Krotov).
    * Add unicode code point in "Missing character" warning (#5538).
      If the character isn't in the console font, the message is pretty useless,
      so we show the code point for anything non-ASCII.
    * Lua: add Version type to simplify comparisons (Albert Krewinkel).
      Version specifiers like `PANDOC_VERSION` and `PANDOC_API_VERSION` are
      turned into `Version` objects. The objects simplify version-appropriate
      comparisons while maintaining backward-compatibility.
      A function `pandoc.types.Version` is added as part of the newly
      introduced module `pandoc.types`, allowing users to create version
      objects in scripts.
    * pandoc lua module (Albert Krewinkel):
    - Fix deletion of nonexistent attributes (#5569).
    - Better tests for Attr and AttributeList.
    * pandoc.mediabag lua module (Albert Krewinkel):
      + Add function `delete` for deleting a single item.
      + Add function `empty` for removing all entries.
      + Add function `items` for iterating over mediabag.
    * Text.Pandoc.Class: Fix handling of `file:` URL scheme in
      `downloadOrRead` (#5517, Mauro Bieg).  Previously `file:/`
      URLs were handled wrongly and pandoc attempted to make HTTP
      requests, which failed.
    * Text.Pandoc.MIME: add `mediaCategory` [API change] (Mauro Bieg).
    * Text.Pandoc.Shared:
      + Add `onlySimpleTableCells` [API change]
      (Mauro Bieg) and use this to consolidate simple-table detection
      (#5524).  This fixes an inconsistency in the HTML reader, which did not
      treat tables with `<p>` inside cells as simple.
      + `metaToJSON`: treat digits starting with 0 as a string, not a number
      (#5479).  This fixes a regression in YAML metadata in pandoc 2.7.2.
    * Text.Pandoc.Logging: Add `IgnoredElement` constructor for
      `LogMessage`.  `SkippedConetnt` doesn't work for some XML-based
      readers which don't have access to parsec source positions.
    * Text.Pandoc.Asciify: Add Turkish undotted-i (#5433, Mauro Bieg).
    * Improve output of Lua tests (#5499, Albert Krewinkel).
      This makes use of tasty-lua, a package to write tests in Lua
      and integrate the results into Tasty output. Test output becomes
      more informative: individual tests and test groups become visible
      in test output. Failures are reported with helpful error messages.
    * Lua: add `pandoc.system` module (#5468, Albert Krewinkel).
      The `system` Lua module provides utility functions to interact with the
      operating- and file system. E.g.
      `print(pandoc.system.get_current_directory())`
      or
      ```lua
      pandoc.system.with_temporary_directory('tikz', function (dir)
    - - write and compile a TikZ file with pdflatex
      end)
      ```
    * LaTeX template: Add pdflang to hypersetup if lang is set (#5443).
    * beamer template: Fix using Beamer with geometry (#5505, Daniel Maslowski).
      Beamer already loads geometry, so we need to use the `\geometry`
      command to set geometry options.
    * EPUB2/3 templates: Move inline styles to default epub.css (#5466).
      NOTE: Those who use a custom CSS stylesheet with EPUB should
      add these lines:
      code{ white-space: pre-wrap; }
      span.smallcaps{ font-variant: small-caps; }
      span.underline{ text-decoration: underline; }
      q { quotes: "“" "”" "‘" "’"; }
      div.column{ display: inline-block; vertical-align: top; width: 50%; }
    * reveal.js template:
      + Updates for revealjs 3.8.0 (#5435, ebiim).
      + Remove reference to head.min.js (#5448, Winnie Hellmann).
      NOTE: users will need to update reveal.js to at least 3.8.0
      for their presentations generated with this version of pandoc
      to work correctly.
    * Text.Pandoc.PDF:
      + Replace `</>` with literal `/` (#5451).
      We use forward-slash for a directory separator in tmpDir,
      even on Windows (because that's what tex likes).  So we
      should not put a backslash between the tmpDir and the
      filename on Windows.  This is harmless enough in normal
      Windows setups, but it breaks on Cygwin.
      Thanks to @cc2x for noticing and diagnosing the problem.
      + Allow use of `-output-directory` in `--pdf-engine-opt` (#5462).
      This is currently possible with `mklatex` and `-outdir`, but
      was not yet possible with xelatex and `-output-directory`.
      + For PDF via ms/pdfroff, make TOC appear at beginning and in
      PDF bookmarks (#5553).  Previously the TOC appeared at the end
      of the document, and was not bookmarked.  To keep it at the end,
      add `--pdf-engine-opt=--no-toc-relocation` to your command line.
    * Fix broken links in documents (#5473, Shim Myeongseob).
      Also, use absolute links to pandoc.org when possible, so that
      the links can be followed by people viewing these documents
      on GitHub.
    * Improved sample lua tikz filter in lua-filters docs (#5445,
      Matthew Doty).  There are three changes:
      + It only processes elements which begin with `\begin{tikzpicture}`
      + It uses pdf2svg instead of imagemagick to preserve fidelity
      + The images produced have transparent backgrounds
    * MANUAL.txt:
      + Add note about `title-meta`, `author-meta`, `date-meta` (#5486).
      + Fix typo (#5489, Christian Krause).
    * add test/tables.xwiki to git and pandoc.cabal (#5498, Mauro Bieg).
    * Disable missing-home-modules warning in `stack.yaml`.
      Otherwise `stack ghci` fails.
* Thu May 16 2019 [email protected]
  - Update _constraints
* Sun Apr 07 2019 [email protected]
  - Update pandoc to version 2.7.2.
    pandoc (2.7.2)
    * Add XWiki writer (#1800, Derek Chen-Becker).
      Add `Text.Pandoc.Writers.XWiki`, exporting `writeXWiki` [API change].
    * Dokuwiki Reader: parse single curly brace (#5416, Mauro Bieg).
    * Vimwiki reader: improve handling of internal links (#5414).
      We no longer append `.html` to link targets, and we add a title
      `wikilink`.  This mirrors behavior of other wiki readers.  Generally
      the `.html` extension is not wanted.  It may be important for output
      to HTML in certain circumstances, but it can always be added using a
      filter that matches on links with title `wikilink`.
      If your workflow requires the current behavior, here is a lua filter
      that will add the `.html` extension:
      ```lua
      function Link(el)
      if el.title == 'wikilink' then
      el.target = el.target .. ".html"
      end
      return el
      end
      ```
    * ipynb reader:
      + Use format `ipynb` for raw cell where no format given.
      + Avoid introducing spurious `.0` on integers in metadata.
    * Markdown reader: fenced div takes priority over setext header.
    * HTML reader: read `data-foo` attribute into `foo` (#5392).
      The HTML writer adds the `data-` prefix for HTML5 for nonstandard
      attributes.  But the attributes are represented in the AST without
      the `data-` prefix, so we should strip this when reading HTML.
    * LaTeX reader: Improve autolink detection (#5340).
    * PowerPoint writer (Jesse Rosenthal):
      + Expand builtin reference doc to model all layouts.
      The previous built-in reference doc had only title and content
      layouts. Add in a section-header slide and a two-content slide, so
      users can more easily modify it to build their own templates.
      + Always open up in slide view.  When editing a
      template/reference-doc, the user might be in Master view, but when
      producing a slide show, it is assumed that slide view will be
      desired.
      + Remove `handoutsMasterList` from template presentation.xml
      + Fix numerous errors in templating (#5402). Previously, some templates
      produced by Office 365 (MacOS) would not render with `--reference-doc`
      correctly. We now apply correct shapes for content, and build
      shape trees correctly.
      + Make default placeholder type for template lookup.
      + Apply speaker notes to metadata slide if applicable.
      + Test for speaker notes after breaking header.
      + Correctly handle notes after section-title header.
      Previously, if notes came after a section-title header (ie, a level-1
      header in a slide-level=2 presentation), they would go on the next
      slide. This keeps them on the slide with the header.
      + Internal improvements.
    * ipynb writer:
      + Use format `ipynb` for raw cell where no format given.
      According to nbformat docs, this is supposed to render in every
      format.  We don't do that, but we at least preserve it as a raw
      block in markdown, so you can round-trip.
      + Consolidate adjacent raw blocks.  Sometimes pandoc creates two
      HTML blocks, e.g. one for the open tag and one for a close tag.
      If these aren't consolidated, only one will show up in output cell.
      + Fixed carry-over of nbformat from metadata.
      + Preserve `nbformat_minor` if it's given.  This helps with round-tripping.
    * LaTeX writer:
      + Avoid inadvertently creating ?` or !` ligatures (#5407).
      These are upside down ? and !, resp.
      + Fix footnotes in table caption and cells (#5367).  This fixes a
      bug wherein footnotes appeared in the wrong order, and with
      duplicate numbers, when in table captions and cells.
      We now use regular `\footnote` commands, even in the table
      caption and the minipages containing cells. Apparently
      longtable knows how to handle this.
    * HTML writer: Don't add data- prefix to RDFa attributes (#5403).
    * JATS writer: Ensure that plain strings go inside `<pub-id>` tag (#5397).
    * Markdown writer:
      + Better rendering of numbers (#5398).  If the number is integral,
      we render it as an integral not a float.
      + Proper rendering of empty map in YAML metadata (#5398).  Should
      be `{}`, not empty string.
      + Properly escape attributes in Markdown writer (#5369).
      + Be sure implicit figures work in list contexts (#5368).
      Previously they would sometimes not work: e.g., when they
      occured in final paragraphs in lists that were originally
      parsed as Plain and converted later using PlainToPara.
    * Docx writer: Use `w:br` without attributes for line breaks (#5377).
      We previously added the attribute `type="textWrapping"`, but
      this causes problems on Word Online.
    * LaTeX template (Andrew Dunning):
      + Ensure correct heading/table order (#5365).  Improve workaround
      (#1658) for tables following headings.  The new solution works whether
      or not the `indent` variable is enabled.
      + Remove `subparagraph` variable. The default is now to use run-in
      style for level 4 and 5 headings (`\paragraph` and `\subparagraph`).
      To get the previous default behavior (where these were formatted as
      blocks, like `\subsubsection`), set the `block-headings` variable.
      + Add pandoc to PDF metadata (#5388).
      + Group graphics-related code (#5389).
      + Move `\setstretch` after front matter (#5179).  Ensures that
      `\maketitle`, `\tableofcontents`, and so forth are not affected by
      changes to line spacing.
    * Update data/jats.csl to avoid commas between name-part elements
      (#5397).
    * Add support for golang (`go`) with `--listings` (#5427).
    * Text.Pandoc.Shared - improve `metaToJSON` behavior with numbers.
      We now do a better job marshalling numbers from MetaString
      or MetaInlines into JSON Number.
    * Text.Pandoc.Writers.Shared: `metaValueToJSON`: use Number Values for
      integers.  Pandoc's MetaValue doesn't have a distinguished number type,
      so numbers are put in MetaStrings.  If the MetaString consists
      entirely of digits, we convert it to a Number.  We should probably
      consider adding a MetaNumber constructor to MetaValue, for better
      round-tripping with JSON etc.  This change aids round-tripping in
      ipynb metadata fields, like `toc_depth`.
    * Text.Pandoc.Class: `fetchItem`: don't treat UNC paths as
      protocol-relative URLs (#5127).  These are paths beginning `//?/UNC/...`.
    * Text.Pandoc.ImageSize: Improve `pdfSize` so it handles
      a wider range of PDFs (#4322, with help from Richard Davis).
    * Text.Pandoc.Pretty: avoid stack overflow by using strict sum (#5401).
    * Fix harmless error in file-scope code (#5422).
    * MANUAL.txt:
      + Improve 'header' and 'heading' usage (#5423, Andrew
      Dunning).  The term 'header' was being used where 'heading'
      is more appropriate.
      + Add paragraph on options affecting markdown in ipynb.
    * stack.yaml - remove -Wmissing-home-modules
      This seems to cause problems with stack ghci.  Remove RTS options.
    * Add ghc-options to cabal.project.
    * appveyor.yml - use ghc 8.6.4.  Fixes segfault issues on Windows (#5037).
    * linux build process: Remove clone of pandoc-citeproc (#5366).
      It wasn't being used; cabal.project specifies the version to use.
* Fri Mar 15 2019 [email protected]
  - Update pandoc to version 2.7.1.
    Upstream has edited the change log file since the last release in
    a non-trivial way, i.e. they did more than just add a new entry
    at the top. You can review the file at:
    http://hackage.haskell.org/package/pandoc-2.7.1/src/changelog
* Mon Mar 04 2019 [email protected]
  - Update pandoc to version 2.7.

* Fri Feb 01 2019 [email protected]
  - Update pandoc to version 2.6.
    pandoc (2.6) PROVISIONAL
    * Support ipynb (Jupyter notebook) as input and output format.
      + Add `ipynb` as input and output format (extension `.ipynb`).
      + Added Text.Pandoc.Readers.Ipynb [API change].
      + Added Text.Pandoc.Writers.Ipynb [API change].
      + Add `PandocIpynbDecodingError` constructor to Text.Pandoc.Error.Error
      [API change].
      + Depend on ipynb library.
      + Note: there is no template for ipynb.
    * Add DokuWiki reader (#1792, Alexander Krotov).  This adds
      Text.Pandoc.Readers.DokuWiki [API change], and adds `dokuwiki`
      as an input format.
    * Implement task lists (#3051, Mauro Bieg). Added `task_lists`
      extension. Task lists are supported from markdown and gfm input.
      They should work, to some degree, in all output formats, though in
      most formats you'll get a bullet list with a unicode character for
      the box. In HTML, you get checkboxes and in LaTeX/PDF output, a
      box is used as the list marker. API changes:
      + Added constructor `Ext_task_lists` to `Extension`.
      + Added `taskListItemFromAscii` and `taskListItemToAscii` to
      Text.Pandoc.Shared.
    * Allow some command line options to take URL in addition to FILE.
      `--include-in-header`, `--include-before-body`, `--include-after-body`.
    * HTML reader:
      + Handle empty `start` attribute (see #5162).
      + Treat `textarea` as a verbatim environment (#5241) and preserve
      spacing.
    * RST reader:
      + Change treatment of `number-lines` directive (Brian Leung,
      [#5207]). Directives of this type without numeric inputs should
      not have a `startFrom` attribute; with a blank value, the
      writers can produce extra whitespace.
      + Removed superfluous `sourceCode` class on code blocks (#5047).
      + Handle `sourcecode` directive as synonynm for `code` (#5204).
    * Markdown reader:
      + Remove `sourceCode` class for literate Haskell code blocks
      (#5047). Reverse order of `literate` and `haskell` classes on
      code blocks when parsing literate Haskell, so `haskell` is
      first.
      + Treat `<textarea>` as a verbatim environment (#5241).
    * Org reader:
      + Handle `minlevel` option differently (#5190, Brian Leung).
      When `minlevel` exceeds the original minimum level observed in
      the file to be included, every heading should be shifted
      rightward.
      + Allow for case of `:minlevel == 0` (#5190).
      + Fix treatment of links to images (#5191, Albert Krewinkel).
      Links with descriptions which are pointing to images are no
      longer parsed as inline images, but as links.
      + Add support for #+SELECT_TAGS (Brian Leung).
      + Separate filtering logic from conversion function (Brian Leung).
    * TWiki reader: Fix performance issue with underscores (#3921).
    * MediaWiki reader: use `_` instead of `-` in auto-identifiers (#4731).
      We may not still be exactly matching mediawiki's algorithm.
    * LaTeX reader:
      + Remove `sourceCode` class for literate Haskell code blocks
      (#5047). Reverse order of `literate` and `haskell` classes on
      code blocks when parsing literate Haskell, so `haskell` is
      first.
      + Support `\DeclareMathOperator` (#5149).
      + Support `\inputminted` (#5103).
      + Support `\endinput` (#5233).
      + Allow includes with dots like `cc_by_4.0`.  Previously the `.0`
      was interpreted as a file extension, leading pandoc not to add
      `.tex` (and thus not to find the file).  The new behavior matches
      tex more closely.
    * Man reader:
      + Use `mapLeft` from Shared instead of defining own.
    * Docx reader (Jesse Rosenthal):
      + Handle level overrides (#5134).
    * Docx writer:
      + Support custom properties (#3024, #5252, Agustín Martín Barbero).
      Also supports additional core properties:  `subject`, `lang`,
      `category`, `description`.
      + Make Level into a real type, instead of an alias for a tuple
      (Jesse Rosenthal).
    * ICML writer (Mauro Bieg):
      + Support custom-styles (#5137, see #2106).
      + Support unnumbered headers (#5140).
    * Texinfo writer: Use header identifier for anchor if present (#4731).
      Previously we were overwriting an existing identifier with a new one.
    * Org writer: Preserve line-numbering for example and code blocks
      (Brian Leung).
    * Man/Ms writers: Don't escape `-` as `\-`. The `\-` gets rendered
      in HTML and PDF as a unicode minus sign.
    * Ms writer: Ensure we have a newline after .EN in disply math (#5251).
    * RST writer: Don't wrap simple table header lines (#5128).
    * Asciidoc writer: Shorter delimiters for tables, blockquotes
      (#4364). This matches asciidoctor reference docs.
    * Dokuwiki writer: Remove automatic `:` prefix before internal image
      links (#5183, Damien Clochard).  This prevented users from making
      relative image links.
    * Zimwiki writer: remove automatic colon prefix before internal
      images (#5183, Damien Clochard).
    * MediaWiki writer: fix caption, use 'thumb' instead of 'frame'
      (#5105). Captions used to have the word 'caption' prepended; this
      has been removed. Also, 'thumb' is used instead of 'frame' to
      allow images to be resized.
    * reveal.js writer:
      + Ensure that we don't get > 2 levels of section nesting,
      even with slide level > 2 (#5168).
      + If slide level == N but there is no N-level header, make
      sure the next header with level > N gets treated as a slide
      and put in a section, rather than remaining loose (#5168).
    * Markdown writer:
      + Make `plain` RawBlocks pass through in `plain` output.
      + Include needed whitespace after HTML figure (#5121).
      We use HTML for a figure in markdown dialects that can't
      represent it natively.
    * Commonmark writer:
      + Fix handling of SoftBreak with `hard_line_breaks` (#5195).
      + Implement `--toc` (`writerTableOfContents`)
      in commonmark/gfm writers (#5172).
    * EPUB writer:
      + Ensure that picture transforms are done on metadata too.
      + Small fixes to `nav.xhtml`:
      Add 'landmarks' id attribute to the landmarks nav.
      Replace old default CSS removing numbers from ol.toc li
      with new rules that match `nav#toc ol, nav#landmarks ol`.
      We keep the `toc` class on `ol` for backwards compatibility.
    * LaTeX writer:
      + Make raw content marked `beamer` pass through in `beamer`
      output (pandoc/lua-filters#40).
      + Beamer: avoid duplicated `fragile` property in some cases
      (#5208).
      + Add `#` special characters for listings (#4939).
      This character needs special handling in `\lstinline`.
    * RTF writer: use `toTableOfContents` from Shared to replace
      old duplicated code.
    * Pptx writer:
      + Support custom properties.  Also supports additional core
      properties: `subject`, `category`, `description` (#5252,
      Agustín Martín Barbero).
      + Use `toTableOfContents` from Shared to replace old duplicated code.
    * ODT writer (Augustín Martín Barbero):
      + Fix typo in custom properties (#2839).
      + Improve standard properties, including the following core
      properties: `generator` (Pandoc/VERSION), `description`, `subject`,
      `keywords`, `initial-creator` (from authors), `creation-date`
      (actual creation date) (#5252).
    * Custom writers:
      + Allow '-' in filenames for custom lua writers (#5187).
      + sample.lua: add `SingleQuoted`, `DoubleQuoted` (#5104).
      + sample.lua: Add a missing `>` (MichaWiedenmann).
    * reveal.js template:  Add `zoomKey` config (#4249).
    * HTML5 template: Remove unnecessary type="text/css" on style and
      link for HTML5 (#5146).
    * LaTeX template (Andrew Dunning, except where noted):
      + Prevent fontspec from scaling `mainfont` to match the default
      font, Latin Modern. A main font set to 12pt could
      previously appear between 11pt to 13pt depending on its design.
      To return to the earlier rendering, use `-V
      mainfontoptions="Scale=MatchLowercase"` (#5212, #5218).
      + Display monospaced fonts without TeX ligatures when using
      `--pdf-engine=lualatex`. It now matches the behaviour of other
      engines (#5212, #5218).
      + Remove the deprecated `romanfont` variable. The functionality of
      `mainfont` is identical (#5218).
      + Render `\subtitle` with the standard document classes.
      Previously, `subtitle` only appeared when using the KOMA-Script
      classes or Beamer (#5213, #5244).
      + Use Babel instead of Polyglossia for LuaLaTeX. This avoids
      several language selection problems, notably with retaining
      French spacing conventions when switching to a verbatim
      environment or another language; and in printing Greek text
      without hyphenation (#5193).
      + Use the [`xurl`](https://ctan.org/pkg/xurl) package if
      available, improving the appearance of URLs by allowing them to
      break at additional points (#5193).
      + Use [`bookmark`](https://ctan.org/pkg/bookmark) if available
      to correct heading levels in PDF bookmarks: see the [KOMA-Script
      3.26 release notes](https://komascript.de/release3.26) (#5193).
      + Require the [`xcolor`](https://ctan.org/pkg/xcolor) package to
      avoid a possible error when using additional packages alongside
      footnotes in tables (#5193, closes #4861).
      + Remove obsolete `fixltx2e` package, which has no functionality
      with TeX Live 2015 or later (#5193).
      + Allow multiple `fontfamilies.options` (#5193, closes #5194).
      + Restrict `institute` variable to Beamer (#5219).
      + Use [`footnotehyper`](https://ctan.org/pkg/footnotehyper)
      package if available to make footnotes in tables compatible
      with `hyperref` (#5234).
      + Number parts and chapters in book classes only if the
      `numbersections` variable is set, for consistency with other
      output formats. To return to the previous behaviour, use
      `-V numbersections -V secnumdepth=0` (#5235).
      + Reindent file (#5193).
      + Use built-in parskip handling with KOMA-Script classes (#5143, Enno).
      + Set default listings language for lua, assembler (#5227, John
      MacFarlane).  Otherwise we get an error when trying to compile code
      with lua or assembler code.  To change the default dialect
      (currenty 5.3 for lua and x86masm for assembler), you can use
      `--include-in-header` to inject something like
      `\lstset{defaultdialect=[5.2]Lua}`.
    * Text.Pandoc.Readers: Changed types of `readJSON`; it now runs
      in an instance of PandocMonad, like the other readers and
      writers.  [API change]
    * Text.Pandoc.Writers: Changed types of `writeJSON`; it now runs
      in an instance of PandocMonad, like the other readers and
      writers.  [API change]
    * Text.Pandoc.Error: Added `PandocUTF8DecodingError` constructor
      for `PandocError`. [API change]
    * Text.Pandoc.Writers.Shared - add `toTableOfContents`. [API change]
      This is refactored out from the Markdown writer.
      It can be used in other writers to create a table of contents.
    * Improve error messages for UTF-8 decoding errors. Now we give
      the filename and byte offset (#4765).
    * Text.Pandoc.XML: Strip out illegal XML characters in
      `escapeXMLString` (#5119).
    * Text.Pandoc.Process: update `pipeProcess` (Albert Krewinkel).
      The implementation of `pipeProcess` was rewritten to fix sporadic
      failures caused by prematurely closed pipes.
    * Use `safeRead` instead of `read` everywhere in the code
      (John MacFarlane, Mauro Bieg, #5162, #5180).
    * Text.Pandoc.SelfContained: Decompress `.svgz` when
      converting to `data:` URI (#5163, Alexander Krotov).
    * Text.Pandoc.Parsing: Remove unused `HasHeaderMap`
      (#5175, Alexander Krotov). [API change]
    * Normalize Windows paths to account for change in ghc 8.6 (#5127).
      When pandoc is compiled with ghc 8.6, Windows paths are treated
      differently, and paths beginning `\\server` no longer work.
      This commit rewrites such patsh to `\\?\UNC\server` which works.
      The change operates at the level of argument parsing, so it
      only affects the command line program.
    * Simplify/fix reading of `--metadata` values on command line
      to avoid problems relating to hvr/HsYAML#7 (#5177).
    * data/pandoc.lua: auto-fix nested constructor arguments (Albert
      Krewinkel).  Incorrect types to pandoc element constructors are
      automatically converted to the correct types when possible. This was
      already done for most constructors, but conversions are now also done
      for nested types (like lists of lists).
    * Removed custom Setup.hs, use build-type: simple. The only thing we
      gained from the custom build was automatic installation of the man
      page when using 'cabal install'. But custom builds cause problems,
      e.g., with cross-compilation. Installation of the man page is
      better handled by packagers. Note to packagers (e.g. Debian): it
      may be necessary to add a step installing the man page with the
      next release.
    * Allow latest http-client, tasty, zip-archive, Glob.
    * Require skylighting >= 0.7.5, adding support for sml, J,
      typescript.
    * Tests:  Cleaned up `findPandoc` in `Tests.Helpers`, so it
      works well with cabal v2.
    * INSTALL.md:
      + Use button for installer links (John MacFarlane, Mauro Bieg,
      [#5167]).
      + Fix links and bump required stack version (max).
      + Improve installation notes on associated software (Andrew
      Dunning). Includes explanation of how to install related tools
      with package managers (since the method of installing
      `rsvg-convert` is not obvious).
    * doc/org.md: improve documentation of org features (Albert
      Krewinkel).
    * doc/lua-filters.md:  use 3rd level headers for module fields.
    * MANUAL:
      + Clarify automatic identifiers (#5201). We remove
      non-alphanumerics. This includes, e.g., emojis.
      + Fix example for Div with id (Geoffrey Ely).
      + Update list of LaTeX packages used.
      + Make it clear that `hard_line_breaks` works in `gfm` (see #5195).
      + Mention `raw_attribute` in documentation for `raw_html` and
      `raw_tex` (#5240, thanks to @eiro).
      + Clarify that `$sep$` must come right before `$endfor$` in templates
      (#5243, Lev Givon).
      + Document metadata support for docx, odt, pptx writers (Agustín
      Martín Barbero).
      + Reorganize template variables (#5249, Andrew Dunning).
      Add additional headings to categorize variables, and
      alphabetize when there is large number; add more examples.
      + Document `date-meta` template variable (#5260, Tristan Stenner).
    * trypandoc: Fix CSS and viewport.
* Mon Jan 14 2019 [email protected]
  - Patch build to cope with with recent versions of 'http-client'.
* Fri Jan 11 2019 [email protected]
  - Increase required memory in _constraints to avoid OOM failures
* Wed Dec 05 2018 [email protected]
  - Update Cabal build instructions to support zip-archive 0.4.
* Tue Nov 27 2018 [email protected]
  - Update pandoc to version 2.5.
    * Text.Pandoc.App: split into several unexported submodules (Albert
      Krewinkel):  Text.Pandoc.App.FormatHeuristics,
      Text.Pandoc.App.Opt, Text.Pandoc.App.CommandLineOptions,
      Text.Pandoc.App.OutputSettings.  This is motivated partly by the
      desire to reduce recompilations when something is modified,
      since App previously depended on virtually every other module.
    * Text.Pandoc.Extensions
      + Semantically, `gfm_auto_identifiers` is now a modifier of
      `auto_identifiers`; for identifiers to be set, `auto_identifiers` must
      be turned on, and then the type of identifier produced depends on
      `gfm_auto_identifiers` and `ascii_identifiers` are set. Accordingly,
      `auto_identifiers` is now added to `githubMarkdownExtensions` (#5057).
      + Remove `ascii_identifiers` from `githubMarkdownExtensions`.
      GitHub doesn't seem to strip non-ascii characters any more.
    * Text.Pandoc.Lua.Module.Utils (Albert Krewinkel)
      + Test AST object equality via Haskell (#5092).  Equality of Lua
      objects representing pandoc AST elements is tested by unmarshalling
      the objects and comparing the result in Haskell.
      A new function `equals` which performs this test has been added to the
      `pandoc.utils` module.
      + Improve stringify.  Meta value strings (MetaString)
      and booleans (MetaBool) are now converted to the literal string and the
      lowercase boolean name, respectively. Previously, all values of these
      types were converted to the empty string.
    * Text.Pandoc.Parsing: Remove Functor and Applicative constraints where Monad
      already exists (Alexander Krotov).
    * Text.Pandoc.Pretty: Don't render BreakingSpace at end of line
      or beginning of line (#5050).
    * Text.Pandoc.Readers.Markdown
      + Fix parsing of citations, quotes, and underline emphasis
      after symbols.  Starting with pandoc 2.4, citations, quoted inlines,
      and underline emphasis were no longer recognized after certain
      symbols, like parentheses (#5099, #5053).
      + In pandoc 2.4, a soft break after an abbreviation would be
      relocated before it to allow for insertion of a nonbreaking
      space after the abbreviation. This behavior is here reverted.
      A soft break after an abbreviation will remain, and no nonbreaking
      space will be added. Those who care about this issue should take care not
      to end lines with an abbreviation, or to insert nonbreaking spaces
      manually.
    * Text.Pandoc.Readers.FB2: Do not throw error for unknown elements in
      `<body>` (Alexander Krotov).  Some libraries include custom elements
      in their FB2 files.
    * Text.Pandoc.Readers.HTML
      + Allow `tfoot` before body rows (#5079).
      + Parse `<small>` as a Span with class "small" (#5080).
      + Allow thead containing a row with `td` rather than `th` (#5014).
    * Text.Pandoc.Readers.LaTeX
      + Cleaned up handling of dimension arguments.  Allow decimal points,
      preceding space.
      + Don't allow arguments for verbatim, etc.
      + Allow space before bracketed options.
      + Allow optional arguments after `\\` in tables.
      + Improve parsing of `\tiny`, `\scriptsize`, etc.  Parse as raw,
      but know that these font changing commands take no arguments.
    * Text.Pandoc.Readers.Muse
      + Trim whitespace before parsing grid table cells (Alexander Krotov).
      + Add grid tables support (Alexander Krotov).
    * Text.Pandoc.Shared
      + For bibliography match Div with id `refs`, not class `references`.
      This was a mismatch between pandoc's docx, epub, latex, and markdown
      writers and the behavior of pandoc-citeproc, which actually looks for a
      div with id `refs` rather than one with class `references`.
      + Exactly match GitHub's identifier generating algorithm (#5057).
      + Add parameter for `Extensions` to `uniqueIdent` and
      `inlineListToIdentifier` (#5057).  [API change]
      This allows these functions to be sensitive to the settings of
      `Ext_gfm_auto_identifiers` and `Ext_ascii_identifiers`, and allows us to
      use `uniqueIdent` in the CommonMark reader, replacing custom code.  It
      also means that `gfm_auto_identifiers` can now be used in all formats.
    * Text.Pandoc.Writers.AsciiDoc
      + Use `.`+ as list markers to support nested ordered lists (#5087).
      + Support list number styles (#5089).
      + Render Spans using `[#id .class]#contents#` (#5080).
    * Text.Pandoc.Writers.CommonMark
      + Respect `--ascii` (#5043, quasicomputational).
      + Make sure `--ascii` affects quotes, super/subscript.
    * Text.Pandoc.Writers.Docx
      + Fix bookmarks to headers with long titles (#5091).
      Word has a 40 character limit for bookmark names.  In addition, bookmarks
      must begin with a letter.  Since pandoc's auto-generated identifiers may
      not respect these constraints, some internal links did not work.  With
      this change, pandoc uses a bookmark name based on the SHA1 hash of the
      identifier when the identifier isn't a legal bookmark name.
      + Add bookmarks to code blocks (Nikolay Yakimov).
      + Add bookmarks to images (Nikolay Yakimov).
      + Refactor common bookmark creation code into a function (Nikolay Yakimov).
    * Text.Pandoc.Writers.EPUB: Handle calibre metadata (#5098).
      Nodes of the form
      <meta name="calibre:series" content="Classics on War and Politics"/>
      are now included from an epub XML metadata file.  You can also include
      this information in your YAML metadata, like so:
      calibre:
      series: Classics on War and Policitics
      In addition, ibooks-specific metadata can now be included via an XML
      file. (Previously, it could only be included via YAML metadata, see
      [#2693].)
    * Text.Pandoc.Writers.HTML: Use plain `"` instead of `&quot;` outside of
      attributes.
    * Text.Pandoc.Writers.ICML: Consolidate adjacent strings, inc. spaces.
      This avoids splitting up the output unnecessarily into separate elements.
    * Text.Pandoc.Writers.LaTeX: Don't emit `[<+->]` unless beamer output, even
      if `writerIncremental` is True (#5072).
    * Text.Pandoc.Writers.Muse (Alexander Krotov).
      + Output tables as grid tables if they have multi-line cells.
      + Indent simple tables only on the top level.
      + Output tables with one column as grid tables.
      + Add support for `--reference-location`.
      + Internal improvements.
    * Text.Pandoc.Writers.OpenDocument: Fix list indentation (Nils Carlson,
      [#5095]).  This was a regression in pandoc 2.4.
    * Text.Pandoc.Writers.RTF: Fix warnings for skipped raw inlines.
    * Text.Pandoc.Writers.Texinfo: Add blank line before `@menu` section (#5055).
    * Text.Pandoc.XML: in `toHtml5Entities`, prefer shorter entities
      when there are several choices for a particular character.
    * data/abbreviations
      + Add additional abbreviations (Andrew Dunning)
      Many of these borrowed from the Chicago Manual of Style 10.42,
      'Scholarly abbreviations'.
    * Templates
      + Asciidoc template:  add :lang: to title header is lang is set in
      metadata (#5088).
    * pandoc.cabal: Add cabal flag `derive_json_via_th` (Albert Krewinkel)
      Disabling the flag will cause derivation of ToJSON and FromJSON
      instances via GHC Generics instead of Template Haskell. The flag is
      enabled by default, as deriving via Generics can be slow (see #4083).
    * trypandoc:
      + Tweaked drop-down lists.
      + Put link to site in footer.
      + Preselect output format.
      + Update on change of in or out format.
      + Add man input format.
    * MANUAL.txt:
      + Fix outdated description of latex_macros extension.
      + Clarified placement of bibliography.
      + Added "A note on security."
      + Fix note on curly brace syntx for locators.
      + Document new explicit syntax for citeproc locators.
      + Remove confusing cross-links for some extensions.
      + Don't put pandoc in code ticks in heading.
      + Document that `--ascii` works for gfm and commonmark too.
      + Add `man` to `--from` options.
    * doc/customizing-pandoc.md: various improvements (Mauro Bieg).
* Mon Nov 05 2018 [email protected]
  - Update pandoc to version 2.4.
    pandoc (2.4)
      [new features]
    * New input format `man` (Yan Pashkovsky, John MacFarlane).
      [behavior changes]
    * `--ascii` is now implemented in the writers, not in Text.Pandoc.App,
      via the new `writerPreferAscii` field in `WriterOptions`.
      Now the `write*` functions for Docbook, HTML, ICML, JATS, LaTeX,
      Ms, Markdown, and OPML are sensitive to `writerPreferAscii`.
      Previously the to-ascii translation was done in Text.Pandoc.App,
      and thus not available to those using the writer functions
      directly.
    * `--ascii` now works with Markdown output.  HTML5 character reference
      entities are used.
    * `--ascii` now works with LaTeX output. 100% ASCII output can't be
      guaranteed, but the writer will use commands like `\"{a}` and `\l`
      whenever possible, to avoid emiting a non-ASCII character.
    * For HTML5 output, `--ascii` now uses HTML5 character reference
      entities rather than numerical entities.
    * Improved detection of format based on extension (in Text.Pandoc.App).
      We now ensure that if someone tries to convert a file for a
      format that has a pandoc writer but not a reader, it won't just
      default to markdown.
    * Add viz. to abbreviations file (#5007, Nick Fleisher).
    * AsciiDoc writer:  always use single-line section headers,
      instead of the old underline style (#5038).  Previously the single-line
      style would be used if `--atx-headers` was specified, but
      now it is always used.
    * RST writer: Use simple tables when possible (#4750).
    * CommonMark (and gfm) writer: Add plain text fallbacks. (#4528,
      quasicomputational). Previously, the writer would unconditionally
      emit HTML output for subscripts, superscripts, strikeouts (if the
      strikeout extension is disabled) and small caps, even with
      `raw_html` disabled. Now there are plain-text (and, where
      possible, fancy Unicode) fallbacks for all of these corresponding
      (mostly) to the Markdown fallbacks, and the HTML output is only
      used when `raw_html` is enabled.
    * Powerpoint writer: support raw openxml (Jesse Rosenthal, #4976).
      This allows raw openxml blocks and inlines to be used in the pptx
      writer. Caveats: (1) It's up to the user to write
      well-formed openxml. The chances for corruption, especially with
      such a brittle format as pptx, is high. (2) Because of
      the tricky way that blocks map onto shapes, if you are using
      a raw block, it should be the only block on a slide
      (otherwise other text might end up overlapping it). (3) The
      pptx ooxml namespace abbreviations are different from the
      docx ooxml namespaces. Again, it's up to the user to get it
      right. Unzipped document and ooxml specification should be
      consulted.
    * With `--katex` in HTML formats, do not use the autorenderer (#4946).
      We no longer surround formulas with `\(..\)` or `\[..\]`. Instead,
      we tell katex to convert the contents of span elements with
      class "math". Since math has already been identified, this
      avoids wasted time parsing for LaTeX delimiters. Note, however,
      that this may yield unexpected results if you have span elements
      with class "math" that don't contain LaTeX math.
      Also, use latest version of KaTeX by default (0.9.0).
    * The man writer now produces ASCII-only output, using groff escapes,
      for portability.
    * ODT writer:
      + Add title, author and date to metadata; any remaining
      metadata fields are added as `meta:user-defined` tags.
      + Implement table caption numbering (#4949, Nils Carlson).
      Captioned tables are numbered and labeled with format "Table 1:
      caption", where "Table" is replaced by a translation, depending
      on the value of `lang` in metadata. Uncaptioned tables are not
      enumerated.
      + OpenDocument writer: Implement figure numbering in captions (#4944,
      Nils Carlson). Figure captions are now numbered 1, 2, 3, ...
      The format in the caption is "Figure 1: caption" and so on
      (where "Figure" is replaced by a translation, depending on the
      value of `lang` in the metadata). Captioned figures are numbered
      consecutively and uncaptioned figures are not enumerated. This
      is necessary in order for LibreOffice to generate an
      Illustration Index (Table of Figures) for included figures.
    * RST reader: Pass through fields in unknown directives as div attributes
      (#4715). Support `class` and `name` attributes for all directives.
    * Org reader: Add partial support for `#+EXCLUDE_TAGS` option. (#4284,
      Brian Leung). Headers with the corresponding tags should not
      appear in the output.
    * Log warnings about missing title attributes now include a
      suggestion about how to fix the problem (#4909).
    * Lua filter changes (Albert Krewinkel):
      + Report traceback when an error occurs. A proper Lua traceback is
      added if either loading of a file or execution of a filter
      function fails. This should be of help to authors of Lua filters
      who need to debug their code.
      + Allow access to pandoc state (#5015). Lua filters and custom
      writers now have read-only access to most fields of pandoc's
      internal state via the global variable `PANDOC_STATE`.
      + Push ListAttributes via constructor (Albert Krewinkel).
      This ensures that ListAttributes, as present in OrderedList elements,
      have additional accessors (viz. `start`, `style`, and `delimiter`).
      + Rename ReaderOptions fields, use snake_case. Snake case is used
      in most variable names, using camelCase for these fields was an
      oversight. A metatable is added to ensure that the old field
      names remain functional.
      + Iterate over AST element fields when using `pairs`. This makes
      it possible to iterate over all ield names of an AST element by
      using a generic `for` loop with pairs`:
      for field_name, field_content in pairs(element) do
      ...
      end
      Raw table fields of AST elements should be considered an
      implementation detail and might change in the future. Accessing
      element properties should always happen through the fields
      listed in the Lua filter docs.
      Note that the iterator currently excludes the `t`/`tag` field.
      + Ensure that MetaList elements behave like Lists. Methods usable
      on Lists can also be used on MetaList objects.
      + Fix MetaList constructor (Albert Krewinkel). Passing a MetaList
      object to the constructor `pandoc.MetaList` now returns the
      passed list as a MetaList. This is consistent with the
      constructor behavior when passed an (untagged) list.
    * Custom writers: Custom writers have access to the global variable
      `PANDOC_DOCUMENT`(Albert Krewinkel, #4957). The variable contains
      a userdata wrapper around the full pandoc AST and exposes two
      fields, `meta` and `blocks`. The field content is only
      marshaled on-demand, performance of scripts not accessing the
      fields remains unaffected.
      [API changes]
    * Text.Pandoc.Options: add `writerPreferAscii` to `WriterOptions`.
    * Text.Pandoc.Shared:
      + Export `splitSentences`. This was previously duplicated in the Man and
      Ms writers.
      + Add `ToString` typeclass (Alexander Krotov).
    * New exported module Text.Pandoc.Filter (Albert Krewinkel).
    * Text.Pandoc.Parsing
      + Generalize `gridTableWith` to any `Char` Stream (Alexander Krotov).
      + Generalize `readWithM` from `[Char]` to any `Char` Stream
      that is a `ToString` instance (Alexander Krotov).
    * New exposed module Text.Pandoc.Filter (Albert Krewinkel).
    * Text.Pandoc.XML: add `toHtml5Entities`.
    * New exported module Text.Pandoc.Readers.Man (Yan Pashkovsky, John
      MacFarlane).
    * Text.Pandoc.Writers.Shared
      + Add exported functions `toSuperscript` and
      `toSubscript` (quasicomputational, #4528).
      + Remove exported functions `metaValueToInlines`,
      `metaValueToString`. Add new exported functions
      `lookupMetaBool`, `lookupMetaBlocks`, `lookupMetaInlines`,
      `lookupMetaString`. Use these whenever possible for uniformity
      in writers (Mauro Bieg, #4907). (Note that
      removed function `metaValueToInlines` was in previous
      released versions.)
      + Add `metaValueToString`.
    * Text.Pandoc.Lua
      + Expose more useful internals (Albert Krewinkel):
    - `runFilterFile` to run a Lua filter from file;
    - data type `Global` and its constructors; and
    - `setGlobals` to add globals to a Lua environment.
      This module also contains `Pushable` and `Peekable` instances
      required to get pandoc's data types to and from Lua. Low-level
      Lua operation remain hidden in Text.Pandoc.Lua.
      + Rename `runPandocLua` to `runLua` (Albert Krewinkel).
      + Remove `runLuaFilter`, merging this into Text.Pandoc.Filter.Lua's
      `apply` (Albert Krewinkel).
      [bug fixes and under-the-hood improvements]
    * Text.Pandoc.Parsing
      + Make `uri` accept any stream with Char tokens (Alexander Krotov).
      + Rewrite `uri` without `withRaw` (Alexander Krotov).
      + Generalize `parseFromString` and `parseFromString'` to any
      streams with Char token (Alexander Krotov)
      + Rewrite `nonspaceChar` using `noneOf` (Alexander Krotov)
    * Text.Pandoc.Shared: Reimplement `mapLeft` using `Bifunctor.first`
      (Alexander Krotov).
    * Text.Pandoc.Pretty: Simplify `Text.Pandoc.Pretty.offset`
      (Alexander Krotov).
    * Text.Pandoc.App
      + Work around HXT limitation for --syntax-definition with windows
      drive (#4836).
      + Always preserve tabs for man format. We need it for tables.
      + Split command line parsing code into a separate unexported
      module, Text.Pandoc.App.CommandLineOptions (Albert Krewinkel).
    * Text.Pandoc.Readers.Roff: new unexported module for tokenizing
      roff documents.
    * New unexported module Text.Pandoc.RoffChar, provided character
      escape tables for roff formats.
    * Text.Pandoc.Readers.HTML: Fix `htmlTag` and `isInlineTag` to
      accept processing instructions (#3123, regression since 2.0).
    * Text.Pandoc.Readers.JATS: Use `foldl'` instead of `maximum` to
      account for empty lists (Alexander Krotov).
    * Text.Pandoc.Readers.RST: Don't allow single-dash separator in
      headerless table (#4382).
    * Text.Pandoc.Readers.Org: Parse empty argument array in inline src
      blocks (Brian Leung).
    * Text.Pandoc.Readers.Vimwiki:
      + Get rid of `F`, `runF` and `stateMeta'` in favor of `stateMeta`
      (Alexander Krotov).
      + Parse `Text` without converting to `[Char]` (Alexander Krotov).
    * Text.Pandoc.Readers.Creole: Parse `Text` without converting to
      `[Char]` (Alexander Krotov).
    * Text.Pandoc.Readers.LaTeX
      + Allow space at end of math after `\` (#5010).
      + Add support for `nolinkurl` command (#4992, Brian Leung).
      + Simplified type on `doMacros'`.
      + Tokenize before pulling tokens, rather than after (#4408). This
      has some performance penalty but is more reliable.
      + Make macroDef polymorphic and allow in inline context.
      Otherwise we can't parse something like `\lowercase{\def\x{Foo}}`.
      I have actually seen tex like this in the wild.
      + Improved parsing of `\def`, `\let`. We now correctly parse:
      ```
      \def\bar{hello}
      \let\fooi\bar
      \def\fooii{\bar}
      \fooi +\fooii
      \def\bar{goodbye}
      \fooi +\fooii
      ```
      + Improve parsing of `\def` argspec.
      + Skip `\PackageError` commands (see #4408).
      + Fix bugs omitting raw tex (#4527). The default is `-raw_tex`,
      so no raw tex should result unless we explicitly say `+raw_tex`.
      Previously some raw commands did make it through.
      + Moved `isArgTok` to Text.Pandoc.Readers.LaTeX.Parsing.
      + Moved `babelLangToBCP`, `polyglossiaLangToBCP` to new module,
      Text.Pandoc.Readers.LaTeX.Lang (unexported).
      + Simplified accent code using unicode-transforms.
      New dependency on unicode-transforms package for normalization.
      + Allow verbatim blocks ending with blank lines (#4624).
      + Support `breq` math environments: `dmath`, `dgroup`, `darray`.
      This collects some of the general-purpose code from the LaTeX reader,
      with the aim of making the module smaller.
    * Text.Pandoc.Readers.Markdown
      + Fix awkward soft break movements before abbreviations (#4635).
      + Add updateStrPos in a couple places where needed.
    * Text.Pandoc.Readers.Docx: Trigger bold/italic with bCs, iCs
      (#4947). These are variants for "complex scripts" like Arabic
      and are now treated just like b, i (bold, italic).
    * Text.Pandoc.Readers.Muse (Alexander Krotov)
      + Try to parse lists before trying to parse table.
      This ensures that tables inside lists are parsed correctly.
      + Forbid whitespace after opening and before closing markup
      elements.
      + Parse page breaks.
      + Simplify `museToPandocTable` to get rid of partial functions.
      + Allow footnotes to start with empty line.
      + Make sure that the whole text is parsed.
      + Allow empty headers. Previously empty headers caused parser to
      terminate without parsing the rest of the document.
      + Allow examples to be indented with tabs.
      + Remove indentation from examples indicated by `{{{` and `}}}`.
      + Fix parsing of empty cells.
      + Various changes to internals.
      + Rewrite some parsers in applicative style.
      + Avoid tagsoup dependency.
      + Allow table caption to contain `+`.
    * Text.Pandoc.Writers.LaTeX
      + Add newline if math ends in a comment (#4880). This prevents the
      closing delimiter from being swalled up in the comment.
      + With `--listings`, don't pass through org-babel attributes (#4889).
      + With `--biblatex`, use `\autocite` when possible (#4960).
      `\autocites{a1}{a2}{a3}` will not collapse the entries. So, if
      we don't have prefixes and suffixes, we use instead
      `\autocite{a1;a2;a3}`.
      + Fix description lists contining highlighted code (#4662).
    * Text.Pandoc.Writers.Man
      + Don't wrap `.SH` and `.SS` lines (#5019).
      + Avoid unnecessary `.RS`/`.RE` pair in definition lists with
      one paragraph definitions.
      + Moved common groff functions to Text.Pandoc.Writers.Groff.
    * Fix strong/code combination on man (should be `\f[CB]` not
      `\f[BC]`, see #4973).
      + Man writer: use `\f[R]` instead of `\f[]` to reset font
      (Alexander Krotov, #4973).
      + Move `splitSentences` to Text.Pandoc.Shared.
    * Text.Pandoc.Writers.Docx
      + Add framework for custom properties (#3034). So far, we don't
      actually write any custom properties, but we have the
      infrastructure to add this.
      + Handle tables in table cells (#4953). Although this is not
      documented in the spec, some versions of Word require a `w:p`
      element inside every table cell. Thus, we add one when the
      contents of a cell do not already include one (e.g. when a table
      cell contains a table).
    * Text.Pandoc.Writers.AsciiDoc:  Prevent illegal nestings.
      Adjust header levels so that n+1 level headers are only
      found under n level headers, and the top level is 1.
    * Text.Pandoc.Writers.OpenDocument: Improve bullet/numbering
      alignment (#4385). This change eliminates the large gap we used
      to have between bullet and text, and also ensures that numbers
      in numbered lists will be right-aligned.
    * Text.Pandoc.Writers.ZimWiki
      + Number ordered list items sequentially, rather than always
      with 1 (#4962).
      + Remove extra indentation on lists (#4963).
    * Text.Pandoc.Writers.EPUB: Use metadata field `css` instead of
      `stylesheet` (Mauro Bieg, #4990).
    * Text.Pandoc.Writers.Markdown: Ensure blank between raw block and
      normal content (#4629). Otherwise a raw block can prevent a
      paragraph from being recognized as such.
    * Text.Pandoc.Writers.Ms
      + Removed old `escapeBar`. We don't need this now that we use
      `@` for math delim.
      + Moved common code to Text.Pandoc.Writers.Roff and to
      Text.Pandoc.RoffChar.
      + Move `splitSentences` to Text.Pandoc.Shared (to avoid duplication
      with the man writer).
    * Text.Pandoc.Writers.Muse (Alexander Krotov).
      + Add support for grid tables.
      + Fix Muse writer style.
      + Use `length` instead of `realLength` to calculate definition
      indentation. Muse parsers don't take character width into
      account when calculating indentation.
      + Do not insert newline before lists.
      + Use lightweight markup after `</em>` tag.
    * New unexported module Text.Pandoc.Writers.Roff, providing functions
      useful for all roff format writers (man, ms).
    * Text.Pandoc.Lua
      + Move globals handling to separate module Text.Pandoc.Lua.Global
      (Albert Krewinkel).
      + Lua filter internals: push Shared.Element as userdata (Albert
      Krewinkel). Hierarchical Elements were pushed to Lua as plain
      tables. This is simple, but has the disadvantage that marshaling
      is eager: all child elements will be marshaled as part of the
      object. Using a Lua userdata object instead allows lazy access
      to fields, causing content marshaling just (but also each time)
      when a field is accessed. Filters which do not traverse the full
      element contents tree become faster as a result.
      [default template changes]
    * LaTeX template:
      + Add variable `hyperrefoptions` (#4925, Mathias Walter).
      + Add variable `romanfont`, `romanfontoptions` (#4665, OvidiusCicero).
    * AsciiDoc template: use single-line style for title.
    * revealjs template: Fix typo in the socket.io javascript plugin (#5006,
      Yoan Blanc).
    * Text.Pandoc.Lua.Util: add missing docstring to `defineHowTo`
      (Albert Krewinkel).
    * data/pandoc.lua: add datatype ListAttributes (Albert Krewinkel)
    * data/sample.lua: replace custom pipe function with pandoc.utils.pipe
      (Albert Krewinkel).
      [documentation improvements]
    * INSTALL.md
      + Add chromeos install instructions (#4958) (Evan Pratten).
      + Add note about TinyTeX.
    * MANUAL.txt
      + Change `groff` -> `roff`.
      + Implement `--ascii` for Markdown writer.
      + Clarify LaTeX image dimensions output (Mauro Bieg).
    * doc/customizing-pandoc.md: added skeleton (Mauro Bieg, #3288).
    * doc/getting-started.md: Added title to test1.md to avoid warning.
    * doc/lua-filters.md: merge type references into main document,
      fix description of Code.text (Albert Krewinkel).
      [build infrastructure improvements]
    * Makefile
      + Makefile: added quick-cabal, full-cabal targets.
      + Make .msi download targets insensitive to order of appveyor builds.
    * Update benchmarks for ghc 8.6.1.
    * pandoc.cabal:
      + Enable more compiler warnings (Albert Krewinkel).
      + Make base lower bound 4.8.
      + Bump upper bound for QuickCheck.
      + Bump upper bound for binary.
      + Updated version bounds for containers and haddock-library (#4974).
      + Added docx/docPropos/custom.xml to cabal data-files.
      + Require skylighting 0.7.4 (#4920).
      + New dependency on unicode-transforms package for normalization.
    * Improved .travis.yml testing and test with GHC 8.6.1 (Albert Krewinkel).
    * Added `tools/changelog-helper.sh`.
    * Added test/grofftest.sh for testing the man reader on real man pages.
* Wed Oct 10 2018 [email protected]
  - Update pandoc to version 2.3.1.
    * RST reader:
      + Parse RST inlines containing newlines (#4912, Francesco Occhipinti).
      This eliminates a regression introduced after pandoc 2.1.1, which
      caused inline constructions containing newlines not to be recognized.
      + Fix bug with internal link targets (#4919).  They were gobbling up
      indented content underneath.
    * Markdown reader: distinguish autolinks in the AST.  With this change,
      autolinks are parsed as Links with the `uri` class. (The same is true
      for bare links, if the `autolink_bare_uris` extension is enabled.)
      Email autolinks are parsed as Links with the `email` class.  This
      allows the distinction to be represented in the AST.
    * Org reader:
      + Force inline code blocks to honor export options (Brian Leung).
      + Parse empty argument array in inline src blocks (Brian Leung).
    * Muse reader (Alexander Krotov):
      + Added additional tests.
      + Do not allow code markup to be followed by digit.
      + Remove heading level limit.
      + Simplify `<literal>` tag parsers
      + Parse Text instead of String. Benchmark shows 7% improvement.
      + Get rid of HTML parser dependency.
      + Various code improvements.
    * ConTeXt writer: change `\` to `/` in Windows image paths (#4918).
      We do this in the LaTeX writer, and it avoids problems.
      Note that `/` works as a LaTeX path separator on Windows.
    * LaTeX writer:
      + Add support for multiprenote and multipostnote arguments
      with `--biblatex` (Brian Leung, #4930).  The multiprenotes occur before
      the first prefix of a multicite, and the multipostnotes follow the
      last suffix.
      + Fix a use of `last` that might take empty list.  If you ran with
      `--biblatex` and have an empty document (metadata but no blocks),
      pandoc would previously raise an error because of the use of
      `last` on an empty list.
    * RTF writer: Fix build failure with ghc-8.6.1 caused by missing
      MonadFail instance (Jonas Scholl).
    * ODT Writer: Improve table header row style handling (Nils Carlson).
      This changes the way styles for cells in the header row
      and normal rows are handled in ODT tables.
      Previously a new (but identical) style was generated for
      every table, specifying the style of the cells within the table.
      After this change there are two style definitions for table cells,
      one for the cells in the header row, one for all other cells.
      This doesn't change the actual styles, but makes post-processing
      changes to the table styles much simpler as it is no longer
      necessary to introduce new styles for header rows and there are
      now only two styles where there was previously one per table.
    * HTML writer:
      + Don't add `uri` class to presumed autolinks.  Formerly the `uri`
      class was added to autolinks by the HTML writer, but it had to
      guess what was an autolink and could not distinguish
      `[http://example.com](http://example.com)` from
      `<http://example.com>`.  It also incorrectly recognized
      `[pandoc](pandoc)` as an autolink.  Now the HTML writer
      simply passes through the `uri` attribute if it is present,
      but does not add anything.
      + Avoid adding extra section nestings for revealjs.
      Previously revealjs title slides at level (slidelevel - 1)
      were nested under an extra section element, even when
      the section contained no additional (vertical) content.
      That caused problems for some transition effects.
      + Omit unknown attributes in EPUB2 output.  For example,
      `epub:type` attributes should not be passed through,
      or the epub produced will not validate.
    * JATS writer: remove 'role' attribute on 'bold' and 'sc' elements (#4937).
      The JATS spec does not allow these.
    * Textile writer: don't represent `uri` class explicitly
      for autolinks (#4913).
    * Lua filters (Albert Krewinkel):
      + Cleanup filter execution code.
      + Better error on test failure.
    * HTML, Muse reader tests: reduce time taken by round-trip test.
    * Added cabal.project.
    * MANUAL: `epub:type` is only useful for epub3 (Maura Bieg).
    * Use hslua v1.0.0 (Albert Krewinkel).
    * Fix `translations/ru` to use modern Russian orthography
      (Ivan Trubach).
    * Build Windows binary using ghc 8.6.1 and cabal new-build. This
      fixes issues with segfaults in the 32-bit Windows binaries (#4283).
    * Add `--metadata-file` option (Mauro Bieg, #1960), which allows
      users to specify metadata in a YAML file, regardless of the
      input format (#1960).
    * Text.Pandoc.Writers.Shared: export `isDisplayMath` (API change).
    * Text.Pandoc.Readers.Markdown: export `yamlToMeta` (API change,
      Mauro Bieg).
    * Text.Pandoc.Readers.LaTeX.Types:
      + New type `ArgSpec` (API change).
      + Second parameter of `Macro` constructor is now `[ArgSpec]` instead of
      `Int` (API change).
    * Markdown reader:
      + Use `tex` instead of `latex` for raw tex-ish content. We can't
      always tell if it's LaTeX, ConTeXt, or plain TeX. Better just to
      use `tex` always. Note that if `context` or `latex` specifically
      is desired, you can still force that in a markdown document by
      using the raw attribute. Note that this change may affect some
      filters, if they assume that raw tex parsed by the Markdown reader
      will be RawBlock (Format `latex`). In most cases it should be
      trivial to modify the filters to accept `tex` as well.
      + Refactor and reorganize YAML code (Mauro Bieg).
      + Make `example_lists` work for interrupted lists
      without `startnum` (#4908).
    * HTML reader:
      + Parse `<script type="math/tex` tags as math (#4877).
      These are used by MathJax in some configurations.
      + Extract spaces inside links instead of trimming them
      (Alexander Krotov, #4845).
      + Added round-trip tests (Alexander Krotov).
      + Make parsing sensitive to the `raw_tex` extension (#1126). This now
      allows raw LaTeX environments, `\ref`, and `\eqref` to be parsed
      (which is helpful for translation HTML documents using MathJaX).
    * Org reader (Albert Krewinkel):
      + Respect export option `p` for planning info.  Inclusion of planning info
      (`*DEADLINE*`, `*SCHEDULED*`, and `*CLOSED*`) can be controlled via the
      `p` export option: setting the option to `t` will add all planning
      information in a *Plain* block below the respective headline.
      + Org reader internals: don't rely on RecordWildCards and ViewPatterns
      ghc extensions.
      + Strip planning info from output.  Planning info is parsed, but not
      included in the output (as is the default with Emacs Org-mode, #4867).
    * LaTeX reader:
      + Split some general-purpose definitions into a separate, unexported
      module, Text.Pandoc.Readers.LaTeX.Parsing.  This is to avoid
      out-of-memory errors compiling the LaTeX reader.
      + Handle parameter patterns for `\def` (#4768, #4771).
      For example:  `\def\foo#1[#2]{#1 and #2}`.
      + Allow `%` characters in URLs. This affects `\href` and `\url` (#4832).
      + Fixed parsing of `\texorpdfstring`. We were returning the wrong
      argument as the content.
      + Support `blockcquote`, `foreignblockquote`, `foreigncblockquote`,
      `hyphenblockquote`, `hyphencblockquote`, `enquote*`, `foreignquote`,
      `hyphenquote` from `csquotes` (#4848). Note that `foreignquote`
      will be parsed as a regular Quoted inline (not using the quotes
      appropriate to the foreign language).
      + Support more text-mode accents (#4652). Add support for `\|`, `\b`, `\G`,
      `\h`, `\d`, `\f`, `\r`, `\t`, `\U`, `\i`, `\j`, `\newtie`,
      `\textcircled`. Also fall back to combining characters when composed
      characters are not available.
      + Resolve `\ref` for figure numbers.
      + Support `mintinline` (#4365, Marc Schreiber).
      + Fix siunitx unit commands so they are only recognized in
      siunitx contexts (#4842). For example, `\l` outside of an
      siunitx context should be l-slash, not l (for liter).
      + Fix double `unnumbered` class (#4838). The `unnumbered` class
      was being included twice for starred sections.
    * RST reader: Don't skip link definitions after comments (#4860).
    * Muse reader (Alexander Krotov):
      + Close the `</quote>` in indented tag test.
      There is already a separate test for unclosed `</quote>`.
      + Autonumber sections in the correct order.  Parsing now stops
      at each section header to ensure the header is registered before
      parsing of the next section starts.
      + Move duplicate code into `headingStart` function.
      + Allow newline after opening `*` or `**`.
      + Don't allow digits after closing marker in lightweight markup
      This change makes reader more compatible with Emacs Muse.
      + Parse `<verse>` tag in one pass instead of using
      `parseFromString`. This change makes it possible to have
      verbatim `</verse>` tag inside verse.
    * ODT reader:  deal gracefully with missing `<office:font-face-decls/>`
      (#4336). This allows pandoc to parse ODT document produced by KDE's
      Calligra.
    * Muse writer (Alexander Krotov):
      + Output headers without asterisks if not on the top level.
      + Never wrap definition list terms.
      + Set `envInsideBlock = True` when rendering notes.
      + Use `""` instead of `[]` for empty String.
      + Check for whitespace in the beginning and end of Str's.
      + Escape `-`, `;` and `>` in the beginning of strings.
      + Escape list markers in the beginning of notes.
      + Normalize inline list before testing if tags should be used.
      + Use tags instead of lightweight markup for empty strings.
      + Use lightweight markup when possible.
      + Escape empty strings.  This guarantees that `conditionalEscapeString`
      never returns empty string.
      + Wrap conditionalEscapeString result into `Muse` type.
      This removes the need to pass `envInsideLinkDescription` to it.
      + Separate `shouldEscapeString` function.
      + Simplify inline list rendering.
      + Replace newlines in strings with spaces.
    * Docx writer:
      + Add MetaString case for abstract, subtitle (#4900, Mauro Bieg).
      + Properly handle display math in spans (#4826). This isn't a
      complete solution, since other nestings of display math may still
      cause problems, but it should work for what is by far the most
      common case.
    * HTML writer:
      + Always output `<dt>` element, even if it is empty (#4883,
      Alexander Krotov).
      + Don't prefix `epub:` attributes with `data-`.
    * Org writer: Don't escape literal `_`, `^` (#4882). Org doesn't
      recognize these escapes.
    * ODT writer: Fix percentage image scaling (#4881, Nils Carlson).
      Image scaling was broken when a width was set to a percentage.
    * EPUB writer: set `epub:type` on body element in each chapter,
      depending on the `epub:type` of the first section (#4823). This
      only affects epub3. See
      http://www.idpf.org/epub/profiles/edu/structure/#h.l0bzsloklt10
    * FB2 writer: put `coverpage` element between title and date rather than in
      `document-info` element (#4854).
    * Markdown writer: Escape `~` if strikeout extension enabled (#4840).
    * Haddock writer: Use proper format for latex math in haddock (#4571, Joe
      Hermaszewski). Inline math in `\(..\)`, display math in `\[..\]`,
      tex is now used. Previously we'd "fake it with unicode" and fall
      back to tex when that didn't work. But newer haddock versions
      support latex math.
    * TEI writer:
      + Ensure that title element is always present, even if empty (#4839).
      + Put author tags in the template, rather than adding them in
      the writer (#4839).
    * LaTeX writer/template: be sensitive to `filecolor` variable (#4822).
      `linkcolor` only affects internal links, and `urlcolor` only
      affects linked URLs.  For external links, the option to use is
      `filecolor`.
    * ConTeXt writer: output raw `tex` blocks as well as `context` (#969).
    * RST writer:
      + Use `.. raw:: latex` for `tex` content.
      + Use `.. container` for generic Divs, instead of raw HTML.
      + Render Divs with admonition classes as admonitions (#4833).
      Also omit Div with class `admonition-title`. These are generated
      by the RST reader and should be omitted on round-trip.
    * Text.Pandoc.PDF: fix message printed when rsvg-convert is not available
      (#4855, Antonio Terceiro).
    * HTML5 template: add the `title-block-header` identifier to the
      `header` element, to make it easier to style precisely (#4767,
      J. B. Rainsberger).
    * OpenDocument template: Remove unnecessary indenting of TOC title (#4798,
      José de Mattos Neto).
    * latex template: Add support for $toc-title$ to LaTeX (and PDF)
      (#4853, Wandmalfarbe).
    * TEI template: improve `publicationStmt`. Add support for
      `publisher`, `address`, `pubPlace`, and `date` variables.
    * beamer template: Support "toc-title" (#4835, Cyril Roelandt).
    * Text.Pandoc.Extensions: Fix haddock on `Ext_footnotes` (Chris Martin).
    * Lua: cleanup Lua utils, remove unused functions (Albert Krewinkel).
    * MANUAL.txt:
      + Clarify that `--biblatex/--natbib` don't work directly for PDF
      (#4904).
      + Document `epub:type` attribute (Mauro Bieg, #4901)
      + Clarify when `--resource-path` has an effect.
      + More detail on customization in syntax highlighting section.
      + Document encoding issue with `--listings` (#4871, Damien Clochard).
      + Remove docs on removed `--katex-stylesheet` (Mauro Bieg, #4862).
      + Use https for context wiki links (#4910).
    * CONTRIBUTING.md:
      + Link to lua-filters repository (#4874).
      + Fix mistake in REPL instructions for stack. (#4849, Brian Leung).
    * lua-filters.md: add links to filters, and to lua-filters repository
      (#4874).
    * INSTALL.md:
      + Indicate that cabal >= 2.0 is needed.
      + Added chocolatey installation method (#4844, Miodrag Milić).
    * Travis: exclude round-trip tests, except for nightly test which can fail.
    * Use latest texmath, pandoc-citeproc.
    * Use a patched version of foundation until
      https://github.com/haskell-foundation/foundation/pull/503
      is fixed.
    * Clean up appveyor build and Windows package creation.
      We now use 64-bit stack and ghc 8.4.3, lts-12 for the 64-bit build. The
      WiX-based msi is now 64-bit for 64-bit builds (fixing #4795).
    * Remove obsolete RELEASE-CHECKLIST.md.
    * Added additional compiler warnings in Makefile and CI builds.
* Wed Oct 10 2018 [email protected]
  - Add _constraints to avoid OOM errors
* Fri Aug 17 2018 [email protected]
  - Update pandoc to version 2.2.3.2.
    * Markdown reader: Properly handle boolean values in YAML metadata (#4819).
      This fixes a regression in 2.2.3, which cause boolean values to
      be parsed as MetaInlines instead of MetaBool.
      We here record another undocumented (but desirable) change in 2.2.3:
      numerical metadata fields are now parsed as MetaInlines rather than
      MetaString.
    * Markdown reader: Fix parsing of embedded mappings in YAML metadata
      (#4817).  This fixes a regression in 2.2.3 which caused embedded
      mappings (e.g. mappings in sequences) not to work in YAML metadata.
    * RST reader: improve parsing of inline interpreted text roles (#4811).
      + Use a Span with class "title-reference" for the default
    title-reference role.
      + Use `B.text` to split up contents into `Space`s, `SoftBreak`s,
    and `Str`s for `title-reference`.
      + Use Code with class "interpreted-text" instead of Span and Str for
    unknown roles.  (The RST writer has also been modified to round-trip
    this properly.)
      + Disallow blank lines in interpreted text.
      + Backslash-escape now works in interpreted text.
      + Backticks followed by alphanumerics no longer end interpreted text.
      + Remove support for nested inlines (Francesco Occhipinti).
    RST does not allow nested emphasis, links, or other inline
    constructs.  This fixes several bugs (#4581, #4561, #4792).
    * Org reader: fix parsers relying on `parseFromString` (#4784, Albert
      Krewinkel).  Emphasis was not parsed when it followed directly after
      some block types (e.g., lists).
    * Markdown reader: Allow unquoted numbers and booleans as YAML mapping
      keys.  Previously in 2.2.2 you could not do
      ```
    - --
      0: bar
      ...
      ```
      but only
      ```
    - --
      '0': bar
      ...
      ```
      With this change, both forms work.
    * DocBook reader: metadata handling improvements.
      Now we properly parse title and subtitle elements that are direct
      children of book and article (as well as children of bookinfo,
      articleinfo, or info).  We also now use the `subtitle` metadata
      field for subtitles, rather than tacking the subtitle on to the
      title.
    * RST writer:
      + Allow images to be directly nested within links (#4810, Francesco
    Occhipinti).
      + Use `titleblock` instead of `title` variable for title block (#4803,
    Francesco Occhipinti).  `titleblock` contains a properly formatted
    title and subtitle (using top-level headers).  `title` and
    `subtitle` variables are still available and just contain the
    title and subtitle text.  Note that this change will require an
    update to custom rst templates.
      + Render Code with class "interpreted-text" as interpreted text role.
    * MediaWiki writer: Avoid extra blank line in tables with empty cells
      (#4794).  Note that the old output is semantically identical, but the
      new output looks better.
    * Lua Utils module: add function `blocks_to_inlines` (#4799, Albert
      Krewinkel).  Exposes a function converting which flattenes a list of
      blocks into a list of inlines. An example use case would be the
      conversion of Note elements into other inlines.
    * RST template:  use `titleblock` instead of `title`.  Users of
      custom RST templates will want to update this.
    * LaTeX template: Moved some beamer code in default.latex template.
      This change allows beamer themes to change the template and font (as
      Metropolis does) (#4450).
    * Better error message on `-t pdf -o out.pdf` (#1155, Mauro Bieg).
    * Added test case for #4669 to repository.
    * INSTALL.md: Fix broken link for cabal-install (#4806, ChanHoHo).
    * MANUAL.txt:
      + Add beamer info for slide backgrounds (#4802, John Muccigrosso).
      + Clarify when `csquotes` is used in LaTeX writer (#4514).
      + Add `commonmark` to list of output formats where `raw_tex` has an
    effect (see #4527).
* Fri Jul 20 2018 [email protected]
  - Update pandoc to version 2.2.2.1.
    pandoc (2.2.2.1)
    * Fix regression finding templates in user data directory (#4777).
      Under version 2.2.1 and prior pandoc found latex templates in the
      templates directory under the data directory, but this broke in 2.2.2.
    * Fix for bug in parsing `\input` in `rawLaTeXBlock` and
      `rawLaTeXInline` (#4781). (This primarily affects the markdown
      reader, and other readers that accept raw tex.)
      Starting in 2.2.2, everything after an `\input` (or `\include`)
      in a markdown file would be parsed as raw LaTeX.
    * MANUAL:
      + Clarify `gfm` vs `markdown_github` (#4783, Mauro Bieg).
    * Use `keywords` instead of `tags` in YAML metadata example (#4779).
      Unlike `tags`, `keywords` is used in some of the writers
      and default templates.
    * Add missing `rollingLinks` option to revealjs template (#4778,
      Igor Khorlo).
* Wed Jul 18 2018 [email protected]
  - Cosmetic: replace tabs with blanks, strip trailing white space,
    and update copyright headers with spec-cleaner.
* Tue Jul 17 2018 [email protected]
  - Update pandoc to version 2.2.2.
    * Use HsYAML instead of yaml for translations and YAML metadata (#4747).
      yaml wraps a C library; HsYAML is pure Haskell.  Advances #4535.
      Note: HsYAML implements YAML 1.2, in which the valid true
      values are `true`, `True`, `TRUE`.  This means a change in
      the semantics of YAML metadata that could affect users:
      `y`, `yes`, and `on` no longer count as true values.
    * Fix regression: make `--pdf-engine` work with full paths (#4681, Mauro
      Bieg).
    * CommonMark reader: Handle `ascii_identifiers` extension (#4742,
      Anders Waldenborg).  Non-ascii characters were not stripped from
      identifiers even if the `ascii_identifiers` extension was
      enabled (which is is by default for gfm).
    * TikiWiki reader: Improve list parsing (#4722, Mauro Bieg).
      Remove trailing Space from list items.  Parse lists that have no space
      after marker.
    * LaTeX reader:
      + Treat `lilypond` as a verbatim environment (#4725).
      + Parse figure label into Image id (#4700, Mauro Bieg).
      + Beamer: Allow "noframenumbering" option (#4696, Raymond Ehlers).
      + Allow spaces around `\graphicspath` arguments (#4698).
      + Handle includes without surrounding blanklines (#4553).
      In addition, `\input` can now be used in an inline context,
      e.g. to provide part of a paragraph, as it can in LaTeX.
      + In `rawLaTeXBlock`, handle macros that resolve to a
      `\begin` or `\end` (#4667).
      + In `rawLaTeXBlock`, don't expand macros in macro definitions (#4653).
      Note that this only affected LaTeX in markdown.
      + Tighten up reading of beamer overlay specifications (#4669).
      Ideally we'd turn these on only when reading beamer, but currently
      beamer is not distinguished from latex as an input format.
      This commit also activates parsing of overlay specifications
      after commands in general (e.g. `\item`), since they can occur
      in many contexts in beamer.
      + Parse more siunitx unit commands (#4296, #4773).
      + Be more forgiving in key/value option parsing (#4761).
    * Markdown reader:
      + Allow empty code spans, e.g. `` ` ` ``.
      + Emojis are now wrapped in Spans with class `emoji` and
      attribute `data-emoji` (Anders Waldenborg, #4743).
      This allows the writer to handle them in a special way
      (e.g. using a special font, or just rendering the
      emoji name).
    * Muse reader (Alexander Krotov, except where indicated):
      + Get rid of non-exhaustive pattern match warning (Mauro Bieg).
      + Add support for floating images.
      + Add support for images with specified width.
      + Parse image URLs without "guard" and "takeExtension".
      + Split link and image parsing into separate functions.
      + Parse links starting with "URL:" explicitly instead of trying to strip
      "URL:" prefix after parsing.
    * Texinfo writer: Use `@sup` and `@sub` instead of custom macros (#4728,
      Alexander Krotov).
    * Markdown writer: Preserve `implicit_figures` with attributes, even if
      `implicit_attributes` is not set, by rendering in raw HTML (#4677).
    * Markdown and commonmark/github writers now respect the `emoji`
      extension.  So, `-f markdown+emoji -t markdown+emoji` now leaves
      `:smile:` as `:smile:` rather than converting it to a smile
      character.
    * Docx writer: Be sensitive to `toc` in YAML metadata (#4645).
    * ODT/OpenDocument writer: Make internal links work (#4358).
      This adds proper bookmarks to the headers with non-null IDs.
    * EPUB writer: Properly escape pagetitle.  Previously we weren't
      escaping `&` and other XML characters in the pagetitle, so a title
      containing a `&` would be invalid.
    * AsciiDoc Writer: Eescape square brackets at start of line (#4545,
      Mauro Bieg).
    * RST writer:
      + Don't treat 'example' as a syntax name (#4748).
      This fixes conversions from org with example blocks.
      + Support `--number-sections` via the `section-numbering`
      directive in standalone output.
    * reveal.js writer and template: reuse mathjax URL
      provided by the argument to `--mathjax` or the normal pandoc default,
      rather than a hard-coded one in the template (#4701).
    * LaTeX writer:
      + Properly handle footnotes in table captions (#4683).
      Refactored code from figure captions to use in both places.
      + In beamer output, fix single digit column percentage (#4690, Mauro
      Bieg).
    * FB2 writer (Alexander Krotov):
      + Convert Plain to Para in annotation (#2424).
      + Fix order of items in title-info (#2424).
    * Custom writer: fix error message on script failure (Albert Krewinkel).
      Error messages produced by Lua were not displayed by Pandoc.
    * Text.Pandoc.Emoji now exports `emojiToInline`, which returns a Span
      inline containing the emoji character and some attributes with metadata
      (class `emoji`, attribute `data-emoji` with emoji name).  (API change,
      Anders Waldenborg, #4743).
    * Text.Pandoc.PDF:
      + Revert fix for #4484 (only compress images on last run, #4755).
      This will mean some increase in the time it takes to
      produce an image-heavy PDF with xelatex, but it will
      make tables of contents correct, which is more important.
      + Fix logic error in `runTeXProgram`.  We were running the tex program
      one more time than requested.  This should speed up PDF production.
    * Allow `--template` to take a URL as argument.
    * Text.Pandoc.Highlighting: Add missing re-export of `breezeDark`
      highlighting style (#4687, Adrian Sieber, API change).
    * Clarify macOS install in INSTALL.md (#4661).  Make the binary package
      installer the recommended method, and note that on some older versions of
      macOS, homebrew installs from source and takes a lot of disk space
      (#4664, Ian).
    * MANUAL:
      + Clarify EPUB linked media (#4756, Mauro Bieg)
      + Update manual for "true" YAML values.  Now that we're using HsYAML and
      YAML 1.2, the valid true values are `true`, `True`, `TRUE`.  NOTE!
      `y`, `yes`, `on` no longer count as true values.
      + Document `-F` as alias for `--filter` (thanks to Gandalf Saxe).
      + Update manual on how math is rendered in LaTeX.
      + Add proxy description (#4131, Mauro Bieg).
      + Clarify that `--toc` requires `--standalone` (#4703).
      + Update citation styles link (#4699, wiefling).
    * In API docs, clarify how `Ext_east_asian_line_breaks` extension works
      (kaizshang91).  Note that it will not take effect when readers/writers
      are called as libraries (#4674).
    * Improved translations/fr (#4766, lux-lth).
    * Removed inadvertently added `.orig` files from repository (#4648).
    * Remove `network-uri` flag and use 'Network.Socket'.
      This removes a compiler warning.  There is no need for the old
      `network-uri` flag, since network 2.6 was released in 2014.
    * Add stack.lts10.yaml, stack.lts11.yaml.  use lts-12 in stack.yaml.
    * Bump upper bounds for dependent packages.
    * Exclude foundation 0.0.21 for ghc 7.10.  Otherwise cabal gets
      confused because of the way ghc 7.10 is excluded in foundation's
      cabal file.  This can be removed when haskell-foundation/foundation#500
      is fixed.
    * Require cabal-version >= 2.0.  This is needed for haddock-library.
* Tue May 22 2018 [email protected]
  - Avoid use of '[' and ']' characters in %files section entries.
    This allows building for older distributions.
* Mon May 14 2018 [email protected]
  - Update pandoc to version 2.2.1.
    * Restored and undeprecated gladtex for HTML math (#4607).
      + Added `GladTeX` constructor to `Text.Pandoc.Options.HTMLMathMethod`
      [API change, reverts removal in v2.2]
      + Restored and undeprecated `--gladtex` option, removed in v2.2.
    * LaTeX reader:  Handle `$` in `/text{..}` inside math (#4576).
    * Org reader: Fix image filename recognition (Albert Krewinkel).
      Use a function from the filepath library to check whether a string is a
      valid file name.  The custom validity checker that was used before gave
      wrong results (e.g. for absolute file paths on Windows,
      kawabata/ox-pandoc#52).
    * FB2 reader: Replace some errors with warnings (Alexander Krotov).
    * HTML writer:
      + Strip links from headers when creating TOC (#4340).
      Otherwise the TOC entries will not link to the sections.
      + Fix regression with tex math environments in HTML + MathJax (#4639).
    * Muse writer (Alexander Krotov): Add support for left-align and
      right-align classes (#4542).
    * Docx writer: Support underline (#4633).
    * Text.Pandoc.Parsing: Lookahead for non-whitespace after
      `singleQuoteStart` and `doubleQuoteStart` (#4637).
    * `test-pandoc-utils.lua`:  more robust testing on both windows
      and \*nix. Previously the pipe tests were only run if
      `\bin/false` and `/bin/sed` were present, which they aren't
      in default MacOS and Windows systems.  Fixed by using `tr`
      and `false`, which should always be in the path on a \*nix
      system, and `find` and `echo` for Windows.
    * Text.Pandoc.Shared: add `uriPathToPath`.
      This adjusts the path from a file: URI in a way that is sensitive
      to Windows/Linux differences.  Thus, on Windows,
      `/c:/foo` gets interpreted as `c:/foo`, but on Linux,
      `/c:/foo` gets interpreted as `/c:/foo`.  See #4613.
    * Use `uriPathToPath` with file: URIs (#4613).
    * Revert piping HTML to pdf-engine (Mauro Bieg, #4413).  Use a temp
      file as before.
    * Text.Pandoc.Class: Catch IO errors when writing media files
      and issue a warning, rather than an error (Francesco Occhipinti, #4559).
    * Don't lowercase custom writer filename (Alexander Krotov, #4610).
    * MANUAL (Mauro Bieg):
      + Clarify truthiness in template variables (#2281).
      + Clarify pipe table width calculation (#4520).
    * ConTeXt template: New Greek fallback typeface (Pablo Rodríguez, #4405).
      CMU Serif gives better typographic results than the previous
      Greek fallback DejaVu Serif.
    * Make HTML template polyglot (#4606, OvidiusCicero), by making
      `<link rel="stylesheet" href="$css$">` self-closing.
    * Use texmath 0.11, allowing better translation of non-ASCII
      characters in math (#4642).
    * New input format: `fb2` (FictionBook2) (Alexander Krotov).
    * Make `--ascii` work for all XML formats (ICML, OPML, JATS,...),
      and for `ms` and `man`.
    * Remove deprecated `--latexmathml`, `--gladtex`, `--mimetex`, `--jsmath`, `-m`,
      `--asciimathml` options.
    * New module Text.Pandoc.Readers.FB2, exporting readFB2 (Alexander
      Krotov, API change).
    * Markdown reader:
      + Allow empty key-value attributes, like `title=""` (#2944).
      + Handle table w/o following blank line in fenced div (#4560).
      + Remove "fallback" for `doubleQuote` parser.  Previously the
      parser tried to be efficient -- if no end double quote was found,
      it would just return the contents.  But this could backfire in a
      case `**this should "be bold**`, since the fallback would return
      the content `"be bold**` and the closing boldface delimiter
      would never be encountered.
      + Improve computation of the relative width of the last column in a
      multiline table, so we can round-trip tables without constantly
      shrinking the last column.
    * EPUB reader:
      + Fix images with space in file path (#4344).
    * LaTeX reader:
      + Properly resolve section numbers with `\ref` and chapters (#4529).
      + Parse sloppypar environment (#4517, Marc Schreiber).
      + Improve handling of raw LaTeX (for markdown etc.) (#4589, #4594).
      Previously there were some bugs in how macros were handled.
      + Support `\MakeUppercase`, `\MakeLowercase', `\uppercase`, `\lowercase`,
      and also `\MakeTextUppercase` and `\MakeTextLowercase` from textcase
      (#4959).
    * Textile reader:
      + Fixed tables with no body rows (#4513).
      Previously these raised an exception.
    * Mediawiki reader:
      + Improve table parsing (#4508).  This fixes detection of table
      attributes and also handles `!` characters in cells.
    * DocBook reader:
      + Properly handle title in `section` element (#4526).
      Previously we just got `section_title` for `section` (though `sect1`,
      `sect2`, etc. were handled properly).
      + Read tex math as output by asciidoctor (#4569, Joe Hermaszewski).
    * Docx reader:
      + Combine adjacent CodeBlocks with the same attributes into
      a single CodeBlock.  This prevents a multiline codeblock in
      Word from being read as different paragraphs.
    * RST reader:
      + Allow < 3 spaces indent under directives (#4579).
      + Fix anonymous redirects with backticks (#4598).
    * Muse reader (Alexander Krotov):
      + Add support for Text::Amuse multiline headings.
      + Add `<math>` tag support.
      + Add support for `<biblio>` and `<play>` tags.
      + Allow links to have empty descriptions.
      + Require block `<literal>` tags to be on separate lines.
      + Allow `-` in anchors.
      + Allow verse to be indented.
      + Allow nested footnotes.
      + Internal improvements.
    * Muse writer (Alexander Krotov):
      + Escape `>` only at the beginning of a line.
      + Escape `]` in image title.
      + Escape `]` brackets in URLs as `%5D`.
      + Only escape brackets when necessary.
      + Escape ordered list markers.
      + Do not escape list markers unless preceded by space.
      + Escape strings starting with space.
      + Escape semicolons and markers after line break.
      + Escape `;` to avoid accidental comments.
      + Don't break headers, line blocks and tables with line breaks.
      + Correctly output empty headings.
      + Escape horizontal rule only if at the beginning of the line.
      + Escape definition list terms starting with list markers.
      + Place header IDs before header.
      + Improve span writing.
      + Do not join Spans in normalization.
      + Don't align ordered list items.
      + Remove key-value pairs from attributes before normalization.
      + Enable `--wrap=preserve` for all tests by default.
      + Reduced `<verbatim>` tags in output.
      + Internal changes.
    * RST writer:
      + Use more consistent indentation (#4563).  Previously we
      used an odd mix of 3- and 4-space indentation.  Now we use 3-space
      indentation, except for ordered lists, where indentation must
      depend on the width of the list marker.
      + Flatten nested inlines (#4368, Francesco Occhipinti).
      Nested inlines are not valid RST syntax, so we flatten them following
      some readability criteria discussed in #4368.
    * EPUB writer:
      + Ensure that `pagetitle` is always set, even when structured titles
      are used.  This prevents spurious warnings about empty title
      elements (#4486).
    * FB2 writer (Alexander Krotov):
      + Output links inline instead of producing notes.  Previously all links
      were turned into footnotes with unclickable URLs inside.
      + Allow emphasis and notes in titles.
      + Don't intersperse paragraph with empty lines.
      + Convert metadata value `abstract` to book annotation.
      + Use `<empty-line />` for `HorizontalRule` rather than `LineBreak`.
      FB2 does not have a way to represent line breaks inside paragraphs;
      previously we used `<empty-line />` elements, but these are not allowed
      inside paragraphs.
    * Powerpoint writer (Jesse Rosenthal):
      + Handle Quoted Inlines (#4532).
      + Simplify code with `ParseXml`.
      + Allow fallback options when looking for placeholder type.
      + Check reference-doc for all layouts.
      + Simplify speaker notes logic.
      + Change notes state to a simpler per-slide value.
      + Remove `Maybe` from `SpeakerNotes` in `Slide`. `mempty`
      means no speaker notes.
      + Add tests for improved speaker notes.
      + Handle speaker notes earlier in the conversion process.
      + Keep notes with related blocks (#4477).  Some blocks automatically
      split slides (imgs, tables, `column` divs). We assume that any
      speaker notes immediately following these are connected to these
      elements, and keep them with the related blocks, splitting after them.
      + Remove `docProps/thumbnail.jpeg` in data dir (Jesse Rosenthal, #4588).
      It contained a nonfree ICC color calibration profile and is not needed
      for production of a powerpoint document.
    * Markdown writer:
      + Include a blank line at the end of the row in a single-row multiline
      table, to prevent it from being interpreted as a simple table (#4578).
    * CommonMark writer:
      + Correctly ignore LaTeX raw blocks when `raw_tex` is not
      enabled (#4527, quasicomputational).
    * EPUB writer:
      + Add `epub:type="footnotes"` to notes section in EPUB3 (#4489).
    * LaTeX writer:
      + In beamer, don't use format specifier for default ordered lists
      (#4556).  This gives better results for styles that put ordered list
      markers in boxes or circles.
      + Update `\lstinline` delimiters (#4369, Tim Parenti).
    * Ms writer:
      + Use `\f[R]` rather than `\f[]` to reset font (#4552).
      + Use `\f[BI]` and `\f[CB]` in headers, instead of `\f[I]` and `\f[C]`,
      since the header font is automatically bold (#4552).
      + Use `\f[CB]` rather than `\f[BC]` for monospace bold (#4552).
      + Create pdf anchor for a Div with an identifier (#4515).
      + Escape `/` character in anchor ids (#4515).
      + Improve escaping for anchor ids: we now use _uNNN_ instead of uNNN
      to avoid ambiguity.
    * Man writer:
      + Don't escape U+2019 as `'` (#4550).
    * Text.Pandoc.Options:
      + Removed `JsMath`, `LaTeXMathML`, and `GladTeX` constructors from
      `Text.Pandoc.Options.HTMLMathMethod` [API change].
    * Text.Pandoc.Class:
      + `writeMedia`: unescape URI-escaping in file path.  This avoids
      writing things like `file%20one.png` to the file system.
    * Text.Pandoc.Parsing:
      + Fix `romanNumeral` parser (#4480).  We previously accepted 'DDC'
      as 1100.
      + `uri`: don't treat `*` characters at end as part of URI (#4561).
    * Text.Pandoc.MIME:
      + Use the alias `application/eps` for EPS (#2067).
      This will ensure that we retain the eps extension after reading the
      image into a mediabag and writing it again.
    * Text.Pandoc.PDF:
      + Use `withTempDir` in `html2pdf`.
      + With `xelatex`, don't compress images til the last run (#4484).
      This saves time for image-heavy documents.
      + Don't try to convert EPS files (#2067).  `pdflatex` converts them
      itself, and JuicyPixels can't do it.
      + For `pdflatex`, use a temp directory in the working directory.
      Otherwise we can have problems with the EPS conversion pdflatex
      tries to do, which can't operate on a file above the working
      directory without `--shell-escape`.
    * Changes to tests to accommodate changes in pandoc-types.
      In <https://github.com/jgm/pandoc-types/pull/36> we changed
      the table builder to pad cells.  This commit changes tests
      (and two readers) to accord with this behavior.
    * Set default extensions for `beamer` same as `latex`.
    * LaTeX template:
      + Add `beameroption` variable (#4359, Étienne Bersac).
      + Use `pgfpages` package; this is needed for notes on second
      screen in beamer (Étienne Bersac).
      + Add `background-image` variable (#4601, John Muccigrosso).
    * reveal.js template: Add `background-image` variable (#4600,
      John Muccigrosso).
    * ms template: Fix date.  Previously `.ND` was used, but this only
      works if you have a title page, which we don't.  Thanks to @teoric.
    * Removed pragmas for unused extensions (#4506, Anabra).
    * Fix bash completion for `--print-default-data-file` (#4549).
      Previously this looked in the filesystem, even if pandoc
      was compiled with `embed_data_files` (and sometimes it looked
      in a nonexistent build directory).  Now the bash completion
      script just includes a hard-coded list of data file names.
    * MANUAL:
      + Clarify template vs metadata variables (#4501, Mauro Bieg).
      + Fix raw content example (#4479, Mauro Bieg).
      + Specify that you use html for raw output in epub.
      + Add examples for raw docx blocks (#4472, Tristan Stenner).
      The documentation states that the target format name should match
      the output format, which isn't the case for `docx`/`openxml` and
      some others.
      + Don't say that `empty_paragraphs` affects markdown output (#4540).
      + Consolidate input/output format documentation (#4577, Mauro Bieg).
    * New README template. Take in/out formats from manual.
    * Fix example in lua-filters docs (#4459, HeirOfNorton).
    * Use the `-threaded` GHC flag when building benchmarks (#4587,
      Francesco Occhipinti).
    * Bump temporary upper bound to 1.4.
    * Use pandoc-citeproc 0.14.3.1.
    * Use texmath-0.10.1.2 (fixes escapes in math in ms, #4597).
    * Removed old lib directory.  This was used for something long ago,
      but plays no role now.
    * Removed unneeded data file `LaTeXMathML.js`.
    * Create 64- and 32-bit versions of Windows binary packages.
    * Docx reader (Jesse Rosenthal):
      + Add tests for nested smart tags.
      + Parse nested smart tags.
      + Make unwrapSDT into a general `unwrap` function that can unwrap both
      nested SDT tags and smartTags. This makes the SmartTags constructor in
      the Docx type unnecessary, so we remove it (#4446).
      + Remove unused `docxWarnings` (Alexander Krotov).
    * RST reader: Allow unicode bullet characters (#4454).
    * Haddock reader:  Better table handling, using haddock-library's
      new table support, if compiled against a version that
      includes it.  Note that tables with col/rowspans will not
      translate well into Pandoc.
    * Muse reader (Alexander Krotov):
      + Require closing tag to have the same indentation as opening.
      + Do not reparse blocks inside unclosed block tag (#4425).
      + Parse `<class>` tag (supported by Emacs Muse).
      + Do not produce empty Str element for unindented verse lines.
      + Don't allow footnote references inside links.
      + Allow URL to be empty.
      + Require that comment semicolons are in the first column (#4551).
      + Various internal improvements.
    * LaTeX reader:
      + Add support to parse unit string of `\SI` command (closes #4296,
      Marc Schreiber).
    * Haddock writer:  In the writer, we now render tables always as
      grid tables, since Haddock supports these.
    * DokuWiki writer: rewrite backSlashLineBreaks (#4445, Mauro Bieg).
    * Docx writer: Fixed formatting of `DefaultStyle` ordered lists in
      docx writer.  We want decimal for the top level, not lower roman.
    * RST writer:
      + Strip whitespace at beginning and ending of inline containers
      (#4327, Francesco Occhipinti).
      + Filter out empty inline containers (#4434).  There is nothing in
      RST that corresponds to e.g. `Emph []`, so we just ignore elements
      like this (Francesco Occhipinti).
    * Muse writer (Alexander Krotov):
      + Support spans with anchors.
      + Replace smallcaps with emphasis before normalization.
      + Output smallcaps as emphasis.
      + Expand Cite before list normalization.
      + Write empty inline lists as `<verbatim></verbatim>`.
      + Remove empty Str from the beginning of inline lists during normalization.
      + Escape "-" to avoid creating bullet lists.
      + Fix math expansion for more than one expression per paragraph.
      + Expand math before inline list normalization.
    * Dokuwiki writer: fix LineBreaks in Tables (#4313, Mauro Bieg).
    * Ms writer:
      + Asciify pdf anchors, since unicode anchors don't work (#4436).
      Internal links should be converted automatically, so this shouldn't
      affect users directly.
      + Don't escape hyphens as `\-`; that's for a minus sign (#4467).
    * Beamer writer: put hyperlink after `\begin{frame}` and not in the title
      (#4307).  If it's in the title, then we get a titlebar on slides with
      the `plain` attribute, when the id is non-null.  This fixes a regression
      in 2.0.
    * EPUB writer: Remove notes from TOC in nav.xhtml (#4453, Mauro Bieg).
    * JATS writer: Remove extraneous, significant whitespace (#4335,
      Nokome Bentley).
    * html2pdf: inject base tag wih current working directory (#4413, Mauro
      Bieg).  This helps ensure that linked resources are included.
    * Add Semigroup instances for everything for which we defined a
      Monoid instance previously (API change):
      + Text.Pandoc.Class.FileTree.
      + Text.Pandoc.Translations.Translations.
      + Text.Pandoc.Extensions.Extensions.
      + Text.Pandoc.Readers.Odt.StyleReader.Styles.
      + Text.Pandoc.Pretty.Doc.
      + Text.Pandoc.MediaBag.MediaBag.
    * Add custom Prelude to give clean code for Monoid and Semigroup
      that works with ghc 7.10-8.4.  The custom Prelude (`prelude/Prelude`)
      is used for ghc versions < 8.4.  `NoImplicitPrelude` is used
      in all source files, and Prelude is explicitly imported
      (this is necessary for ghci to work properly with the custom prelude).
    * Text.Pandoc.Writers.Shared (Francesco Occhipinti):
      + Export `stripLeadingTrailingSpace`.
      + Don't wrap lines in grid tables when `--wrap=none` (#4320).
      + `gridTable`: Don't wrap lines in tables when `--wrap=none`.  Instead,
      expand cells, even if it results in cells that don't respect relative
      widths or surpass page column width.  This change affects RST,
      Markdown, and Haddock writers.
    * Raise error if someone tries to print docx, odt, etc. template (#4441).
    * LaTeX template: Provide `bidi` package's option using
      `\PassOptionsToPackage`  (#4357, Václav Haisman).  This avoid a
      clash when   `polyglossia` loads it first and then it is loaded again
      for XeLaTeX.
    * ConTeXt template: Added `pdfa` variable to generate PDF/A (#4294, Henri
      Menke).  Instructions on how to install the ICC profiles on ConTeXt
      standalone can be found in the wiki:
      <http://wiki.contextgarden.net/PDFX#ICC_profiles>.
      If the ICC profiles are not available the log will contain error
      messages.
    * Use latest pandoc-types, skylighting
    * Use latest pandoc-citeproc in binary package.
    * Bump upper bound for time, criterion, haddock-library, exceptions,
      http-types, aeson, haddock-library.
    * Bump upper bound tasty-quickcheck 0.10 (#4429, Felix Yan).
    * pandoc.cabal:  fix up other-extensions and language fields.
      Language is now consistently `Haskell2010`, and other-extensions
      is consistently `NoImplicitPrelude`. Everything else to be specified
      in the module header as needed.
    * Removed `old-locale` flag and Text.Pandoc.Compat.Time.
      This is no longer necessary since we no longer support ghc 7.8.
    * Make `weigh-pandoc` into a benchmark program.
      Remove `weigh-pandoc` flag.  `weigh-pandoc` is now built (and run)
      automatically when you build (and run) benchmarks.
    * MANUAL: add instructions for background images reveal.js (#4325, John
      Muccigrosso).
    * appveyor: use VS 2013 environment instead of VS 2015 for Windows builds.
    * Markdown reader:
      + Fix parsing bug with nested fenced divs (#4281).  Previously we allowed
      "nonindent spaces" before the opening and closing `:::`, but this
      interfered with list parsing, so now we require the fences to be flush with
      the margin of the containing block.
    * Commonmark reader:
      + `raw_html` is now on by default.  It can be disabled explicitly
      using `-f commonmark-raw_html`.
    * Org reader (Albert Krewinkel):
      + Move citation tests to separate module.
      + Allow changing emphasis syntax (#4378).  The characters allowed before
      and after emphasis can be configured via `#+pandoc-emphasis-pre` and
      `#+pandoc-emphasis-post`, respectively. This allows to change which
      strings are recognized as emphasized text on a per-document or even
      per-paragraph basis.  Example:
      [#]+pandoc-emphasis-pre: "-\t ('\"{"
      [#]+pandoc-emphasis-post: "-\t\n .,:!?;'\")}["
    * LaTeX reader:
      + Fixed comments inside citations (#4374).
      + Fix regression in package options including underscore (#4424).
      + Make `--trace` work.
      + Fixed parsing of `tabular*` environment (#4279).
    * RST reader:
      + Fix regression in parsing of headers with trailing space (#4280).
    * Muse reader (Alexander Krotov):
      + Enable `<literal>` tags even if amuse extension is enabled.
      Amusewiki disables <literal> tags for security reasons.
      If user wants similar behavior in pandoc, RawBlocks and RawInlines
      can be removed or replaced with filters.
      + Remove space prefix from `<literal>` tag contents.
      + Do not consume whitespace while looking for closing end tag.
      + Convert alphabetical list markers to decimal in round-trip test.
      Alphabetical lists are an addition of Text::Amuse.
      They are not present in Emacs Muse and can be ambiguous
      when list starts with "i.", "c." etc.
      + Allow `<quote>` and other tags to be indented.
      + Allow single colon in definition list term.
      + Fix parsing of verse in lists.
      + Improved parsing efficiency.  Avoid `parseFromString`.
      Lists are parsed in linear instead of exponential time now.
      + Replace ParserState with MuseState.
      + Prioritize lists with roman numerals over alphabetical lists.
      This is to make sure "i." starts a roman numbered list,
      instead of a list with letter "i" (followed by "j", "k", ...").
      + Fix directive parsing.
      + Parse definition lists with multiple descriptions.
      + Parse next list item before parsing more item contents.
      + Fixed a bug: headers did not terminate lists.
      + Move indentation parsing from `definitionListItem` to `definitionList`.
      + Paragraph indentation does not indicate nested quote.
      Muse allows indentation to indicate quotation or alignment,
      but only on the top level, not within a <quote> or list.
      + Require that block tags are on separate lines.
      Text::Amuse already explicitly requires it anyway.
      + Fix matching of closing inline tags.
      + Various internal changes.
      + Fix parsing of nested definition lists.
      + Require only one space for nested definition list indentation.
      + Do not remove trailing whitespace from `<code>`.
      + Fix parsing of trailing whitespace.  Newline after whitespace now
      results in softbreak instead of space.
    * Docx reader (Jesse Rosenthal, except where noted):
      + Handle nested sdt tags (#4415).
      + Don't look up dependant run styles if `+styles` is enabled.
      + Move pandoc inline styling inside custom-style span.
      + Read custom styles (#1843).  This will read all paragraph and
      character classes as divs and spans, respectively. Dependent styles
      will still be resolved, but will be wrapped with appropriate style
      tags. It is controlled by the `+styles` extension (`-f docx+styles`).
      This can be used in conjunction with the `custom-style` feature in the
      docx writer for a pandoc-docx editing workflow. Users can convert from
      an input docx, reading the custom-styles, and then use that same input
      docx file as a reference-doc for producing an output docx file. Styles
      will be maintained across the conversion, even if pandoc doesn't
      understand them.
      + Small change to Fields hyperlink parser.  Previously, unquoted string
      required a space at the end of the line (and consumed it). Now we
      either take a space (and don't consume it), or end of input.
      + Pick table width from the longest row or header (Francesco Occhipinti,
      [#4360]).
    * Muse writer (Alexander Krotov):
      + Change verse markup: `> ` instead of `<verse>` tag.
      + Remove empty strings during inline normalization.
      + Don't indent nested definition lists.
      + Use unicode quotes for quoted text.
      + Write image width specified in percent in Text::Amuse mode.
      + Don't wrap displayMath into `<verse>`.
      + Escape nonbreaking space (`~~`).
      + Join code with different attributes during normalization.
      + Indent lists inside Div.
      + Support definitions with multiple descriptions.
    * Powerpoint writer (Jesse Rosenthal):
      + Use table styles This will use the default table style in the
      reference-doc file. As a result they will be easier when using
      in a template, and match the color scheme.
      + Remove empty slides.  Because of the way that slides were split, these
      could be accidentally produced by comments after images.  When animations
      are added, there will be a way to add an empty slide with either
      incremental lists or pauses.
      + Implement syntax highlighting.  Note that background colors can't
      be implemented in PowerPoint, so highlighting styles that require
      these will be incomplete.
      + New test framework for pptx.  We now compare the output of the
      Powerpoint writer with files that we know to (a) not be corrupt,
      and (b) to show the desired output behavior (details below).
      + Add `notesMaster` to `presentation.xml` if necessary.
      + Ignore links and (end)notes in speaker notes.
      + Output speaker notes.
      + Read speaker note templates conditionally.  If there are speaker
      notes in the presentation, we read in the notesMasters templates
      from the reference pptx file.
      + Fix deletion track changes (#4303, Jesse Rosenthal).
    * Markdown writer: properly escape @ to avoid capture as citation
      (#4366).
    * LaTeX writer:
      + Put hypertarget inside figure environment (#4388).
      This works around a problem with the endfloat package and
      makes pandoc's output compatible with it.
      + Fix image height with percentage (#4389).  This previously caused
      the image to be resized to a percentage of textwidth, rather than
      textheight.
    * ConTeXt writer (Henri Menke):
      + New section syntax and support `--section-divs` (#2609).
      `\section[my-header]{My Header}` ->
      `\section[title={My Header},reference={my-header}]`.
      The ConTeXt writer now supports the `--section-divs` option to
      write sections in the fenced style, with `\startsection` and
      `\stopsection`.
      + xtables: correct wrong usage of caption (Henri Menke).
    * Docx writer:
      + Fix image resizing with multiple images (#3930, Andrew Pritchard).
      + Use new golden framework (Jesse Rosenthal).
      + Make more deterministic to facilitate testing (Jesse Rosenthal).
    - `getUniqueId` now calls to the state to get an incremented digit,
      instead of calling to P.uniqueHash.
    - we always start the PRNG in mkNumbering/mkAbstractNum with the same
      seed (1848), so our randoms should be the same each time.
      + Fix ids in comment writing (Jesse Rosenthal).  Comments from
      `--track-changes=all` were producing corrupt docx, because the
      writer was trying to get id from the `(ID,_,_)` field of
      the attributes, and ignoring the "id" entry in the key-value pairs. We
      now check both.
    * Ms writer: Added papersize variable.
    * TEI writer:
      + Use `height` instead of `depth` for images (#4331).
      + Ensure that id prefix is always used.
      + Don't emit `role` attribute; that was a leftover from the
      Docbook writer.
      + Use 'xml:id', not 'id' attribute (#4371).
    * AsciiDoc writer:
      + Do not output implicit heading IDs (#4363, Alexander
      Krotov).  Convert to `asciidoc-auto_identifiers` for old behaviour.
    * RST writer:
      + Remove `blockToRST'` moving its logic into `fixBlocks`
      (Francesco Occhipinti).
      + Insert comment between lists and quotes (#4248, Francesco Occchipinti).
    * RST template: remove definition of 'math' role as raw.
      This used to be needed prior to v 0.8 of docutils, but
      now math support is built-in.
    * Slides: Use divs to set incremental/non-incremental (#4381,
      Jesse Rosenthal).  The old method (list inside blockquote) still
      works, but we are encouraging the use of divs with class
      `incremental` or `nonincremental`.
    * Text.Pandoc.ImageSize:
      + Make image size detection for PDFs more robust (#4322).
      + Determine image size for PDFs (#4322).
      + EMF Image size support (#4375, Andrew Pritchard).
    * Text.Pandoc.Extensions:
      + Add `Ext_styles` (Jesse Rosenthal, API change).  This will be used in
      the docx reader (defaulting to off) to read pargraph and character
      styles not understood by pandoc (as divs and spans, respectively).
      + Made `Ext_raw_html` default for `commonmark` format.
    * Text.Pandoc.Parsing:
      + Export `manyUntil` (Alexander Krotov, API change).
      + Export improved `sepBy1` (Alexander Krotov).
      + Export list marker parsers: `upperRoman`, `lowerRoman`,
      `decimal`, `lowerAlpha`, `upperAlpha` (Alexander Krotov, API change).
    * Tests/Lua: fix tests on windows (Albert Krewinkel).
    * Lua: register script name in global variable (#4393).  The name of the Lua
      script which is executed is made available in the global Lua variable
      `PANDOC_SCRIPT_FILE`, both for Lua filters and custom writers.
    * Tests: Abstract powerpoint tests out to OOXML tests (Jesse Rosenthal).
      There is very little pptx-specific in these tests, so we abstract out
      the basic testing function so it can be used for docx as well. This
      should allow us to catch some errors in the docx writer that slipped
      by the roundtrip testing.
    * Lua filters: store constructors in registry (Albert Krewinkel).  Lua
      functions used to construct AST element values are stored in the Lua
      registry for quicker access. Getting a value from the registry is much
      faster than getting a global value (partly to idiosyncrasies of hslua);
      this change results in a considerable performance boost.
    * Documentation:
      + `doc/org.md` Add draft of Org-mode documentation (Albert Krewinkel).
      + `doc/lua-filters.md`: document global vars set for filters
      (Albert Krewinkel).
      + INSTALL.md: mention Stack version. (#4343, Adam Brandizzi).
      + MANUAL: add documentation on custom styles (Jesse Rosenthal).
      + MANUAL.txt: Document incremental and nonincremental divs (Jesse
      Rosenthal).  Blockquoted lists are still described, but fenced divs are
      presented in preference.
      + MANUAL.txt: document header and footer variables (newmana).
      + MANUAL.txt: self-contained implies standalone (#4304, Daniel Lublin).
      + CONTRIBUTING.md: label was renamed. (#4310, Alexander Brandizzi).
    * Require tagsoup 0.14.3 (#4282), fixing HTML tokenization bug.
    * Use latest texmath.
    * Use latest pandoc-citeproc.
    * Allow exceptions 0.9.
    * Require aeson-pretty 0.8.5 (#4394).
    * Bump blaze-markup, blaze-html lower bounds to 0.8, 0.9 (#4334).
    * Update tagsoup to 0.14.6 (Alexander Krotov, #4282).
    * Removed ghc-prof-options.  As of cabal 1.24, sensible defaults are used.
    * Update default.nix to current nixpkgs-unstable for hslua-0.9.5 (#4348,
      jarlg).
    * Markdown reader:
      + Don't coalesce adjacent raw LaTeX blocks if they are separated by a
      blank line.  See lierdakil/pandoc-crossref#160.
      + Improved `inlinesInBalancedBrackets` (#4272, jgm/pandoc-citeproc#315).
      The change both improves performance and fixes a regression whereby
      normal citations inside inline notes and figure captions were not
      parsed correctly.
    * RST reader:
      + Better handling for headers with an anchor (#4240).  Instead of creating a
      Div containing the header, we put the id directly on the header.
      This way header promotion will work properly.
      + Add aligned environment when needed in math (#4254).  `rst2latex.py`
      uses an `align*` environment for math in `.. math::` blocks, so this
      math may contain line breaks.  If it does, we put the math in an
      `aligned` environment to simulate `rst2latex.py`'s behavior.
    * HTML reader:
      + Fix col width parsing for percentages < 10% (#4262, n3fariox).
    * LaTeX reader:
      + Advance source position at end of stream.
      + Pass through macro defs in `rawLaTeXBlock` even if the `latex_macros`
      extension is set (#4246).  This reverts to earlier behavior and is
      probably safer on the whole, since some macros only modify things in
      included packages, which pandoc's macro expansion can't modify.
      + Fixed pos calculation in tokenizing escaped space.
      + Allow macro definitions inside macros (#4253).  Previously we went into
      an infinite loop with
      ```
      \newcommand{\noop}[1]{#1}
      \noop{\newcommand{\foo}[1]{#1}}
      \foo{hi}
      ```
      + Fix inconsistent column widths (#4238).  This fixes a bug whereby column
      widths for the body were different from widths for the header in some
      tables.
    * Docx reader (Jesse Rosenthal):
      + Parse hyperlinks in `instrText` tags (#3389, #4266).  This was a form of
      hyperlink found in older versions of word. The changes introduced for
      this, though, create a framework for parsing further fields in MS Word
      (see the spec, ECMA-376-1:2016, §17.16.5, for more on these fields).
      We introduce a new module, `Text.Pandoc.Readers.Docx.Fields` which
      contains a simple parsec parser. At the moment, only simple hyperlink
      fields are accepted, but that can be extended in the future.
    * Muse reader (Alexander Krotov):
      + Parse `~~` as non-breaking space in Text::Amuse mode.
      + Refactor list parsing.
    * Powerpoint writer (Jesse Rosenthal):
      + Change reference to `notesSlide` to `endNotesSlide`.
      + Move image sizing into `picProps`.
      + Improve table placement.
      + Make our own `_rels/.rels` file.
      + Import reference-doc images properly.
      + Move `Presentation.hs` out of `PandocMonad`.
      + Refactor into separate modules.  T.P.W.Powerpoint.Presentation
      defines the Presentation datatype and goes Pandoc->Presentation;
      T.P.W.Pandoc.Output goes Presentation->Archive.
      Text.Pandoc.Writers.Powerpoint a thin wrapper around the two modules.
      + Avoid overlapping blocks in column output.
      + Position images correctly in two-column layout.
      + Make content shape retrieval environment-aware.
      + Improve image handling.  We now determine image and caption placement
      by getting the dimensions of the content box in a given layout.
      This allows for images to be correctly sized and positioned in a
      different template.  Note that images without captions and headers are
      no longer full-screened. We can't do this dependably in different
      layouts, because we don't know where the header is (it could be to
      the side of the content, for example).
      + Read presentation size from reference file.  Our presentation size is
      now dependent on the reference/template file we use.
      + Handle (sub)headers above slidelevel correctly.  Above the slidelevel,
      subheaders will be printed in bold and given a bit of extra space
      before them. Note that at the moment, no distinction is made between
      levels of headers above the slide header, though that can be changed.
      + Check for required files.  Since we now import from reference/dist
      file by glob, we need to make sure that we're getting the files we
      need to make a non-corrupt Powerpoint. This performs that check.
      + Improve templating using `--reference-doc`.  Templating should work
      much more reliably now.
      + Include Notes slide in TOC.
      + Set notes slide header to slide-level.
      + Add table of contents.  This is triggered by the `--toc` flag. Note
      that in a long slide deck this risks overrunning the text box. The user
      can address this by setting `--toc-depth=1`.
      + Set notes slide number correctly.
      + Clean up adding metadata slide.  We want to count the slide numbers
      correctly if it's in there.
      + Add anchor links.  For anchor-type links (`[foo](#bar)`) we produce
      an anchor link. In powerpoint these are links to slides, so we keep
      track of a map relating anchors to the slides they occur on.
      + Make the slide number available to the blocks.  For anchors,
      block-processing functions need to know what slide number
      they're in. We make the `envCurSlideId` available to blocks.
      + Move `curSlideId` to environment.
      + Allow setting `toc-title` in metadata.
      + Link notes to endnotes slide.
    * Markdown writer:
      + Fix cell width calculation (#4265).  Previously we could get
      ever-lengthening cell widths when a table was run repeatedly through
      `pandoc -f markdown -t markdown`.
    * LaTeX writer:
      + Escape `&` in lstinline (Robert Schütz).
    * ConTeXt writer:
      + Use xtables instead of Tables (#4223, Henri Menke).
      Default to xtables for context output.  Natural Tables are used
      if the new `ntb` extension is set.
    * HTML writer:
      + Fixed footnote backlinks with `--id-prefix` (#4235).
    * `Text.Pandoc.Extensions`:  Added `Ext_ntb` constructor (API change,
      Henri Menke).
    * `Text.Pandoc.ImageSize`: add derived `Eq` instance to `Dimension`
      (Jesse Rosenthal, API change).
    * Lua filters (Albert Krewinkel):
      + Make `PANDOC_READER_OPTIONS` available.
      The options which were used to read the document are made available to
      Lua filters via the `PANDOC_READER_OPTIONS` global.
      + Add lua module `pandoc.utils.run_json_filter`, which runs a JSON filter
      on a Pandoc document.
      + Refactor filter-handling code into `Text.Pandoc.Filter.JSON`,
      `Text.Pandoc.Filter.Lua`, and `Text.Pandoc.Filter.Path`.
      + Improve error messages.  Provide more context about the task
      which caused an error.
    * data/pandoc.lua (Albert Krewinkel):
      + Accept singleton inline as a list.  Every constructor which accepts a
      list of inlines now also accepts a single inline element for
      convenience.
      + Accept single block as singleton list. Every constructor which accepts
      a list of blocks now also accepts a single block element for
      convenience.  Furthermore, strings are accepted as shorthand for
      `{pandoc.Str "text"}` in constructors.
      + Add attr, listAttributes accessors.  Elements with
      attributes got an additional `attr` accessor. Attributes were
      accessible only via the `identifier`, `classes`, and `attributes`,
      which was in conflict with the documentation, which indirectly states
      that such elements have the an `attr` property.
      + Drop `_VERSION`.  Having a `_VERSION` became superfluous, as this
      module is closely tied to the pandoc version, which is available via
      `PANDOC_VERSION`.
      + Fix access to Attr components.  Accessing an Attr value (e.g.,
      ` Attr().classes`) was broken; the more common case of accessing it via
      an Inline or Block element was unaffected by this.
    * Move `metaValueToInlines` to from Docx writer to
      `Text.Pandoc.Writers.Shared`, so it can be used by other writers
      (Jesse Rosenthal).
    * MANUAL.txt:
      + Clarify otherlangs in LaTeX (#4072).
      + Clarify `latex_macros` extension.
      + Recommend use of `raw_attribute` extension in header includes (#4253).
    * Allow latest QuickCheck, tasty, criterion.
    * Remove custom prelude and ghc 7.8 support.
    * Reduce compiler noise (exact paths for compiled modules).
    * Allow filters and lua filters to be interspersed (#4196).  Previously
      we ran all lua filters before JSON filters.  Now we run filters in
      the order they are presented on the command line, whether lua or JSON.
      There are two incompatible API changes: The type of `applyFilters`
      has changed, and `applyLuaFilters` has been removed.  `Filter` is
      also now exported.
    * Use latest skylighting and omit the `missingIncludes` check, fixing
      a major performance regression in earlier releases of the 2.x series
      (#4226).  Behavior change: If you use a custom syntax definition that
      refers to a syntax you haven't loaded, pandoc will now complain when
      it is highlighting the text, rather than doing a check at the start.
      This change dramatically speeds up invocations of pandoc on short
      inputs.
    * Text.Pandoc.Class: make `FileTree` opaque (don't export
      `FileTree` constructor).  This forces users to interact with it using
      `insertInFileTree` and `getFileInfo`, which normalize file names.
    * Markdown reader:
      + Rewrite `inlinesInBalancedBrackets`.  The rewrite is much more
      direct, avoiding `parseFromString`.  And it performs significantly
      better; unfortunately, parsing time still increases exponentially
      (see #1735).
      + Avoid parsing raw tex unless `\` + letter seen.  This seems to
      help with the performance problem, #4216.
    * LaTeX reader: Simplified a check for raw tex command.
    * Muse reader (Alexander Krotov):
      + Enable round trip test (#4107).
      + Automatically translate `#cover` into `#cover-image`.
      Amusewiki uses #cover directive to specify cover image.
    * Docx reader (Jesse Rosenthal):
      + Allow for insertion/deletion of paragraphs (#3927).
      If the paragraph has a deleted or inserted paragraph break (depending
      on the track-changes setting) we hold onto it until the next
      paragraph. This takes care of accept and reject. For this we introduce
      a new state which holds the ils from the previous para if necessary.
      For `--track-changes=all`, we add an empty span with class
      `paragraph-insertion`/`paragraph-deletion` at the end of the paragraph
      prior to the break to be inserted or deleted.
      + Remove unused anchors (#3679).  Docx produces a lot of anchors with
      nothing pointing to them---we now remove these to produce cleaner
      output. Note that this has to occur at the end of the process
      because it has to follow link/anchor rewriting.
      + Read multiple children of `w:sdtContents`.
      + Combine adjacent anchors.  There isn't any reason to have numerous
      anchors in the same place, since we can't maintain docx's
      non-nesting overlapping. So we reduce to a single anchor.
      + Improved tests.
    * Muse writer (Alexander Krotov): don't escape URIs from AST
    * Docx writer:
      + Removed redundant subtitle in title (Sebastian Talmon).
      + `firstRow` table definition compatibility for Word 2016 (Sebastian
      Talmon).  Word 2016 seems to use a default value of "1" for table
      headers, if there is no firstRow definition (although a default
      value of 0 is documented), so all tables get the first Row formatted
      as header.  Setting the parameter to 0 if the table has no header
      row fixes this for Word 2016
      + Fix custom styles with spaces in the name (#3290).
    * Powerpoint writer (Jesse Rosenthal):
      + Ignore Notes div for parity with other slide outputs.
      + Set default slidelevel correctly.  We had previously defaulted to
      slideLevel 2. Now we use the correct behavior of defaulting to the
      highest level header followed by content. We change an expected test
      result to match this behavior.
      + Split blocks correctly for linked images.
      + Combine adjacent runs.
      + Make inline code inherit code size.  Previously (a) the code size
      wasn't set when we force size, and (b) the properties was set from
      the default, instead of inheriting.
      + Simplify `replaceNamedChildren` function.
      + Allow linked images.  The following markdown:
      `[![Image Title](image.jpg)](http://www.example.com)`
      will now produce a linked image in the resulting PowerPoint file.
      + Fix error with empty table cell.  We require an empty `<a:p>` tag,
      even if the cell contains no paragraphs---otherwise PowerPoint
      complains of corruption.
      + Implement two-column slides.  This uses the columns/column div
      format described in the pandoc manual. At the moment, only two
      columns (half the screen each) are allowed. Custom widths are not
      supported.
      + Added more tests.
    * OpenDocument/ODT writers: improved rendering of formulas (#4170, oltolm).
    * Lua filters (Albert Krewinkel):
      + `data/pandoc.lua`: drop 'pandoc-api-version' from Pandoc objects
      + The current pandoc-types version is made available to Lua programs in
      the global `PANDOC_API_VERSION`. It contains the version as a list of
      numbers.
      + The pandoc version available as a global `PANDOC_VERSION` (a list
      of numbers).
      + `data/pandoc.lua`: make `Attr` an `AstElement`.
      + `data/pandoc.lua`: make all types subtypes of `AstElement`.
      `Pandoc`, `Meta`, and `Citation` were just plain functions and did
      not set a metatable on the returned value, which made it difficult
      to amend objects of these types with new behavior. They are now
      subtypes of AstElement, meaning that all their objects can gain
      new features when a method is added to the behavior object
      (e.g., `pandoc.Pandoc.behavior`).
      + `data/pandoc.lua`: split type and behavior tables.  Clearly distinguish
      between a type and the behavioral properties of an instance of that
      type. The behavior of a type (and all its subtypes) can now be
      amended by adding methods to that types `behavior` object, without
      exposing the type objects internals.  E.g.:
      ```lua
      pandoc.Inline.behavior.frob = function () print'42' end
      local str = pandoc.Str'hello'
      str.frob() -- outputs '42'
      ```
      + `data/pandoc.lua`: fix Element inheritance.  Extending all elements
      of a given type (e.g., all inline elements) was difficult, as the
      table used to lookup unknown methods would be reset every time a
      new element of that type was created, preventing recursive property
      lookup. This is was changed in that all methods and attributes of
      supertypes are now available to their subtypes.
      + `data/pandoc.lua`: fix attribute names of Citation (#4222).  The
      fields were named like the Haskell fields, not like the documented,
      shorter version.  The names are changed to match the documentation
      and Citations are given a shared metatable to enable simple
      extensibility.
      + `data/pandoc.lua`: drop function `pandoc.global_filter`.
      + Bump `hslua` version to 0.9.5.  This version fixes a bug that made it
      difficult to handle failures while getting lists or a Map from Lua.
      A bug in pandoc, which made it necessary to always pass a tag when
      using MetaList or MetaBlock, is fixed as a result. Using the pandoc
      module's constructor functions for these values is now optional
      (if still recommended).
      + Stop exporting `pushPandocModule` (API change).  The introduction
      of `runPandocLua` renders direct use of this function obsolete.
      + Update generation of module docs for lua filters.
      + `Lua.Module.Utils`: make stringify work on `MetaValues` (John
      MacFarlane).  I'm sure this was intended in the first place,
      but currently only `Meta` is supported.
    * Improve benchmarks.
      + Set the default extensions properly.
      + Improve benchmark argument parsing.  You can now say
      `make bench BENCHARGS="markdown latex reader"` and both the
      markdown and latex readers will be benchmarked.
    * MANUAL.txt simplify and add more structure (Mauro Bieg).
    * Generate README.md from template and MANUAL.txt.
      `make README.md` will generate the README.md after changes
      to MANUAL.txt have been made.
    * Update copyright notices to include 2018 (Albert Krewinkel).
    * Added `jats` as an input format.
      + Add Text.Pandoc.Readers.JATS, exporting `readJATS` (API
      change) (Hamish Mackenzie).
      + Improved citation handling in JATS reader.  JATS citations
      are now converted to pandoc citations, and JATS ref-lists
      are converted into a `references` field in metadata, suitable
      for use with pandoc-citeproc. Thus a JATS article with embedded
      bibliographic information can be processed with pandoc and
      pandoc-citeproc to produce a formatted bibliography.
    * Allow `--list-extensions` to take an optional FORMAT argument.
      This lists the extensions set by default for the selected FORMAT.
      The extensions are now alphabetized, and the `+` or `-`
      indicating the default setting comes before, rather than after,
      the extension.
    * Markdown reader:
      + Preserve original whitespace between blocks.
      + Recognize `\placeformula` as context.
      + Be pickier about table captions.  A caption starts with a `:` which
      can't be followed by punctuation.  Otherwise we can falsely interpret
      the start of a fenced div, or even a table header line like
      `:--:|:--:`, as a caption.
      + Always use four space rule for example lists.  It would be awkward
      to indent example list contents to the first non-space character after
      the label, since example list labels are often long.  Thanks to
      Bernhard Fisseni for the suggestion.
      + Improve raw tex parsing.  Note that the Markdown reader is also
      affected by the `latex_macros` extension changes described below
      under the LaTeX reader.
    * LaTeX reader:
      + `latex_macros` extension changes (#4179).  Don't pass through macro
      definitions themselves when `latex_macros` is set.  The macros
      have already been applied.  If `latex_macros` is enabled, then
      `rawLaTeXBlock` in Text.Pandoc.Readers.LaTeX will succeed in parsing
      a macro definition, and will update pandoc's internal macro map
      accordingly, but the empty string will be returned.
      + Export `tokenize`, `untokenize` (API change).
      + Use `applyMacros` in `rawLaTeXBlock`, `rawLaTeXInline`.
      + Refactored `inlineCommand`.
      + Fix bug in tokenizer.  Material following `^^` was
      dropped if it wasn't a character escape.  This only affected
      invalid LaTeX, so we didn't see it in the wild, but it appeared
      in a QuickCheck test failure.
      + Fix regression in LateX tokenization (#4159).  This mainly affects the
      Markdown reader when parsing raw LaTeX with escaped spaces.
      + Add tests of LaTeX tokenizer.
      + Support `\foreignlanguage` from babel.
      + Be more tolerant of `&` character (#4208).  This allows us to parse
      unknown tabular environments as raw LaTeX.
    * Muse reader (Alexander Krotov):
      + Parse anchors immediately after headings as IDs.
      + Require that note references does not start with 0.
      + Parse empty comments correctly.
    * Org reader (Albert Krewinkel):
      + Fix asterisks-related parsing error (#4180).
      + Support minlevel option for includes (#4154).  The level of headers
      in included files can be shifted to a higher level by specifying a
      minimum header level via the `:minlevel` parameter. E.g.
      `#+include: "tour.org" :minlevel 1` will shift the headers in
      tour.org such that the topmost headers become level 1 headers.
      + Break-up org reader test file into multiple modules.
    * OPML reader:
      + Enable raw HTML and other extensions by default for notes
      (#4164).  This fixes a regression in 2.0.  Note that extensions can
      now be individually disabled, e.g.  `-f opml-smart-raw_html`.
    * RST reader:
      + Allow empty list items (#4193).
      + More accurate parsing of references (#4156).  Previously we erroneously
      included the enclosing backticks in a reference ID (#4156).  This
      change also disables interpretation of syntax inside references, as
      in docutils.  So, there is no emphasis in `` `my *link*`_ ``.
    * Docx reader:
      + Continue lists after interruption (#4025, Jesse Rosenthal).
      Docx expects that lists will continue where they left off after an
      interruption and introduces a new id if a list is starting again. So
      we keep track of the state of lists and use them to define a "start"
      attribute, if necessary.
      + Add tests for structured document tags unwrapping (Jesse Rosenthal).
      + Preprocess Document body to unwrap `w:sdt` elements (Jesse Rosenthal,
      [#4190]).
    * Plain writer:
      + Don't linkify table of contents.
    * RST writer:
      + Fix anchors for headers (#4188).  We were missing an `_`.
    * PowerPoint writer (Jesse Rosenthal):
      + Treat lists inside BlockQuotes as lists.  We don't yet produce
      incremental lists in PowerPoint, but we should at least treat lists
      inside BlockQuotes as lists, for compatibility with other slide formats.
      + Add ability to force size.  This replaces the more specific
      `blockQuote runProp`, which only affected the size of blockquotes. We
      can use this for notes, etc.
      + Implement notes.  This currently prints all notes on a final slide.
      Note that at the moment, there is a danger of text overflowing the
      note slide, since there is no logic for adding further slides.
      + Implement basic definition list functionality to PowerPoint writer.
      + Don't look for default template file for Powerpoint (#4181).
      + Add pptx to isTextFormat list.  This is used to check standalone
      and not writing to the terminal.
      + Obey slide level option (Jesse Rosenthal).
      + Introduce tests.
    * Docx writer:
      + Ensure that `distArchive` is the one that comes with pandoc
      (#4182).  Previously a `reference.docx` in `~/.pandoc` (or the user data
      dir) would be used instead, and this could cause problems because a
      user-modified docx sometimes lacks vital sections that we count
      on the `distArchive` to supply.
    * Org writer:
      + Do not wrap "-" to avoid accidental bullet lists (Alexander Krotov).
      + Don't allow fn refs to wrap to beginning of line (#4171, with help from
      Alexander Krotov).  Otherwise they can be interpreted as footnote
      definitions.
    * Muse writer (Alexander Krotov):
      + Don't wrap note references to the next line (#4172).
    * HTML writer:
      + Use br elements in line blocks instead of relying on CSS
      (#4162).  HTML-based templates have had the custom CSS for
      `div.line-block` removed.  Those maintaining custom templates will want
      to remove this too.  We still enclose line blocks in a div with class
      `line-block`.
    * LaTeX writer:
      + Use `\renewcommand` for `\textlatin` with babel (#4161).
      This avoids a clash with a deprecated `\textlatin` command defined
      in Babel.
      + Allow fragile=singleslide attribute in beamer slides (#4169).
      + Use `\endhead` after `\toprule` in headerless tables (#4207).
    * FB2 writer:
      + Add cover image specified by `cover-image` meta (Alexander Krotov,
      [#4195]).
    * JATS writer (Hamish Mackenzie):
      + Support writing `<fig>` and `<table-wrap>` elements
      with `<title>` and `<caption>` inside them by using Divs with class set
      to one of `fig`, `table-wrap` or `caption` (Hamish Mackenzie).  The
      title is included as a Heading so the constraint on where Heading can
      occur is also relaxed.
      + Leave out empty alt attributes on links.
      + Deduplicate image mime type code.
      + Make `<p>` optional in `<td>` and `<th>` (#4178).
      + Self closing tags for empty xref (#4187).
      + Improve support for code language.
    * Custom writer:
      + Use init file to setup Lua interpreter (Albert Krewinkel).
      The same init file (`data/init`) that is used to setup the Lua
      interpreter for Lua filters is also used to setup the interpreter of
      custom writers.lua.
      + Define instances for newtype wrapper (Albert Krewinkel).  The custom
      writer used its own `ToLuaStack` instance definitions, which made
      it difficult to share code with Lua filters, as this could result
      in conflicting instances.  A `Stringify` wrapper is introduced to
      avoid this problem.
      + Added tests for custom writer.
      + Fixed definition lists and tables in `data/sample.lua`.
    * Fixed regression: when target is PDF, writer extensions were being
      ignored.  So, for example, `pandoc -t latex-smart -o file.pdf`
      did not work properly.
    * Lua modules (Albert Krewinkel):
      + Add `pandoc.utils` module, to hold utility functions.
      + Create a Haskell module Text.Pandoc.Lua.Module.Pandoc to
      define the `pandoc` lua module.
      + Make a Haskell module for each Lua module. Move definitions for the
      `pandoc.mediabag` modules to a separate Haskell module.
      + Move `sha1` from the main `pandoc` module to `pandoc.utils`.
      + Add function `pandoc.utils.hierarchicalize` (convert list of
      Pandoc blocks into (hierarchical) list of Elements).
      + Add function `pandoc.utils.normalize_date` (parses a date and
      converts it (if possible) to "YYYY-MM-DD" format).
      + Add function `pandoc.utils.to_roman_numeral` (allows conversion
      of numbers below 4000 into roman numerals).
      + Add function `pandoc.utils.stringify` (converts any AST element
      to a string with formatting removed).
      + `data/init.lua`: load `pandoc.utils` by default
      + Turn pipe, read into full Haskell functions.  The `pipe` and `read`
      utility functions are converted from hybrid lua/haskell functions
      into full Haskell functions. This avoids the need for intermediate
      `_pipe`/`_read` helper functions, which have dropped.
      + pandoc.lua: re-add missing MetaMap function.  This was a bug
      introduced in version 2.0.4.
    * Text.Pandoc.Class: Add `insertInFileTree` [API change].  This gives
      a pure way to insert an ersatz file into a `FileTree`.  In addition, we
      normalize paths both on insertion and on lookup.
    * Text.Pandoc.Shared: export `blocksToInlines'` (API change, Maura Bieg).
    * Text.Pandoc.MIME: Add opus to MIME type table as audio/ogg (#4198).
    * Text.Pandoc.Extensions:   Alphabetical order constructors for
      `Extension`.  This makes them appear in order in `--list-extensions`.
    * Allow lenient decoding of latex error logs, which are not always
      properly UTF8-encoded (#4200).
    * Update latex template to work with recent versions of beamer.
      The old template produced numbered sections with some recent
      versions of beamer.  Thanks to Thomas Hodgson.
    * Updated reference.docx (#4175).  Instead of just "Hello, world", the
      document now contains exemplars of most of the styles that have an
      effect on pandoc documents.  This makes it easier to see the effect
      of style changes.
    * Removed `default.theme` data file (#4096).  It is no longer needed now
      that we have `--print-highlight-style`.
    * Added `stack.lts9.yaml` for building with lts 9 and ghc 8.0.2.
      We still need this for the alpine static linux build, since
      we don't have ghc 8.2.2 for that yet.
    * Removed `stack.pkg.yaml`.  We only really need `stack.yaml`; we
      can put flag settings for pandoc-citeproc there.
    * Makefile: Add 'trypandoc' and 'pandoc-templates' targets to
      make releases easier.
    * MANUAL.txt:
      + Add note on what formats have `+smart` by default.
      + Use native syntax for custom-style (#4174, Mauro Bieg).
      + Introduce dedicated Extensions section, since some extensions
      affect formats other than markdown (Mauro Bieg, #4204).
      + Clarify default html output for `--section-divs` (Richard Edwards).
    * filters.md: say that Text.Pandoc.JSON comes form pandoc-types.
      Closes jgm/pandoc-website#16.
    * epub.md: Delete removed `-S` option from command (#4151, Georger Araújo).
    * Fix a bug in 2.0.4, whereby pandoc could not read the theme files
      generated with `--print-highlight-style` (#4133).  Improve JSON
      serialization of styles.
    * Fix CSS issues involving line numbers (#4128).
      Highlighted code blocks are now enclosed in a div with class `sourceCode`.
      Highlighting CSS no longer sets a generic color for pre and code; we only
      set these for class `sourceCode`.
    * `--pdf-engine-opt`: fix bug where option order was reversed (#4137).
    * Add PowerPoint (pptx) writer (Jesse Rosenthal).
      It works following the standard Pandoc conventions for making other
      sorts of slides. Caveats:
      + Syntax highlighting is not yet implemented. (This is difficult
      because there are no character classes in Powerpoint.)
      + Footnotes and Definition lists are not yet implemented. (Notes will
      usually take the form of a final slide.
      + Image placement and auto-resizing has a few glitches.
      + Reference powerpoint files don't work dependably from the command
      line. This will be implemented, but at the moment users are advised
      to change themes from within Powerpoint.
    * Create shared Text.Pandoc.Writers.OOXML module (Jesse Rosenthal).
      This is for functions used by both Powerpoint and Docx writers.
    * Add default pptx data for Powerpoint writer (Jesse Rosenthal).
    * Add `empty_paragraphs` extension.
      + Deprecate `--strip-empty-paragraphs` option.  Instead we now
      use an `empty_paragraphs` extension that can be enabled on
      the reader or writer.  By default, disabled.
      + Add `Ext_empty_paragraphs` constructor to `Extension`.
      + Revert "Docx reader: don't strip out empty paragraphs."
      This reverts commit d6c58eb836f033a48955796de4d9ffb3b30e297b.
      + Implement `empty_paragraphs` extension in docx reader and writer,
      opendocument writer, HTML reader and writer.
      + Add tests for `empty_paragraphs` extension.
    * Markdown reader:
      + Don't parse native div as table caption (#4119).
      + Improved computation of column widths in pipe tables.
      Pipe tables with lines longer than the text width (as set
      by `--columns`) are now scaled to text width, with the relative
      widths of columns determined by the ratios between the
      header lines.  Previously we computed column widths using
      the ratio of header line lengths to column width, so that
      tables with narrow header lines were extremely thin, which
      was very rarely the desired result.
    * LaTeX reader: fix `\` before newline (#4134).  This should be a space,
      as long as it's not followed by a blank line. This has been fixed at the
      tokenizer level.
    * Muse reader (Alexander Krotov):
      + Add test for `#disable-tables` directive in Emacs mode.
      + Don't allow emphasis to be preceded by letter.
      + Add underline support in Emacs Muse mode..
      + Support multiline directives in Amusewiki mode
    * Man writer: omit internal links (#4136).  That is, just print the link
      text without the URL.
    * Markdown reader: accept processing instructions as raw HTML (#4125).
    * Lua filters (Albert Krewinkel):
      + Use script to initialize the interpreter.  The file `init.lua` is
      used to initialize the Lua interpreter which is used in Lua filters.
      This gives users the option to require libraries which they want to
      use in all of their filters, and to extend default modules.
      + Fix package loading for Lua 5.1.  The list of package searchers is
      named `package.loaders` in Lua 5.1 and LuaJIT, and `package.searchers`
      in Lua 5.2 and later.
      + Refactor lua module handling.  The integration with Lua's package/module
      system is improved: A pandoc-specific package searcher is prepended to
      the searchers in `package.searchers`. The modules `pandoc` and
      `pandoc.mediabag` can now be loaded via `require`.
      + Bump lower bound of hslua.  The release hslua 0.9.3 contains a new
      function which makes using Haskell functions as package loaders much
      easier.
    * reveal.js template:  add title-slide identifier to title slide (#4120).
      This allows it to be styled more easily.
    * LaTeX template: Added support for `pagestyle` variable (#4135,
      Thomas Hodgson)
    * Add `-threaded` to ghc-options for executable (#4130, fixes a build
      error on linux).
    * Add `--print-highlight-style` option.  This generates a JSON version
      of a highlighting style, which can be saved as a `.theme` file, modified,
      and used with `--highlight-style` (#4106, #4096).
    * Add `--strip-empty-paragraphs` option.  This works for any input format.
      It is primarily intended for use with docx and odt documents where
      empty paragraphs have been used for inter-paragraph spaces.
    * Support `--webtex` for `gfm` output.
    * Recognize `.muse` file extension.
    * Support beamer `\alert` in LaTeX reader. Closes #4091.
    * Docx reader: don't strip out empty paragraphs (#2252).
      Users who have a conversion pipeline from docx may want to consider adding
      `--strip-empty-paragraphs` to the command line.
    * Org reader (Albert Krewinkel): Allow empty list items (#4090).
    * Muse reader (Alexander Krotov):
      + Parse markup in definition list terms.
      + Allow definition to end with EOF.
      + Make code blocks round trip.
      + Drop common space prefix from list items.
      + Add partial round trip test.
      + Don't interpret XML entities.
      + Remove `nested`.
      + Parse `~~` as non-breaking space in Emacs mode.
      + Correctly remove indentation from notes.  Exactly one space is
      required and considered to be part of the marker.
      + Allow list items to be empty.
      + Add ordered list test.
      + Add more multiline definition tests.
      + Don't allow blockquotes within lists.
      + Fix reading of multiline definitions.
      + Add inline `<literal>` support.
      + Concatenate inlines of the same type
    * Docx writer: allow empty paragraphs (#2252).
    * CommonMark/gfm writer:
      + Use raw html for native divs/spans (#4113).  This allows a pandoc
      markdown native div or span to be rendered in gfm using raw html tags.
      + Implement `raw_html` and `raw_tex` extensions.  Note that `raw_html`
      is enabled by default for `gfm`, while `raw_tex` is disabled by default.
    * Muse writer (Alexander Krotov):
      + Test that inline math conversion result is normalized.
      Without normalization this test produced
      `<em>a</em><em>b</em><em>c</em>`.
      + Improve inline list normalization and move to writer.
      + Escape hash symbol.
      + Escape `----` to avoid accidental horizontal rules.
      + Escape only `</code>` inside code tag.
      + Additional `<verbatim>` is not needed as `<code>` is verbatim already.
    * LaTeX writer:
      + Allow specifying just width or height for image size.
      Previously both needed to be specified (unless the image was
      being resized to be smaller than its original size).
      If height but not width is specified, we now set width to
      textwidth. If width but not height is specified, we now set
      height to textheight.  Since we have `keepaspectratio`, this
      yields the desired result.
      + Escape `~` and `_` in code with `--listings` (#4111).
    * HTML writer: export `tagWithAttributes`.  This is a helper allowing
      other writers to create single HTML tags.
    * Let papersizes `a0`, `a1`, `a2`, ... be case-insensitive by
      converting the case as needed in LaTeX and ConTeXt writers.
    * Change `fixDisplayMath` from `Text.Pandoc.Writers.Shared`
      so that it no longer produces empty `Para`'s as an artifact.
    * `Text.Pandoc.Shared.blocksToInlines`:  rewrote using builder.
      This gives us automatic normalization, so we don't get
      for example two consecutive Spaces.
    * Include default CSS for 'underline' class in HTML-based templates.
    * revealjs template:  add `tex2jax` configuration for the
      math plugin.  With the next release of reveal.js, this will
      fix the problem of `$`s outside of math contexts being
      interpreted as math delimiters (#4027).
    * `pandoc.lua` module for use in lua filters (Albert Krewinkel):
      + Add basic lua List module (#4099, #4081).  The List module is
      automatically loaded, but not assigned to a global variable. It can be
      included in filters by calling `List = require 'List'`.  Lists of blocks,
      lists of inlines, and lists of classes are now given `List` as a metatable,
      making working with them more convenient.  E.g., it is now possible to
      concatenate lists of inlines using Lua's concatenation operator `..`
      (requires at least one of the operants to have `List` as a metatable):
      function Emph (emph)
      local s = {pandoc.Space(), pandoc.Str 'emphasized'}
      return pandoc.Span(emph.content .. s)
      end
      The `List` metatable is assigned to the tables which get passed to
      the constructors `MetaBlocks`, `MetaInline`, and `MetaList`. This
      enables the use of the resulting objects as lists.
      + `Lua/StackInstances`: push Pandoc and Meta via constructor.
      Pandoc and Meta elements are now pushed by calling the respective
      constructor functions of the pandoc Lua module. This makes serialization
      consistent with the way blocks and inlines are pushed to lua and allows
      to use List methods with the `blocks` value.
      + Add documentation for pandoc.List in `lua-filters.md`.
    * Use latest tagsoup.  This fixes a bug in parsing HTML tags with
      `&` (but not a valid entity) following them (#4094, #4088).
    * Use skylighting 0.4.4.1, fixing the color of unmarked code text
      when `numberLines` is used (#4103).
    * Make `normalizeDate` more forgiving (Mauro Bieg, #4101), not
      requiring a leading 0 on single-digit days.
    * Fix `--help` output for `--highlight-style` to include `FILE` (Mauro
      Bieg, #4095).
    * Clearer deprecation warning for `--latexmathml, --asciimathml, -m`.
      Previously we only mentioned `--latexmathml`, even if `-m` was
      used.
    * Changelog: fix description of lua filters in 2.0 release
      (Albert Krewinkel).  Lua filters were initially run *after* conventional
      (JSON) filters.  However, this was changed later to make it easier to deal
      with files in the mediabag. The changelog is updated to describe that
      feature of the 2.0 release correctly.
    * Change Generic JSON instances to TemplateHaskell (Jasper Van der Jeugt,
      [#4085]).  This reduces compile time and memory usage significantly.
    * `lua-filters.md`: Added tikz filter example.
    * Create alternative zip file for macOS binaries.
    * Create alternative zip file for Windows binaries.
    * Update INSTALL.md since we now provide zips for binaries.
    * Relax `http-types` dependency (Justus Sagemüller, #4084).
    * Add `epub.md`, `getting-started.md` to docs.  These used to live in
      the website repo.
    * Add `packages` target to Makefile.
    * Bump bounds for binary, http-types, tasty-hunit
    * Lua filters: preload text module (Albert Krewinkel, #4077).
      The `text` module is preloaded in lua. The module contains some UTF-8
      aware string functions, implemented in Haskell.  The module is loaded on
      request only, e.g.:
      text = require 'text'
      function Str (s)
      s.text = text.upper(s.text)
      return s
      end
    * Allow table-like access to attributes in lua filters (Albert Krewinkel,
      [#4071]).  Attribute lists are represented as associative lists in Lua. Pure
      associative lists are awkward to work with. A metatable is attached to
      attribute lists, allowing to access and use the associative list as if
      the attributes were stored in as normal key-value pair in table.
      Note that this changes the way `pairs` works on attribute lists. Instead
      of producing integer keys and two-element tables, the resulting iterator
      function now returns the key and value of those pairs.  Use `ipairs` to
      get the old behavior.  Warning: the new iteration mechanism only works if
      pandoc has been compiled with Lua 5.2 or later (current default: 5.3).
    * Text.Pandoc.Parsing.uri:  allow `&` and `=` as word characters (#4068).
      This fixes a bug where pandoc would stop parsing a URI with an
      empty attribute:  for example, `&a=&b=` wolud stop at `a`.
      (The uri parser tries to guess which punctuation characters
      are part of the URI and which might be punctuation after it.)
    * Introduce `HasSyntaxExtensions` typeclass (Alexander Krotov, #4074).
      + Added new `HasSyntaxExtensions` typeclass for `ReaderOptions` and
      `WriterOptions`.
      + Reimplemented `isEnabled` function from `Options.hs` to accept both
      `ReaderOptions` and `WriterOptions`.
      + Replaced `enabled` from `CommonMark.hs` with new `isEnabled`.
    * Add `amuse` extension (Alexander Krotov) to enable Amuse wiki
      behavior for `muse`.  New `Ext_amuse` constructor for
      `Extension`. Note: this is switched on by default; for
      Emacs behavior, use `muse-amuse`.
    * Muse reader (Alexander Krotov):
      + Count only one space as part of list item marker.
      + Produce SoftBreaks on newlines. Now wrapping can be preserved
      with `--wrap=preserve`.
      + Add Text::Amuse footnote extensions.  Footnote end is indicated by
      indentation, so footnotes can be placed anywhere in the text,
      not just at the end of it.
      + Accept Emacs Muse definition lists when `-amuse`.
      Emacs Muse does not require indentation.
    * HTML reader:
      + Ensure we don't produce level 0 headers (#4076), even for chapter
      sections in epubs.  This causes problems because writers aren't set
      up to expect these.
      + Allow spaces after `\(` and before `\)` with `tex_math_single_backslash`.
      Previously `\( \frac{1}{a} < \frac{1}{b} \)` was not parsed as math in
      `markdown` or `html` `+tex_math_single_backslash`.
      + Parse div with class `line-block` as LineBlock.
      + Don't fail with block-level content in figcaption (Mauro Bieg, #4183).
    * MANUAL: clarify that math extensions work with HTML.
      Clarify that `tex_math_dollars` and `tex_math_single_backslash`
      will work with HTML as well as Markdown.
    * Creole reader: Fix performance issue for longer lists (Sascha Wilde,
      [#4067]).
    * RST reader: better support for 'container' directive (#4066).
      Create a div, incorporate name attribute and classes.
    * LaTeX reader:
      + Support column specs like `*{2}{r}` (#4056).  This is equivalent to
      `rr`.  We now expand it like a macro.
      + Allow optional args for parbox (#4056).
      + Allow optional arguments on `\footnote` (#4062).
    * EPUB writer: Fixed path for cover image (#4069).  It was previously
      `media/media/imagename`, and should have been `media/imagename`.
    * Markdown writer: fix bug with doubled footnotes in grid tables
      (#4061).
    * LaTeX template:  include natbib/biblatex after polyglossia (#4073).
      Otherwise we seem to get an error; biblatex wants polyglossia
      language to be defined.
    * Added examples to lua filters documentation.
    * Deprecated ancient HTML math methods: `--latexmathml`, `--gladtex`,
      `--mimetex`, `--jsmath`.
    * Fixed URIs in `data/jats.csl`.  They were being rendered twice,
      leading to invalid XML in default JATS output with pandoc-citeproc.
    * `lua-filters.md`: use real-world man page filter as example.
    * Add lua filter functions `walk_inline` and `walk_block`
      in the pandoc module, to apply filters inside particular
      inline and block elements.
    * Refactored some code from `Text.Pandoc.Lua.PandocModule`
      into new internal module `Text.Pandoc.Lua.Filter`.
    * Markdown reader:
      + Allow fenced code blocks to be indented 1-3 spaces (#4011).
      This brings our handling of them into alignment with CommonMark's.
      + Fix YAML metadata with "chomp" (`|-`).  Previously if a
      YAML block under `|-` contained a blank line, pandoc would
      not parse it as metadata.
    * Removed `etc.` from abbreviations file.  Often `etc.` ends a
      sentence, and we want the period to be treated as a
      sentence-ending period.
    * Fix regression with `--metadata` (#4054).  Values specified with
      `--metadata` should replace a metadata value set in the document
      itself, rather than creating a list including a new value.
    * EPUB writer:
      + Fix EPUB OCF structure.  #3720 had been improperly implemented.
      + Fix modified paths for raw HTML tags (src, poster, etc.)
      (#4050, #4055). This had not been updated for the new EPUB
      container layout, with a separate text/ subdirectory.
      + Fix image paths with empty `--epub-subdirectory`.
    * Miscellaneous code cleanup (Alexander Krotov).
    * Use pandoc-types 1.17.3, which adds `Walkable` instances
      for `[Block] Block` and `[Inline] Inline`.
    * Remove obsolete `stack.full.yaml` (#4052).
    * Change to using pandoc-citeproc 0.12.1 in binary packages.
    * Consolidate math output method documentation (#4049, Mauro Bieg).
    * `MANUAL.txt`: fix header level of "Extension: emoji" (Albert Krewinkel).
    * Use lua filter to generate man page from `MANUAL.txt`, replacing old
      Haskell filters.  This is easier and faster.
    * Improved `INSTALL.md`.
    * Update commands to extract deb archive on Linux (#4043, Salim B).
    * Improved fix to #3989 (parsing of HTML tags containing
      `>` in an attribute or comment). The previous fix (in 2.0.1) only
      worked in certain cases.
    * FB2 writer (Alexander Krotov):
      + Add `unrecognised` genre to `<title-info>`
      (Alexander Krotov).  XML schema requires at least one genre.
      + Remove `<annotation>` from `<body>`.
    * CommonMark writer: fix strikethrough for `gfm` (#4038).
    * Use texmath 0.10, which adds support for a wider range of
      symbols and fixes default column alignments in MathML
      and OMML.
    * Highlighting fixes, using skylighting 0.4.3.2:
      + Fix invalid CSS.
      + Support `lineAnchors` (or `line-anchors`) in HTML code blocks.
      + Ensure that code lines don't get duplicate identifiers (#4031).
      The line identifiers are built using the code block's identifier
      as a prefix. If the code block has null identifier, we use
      `cb1`, `cb2`, etc.
    * Added a few abbreviations to `data/abbreviations`,
      and sorted the list (#3984, Wandmalfarbe).
    * Improved support for columns in HTML writer (#4028).
      + Remove `width` attribute from the `div`.
      + Remove space between `<div class="column">` elements,
      since this prevents columns whose widths sum to 100%
      (the space takes up space).
      + Move as much as possible of the CSS to the template.
      + Ensure that all the HTML-based templates (including epub)
      contain the CSS for columns.
      + Columns default to 50% width unless they are given a width
      attribute.  So if you want two equal-width columns, you
      can use a div with class `column` and no `width` attribute.
    * SelfContained: use `base64` for css links with media attribute (#4026).
      This fixes `--self-contained` with S5.
    * Improve `pandoc-template-mode.el` (Vaclav Haisman).
    * Issue INFO, not WARNING, when a .sty file cannot be
      read in LaTeX reader.  It is normally not an issue requiring
      a fix from the user if .sty files are not found.
    * INSTALL.md: MacOS instructions needed xar -f (adam234).
    * MANUAL.txt:
      + Clarify that --setext-headers doesn't affect gfm output (#4035).
      + Clarify what is needed to open and close a div in `fenced_divs`
      (#4039, Tristano Ajmone).
      + Removed reference to `default.beamer` in docs (#4024).
      Also added mention of other templates affecting PDF output
      with different settings.
    * Fixed regression in parsing of HTML comments in markdown and other
      non-HTML formats (`Text.Pandoc.Readers.HTML.htmlTag`) (#4019).
      The parser stopped at the first `>` character, even if it wasn't
      the end of the comment.
    * Creole reader (Sascha Wilde):
      + Fix some minor typos and formatting.
      + Add additional test on nowiki-block after para.
      + Fix lists with trailing white space.
    * LaTeX reader: handle `%` comment right after command.
      For example, `\emph%`.
    * Markdown reader:  make sure fenced div closers work in lists.
      Previously the following failed:
      ::: {.class}
      1. one
      2. two
      :::
      and you needed a blank line before the closing `:::`.
    * Make `fenced_divs` affect the Markdown writer.  If `fenced_divs` is
      enabled, Divs will be rendered as fenced divs.
    * LaTeX/Beamer writer: support "blocks" inside columns and other Divs
      (#4016).
    * HTML Writer: consistently use dashed class-names (Mauro Bieg, #3556).
      Note: this change may require some changes in CSS rules.
      `footnoteRef` has become `footnote-ref`, `titleslide` has
      become `title-slide`, and `footnoteBack` has become `footnote-back`.
    * JATS writer: Properly pass through author metadata (#4020).
    * FB2 writer (Alexander Krotov):
      + Write blocks outside of `<p>` in definitions.
      + Make bullet lists consistent with ordered lists, repeating
      the marker for the outer list rather than indenting sublists,
      since indentation does not work in readers.
      + Add new style FB2 tests.
    * `Text.Pandoc.ImageSize`: Add `Millimeter` constructor to `Dimension`
      (#4012) [API change]. Now sizes given in 'mm' are no longer converted
      to 'cm'.
    * Revise documentation of small caps syntax (Andrew Dunning, #4013).
    * Fix broken reference links in manual (Andrew Dunning, #4014)
    * Fixed example of slide columns structure in changelog (#4015).
      Also documented this feature in MANUAL.txt.
    * EPUB writer:
      + Fixed filepaths for nonstandard epub-subdirectory values.
      + Ensure that epub2 is recognized as a non-text format,
      so that a template is used.
      + Don't include "prefix" attribute for ibooks for epub2.
      It doesn't validate.
      + Fix stylesheet paths; previously we had an incorrect
      stylesheet path for the cover page and nav page.
    * LaTeX reader:
      + Insert space when needed in macro expansion (#4007).
      Sometimes we need to insert a space after a control sequence
      to prevent it merging with a following letter.
      + Allow unbraced arguments for macros (#4007).
      + Allow body of macro definition to be unbraced (#4007).
    * Linux package build: ensure that pandoc-citeproc is statically linked.
    * trypandoc: add native, ms.
    [new features]
    * New output format `ms` (groff ms). Complete support, including
      tables, math, syntax highlighting, and PDF bookmarks. The writer uses
      texmath's new eqn writer to convert math to eqn format, so a ms file
      produced with this writer should be processed with `groff -ms -e` if
      it contains math.
    * New output format `jats` (Journal Article Tag Suite).  This is an XML
      format used in archiving and publishing articles.  Note that a
      URI-encoded CSL stylesheet (`data/jats.csl`) is added automatically
      unless a stylesheet is specified using `--css`.
    * New output format `gfm` (GitHub-flavored CommonMark) (#3841).
      This uses bindings to GitHub's fork of cmark, so it should parse
      gfm exactly as GitHub does (excepting certain postprocessing
      steps, involving notifications, emojis, etc.).  `markdown_github`
      has been deprecated in favor of `gfm`.
    * New output format `muse` (Emacs Muse) (Alexander Krotov, #3489).
    * New input format `gfm` (GitHub-flavored CommonMark) (#3841).
      This uses bindings to GitHub's fork of cmark.  `markdown_github`
      has been deprecated in favor of `gfm`.
    * New input format `muse` (Emacs Muse) reader (Alexander Krotov, #3620).
    * New input format `tikiwiki` (TikiWiki markup) (rlpowell, #3800).
    * New input format `vimwiki` (Vimwiki markup) (Yuchen Pei, #3705).
      Note that there is a new data file, `data/vimwiki.css`, which can
      be used to display the HTML produced by this reader and
      pandoc's HTML writer in the style of vimwiki's own HTML
      export.
    * New input format `creole` (Creole 1.0) (#3994, Sascha Wilde).
    * New syntax for Divs, with `fenced_divs` extension enabled by
      default (#168).  This gives an attractive, plain-text way to create
      containers for block-level content.
    * Added new syntax for including raw content in any output format,
      enabled by the `raw_attribute` extension (which is on by default
      for `markdown` and `multimarkdown`).  The syntax is the same as
      for fenced code blocks or code inlines, only with `{=FORMAT}` for
      attributes, where `FORMAT` is the name of the output format
      (e.g., `ms`, `html`).
    * Implement multicolumn support for slide formats (#1710).
      The structure expected is:
      :::::::::::::: {.columns}
      ::: {.column width="40%"}
      contents...
      :::
      ::: {.column width="60%"}
      contents...
      :::
      ::::::::::::::
      Support has been added for beamer and all HTML slide formats.
    * Allows line comments in templates, beginning with `$--` (#3806).
      (Requires doctemplates 0.2.1.)
    * Add `--eol=crlf|lf|native` flag and writer option to control line endings
      (Stefan Dresselhaus, #3663, #2097).
    * Add `--log` option to save log messages in JSON format to a file (#3392).
    * Add `--request-header` option, to set request headers when pandoc
      makes HTTP requests to fetch external resources. For example:
      `--request-header User-Agent:blah`.
    * Added lua filters (Albert Krewinkel, #3514).  The new `--lua-filter`
      option works like `--filter` but takes pathnames of special lua filters
      and uses the lua interpreter baked into pandoc, so that no external
      interpreter is needed.  Note that lua filters are all applied before
      regular filters, regardless of their position on the command line.
      For documentation of lua filters, see `doc/lua-filters.md`.
    * Set `PANDOC_READER_OPTIONS` in environment where filters are run.
      This contains a JSON representation of `ReaderOptions`, so filters
      can access it.
    * Support creation of pdf via groff `ms` and pdfroff.
      `pandoc -t ms -o output.pdf input.txt`.
    * Support for PDF generation via HTML and `weasyprint` or `prince`
      (Mauro Bieg, #3909).  `pandoc -t html5 -o output.pdf --pdf-engine=prince`.
    * Added `--epub-subdirectory` option (#3720).  This specifies the
      subdirectory in the OCF container that holds the EPUB specific content.
      We now put all EPUB related content in an `EPUB/` subdirectory by default
      (later this will be configurable).
      ```
      mimetype
      META-INF/
      com.apple.ibooks.display-options.xml
      container.xml
      EPUB/ <<--configurable-->>
      fonts/ <<--static-->>
      font.otf
      media/ <<--static-->>
      cover.jpg
      fig1.jpg
      styles/ <<--static-->>
      stylesheet.css
      content.opf
      toc.ncx
      text/ <<--static-->>
      ch001.xhtml
      ```
    * Added `--resource-path=SEARCHPATH` command line option (#852).
      SEARCHPATH is separated by the usual character, depending on OS
      (: on unix, ; on windows).  Default resource path is just working
      directory.  However, the working directory must be explicitly
      specified if the `--resource-path` option is used.
    * Added `--abbreviations=FILE` option for custom abbreviations file
      (#256).  Default abbreviations file (`data/abbreviations`) contains
      a list of strings that will be recognized by pandoc's
      Markdown parser as abbreviations.  (A nonbreaking space will
      be inserted after the period, preventing a sentence space in
      formats like LaTeX.) Users can override the default by putting a file
      abbreviations in their user data directory (`~/.pandoc` on *nix).
    * Allow a theme file as argument to `--highlight-style`.
      Also include a sample, `default.theme`, in `data/`.
    * Allow `--syntax-definition` option for dynamic loading of syntax
      highlighting definitions (#3334).
    * Lists in `markdown` by default now use the CommonMark variable
      nesting rules (#3511). The indentation required for a block-level
      item to be included in a list item is no longer fixed, but is
      determined by the first line of the list item.  To be included in
      the list item, a block must be indented to the level of the first
      non-space content after the list marker. Exception: if are 5 or more
      spaces after the list marker, then the content is interpreted as an
      indented code block, and continuation paragraphs must be indented
      two spaces beyond the end of the list marker.  See the CommonMark
      spec for more details and examples.
      Documents that adhere to the four-space rule should, in most cases,
      be parsed the same way by the new rules.  Here are some examples
      of texts that will be parsed differently:
    - a
    - b
      will be parsed as a list item with a sublist; under the four-space
      rule, it would be a list with two items.
    - a
      code
      Here we have an indented code block under the list item, even though it
      is only indented six spaces from the margin, because it is four spaces
      past the point where a continuation paragraph could begin.  With the
      four-space rule, this would be a regular paragraph rather than a code
      block.
    - a
      code
      Here the code block will start with two spaces, whereas under
      the four-space rule, it would start with `code`.  With the four-space
      rule, indented code under a list item always must be indented eight
      spaces from the margin, while the new rules require only that it
      be indented four spaces from the beginning of the first non-space
      text after the list marker (here, `a`).
      This change was motivated by a slew of bug reports from people
      who expected lists to work differently (#3125, #2367, #2575, #2210,
      [#1990], #1137, #744, #172, #137, #128) and by the growing prevalance
      of CommonMark (now used by GitHub, for example).  Those who
      prefer the old behavior can use `-f markdown+four_space_rule`.
    * Added `four_space_rule` extension.  This triggers the old pandoc
      parsing rule for content nested under list items (the "four space
      rule").
    * Added `spaced_reference_links` extension (#2602).  It allows whitespace
      between the two parts of a reference link:  e.g.
      [a] [b]
      [b]: url
      This was previously enabled by default; it is now forbidden by default.
    * Add `space_in_atx_header` extension (#3512).  This is enabled by default
      in pandoc and GitHub markdown but not the other flavors.
      This requires a space between the opening #'s and the header
      text in ATX headers (as CommonMark does but many other implementations
      do not).  This is desirable to avoid falsely capturing things like
      [#]hashtag
      or
      [#5]
    * Add `sourcefile` and `outputfile` template variables (Roland Hieber,
      [#3431]).
    * Allow ibooks-specific metadata in epubs (#2693).  You can now have
      the following fields in your YAML metadata, and it will be treated
      appropriately in the generated EPUB:
      ```
      ibooks:
      version: 1.3.4
      specified-fonts: false
      ipad-orientation-lock: portrait-only
      iphone-orientation-lock: landscape-only
      binding: true
      scroll-axis: vertical
      ```
    [behavior changes]
    * Reader functions no longer presuppose that CRs have been
      stripped from the input. (They strip CRs themselves, before
      parsing, to simplify the parsers.)
    * Added support for translations (localization) (#3559).
      Currently this only affects the LaTeX reader, for things
      like `\figurename`.  Translation data files for 46 languages
      can be found in `data/translations`.
    * Make `--ascii` work with DocBook output too.
    * Rename `--latex-engine` to `--pdf-engine`,
      and `--latex-engine-opt` to `--pdf-engine-opt`.
    * Removed `--parse-raw` and `readerParseRaw`.  These were confusing.
      Now we rely on the `+raw_tex` or `+raw_html` extension with latex or html
      input.  Thus, instead of `--parse-raw -f latex` we use `-f latex+raw_tex`,
      and instead of `--parse-raw -f html` we use `-f html+raw_html`.
    * With `--filter` R filters are now recognized, even if they are
      not executable (#3940, #3941, Andrie de Vries).
    * Support SVG in PDF output, converting with `rsvg2pdf` (#1793).
    * Make epub an alias for epub3, not epub2.
    * Removed `--epub-stylesheet`; use `--css` instead (#3472, #847).
      Multiple stylesheets may be used.  Stylesheets will be taken both from
      `--css` and from the `stylesheet` metadata field (which can contain
      either a file path or a list of them).
    * `--mathml` and MathML in HTMLMathMethod no longer take an argument.
      The argument was for a bridge JavaScript that used to be necessary
      in 2004.  We have removed the script already.
    * `--katex` improvements.  The latest version is used, and the
      autoload script is loaded by default.
    * Change MathJax CDN default since old one is shutting down (#3544).
      Note:  The new URL requires a version number, which we'll have
      to update manually in subsequent pandoc releases in order to
      take advantage of mathjax improvements.
    * `--self-contained`: don't incorporate elements with `data-external="1"`
      (#2656).  You can leave an external link as it is by adding the attribute
      data-external="1" to the element.  Pandoc will then not try to
      incorporate its content when `--self-contained` is used.  This is
      similar to a feature already supported by the EPUB writer.
    * Allow `--extract-media` to work with non-binary input formats
      (#1583, #2289).  If `--extract-media` is supplied with a non-binary
      input format, pandoc will attempt to extract the contents of all
      linked images, whether in local files, data: uris, or external uris.
      They will be named based on the sha1 hash of the contents.
    * Make `papersize: a4` work regardless of the case of `a4`.
      It is converted to `a4` in LaTeX and `A4` in ConTeXt.
    * Make `east_asian_line_breaks` affect all readers/writers (#3703).
    * Underlined elements are now treated consistently by readers
      (#2270, hftf); they are always put in a Span with class `underline`.
      This allows the user to treat them differently from other emphasis,
      using a filter.  Docx, Org, Textile, Txt2Tags, and HTML readers
      have been changed.
    * Improved behavior of `auto_identifiers` when there are explicit ids
      (#1745).  Previously only autogenerated ids were added to the list
      of header identifiers in state, so explicit ids weren't taken
      into account when generating unique identifiers.  Duplicated
      identifiers could result.  This simple fix ensures that explicitly given
      identifiers are also taken into account.
    * Use `table-of-contents` for contents of toc, make `toc` a boolean
      (#2872).  Changed markdown, rtf, and HTML-based templates accordingly.
      This allows you to set `toc: true` in the metadata; this
      previously produced strange results in some output formats.
      For backwards compatibility, `toc` is still set to the
      toc contents.  But it is recommended that you update templates
      to use `table-of-contents` for the toc contents and `toc`
      for a boolean flag.
    * Change behavior with binary format output to stdout.
      Previously, for binary formats, output to stdout was disabled
      unless we could detect that the output was being piped (and not
      sent to the terminal).  Unfortunately, such detection is not
      possible on Windows, leaving windows users no way to pipe binary
      output.  So we have changed the behavior in the following way:
      + Output to stdout is allowed when it can be determined that
      the output is being piped (on non-Windows platforms).
      + If the `-o` option is not used, binary output is never sent
      to stdout by default; instead, an error is raised.
      + If `-o -` is used, binary output is sent to stdout, regardless
      of whether it is being piped. This works on Windows too.
    * Better error behavior:  uses of `error` have been replaced by
      raising of `PandocError`, which can be trapped and handled by the
      calling program.
    * Removed `hard_line_breaks` extension from `markdown_github` (#3594).
      GitHub has two Markdown modes, one for long-form documents like READMEs
      and one for short things like issue coments. In issue comments, a line
      break is treated as a hard line break. In README, wikis, etc., it is
      treated as a space as in regular Markdown.  Since pandoc is more likely to
      be used to convert long-form documents from GitHub Markdown,
      `-hard_line_breaks` is a better default.
    * Include `backtick_code_blocks` extension in `mardkown_mmd` (#3637).
    * Escape `MetaString` values (as added with `-M/--metadata` flag) (#3792).
      Previously they would be transmitted to the template without any
      escaping.  Note that `--M title='*foo*'` yields a different result from
    - --
      title: *foo*
    - --
      In the latter case, we have emphasis; in the former case, just
      a string with literal asterisks (which will be escaped
      in formats, like Markdown, that require it).
    * Allow `em`, `cm`, `in` for image height/width in HTML, LaTeX (#3450).
    * HTML writer: Insert `data-` in front of unsupported attributes.  Thus,
      a span with attribute `foo` gets written to HTML5 with `data-foo`, so
      it is valid HTML5.  HTML4 is not affected.  This will allow us to use
      custom attributes in pandoc without producing invalid HTML. (With help
      from Wandmalfarbe, #3817.)
    * Plain writer:  improved super/subscript rendering.  We now
      handle more non-digit characters for which there are
      sub/superscripted unicode characters.  When unicode
      sub/superscripted characters are not available, we use
      `_(..)` or `^(..)` (#3518).
    * Docbook, JATS, TEI writers: print INFO message when omitting interior
      header (#3750).  This only applies to section headers inside list items,
      e.g., which were otherwise silently omitted.
    * Change to `--reference-links` in Markdown writer (#3701).  With
      `--reference-location` of `section` or `block`, pandoc will now repeat
      references that have been used in earlier sections.  The Markdown
      reader has also been modified, so that *exactly* repeated references
      do not generate a warning, only references with the same label but
      different targets.  The idea is that, with references after every block,
      one might want to repeat references sometimes.
    * ODT/OpenDocument writer:
      + Support `lang` attribute (#1667).
      + Added support for `--toc` (#2836).  Thanks to @anayrat.
    * Docx writer:
      + `lang` meta, see #1667 (Mauro Bieg, #3515).
      + Change `FigureWithCaption` to `CaptionedFigure` (iandol, #3658).
      + Use `Table` rather than `Table Normal` for table style (#3275).
      `Table Normal` is the default table style and can't be modified.
      + Pass through comments (#2994).  We assume that comments are defined as
      parsed by the docx reader:
      I want <span class="comment-start" id="0" author="Jesse Rosenthal"
      date="2016-05-09T16:13:00Z">I left a comment.</span>some text to
      have a comment <span class="comment-end" id="0"></span>on it.
      We assume also that the id attributes are unique and properly
      matched between comment-start and comment-end.
      + Bookmark improvements.  Bookmark start/end now surrounds content rather
      than preceding it.  Bookmarks generated for Div with id
      (jgm/pandoc-citeproc#205).
      + Add `keywords` metadata to docx document properties (Ian).
    * RST writer: support unknown interpreted text roles by
      parsing them as `Span` with `role` attributes (#3407).  This
      way they can be manipulated in the AST.
    * HTML writer:
      + Line block: Use class instead of style attribute (#1623).  We now
      issue `<div class="line-block">` and include a default definition
      for `line-block` in the default templates, instead of hard-coding a
      `style` on the div.
      + Add class `footnoteBack` to footnote back references (Timm Albers).
      This allows for easier CSS styling.
      + Render SmallCaps as span with smallcaps class (#1592), rather than
      using a style attribute directly.  This gives the user more flexibility
      in styling small caps in CSS.
      + With reveal.js we use `data-src` instead of `src` for images for
      lazy loading.
      + Special-case `.stretch` class for images in reveal.js (#1291).
      Now in reveal.js, an image with class `stretch` in a paragraph
      by itself will stretch to fill the whole screen, with no
      caption or figure environment.
    * Added warnings for non-rendered blocks to writers.
    * Writers now raise an error on template failure.
    * When creating a PDF via LaTeX, warn if the font is missing some
      characters (#3742).
    * Remove initial check for PDF-creating program (#3819).
      Instead, just try running it and raise the exception if it
      isn't found at that point.  This improves things for users of Cygwin
      on Windows, where the executable won't be found by `findExecutable`
      unless `.exe` is added.  The same exception is raised as before, but
      at a later point.
    * Readers issue warning for duplicate header identifiers (#1745).
      Autogenerated header identifiers are given suffixes so as not to clash
      with previously used header identifiers. But they may still coincide with
      an explicit identifier that is given for a header later in the document,
      or with an identifier on a div, span, link, or image. We now issue
      a warning in this case, so users can supply an explicit identifier.
    * CommonMark reader now supports `emoji`, `hard_line_breaks`, `smart`,
      and `raw_html` extensions.
    * Markdown reader:
      + Don't allow backslash + newline to affect block structure (#3730).
      Note that as a result of this change, the following, which formerly
      produced a header with two lines separated by a line break, will
      now produce a header followed by a paragraph:
      [#] Hi\
      there
      This may affect some existing documents that relied on
      this undocumented and unintended behavior.  This change makes pandoc
      more consistent with other Markdown implementations, and with itself
      (since the two-space version of a line break doesn't work inside ATX
      headers, and neither version works inside Setext headers).
    * Org reader (Albert Krewinkel, unless noted):
      + Support `table.el` tables (#3314).
      + Support macros (#3401).
      + Support the `#+INCLUDE:` file inclusion mechanism (#3510).
      Recognized include types are `example`, `export`, `src`, and
      normal org file inclusion.  Advanced features like line numbers
      and level selection are not implemented yet.
      + Interpret more meta value as inlines.  The values of the following
      meta variables are now interpreted using org-markup instead of
      treating them as pure strings: `keywords` (comma-separated list of
      inlines), `subtitle` (inline values), `nocite` (inline values, can
      be repeated).
      + Support `\n` export option (#3940).  This turns all newlines in the
      text into hard linebreaks.
    * RST reader:
      + Improved admonition support (#223).  We no longer add an
      `admonition` class, we just use the class for the type of admonition,
      `note` for example.  We put the word corresponding to the label in
      a paragraph inside a `Div` at the beginning of the admonition with
      class `admonition-title`.  This is about as close as we can get to
      RST's own output.
      + Initial support of `.. table` directive.  This allows adding captions
      to tables.
      + Support `.. line-block` directive.  This is deprecated but may still
      be in older documents.
      + Support scale and align attributes of images (#2662).
      + Implemented implicit internal header links (#3475).
      + Support RST-style citations (#853).  The citations appear at the end
      of the document as a definition list in a special div with id
      `citations`. Citations link to the definitions.
      + Recurse into bodies of unknown directives (#3432).
      In most cases it's better to preserve the content than
      to emit it.  This isn't guaranteed to have good results;
      it will fail spectacularly for unknown raw or verbatim directives.
      + Handle chained link definitions (#262).  For example,
      .. _hello:
      .. _goodbye: example.com
      Here both `hello` and `goodbye` should link to `example.com`.
      + Support anchors (#262).  E.g.
      `hello`
      .. _hello:
      paragraph
      This is supported by putting "paragraph" in a `Div` with id `hello`.
      + Support `:widths:` attribute for table directive.
      + Implement csv-table directive (#3533).  Most attributes are supported,
      including `:file:` and `:url:`.
      + Support unknown interpreted text roles by parsing them as Span
      with "role" attributes (#3407).  This way they can be manipulated in
      the AST.
    * HTML reader: parse a span with class `smallcaps` as `SmallCaps`.
    * LaTeX reader:
      + Implemented `\graphicspath` (#736).
      + Properly handle column prefixes/suffixes.  For example, in
      `\begin{tabular}{>{$}l<{$}>{$}l<{$} >{$}l<{$}}`
      each cell will be interpreted as if it has a `$`
      before its content and a `$` after (math mode).
      + Handle komascript `\dedication` (#1845).  It now adds a
      `dedication` field to metadata.  It is up to the user to supply
      a template that uses this variable.
      + Support all `\textXX` commands, where XX = `rm`, `tt`, `up`, `md`,
      `sf`, `bf` (#3488).  Spans with a class are used when there is
      nothing better.
      + Expand `\newenvironment` macros (#987).
      + Add support for LaTeX subfiles package (Marc Schreiber, #3530).
      + Better support for subfigure package (#3577).
      A figure with two subfigures turns into two pandoc
      figures; the subcaptions are used and the main caption
      ignored, unless there are no subcaptions.
      + Add support for \vdots (Marc Schreiber, #3607).
      + Add basic support for hyphenat package (Marc Schreiber, #3603).
      + Add basic `\textcolor` support (Marc Schreiber).
      + Add support for `tabularx` environment (Marc Schreiber, #3632).
      + Better handling of comments inside math environments (#3113).
      This solves a problem with commented out `\end{eqnarray}` inside
      an eqnarray (among other things).
      + Parse tikzpicture as raw verbatim environment if `raw_tex` extension
      is selected (#3692).  Otherwise skip with a warning.  This is better
      than trying to parse it as text!
      + Add `\colorbox` support (Marc Schreiber).
      + Set identifiers on Spans used for `\label`.
      + Have `\setmainlanguage` set `lang` in metadata.
      + Support etoolbox's `\ifstrequal`.
      + Support `plainbreak`, `fancybreak` et al from the memoir class
      (bucklereed, #3833).
      + Support `\let`.  Also, fix regular macros so they're expanded at the
      point of use, and NOT also the point of definition.  `\let` macros,
      by contrast, are expanded at the point of definition.  Added an
      `ExpansionPoint` field to `Macro` to track this difference.
      + Support simple `\def` macros.  Note that we still don't support
      macros with fancy parameter delimiters, like `\def\foo#1..#2{...}`.
      + Support \chaptername, \partname, \abstractname, etc.  (#3559,
      obsoletes #3560).
      + Put content of `\ref`, `\label`, `\eqref` commands into `Span` with
      attributes, so they can be handled in filters (Marc Schreiber, #3639)
      + Add Support for `glossaries` and `acronym` package (Marc Schreiber,
      [#3589]). Acronyms are not resolved by the reader, but acronym and
      glossary information is put into attributes on Spans so that they
      can be processed in filters.
      + Use `Link` instead of `Span` for `\ref`.  This makes more sense
      semantically and avoids unnecessary `Span [Link]` nestings when
      references are resolved.
      + Rudimentary support for `\hyperlink`.
      + Support `\textquoteleft|right`, `\textquotedblleft|right` (#3849).
      + Support `\lq`, `\rq`.
      + Implement `\newtoggle`, `\iftoggle`, `\toggletrue|false` from etoolbox
      (#3853).
      + Support `\RN` and `\Rn`, from biblatex (bucklereed, #3854).
      + Improved support for `\hyperlink`, `\hypertarget` (#2549).
      + Support `\k` ogonek accent.
      + Improve handling of accents.  Handle ogonek, and fall back correctly
      with forms like `\"{}`.
      + Better support for ogonek accents.
      + Support for `\faCheck` and `\faClose` (Marc Schreiber, #3727).
      + Support for `xspace` (Marc Schreiber, #3797).
      + Support `\setmainlanguage` or `\setdefaultlanguage` (polyglossia)
      and `\figurename`.
      + Better handling of `\part` in LaTeX (#1905).  Now we parse chapters as
      level 0 headers, and parts as level -1 headers.  After parsing, we
      check for the lowest header level, and if it's less than 1 we bump
      everything up so that 1 is the lowest header level.  So `\part` will
      always produce a header; no command-line options are needed.
      + Add block version of `\textcolor` (Marc Schreiber).
      + `\textcolor` works as inline and block command (Marc Schreiber).
      + `\textcolor` will be parse as span at the beginning of a paragraph
      (Marc Schreiber).
      + Read polyglossia/babel `\text(LANG){...}` (bucklereed)
      + Improved handling of include files in LaTeX reader (#3971).
      Previously `\include` wouldn't work if the included file
      contained, e.g., a begin without a matching end.
      + Support `\expandafter` (#3983).
      + Handle `\DeclareRobustCommand` (#3983).  Currently it's just treated
      as a synonym for `\newcommand`.
      + Handle `\lettrine` (Mauro Bieg).
    * Math improvements due to updates in texmath:
      + Improved handling of accents and upper/lower delimiters.
      + Support for output in GNU eqn format (used with *roff).
      + Allow `\boldsymbol` + a token without braces, and similarly
      with other styling commands.
      + Improve parsing of `\mathop` to allow multi-character operator names.
      + Add thin space after math operators when "faking it with
      unicode."
    * `walk` is now used instead of `bottomUp` in the `ToJSONFilter`
      instance for `a -> [a]` (pandoc-types).  Note that behavior
      will be slightly different, since `bottomUp`'s treatment of
      a function `[a] -> [a]` is to apply it to each sublist of a
      list, while walk applies it only to maximal sublists.
      Usually the latter behavior is what is wanted, and the
      former can be simulated when needed.  But there may be
      existing filters that need to be rewritten in light of the
      new behavior.  Performance should be improved.
    * There are some changes to syntax highlighting due to revisions
      in the `skylighting` library:
      + Support for `powershell` has been added, and many syntax
      definitions have been updated.
      + Background colors have been added to the `kate` style.
      + The way highlighted code blocks are formatted in HTML has
      been changed (David Baynard), in ways that may require
      changes in hard-coded CSS affecting highlighting.
      (If you haven't included hard-coded highlighting CSS in
      your template, you needn't change anything.)
    [API changes]
    * New module `Text.Pandoc.Class` (Jesse Rosenthal, John MacFarlane).
      This contains definitions of the `PandocMonad` typeclass, the
      `PandocIO` and `PandocPure` monads, and associated functions.
    * Changed types of all writers and readers.
      + We now use `Text` instead of `String` in the interface (#3731).
      (We have not yet changed the internals of most readers to work
      with `Text`, but making this change in the API now opens up a
      path to doing that.)
      + The result is now of form `m a` with constraint `PandocMonad m`.
      Readers and writers can be combined to form monadic values which
      can be run using either `runIO` or `runPure`.  If `runIO` is used,
      then both readers and writers will be able to do IO when needed
      (for include files, for example); if `runPure` is used,
      then the functions are pure and will not touch IO.
      + Where previously you used
      `writeRST def (readMarkdown def "[foo](url)")`, now you
      would use
      `runPure $ readMarkdown def (pack "[foo](url)") >>= writeRST def`.
    * New module `Text.Pandoc.Readers` (Albert Krewinkel).  This
      contains reader helper functions formerly defined in the
      top-level `Text.Pandoc` module.
      + Changed `StringReader` -> `TextReader`.
      + `getReader` now returns a pair of a reader and
      `Extensions`, instead of building the extensions into the
      reader (#3659).  The calling code must explicitly set
      `readerExtensions` using the `Extensions` returned.  The
      point of the change is to make it possible for the calling
      code to determine what extensions are being used.
    * New module `Text.Pandoc.Writers` (Albert Krewinkel).
      This contains writer helper functions formerly defined in the
      top-level `Text.Pandoc` module.
      + Changed `StringWriter` -> `TextWriter`.
      + `getWriter` now retuns a pair of a reader and
      `Extensions`, instead of building the extensions into the
      reader (#3659).  The calling code must explicitly set
      `readerExtensions` using the `Extensions` returned.  The
      point of the change is to make it possible for the calling
      code to determine what extensions are being used.
    * New module `Text.Pandoc.Lua`, exporting `runLuaFilter` (Albert Krewinkel,
      [#3514]).
    * New module `Text.Pandoc.App`.  This abstracts out the functionality
      of the command line program (`convertWithOpts`), so it can be reproduced
      e.g. in a desktop or web application.  Instead of exiting, we throw errors
      (#3548), which are caught (leading to exit) in pandoc.hs, but allow other
      users of `Text.Pandoc.App` to recover.  `pandoc.hs` is now a 2-liner.
      The module also exports some utility functions for parsing options
      and running filters.
    * New module `Text.Pandoc.Logging` (exported module) (#3392).
      This now contains the `Verbosity` definition previously in
      `Text.Pandoc.Options`, as well as a new `LogMessage` datatype that will
      eventually be used instead of raw strings for warnings.  This will enable
      us, among other things, to provide machine-readable warnings if desired.
      Include ToJSON instance and showLogMessage.  This gives us the possibility
      of both machine-readable and human-readable output for log messages.
    * New module `Text.Pandoc.BCP47`, with `getLang`, `Lang(..)`, `parseBCP47`.
    * New module `Text.Pandoc.Translations`, exporting `Term`,
      `Translations`, `readTranslations`.
    * New module `Text.Pandoc.Readers.LaTeX.Types', exporting `Macro`, `Tok`,
      `TokType`, `Line`, `Column`.
    * `Text.Pandoc.Error`: added many new constructors for `PandocError`.
    * Expose some previously private modules (#3260).  These are often
      helpful to people writing their own reader or writer modules:
      + `Text.Pandoc.Writers.Shared`
      + `Text.Pandoc.Parsing`
      + `Text.Pandoc.Asciify`
      + `Text.Pandoc.Emoji`
      + `Text.Pandoc.ImageSize`
      + `Text.Pandoc.Highlighting`
    `
    * New module `Text.Pandoc.Extensions` (Albert Krewinkel):
      Extension parsing and processing functions were defined in the top-level
      `Text.Pandoc` module.  These functions are moved to the Extensions
      submodule as to enable reuse in other submodules.
    * Add `Ext_raw_attribute` constructor for `Extension`.
    * Add `Ext_fenced_divs` constructor for `Extension'.
    * Add `Ext_four_space_rule` constructor in `Extension`.
    * Add `Ext_gfm_auto_identifiers` constructor for `Extension`.
    * Add `Monoid` instance for `Extensions`.
    * Add `Text.Pandoc.Writers.Ms`, exporting `writeMs`.
    * Add `Text.Pandoc.Writers.JATS`, exporting `writeJATS`.
    * Add `Text.Pandoc.Writers.Muse`, exporting `writeMuse`.
    * Add `Text.Pandoc.Readers.Muse`, exporting `readMuse`.
    * Add `Text.Pandoc.Readers.TikiWiki`, exporting `readTikiWiki`.
    * Add `Text.Pandoc.Readers.Vimwiki`, exporting `readVimwiki`.
    * Add `Text.Pandoc.Readers.Creole`, exporting `readCreole`.
    * Export `setVerbosity` from `Text.Pandoc`.
    * `Text.Pandoc.Pretty`: Add `Eq` instance for `Doc`.
    * `Text.Pandoc.XML`: `toEntities`: changed type to `Text -> Text`.
    * `Text.Pandoc.UTF8`:
      + Export `fromText`, `fromTextLazy`, `toText`, `toTextLazy`.
      Define `toString`, `toStringLazy` in terms of them.
      + Add new functions parameterized on `Newline`: `writeFileWith`,
      `putStrWith`, `putStrLnWith`, `hPutStrWith`, `hPutStrLnWith`.
    * `Text.Pandoc.MediaBag`: removed `extractMediaBag`.
    * `Text.Pandoc.Highlighting`:
      + `highlighting` now returns an Either rather than Maybe.
      This allows us to display error information returned by the skylighting
      library.  Display a warning if the highlighting library throws an error.
      + Add parameter for `SyntaxMap` to `highlight`.
    * `Text.Pandoc.Writers.Math`:
      + Export `defaultMathJaxURL`, `defaultKaTeXURL`.  This will ensure that
      we only need to update these in one place.
    * `Text.Pandoc.SelfContained`:
      + Removed `WriterOptions` parameter from `makeSelfContained`.
      + Put `makeSelfContained` in PandocMonad instead of IO.  This removes
      the need to pass MediaBag around and improves exceptions.  It also
      opens up the possibility of using makeSelfContained purely.
      + Export `makeDataURI`.
    * `Text.Pandoc.ImageSize`:
      + Export `lengthToDim`, new function `scaleDimension`.
      + Export `inEm` from ImageSize (#3450).
      + Change `showFl` and `show` instance for `Dimension` so
      extra decimal places are omitted.
      + Added `Em` as a constructor of `Dimension`.
      + Add `WriterOptions` parameter to `imageSize` signature (Mauro Bieg).
    * `Text.Pandoc.Templates`:
      + Change type of `renderTemplate'`.  Now it runs in `PandocMonad`
      and raises a proper `PandocTemplateError` if there are problems, rather
      than failing with uncatchable `error`.
      + Change signature of `getDefaultTemplate`.  Now it runs in any instance
      of `PandocMonad`, and returns a `String` rather than an `Either` value.
      And it no longer takes a `datadir` parameter, since this can be
      retrieved from `CommonState`.
    * `Text.Pandoc.Options`:
      + Added `writerEpubSubdirectory` to `WriterOptions` (#3720).
      The EPUB writer now takes its EPUB subdirectory from this option.
      + In `WriterOptions`, rename `writerLaTeXEngine` to `writerPdfEngine`
      and `writerLaTeXArgs` to `writerPdfArgs` (Mauro Bieg, #3909).
      + Add `writerSyntaxMap` to `WriterOptions`.
      + Removed `writerEpubStylesheet` from `WriterOptions`.
      + Remove `writerUserDataDir` from `WriterOptions`.  It is now carried
      in `CommonState` in `PandocMonad` instances.  (And thus it can be used
      by readers too.)
      + Changed `writerEpubMetadata` to a `Maybe String`.
      + Removed `readerApplyMacros` from `ReaderOptions`.  Now we just check
      the `latex_macros` reader extension.
      + FromJSON/ToJSON instances for `ReaderOptions`.
      + In `HTMLMathMethod`, the `KaTeX` contsructor now takes only
      one string (for the KaTeX base URL), rather than two.
      + Removed `writerSourceURL` from `WriterOptions`.  We now use
      `stSourceURL` in `CommonState`, which is set by `setInputFiles`.
    * `Text.Pandoc.Shared`:
      + `tabFilter` now takes a `Text`, not `String`.
      + `openURL`: Changed type from an Either.  Now it will just raise
      an exception to be trapped later.
      + Remove `normalizeSpaces` (#1530).
      + Remove `warn`.  (Use `report` from `Text.Pandoc.Class` instead.)
      + Export a new function `crFilter`.
      + Add `eastAsianLineBreakFilter` (previously in Markdown reader).
      + Provide custom `isURI` that rejects unknown schemes.
      (Albert Krewinkel, #2713).  We also export the set of known
      `schemes`.  The new function replaces the function of the same name
      from `Network.URI`, as the latter did not check whether a scheme is
      well-known.  All official IANA schemes (as of 2017-05-22) are
      included in the set of known schemes.  The four non-official schemes
      `doi`, `isbn`, `javascript`, and `pmid` are kept.
      + Remove `err`.
      + Remove `readDataFile`, `readDefaultDataFile`, `getReferenceDocx`,
      `getReferenceODT`. These now live in `Text.Pandoc.Class`,
      where they are defined in terms of `PandocMonad`
      primitives and have different signatures.
      + Remove `openURL`.  Use `openURL` from `Text.Pandoc.Class` instead.
      + Add `underlineSpan`.
    * `Text.Pandoc.Readers.HTML`: export new `NamedTag` class.
    * `Text.Pandoc.Readers.Markdown`: remove `readDocxWithWarnings`.
      With the new API one can simply use `getLog` after running
      the reader.
    * `Text.Pandoc.Readers.LaTeX`: Changed types for `rawLaTeXInline`
      and `rawLaTeXBlock`.  (Both now return a `String`, and they are
      polymorphic in state.)
    [bug fixes and under-the-hood improvements]
    * TEI writer: Added identifiers on `<div>` elements.
    * DokuWiki reader: Better handling for code block in list item (#3824).
    * Custom writer: Remove old preprocesesor conditionals (Albert Krewinkel).
    * ZimWiki writer: Removed internal formatting from note and table cells,
      because ZimWiki does not support it (Alex Ivkin, #3446).
    * MediaWiki writer:
      + Updated list of syntax highlighting languages (#3461).
      Now `r` gets you `<source>` rather than `<code>` (among others).
      + Add display attribute on `<math>` tags (#3452).  This allows display
      math to be rendered properly.
      + Remove newline before `</ref>` (#2652).
      + Don't softbreak lines inside list items (#3531).
    * Org writer:
      + Reduce to two spaces after bullets (#3417, Albert Krewinkel).
      + Add unit tests (Alexander Krotov).
      + Stop using raw HTML to wrap divs (Albert Krewinkel, #3771).
      + Do not strip `#` from Org anchor links (Alexander Krotov).
    * CommonMark writer:
      + Avoid excess blank lines at end of output.
      + Prefer pipe tables to HTML tables even if it means losing relative
      column width information (#3734).
      + Support table, strikethrough extensions, when enabled (as with gfm).
      Note that we bypass the commonmark writer from cmark and construct our
      own pipe tables, with better results.
      + Properly support `--wrap=none`.
      + Use smallcaps class for `SmallCaps` (#1592).
      + Omit "fig:" prefix in image titles.  This is used internally to
      indicate internal figures.
    * RST writer:
      + Properly handle table captions.
      + Don't wrap lines in in definition list terms.  Wrapping is not allowed.
      + Implemented `+/-smart` and improved escaping with `+smart`.
      + Add empty comments when needed to avoid including a blockquote
      in the indented content of a preceding block (#3675).
      + Improve grid table output, fix bug with empty rows (#3516).
      Uses the new `gridTable` in Writers.Shared, which is here
      improved to better handle 0-width cells.
      + Remove space at beginning/end of RST code span (#3496).  Otherwise
      we get invalid RST.  There seems to be no way to escape the space.
      + Add header anchors when header has non-standard id (#3937).
      + Correctly handle inline code containing backticks, using a `:literal:`
      role (#3974).
      + Don't backslash-escape word-internal punctuation (#3978).
    * Markdown writer:
      + Don't include variables in metadata blocks.  Previously variables set
      on the command line were included in e.g. YAML metadata, contrary to
      documentation and intentions.
      + Improved escaping with `+smart`.
      + Fixed grid tables embedded in grid tables (#2834).
      + Use span with class 'smallcaps' for SmallCaps, instead of a style
      attribute as before (#1592).
      + Escape initial `%` in a paragraph if the `pandoc_title_blocks`
      extension is enabled (#3454).  Otherwise in a document starting with
      a literal `%` the first line is wrongly interpreted as a title.
      + Fixed false ordered lists in YAML metadata (#3492, #1685).  Now we
      properly escape things that would otherwise start ordered lists,
      such as
    - --
      title: 1. inline
      ...
      + Better handling of tables with empty columns (#3337).  We now
      calculate the number of columns based on the longest row (or the
      length of aligns or widths).
      + Escape unordered list markers at beginning of paragraph (#3497), to
      avoid false interpretation as a list.
      + Escape `|` appropriately.
      + Ensure space before list at top level (#3487).
      + Avoid spurious blanklines at end of document after tables and list,
      for example.
      + Fixed bugs in simple/multiline list output (#3384).
      Previously we got overlong lists with `--wrap=none`.  This is fixed.
      Previously a multiline list could become a simple list (and would
      always become one with `--wrap=none`).
      + Don't emit a simple table if `simple_tables` disabled (#3529).
      + Case-insensitive reference links (David A Roberts, #3616).
      Ensure that we do not generate reference links whose labels differ only
      by case.  Also allow implicit reference links when the link
      text and label are identical up to case.
      + Put space before reference link definitions (Mauro Bieg, #3630).
      + Better escaping for links (David A. Roberts, #3619).  Previously the
      Markdown writer would sometimes create links where there were none
      in the source.  This is now avoided by selectively escaping bracket
      characters when they occur in a place where a link might be created.
      + Added missing `\n` (David A. Roberts, #3647).
      + Fixed duplicated reference links with `--reference-links`
      and `--reference-location=section` (#3674).  Also ensure that there
      are no empty link references `[]`.
      + Avoid inline surround-marking with empty content (#3715).
      E.g. we don't want `<strong></strong>` to become `****`.
      Similarly for emphasis, super/subscript, strikeout.
      + Don't allow soft break in header (#3736).
      + Make sure `plain`, `markdown_github`, etc. work for raw.
      Previously only `markdown` worked.  Note: currently a raw block labeled
      `markdown_github` will be printed for any `markdown` format.
      + Ensure that `+` and `-` are escaped properly so they don't cause
      spurious lists (#3773).  Previously they were only
      if succeeded by a space, not if they were at end of line.
      + Use pipe tables if `raw_html` disabled and `pipe_tables` enabled,
      even if the table has relative width information (#3734).
      + Markdown writer: don't crash on `Str ""`.
      + Make `Span` with null attribute transparent.  That is, we don't use
      brackets or `<span>` tags to mark spans when there are no attributes;
      we simply output the contents.
      + Escape pipe characters when `pipe_tables` enabled (#3887).
      + Better escaping of `<` and `>`.  If `all_symbols_escapable` is set,
      we backslash escape these.  Otherwise we use entities as before.
      + When writing plain, don't use `&nbsp;` to separate list and indented
      code.  There's no need for it in this context, since this isn't to be
      interpreted using Markdown rules.
      + Preserve classes in JS obfuscated links (Timm Albers, #2989).
      HTML links containing classes originally now preserve them when using
      JavaScript email obfuscation.
      + Render `SmallCaps` as a native span when `native_spans` are enabled.
      + Always write attributes with `bracketed_spans` (d-dorazio).
    * Man writer:
      + Fix handling of nested font commands (#3568).  Previously pandoc emitted
      incorrect markup for bold + italic, for example, or bold + code.
      + Avoid error for definition lists with no definitions (#3832).
    * DocBook writer:
      + Fix internal links with `writerIdentifierPrefix opt`
      (#3397, Mauro Bieg).
    * Docx writer:
      + Don't include bookmarks on headers unless non-null id (#3476).
      + Support 9 levels of headers (#1642).
      + Allow 9 list levels (#3519).
      + Don't take `distArchive` from datadir (#3322).  The docx writer takes
      components from the distribution's version of `reference.docx` when it
      can't find them in a user's custom `reference.docx`.  Previously, we
      allowed a `reference.docx` in the data directory (e.g. `~/.pandoc`)
      to be used as the distribution's reference.docx.  This led to a
      bizarre situation where pandoc would produce a good docx using
      `--template ~/.pandoc/ref.docx`, but if `ref.docx` were moved to
      `~/.pandoc/reference.docx`, it would then produce a corrupted docx.
      + Fixed handling of soft hyphen (0173) (#3691).
      + Better handling of keywords (#3719).
      + Cleaner code for handling dir and style attributes for `Div`.
      + Use `Set` for dynamic styles to avoid duplicates.
      + Removed redundant element from data/docx/word/numbering.xml.
      The elements we need are generated when the document is
      compiled; this didn't do anything.
      + Activate `evenAndOddHeaders` from reference docx (#3901,
      Augustín Martín Barbero).
    * ODT/OpenDocument writer:
      + Calculate aspect ratio for percentage-sized images (Mauro Bieg, #3239).
      + Use more widely available bullet characters (#1400).  The old
      characters weren't available in some font sets.  These seem to work
      well on Windows and Linux versions of LibreOffice.
      + Wider labels for lists (#2421).  This avoids overly narrow labels for
      ordered lists with `()` delimiters.  However, arguably it creates
      overly wide labels for bullets.  Also, lists now start flush with
      the margin, rather than indented.
      + Fixed dropped elements in some ordered lists (#2434).
    * FB2 writer:
      + Don't render `RawBlock` as code.
      + Don't fail with an error on interior headers (e.g. in list) (#3750).
      Instead, omit them with an INFO message.
      + Add support for "lang" metadata (Alexander Krotov, #3625).
      + Format `LineBlock` as poem (Alexander Krotov).  Previously writer
      produced one paragraph with `<empty-line/>` elements, which are not
      allowed inside `<p>` according to FB2 schema.
      + Replace `concatMap` with `cMap` (Alexander Krotov).
      + Write FB2 lists without nesting blocks inside `<p>` (Alexander
      Krotov, #4004)
    * HTML writer:
      + Make sure `html4`, `html5` formats work for raw blocks/inlines.
      + Render raw inline environments when `--mathjax` used (#3816).
      We previously did this only with raw blocks, on the assumption
      that math environments would always be raw blocks. This has changed
      since we now parse them as inline environments.
      + Ensure we don't get two style attributes for width and height.
      + Report when not rendering raw inline/block.
      + Issue warning if no title specified and template used (#3473).
      + Info message if `lang` is unspecified (#3486).
      + Removed unused parameter in `dimensionsToAttributeList`.
      + Avoid two class attributes when adding `uri` class (#3716).
      + Fix internal links with `writerIdentifierPrefix opt` (#3397, Mauro
      Bieg).
      + Use revealjs's math plugin for mathjax (#3743).  This is a thin
      wrapper around mathjax that makes math look better on revealjs.
      + Slidy:  use h1 for all slides, even if they were originally
      level 2 headers (#3566).  Otherwise the built-in table of contents
      in Slidy breaks.
    * LaTeX writer:
      + Don't render LaTeX images with data: URIs (#3636).  Note that
      `--extract-media` can be used when the input contains data: URIs.
      + Make highlighted code blocks work in footnotes (Timm Albers).
      + Don't use figure inside table cell (#3836).
      + Use proper code for list enumerators (#3891).  This should fix problems
      with lists that don't use arabic numerals.
      + Always add hypertarget when there's a non-empty identifier (#2719).
      Previously the hypertargets were only added when there was actually
      a link to that identifier.
      + Use `%` after hypertarget before code block.
      + Add `\leavevmode` before hypertarget at start of paragraph (#2704,
      fixes formatting problems in beamer citations).
      + Don't use `lstinline` in \item[..] (#645).  If you do, the contents
      of item disappear or are misplaced.  Use `\texttt` instead.
      + Fix problem with escaping in `lstinline` (#1629).  Previously the
      LaTeX writer created invalid LaTeX when `--listings` was specified and
      a code span occured inside emphasis or another construction.
      + Fix error with line breaks after empty content (#2874).  LaTeX
      requires something before a line break, so we insert a `~` if no
      printable content has yet been emitted.
      + Use BCP47 parser.
      + Fixed detection of otherlangs (#3770).  We weren't recursing into
      inline contexts.
      + Handle language in inline code with `--listings` (#3422).
      + Write euro symbol directly in LaTeX (Andrew Dunning, #3801).
      The textcomp package allows pdfLaTeX to parse `€` directly, making the
      `\euro` command unneeded.
      + Fixed footnotes in table captions (#2378).  Note that if the table has
      a first page header and a continuation page header, the notes will
      appear only on the first occurrence of the header.
      + In `writeBeamer` output, allow hyperlinks to frames (#3220).
      Previously you could link to a header above or below slide level but
      not *to* slide level.  This commit changes that.  Hypertargets are
      inserted inside frame titles; technically the reference is to just
      after the title, but in normal use (where slides are viewed full
      screen in a slide show), this does not matter.
      + Remove `\strut` at beginning of table cells (#3436).  This fixes a
      problem with alignment of lists in table cells.  The `\strut` at the
      end seems to be enough to avoid the too-close spacing that motivated
      addition of the strut  in #1573.
      + Add partial siunitx Support (Marc Schreiber, #3588).
    * ConTeXt writer:
      + Refactored to use BCP47 module.
      + Remove unnecessary `$` (Alexander Krotov, #3482).
      + Use header identifiers for chapters (#3968).
    * EPUB writer:
      + `title_page.xhtml` is now put in `text/`.
      + Don't strip formatting in TOC (#1611).
    * Textile reader:
      + Fix bug for certain links in table cells (#3667).
      + Allow 'pre' code in list item (#3916).
    * HTML reader:
      + Added warnings for ignored material (#3392).
      + Better sanity checks to avoid parsing unintended things as
      raw HTML in the Markdown reader (#3257).
      + Revise treatment of `li` with `id` attribute (#3596).  Previously we
      always added an empty div before the list item, but this created
      problems with spacing in tight lists.  Now we do this: If the list
      item contents begin with a `Plain` block, we modify the `Plain`
      block by adding a `Span` around its contents.  Otherwise, we add a
      `Div` around the contents of the list item (instead of adding an
      empty `Div` to the beginning, as before).
      + Add `details` tag to list of block tags (#3694).
      + Removed `button` from block tag list (#3717).  It is already in the
      `eitherBlockOrInlineTag` list, and should be both places.
      + Use `Set`s instead of lists for block tag lookup.
      + Rewrote to use `Text` throughout.  Effect on memory usage is modest
      (< 10%).
      + Use the lang value of `<html>` to set the lang meta value (bucklereed,
      [#3765]).
      + Ensure that paragraphs are closed properly when the parent block
      element closes, even without `</p>` (#3794).
      + Parse `<figure>` and `<figcaption>` (Mauro Bieg, #3813).
      + Parse `<main>` like `<div role=main>` (bucklereed, #3791).
      `<main>` closes `<p>` and behaves like a block element generally
      + Support column alignments (#1881).  These can be set either
      with a `width` attribute or with `text-width` in a `style` attribute.
      + Modified state type to be an instance of `HasLogMessages`, so
      `registerHeader` can issue warnings.
      + `</td>` or `</th>` should close any open block tag (#3991).
      + `<td>` should close an open `<th>` or `<td>`.
      + `htmlTag` improvements (#3989).  We previously failed on cases
      where an attribute contained a `>` character. This patch fixes the
      bug, which especially affects raw HTML in Markdown.
    * Txt2Tags reader:
      + Newline is not indentation (Alexander Krotov).
    * MediaWiki reader:
      + Allow extra hyphens after `|-` in tables (#2649).
      + Allow blank line after table start (#2649).
      + Fixed more table issues (#2649).
      + Ensure that list starts begin at left margin (#2606).  Including when
      they're in tables or other list items.
      + Make smart double quotes depend on `smart` extension (#3585).
      + Don't do curly quotes inside `<tt>` contexts (#3585).  Even if `+smart`.
      + Modified state type to be an instance of `HasLogMessages`, so
      `registerHeader` can issue warnings.
    * TWiki reader (Alexander Krotov):
      + Remove unnecessary `$` (#3597).
      + Simplify `linkText` (#3605).
    * EPUB reader:
      + Minor refactoring, avoiding explicit MediaBag handling.
      This all works behind the scenes in CommonState plumbing.
    * Docx reader:
      + Don't drop smartTag contents (#2242).
      + Handle local namespace declarations (#3365).  Previously we didn't
      recognize math, for example, when the xmlns declaration occured on
      the element and not the root.
      + More efficient trimSps (#1530).  Replacing `trimLineBreaks`.  This
      does the work of `normalizeSpaces` as well, so we avoid the need for
      that function here.
      + Avoid 0-level headers (Jesse Rosenthal, #3830).  We used to parse
      paragraphs styled with "HeadingN" as "nth-level header." But if a
      document has a custom style named "Heading0", this will produce a
      0-level header, which shouldn't exist. We only parse this style
      if N>0. Otherwise we treat it as a normal style name, and
      follow its dependencies, if any.
      + Add tests for avoiding zero-level header (Jesse Rosenthal).
    * ODT reader:
      + Replaced `collectRights` with Rights from `Data.Either`.
      + Remove dead code (Albert Krewinkel).
    * Org reader (Albert Krewinkel, unless noted).
      + Don't allow tables inside list items (John MacFarlane, #3499).
      + Disallow tables on list marker lines (#3499).
      + Convert markup at beginning of footnotes (John MacFarlane, #3576).
      + Allow emphasized text to be followed by `[` (#3577).
      + Handle line numbering switch for src blocks.
      The line-numbering switch that can be given to source blocks (`-n` with
      an start number as an optional parameter) is parsed and translated to a
      class/key-value combination used by highlighting and other readers and
      writers.
      + Stop adding rundoc prefix to src params.  Source block parameter names
      are no longer prefixed with `rundoc`. This was intended to simplify
      working with the rundoc project, a babel runner. However, the rundoc
      project is unmaintained, and adding those markers is not the reader's
      job anyway.  The original language that is specified for a source
      element is now retained as the `data-org-language` attribute and only
      added if it differs from the translated language.
      + Allow multi-word arguments to src block params (#3477).  The reader now
      correctly parses src block parameter list even if parameter arguments
      contain multiple words.
      + Avoid creating `nullMeta` by applying `setMeta` directly
      (Alexander Krotov).
      + Replace `sequence . map` with `mapM`.
      + Fix smart parsing behavior.  Parsing of smart quotes and special
      characters can either be enabled via the `smart` language extension or
      the `'` and `-` export options. Smart parsing is active if either the
      extension or export option is enabled.  Only smart parsing of special
      characters (like ellipses and en and em dashes) is enabled by default,
      while smart quotes are disabled.  Previously, all smart parsing was
      disabled unless the language extension was enabled.
      + Subject full doc tree to headline transformations (Albert Krewinkel,
      [#3695]).  Emacs parses org documents into a tree structure, which is
      then post-processed during exporting. The reader is changed to do the
      same, turning the document into a single tree of headlines starting
      at level 0.
      + Fix cite parsing behaviour (Herwig Stuetz).  Until now, `org-ref`
      cite keys included special characters also at the end. This caused
      problems when citations occur right before colons or at the end of
      a sentence.  With this change, all non alphanumeric characters at
      the end of a cite key are ignored.  This also adds `,` to the list
      of special characters that are legal in cite keys to better mirror
      the behaviour of org-export.
      + Fix module names in haddock comments.  Copy-pasting had lead to
      haddock module descriptions containing the wrong module names.
      + Recognize babel result blocks with attributes (#3706).  Babel
      result blocks can have block attributes like captions and names.
      Result blocks with attributes were not recognized and were parsed
      as normal blocks without attributes.
      + Include tags in headlines.  The Emacs default is to include tags in the
      headline when exporting.  Instead of just empty spans, which contain the
      tag name as attribute, tags are rendered as small caps and wrapped in
      those spans.  Non-breaking spaces serve as separators for multiple tags.
      + Respect export option for tags (#3713).  Tags are appended to
      headlines by default, but will be omitted when the `tags` export option
      is set to nil.
      + Use `tag-name` attribute instead of `data-tag-name`.
      + Use `org-language` attribute rather than `data-org-language`.
      + Modified state type to be an instance of `HasLogMessages`, so
      `registerHeader` can issue warnings.
      + End footnotes after two blank lines.  Footnotes can not only be
      terminated by the start of a new footnote or a header, but also by two
      consecutive blank lines.
      + Update emphasis border chars (#3933).  The org reader was updated to
      match current org-mode behavior: the set of characters which are
      acceptable to occur as the first or last character in an org emphasis
      have been changed and now allows all non-whitespace chars at the
      inner border of emphasized text (see `org-emphasis-regexp-components`).
    * RST reader:
      + Fixed small bug in list parsing (#3432).  Previously the parser didn't
      handle properly this case:
    * - a
    - b
    * - c
    - d
      + Handle multiline cells in simple tables (#1166).
      + Parse list table directive (Keiichiro Shikano, #3432).
      + Make use of `anyLineNewline` (Alexander Krotov, #3686).
      + Use `anyLineNewline` in `rawListItem` (Alexander Krotov, #3702).
      + Reorganize block parsers for ~20% faster parsing.
      + Fixed `..include::` directive (#3880).
      + Handle blank lines correctly in line blocks (Alexander Krotov, #3881).
      Previously pandoc would sometimes combine two line blocks separated
      by blanks, and ignore trailing blank lines within the line block.
      + Fix indirect hyperlink targets (#512).
    * Markdown reader:
      + Allow attributes in reference links to start on next line (#3674).
      + Parse YAML metadata in a context that sees footnotes defined in
      the body of the document (#1279).
      + When splitting pipe table cells, skip tex math (#3481).
      You might have a `|` character inside math.  (Or for that matter
      something that the parser might mistake for raw HTML.)
      + Treat span with class `smallcaps` as SmallCaps.
      This allows users to specify small caps in Markdown this way:
      `[my text]{.smallcaps}` (#1592).
      + Fixed internal header links (#2397).
      This patch also adds `shortcut_reference_links` to the list
      of mmd extensions.
      + Treat certain environments as inline
      when they occur without space surrounding them (#3309, #2171).
      E.g. equation, math.  This avoids incorrect vertical space
      around equations.
      + Optimized `nonindentSpaces`.  Makes the benchmark go from 40 to 36 ms.
      + Allow latex macro definitions indented 1-3 spaces.
      Previously they only worked if nonindented.
      + Improved parsing of indented raw HTML blocks (#1841).
      Previously we inadvertently interpreted indented HTML as
      code blocks.  This was a regression.  We now seek to determine the
      indentation level of the contents of an HTML block, and (optionally)
      skip that much indentation.  As a side effect, indentation may be
      stripped off of raw HTML blocks, if `markdown_in_html_blocks` is
      used. This is better than having things interpreted as indented
      code blocks.
      + Fixed smart quotes after emphasis (#2228).  E.g. in `*foo*'s 'foo'`.
      + Warn for notes defined but not used (#1718).
      + Use `anyLineNewline` (Alexander Krotov).
      + Interpret YAML metadata as Inlines when possible (#3755).  If
      the metadata field is all on one line, we try to interpret it as
      Inlines, and only try parsing as Blocks if that fails.  If it
      extends over one line (including possibly the `|` or `>` character
      signaling an indented block), then we parse as Blocks.  This was
      motivated by some German users finding that `date: '22. Juin 2017'`
      got parsed as an ordered list.
      + Fixed spurious parsing as citation as reference def (#3840).
      We now disallow reference keys starting with `@` if the
      `citations` extension is enabled.
      + Parse `-@roe` as suppress-author citation (pandoc-citeproc#237).
      Previously only `[-@roe]` (with brackets) was recognized as
      suppress-author, and `-@roe` was treated the same as `@roe`.
      + Fixed parsing of fenced code after list when there is no intervening
      blank line (#3733).
      + Allow raw latex commands starting with `\start` (#3558).  Previously
      these weren't allowed because they were interpreted as starting
      ConTeXt environments, even without a corresponding `\stop`...
      + Added `inlines`, `inlines1`.
      + Require nonempty alt text for `implicit_figures` (#2844).
      A figure with an empty caption doesn't make sense.
      + Removed texmath macro material; now all this is handled
      in the LaTeX reader functions.
      + Fixed bug with indented code following raw LaTeX (#3947).
    * LaTeX reader:
      + Rewrote LaTeX reader with proper tokenization (#1390,
      [#2118], #3236, #3779, #934, #982).  This rewrite is primarily
      motivated by the need to get macros working properly.  A side benefit
      is that the reader is significantly faster.  We now tokenize the
      input text, then parse the token stream.  Macros modify the token
      stream, so they should now be effective in any context, including
      math. Thus, we no longer need the clunky macro processing
      capacities of texmath.
      + Parse `\,` to `\8198` (six-per-em space) (Henri Werth).
      + Allow `\newcommand\foo{blah}` without braces.
      + Support `\lstinputlisting` (#2116).
      + Issue warnings when skipping unknown latex commands (#3392).
      + Include contents of `\parbox`.
      + Allow `\hspace` and `\vspace` to count as raw block or inline.
      Previously we would refuse to parse anything as raw inline if
      it was in the `blockCommands` list.  Now we allow exceptions
      if they're listed under ignoreInlines in inlineCommands.
      This should make it easier e.g. to include an `\hspace`
      between two side-by-side raw LaTeX tables.
      + Don't drop contents of `\hypertarget`.
      + Handle spaces before `\cite` arguments.
      + Allow newpage, clearpage, pagebreak in inline contexts as well as
      block contexts (#3494).
      + Treat `{{xxx}}` the same as `{xxx}` (#2115).
      + Use `pMacroDefinition` in macro (for more direct parsing).
      Note that this means that `macro` will now parse one
      macro at a time, rather than parsing a whole group together.
      + Fixed failures on \ref{}, \label{} with `+raw_tex`.  Now these
      commands are parsed as raw if `+raw_tex`; otherwise, their argument
      is parsed as a bracketed string.
      + Don't crash on empty `enumerate` environment (#3707).
      + Handle escaped `&` inside table cell (#3708).
      + Handle block structure inside table cells (#3709).  `minipage` is no
      longer required.
      + Handle some width specifiers on table columns (#3709).  Currently
      we only handle the form `0.9\linewidth`.  Anything else would have
      to be converted to a percentage, using some kind arbitrary assumptions
      about line widths.
      + Make sure `\write18` is parsed as raw LaTeX.  The change is in the
      LaTeX reader's treatment of raw commands, but it also affects the
      Markdown reader.
      + Fixed regression with starred environment names (#3803).
      + Handle optional args in raw `\titleformat` (#3804).
      + Improved heuristic for raw block/inline.  An unknown command at the
      beginning of the line that could be either block or inline is
      treated as block if we have a sequence of block commands followed by
      a newline or a `\startXXX` command (which might start a raw ConTeXt
      environment).
      + Don't remove macro definitions from the output, even if
      `Ext_latex_macros` is set, so that macros will be applied.
      Since they're only applied to math in Markdown, removing the macros
      can have bad effects.  Even for math macros, keeping them should be
      harmless.
      + Removed `macro`.  It is no longer necessary, since the
      `rawLaTeXBlock` parser will parse macro definitions.  This also avoids
      the need for a separate `latexMacro` parser in the Markdown reader.
      + Use `label` instead of `data-label` for label in caption (#3639).
      + Fixed space after \figurename etc.
      + Resolve references to section numbers.
      + Fix `\let\a=0` case, with single character token.
      + Allow `@` as a letter in control sequences.  `@` is commonly used
      in macros using `\makeatletter`.  Ideally we'd make the tokenizer
      sensitive to `\makeatletter` and `\makeatother`, but until then this
      seems a good change.
      + Track header numbers and correlate with labels.
      + Allow `]` inside group in option brackets (#3857).
      + lstinline with braces can be used (verb cannot be used with braces)
      (Marc Schreiber, #3535).
      + Fix keyval funtion: pandoc did not parse options in braces correctly
      (Marc Schreiber, #3642).
      + When parsing raw LaTeX commands, include trailing space (#1773).
      Otherwise things like `\noindent foo` break and turn into
      `\noindentfoo`.  Affects `-f latex+raw_tex` and `-f markdown` (and other
      formats that allow `raw_tex`).
      + Don't treat "..." as Quoted (#3958).  This caused quotes to be omitted in
      `\texttt` contexts.
      + Add tests for existing `\includegraphics` behaviour (Ben Firshman).
      + Allow space before `=` in bracketd options (Ben Firshman).
      + Be more forgiving in parsing command options.  This was needed, for
      example, to make some minted options work.
      + Strip off quotes in `\include` filenames.
    * Added `Text.Pandoc.CSV`, simple (unexported) CSV parser.
    * `Text.Pandoc.PDF`:
      + Got `--resource-path` working with PDF output (#852).
      + Fetch images when generating PDF via context (#3380).
      To do this, we create the temp directory as a subdirectory
      of the working directory. Since context mk IV by default looks
      for images in the parent directory, this works.
      + Use `report` instead of `warn`, make it sensitive to verbosity settings.
      + Use `fillMediaBag` and `extractMedia` to extract media to temp dir.
      This reduces code duplication.
      + `html2pdf`: use stdin instead of intermediate HTML file
      + Removed useless `TEXINPUTS` stuff for `context2pdf`.  mkiv context
      doesn't use `TEXINPUTS`.
    * `Text.Pandoc.Pretty`:
      + Simplified definition of `realLength`.
      + Don't error for blocks of size < 1.  Instead, resize to 1 (see #1785).
    * `Text.Pandoc.MIME`:
      + Use `application/javascript` (not `application/x-javascript`).
      + Added `emf` to mimeTypes with type `application/x-msmetafile` (#1713).
    * `Text.Pandoc.ImageSize`:
      + Improve SVG image size code (Marc Schreiber, #3580).
      + Make `imageSize` recognize basic SVG dimensions (Mauro Bieg, #3462).
    * Use `Control.Monad.State.Strict` throughout.  This gives 20-30% speedup
      and reduction of memory usage in most of the writers.
    * Use `foldrWithKey` instead of deprecated `foldWithKey`.
    * `Text.Pandoc.SelfContained`:
      + Fixed problem with embedded fonts (#3629).
      + Refactored getData from `getDataURI` in `SelfContained`.
      + Don't use data URIs for script or style (#3423).  Instead, just use
      script or style tags with the content inside.  The old method with
      data URIs prevents certain optimizations outside pandoc.  Exception:
      data URIs are still used when a script contains `</script>` or a
      style contains `</`.
      + SelfContained: Handle URL inside material retrieved from a URL
      (#3629).  This can happen e.g. with an @import of a google web font.
      (What is imported is some CSS which contains an url reference
      to the font itself.) Also, allow unescaped pipe (|) in URL.
      + Load resources from `data-src` (needed for lazy loading in
      reveal.js slide shows).
      + Handle `data-background-image` attribute on section (#3979).
    * `Text.Pandoc.Parsing`:
      + Added `indentWith` (Alexander Krotov, #3687).
      + Added `stateCitations` to `ParserState`.
      + Removed `stateChapters` from `ParserState`.
      + In `ParserState`, make `stateNotes'` a Map, add `stateNoteRefs`.
      + Added `gobbleSpaces` and `gobbleAtMostSpaces`.
      + Adjusted type of `insertIncludedFile` so it can be used with token
      parser.
      + Replace old texmath macro stuff from Parsing.  Use Macro from
      Text.Pandoc.Readers.LaTeX.Types instead.
      + Export `insertIncludedFile`.
      + Added `HasLogMessages`, `logMessage`, `reportLogMessages` (#3447).
      + Replace partial with total function (Albert Krewinkel).
      + Introduce `HasIncludeFiles` type class (Albert Krewinkel).  The
      `insertIncludeFile` function is generalized to work with all parser
      states which are instances of that class.
      + Add `insertIncludedFilesF` which returns F blocks (Albert Krewinkel).
      The `insertIncludeFiles` function was generalized and renamed
      to `insertIncludedFiles'`; the specialized versions are based on that.
      + `many1Till`: Check for the end condition before parsing (Herwig
      Stuetz).  By not checking for the end condition before the first
      parse, the parser was applied too often, consuming too much of the
      input. This only affects `many1Till p end` where `p` matches on a
      prefix of `end`.
      + Provide `parseFromString` (#3690).  This is a verison of
      `parseFromString` specialied to ParserState, which resets
      `stateLastStrPos` at the end.  This is almost always what we want.
      This fixes a bug where `_hi_` wasn't treated as emphasis in the
      following, because pandoc got confused about the position of the
      last word: `- [o] _hi_`.
      + Added `takeP`, `takeWhileP` for efficient parsing of `[Char]`.
      + Fix `blanklines` documentation (Alexander Krotov, #3843).
      + Give less misleading line information with `parseWithString`.
      Previously positions would be reported past the end of the chunk.
      We now reset the source position within the chunk and report
      positions "in chunk."
      + Add `anyLineNewline` (Alexander Krotov).
      + Provide shared F monad functions for Markdown and Org readers
      (Albert Krewinkel).  The `F` monads used for delayed evaluation
      of certain values in the Markdown and Org readers are based on a
      shared data type capturing the common pattern of both `F` types.
      + Add `returnF` (Alexander Krotov).
      + Avoid parsing `Notes:**` as a bare URI (#3570).  This avoids parsing
      bare URIs that start with a scheme + colon + `*`, `_`, or `]`.
      + Added `readerAbbreviations` to `ParserState`.  Markdown reader
      now consults this to determine what is an abbreviation.
      + Combine grid table parsers (Albert Krewinkel, #3638).  The grid table
      parsers for markdown and rst was combined into one single
      parser `gridTable`, slightly changing parsing behavior of both
      parsers: (1) The markdown parser now compactifies block content
      cell-wise: pure text blocks in cells are now treated as paragraphs
      only if the cell contains multiple paragraphs, and as plain blocks
      otherwise. Before, this was true only for single-column tables. (2)
      The rst parser now accepts newlines and multiple blocks in header
      cells.
      + Generalize tableWith, gridTableWith (Albert Krewinkel).
      The parsing functions `tableWith` and `gridTableWith` are generalized
      to work with more parsers. The parser state only has to be an
      instance of the `HasOptions` class instead of requiring a concrete
      type. Block parsers are required to return blocks wrapped into a
      monad, as this makes it possible to use parsers returning results
      wrapped in `Future`s.
    * `Text.Pandoc.Shared`:
      + Simplify `toRomanNumeral` using guards (Alexander Krotov, #3445)
      + `stringify`: handle Quoted better (#3958).  Previously we were losing
      the quotation marks in Quoted elements.
    * `Text.Pandoc.Writers.Shared`:
      + Export `metaToJSON'`, `addVariablesToJSON` (#3439).
      This allows us to add the variables AFTER using the metadata
      to generate a YAML header (in the Markdown writer).
      + Added `unsmartify` (previously in RST writer).
      Undo literal double curly quotes.  Previously we left these.
      + Generalize type of `metaToJSON` so it can take a Text.  Previously a
      String was needed as argument; now any ToJSON instance will do.
      + Added `gridTable` (previously in Markdown writer).
      + `gridTable`: Refactored to use widths in chars.
      + `gridTable`:  remove unnecessary extra space in cells.
      + Fixed `addVariablesToJSON`.  It was previously not allowing multiple
      values to become lists.
      + Pipe tables: impose minimum cell size (see #3526).
    [default template changes]
    * HTML templates (including EPUB and HTML slide show templates):
      + Make default.html5 polyglot markup conformant (John Luke Bentley,
      [#3473]).  Polyglot markup is HTML5 that is also valid XHTML. See
      <https://www.w3.org/TR/html-polyglot>.  With this change, pandoc's
      html5 writer creates HTML that is both valid HTML5 and valid XHTML.
      + Regularized CSS in html/epub/html slide templates (#3485).
      All templates now include `code{white-space: pre-wrap}`
      and CSS for `q` if `--html-q-tags` is used.  Previously some templates
      had `pre` and others `pre-wrap`; the `q` styles were only sometimes
      included.
      + CSS for `.smallcaps`, (Mauro Bieg, #1592)
      + `default.revealjs`: make `history` default to true.
      + `default.revealjs`: use lazy loading (#2283).
      + `default.revealjs`: add `mathjax` variable and some conditional code
      to use the MathJaX plugin.
      + `default.slidy` uses `https` instead of `http` (ickc, #3848).
      + `default.dzslides`: Load Google Font using HTTPS by default
      (Yoan Blanc).
    * DocBook5 template: Use `lang` and `subtitle` variables (Jens Getreu,
      [#3855]).
    * LaTeX/Beamer template:
      + Combine LaTeX/Beamer templates (Andrew Dunning, #3878).
      `default.beamer` has been removed; beamer now uses the
      `default.latex` template.  Beamer-specific parts are conditional
      on the `beamer` variable set by the writer. Note that
      `pandoc -D beamer` will return this (combined) template.
      + Use `xcolor` for `colorlinks` option (Andrew Dunning, #3877).
      Beamer loads `xcolor` rather than `color`, and thus the
      `dvipsnames` option doesn't take effect. This also provides a wider
      range of colour selections with the `svgnames` option.
      + Use starred versions of `xcolor` names (Andrew Dunning).
      Prevents changes to documents defined using the `dvipsnames` list (e.g.
      `Blue` gives a different result with svgnames enabled).
      + Load `polyglossia` after header-includes (#3898).  It needs to be
      loaded as late as possible.
      + Use `unicode-math` (Vaclav Haisman).  Use `mathspec` with only
      XeLaTeX on request.
      + Don't load `fontspec` before `unicode-math` (over there).
      The `unicode-math` package loads `fontspec` so explict loading of
      `fontspec` before `unicode-math` is not necessary.
      + Use `unicode-math` by default in default.latex template.  mathspec will
      be used in xelatex if the `mathspec` variable is set; otherwise
      unicode-math will be used (Václav Haisman).
      + Use `dvipsnames` options when `colorlinks` specified (otherwise
      we get an error for `maroon`) (Thomas Hodgson).
      + Added beamer `titlegraphic` and `logo` variables (Thomas Hodgson).
      + Fix typo in fix for notes in tables (#2378, zeeMonkeez).
      + Fix `hyperref` options clash (Andrew Dunning, #3847) Avoids an options
      clash when loading a package (e.g. `tufte-latex`) that uses
      `hyperref` settings different from those in the template.
      + Add `natbiboptions` variable (#3768).
      + Fix links inside captions in LaTeX output with links-as-notes
      (Václav Haisman, #3651).  Declare our redefined `\href` robust.
      + Load `parskip` before `hyperref` (Václav Haisman, #3654).
      + Allow setting Japanese fonts when using LuaLaTeX (Václav Haisman,
      [#3873]).  by using the `luatexja-fontspec` and `luatexja-preset`
      packages. Use existing `CJKmainfont` and `CJKoptions` template
      variables. Add `luatexjafontspecoptions` for `luatexja-fontspec`
      and `luatexjapresetoptions` for `luatexja-preset`.
      + Added `aspectratio` variable to beamer template (Václav Haisman,
      [#3723]).
      + Modified template.latex to fix XeLaTex being used with tables
      (lwolfsonkin, #3661).  Reordered `lang` variable handling to
      immediately before `bidi`.
    * ConTeXt template: Improved font handling: `simplefonts` is now
      obsolete in ConTeXt (Pablo Rodríguez).
    [documentation improvements]
    * MANUAL.txt:
      + Add URL for Prince HTML > PDF engine (Ian, #3919).
      + Document that content above slide-level will be omitted in
      slide shows.  See #3460, #2265.
      + Explain `--webtex` SVG url (Mauro Bieg, #3471)
      + Small clarification in YAML metadata section.
      + Document that html4 is technically XHTML 1.0 transitional.
      + Remove refs to highlighting-kate (#3672).
      + Document ibooks specific epub metadata.
      + Clarify that mathml is used for ODT math.
      + Mention limitations of Literate Haskell Support (#3410,
      Joachim Breitner).
      + Add documentation of limitations of grid tables (Stephen
      McDowell, #3864).
      + Clarify that meta-json contains transformed values (Jakob Voß,
      [#3491]) Make clear that template variable `meta-json` does not
      contain plain text values or JSON output format but field values
      transformed to the selected output format.
    * COPYRIGHT:
      + Clarify that templates are dual-licensed.
      + Clarify that pandoc-types is BSD3 licensed.
      + List new files not written by jgm (Albert Krewinkel).
      + Update dates in copyright notices (Albert Krewinkel).  This follows
      the suggestions given by the FSF for GPL licensed software.
      <https://www.gnu.org/prep/maintain/html_node/Copyright-Notices.html>
    * INSTALL.md:
      + Improved instructions for tests with patterns.
      + Put RPM-based distros on separate point (Mauro Bieg, #3449)
    * CONTRIBUTING.md:
      + Fixed typos (Wandmalfarbe, #3479).
      + Add "ask on pandoc-discuss" (Mauro Bieg).
    * Add lua filter documentation in `doc/lua-filters.md`.  Note that the
      end of this document is autogenerated from `data/pandoc.lua`
      using `make doc/lua-filters.md`, which uses `tools/ldoc.ltp`
      (Albert Krewinkel).
    * Add `doc/filters.md`. This is the old scripting tutorial from
      the website.
    * Add `doc/using-the-pandoc-api.md` (#3289).  This gives an introduction
      to using pandoc as a Haskell library.
    [build infrastructure improvements]
    * Removed `data/templates` submodule.  Templates are now a subtree
      in `data/templates`.  This removes the need to do `git submodule
      update`.
    * Renamed `tests` -> `test`.
    * Remove `https` flag.  Always build with HTTPS support.
    * Use `file-embed` instead of `hsb2hs` to embed data files when
      `embed_data_files` flag is set.  `file-embed` gives us better dependency
      tracking:  if a data file changes, ghc/stack/cabal know to recompile
      the Data module.  This also removes `hsb2hs` as a build dependency.
    * Add `custom-setup` stanza to pandoc, lowercase field names.
    * Add `static` Cabal flag.
    * Name change OSX -> MacOS.  Add a -MacOS suffix to mac package rather
      than -OSX.  Changed local names from osx to macos.
    * make_macos_package.sh - Use strip to reduce executable size.
    * Revised binary linux package.  Now a completely static executable
      is created, using Docker and alpine.  We create both a deb and a
      tarball.  The old `deb` directory has been replaced with a `linux`
      directory.  Running `make` in the `linux` directory should
      perform the build, putting the binary packages in `artifacts/`.
    * `linux/control.in`: add `Replaces:`, so existing pandoc-citeproc and
      pandoc-data packages will be uninstalled; this package provides
      both (#3822).  Add latex packages as 'suggested', update
      description.
    * Remove cpphs build requirement -- it is no longer needed.
    * Replaced `{deb,macos,windows}/stack.yaml` with `stack.pkg.yaml`.
    * Name change OSX -> macOS (ickc, #3869).
    * Fix casing of Linux, UNIX, and Windows (ickc).
    * `.travis.yml`:  create a source dist and do cabal build and test there.
      That way we catch errors due to files missing from the data
      section of pandoc.cabal.
    * Makefile:
      + Split `make haddock` from `make full`.
      + Add BRANCH variable for winpkg.
      + Add `lint` target.
      + Improve `make full`. Disable optimizations.
      Build everything, inc. trypandoc and benchmarks.  Use parallel build.
      + Allow `make test` to take `TESTARGS`.
    * Added new command tests (`Tests.Command`), using small text files
      in `test/command/`.  Any files added in this directory will be treated
      as shell tests (see smart.md for an example).  This makes it very easy
      to add regression tests etc.
    * Test fixes so we can find data files.  In old tests & command tests,
      we now set the environment variable `pandoc_datadir`.  In lua tests,
      we set the datadir explicitly.
    * Refactored `compareOutput` in docx writer test.
    * Consolidated some common functions in `Tests.Helper`.
    * Small change to unbalanced bracket test to speed up test suite.
    * Speed up Native writer quickcheck tests.
    * Use tasty for tests rather than test-framework.
    * Add simple Emacs mode to help with Pandoc templates editing.
      (Václav Haisman, #3889). `tools/pandoc-template-mode.el`
    * Use skylighting library instead of highlighting-kate for syntax
      highlighting. Skylighting is faster and more accurate (#3363).
      Later we'll be able to add features like warning messages, dynamic
      loading of xml syntax definitions, and dynamic loading of themes.
    * Added a new highlight style, `breezeDark`.
    * Text.Pandoc.Highlighting: Update list of `listings` languages (#3374).
      This allows more languages to be used when using the `--listings`
      option.
    * OpenDocument writer:
      + Small refactoring.  Removed separate 'parent' parameter in paraStyle.
      + Don't profilerate text styles unnecessarily (#3371).
      This change makes the writer create only as many temporary
      text styles as are absolutely necessary. It also consolidates
      adjacent nodes with the same style.
    * Org reader (Albert Krewinkel):
      + Allow short hand for single-line raw blocks (Albert Krewinkel,
      [#3366]).  Single-line raw blocks can be given via `#+FORMAT: raw line`,
      where `FORMAT` must be one of `latex`, `beamer`, `html`, or `texinfo`.
      + Accept org-ref citations followed by commas (Albert Krewinkel).
      Bugfix for an issue which, whenever the citation was immediately
      followed by a comma, prevented correct parsing of org-ref citations.
      + Ensure emphasis markup can be nested.  Nested emphasis markup (e.g.
      `/*strong and emphasized*/`) was interpreted incorrectly in that the
      inner markup was not recognized.
      + Remove pipe char irking the haddock coverage tool (Albert Krewinkel).
    * Docx reader: Empty header should be list of lists (Jesse Rosenthal).
      In the past, the docx reader wrote an empty header as an empty list. It
      should have the same width as a row (and be filled with empty cells).
    * MediaWiki reader:
      + Improved handling of display math (#3362).  Sometimes display math is
      indented with more than one colon.  Previously we handled these cases
      badly, generating definition lists and missing the math.
      + Fix quotation mark parsing (#3336, tgkokk).  Change MediaWiki reader's
      behavior when the smart option is parsed to match other readers'
      behavior.
    * Markdown reader:
      + Fixed `-f markdown_github-hard_line_breaks+escaped_line_breaks`
      (#3341).  Previously this did not properly enable escaped line breaks.
      + Disallow space between inline code and attributes (#3326, #3323,
      Mauro Bieg).
    * DocBook5 writer: make id attribute xml:id, fixes #3329 (#3330, Mauro Bieg).
    * Added some test cases for ODT reader (#3306, #3308, Hubert Plociniczak).
    * LaTeX writer: allow tables with empty cells to count as "plain."
      This addresses a problem of too-wide tables when empty cells
      are used.  Thanks to Joost Kremers for reporting the issue.
    * Org writer: prefix footnote numbers with `fn:` (Albert Krewinkel).
      Unprefixed numbers where used by older org-mode versions, but are no
      longer supported.
    * HTML writer: don't process pars with empty RawInline, (#1040, #3327,
      Mauro Bieg).
    * Markdown writer: Fix display math with `--webtex` (#3298).
    * Fix sample.lua so it properly handles raw blocks/inlines (#3358,
      bumper314).
    * Templates:
      + default.latex: Moved geometry after hyperref (Václav Haisman).
      Otherwise PDF sizes can be wrong in some circumstances.
      + Copied a few changes from default.latex to default.beamer
      (Wandmalfarbe).
      + default.latex, default.beamer: Changed position of `\VerbatimNotes`
      and `fancyvrb`.  This fixes hyperlinks on footnotes in documents
      that contain verbatim in notes (#3361).  (Note: the beamer template
      was updated to match the LaTeX template, but at this point verbatim
      in notes seems not to work in beamer.)
      + default.latex: Allow passing `microtypeoptions` to microtype
      (Václav Haisman).
      + default.latex: Add hyphen option to url package.
      + default.docbook5: Fix namespace declarations (Mauro Bieg).
    * Moved `make_osx_package.sh` to `osx/` directory.
    * Travis continuous integration:
      + Fix false positives with dist build.
      + Speed improvements (Kolen Cheung, #3304, #3357).
    * MANUAL.txt:
      + Clarify that blank space is needed around footnotes (#3352).
      + Fixed typo (#3351, Alexey Rogechev).
      + Note that `--wrap=auto` does not work in HTML output.
      + Default `--columns` width is 72, not 80.
      + Fixed broken links (#3316, Kolen Cheung).
      + Document usage of `@*` in nocite section (#3333, John Muccigrosso).
    * INSTALL.md:
      + Indent code so it's properly formatted (#3335, Bheesham Persaud).
      + Added instructions for extracting binary from OSX, Windows packages.
    * CONTRIBUTING.md: Describe labels currently used in issue tracker
      (Albert Krewinkel).  The labels have changed over time, the list of
      labels is updated to reflect the current set of labels used in the
      issue tracker.
    * Rearrange and extend badges in README (Albert Krewinkel, #3354)
    * Bumped version bounds for dependencies.

    * New output format: `docbook5`
    * `Text.Pandoc.Options`: Add `writerDocBook5` to `WriterOptions`
    * Org writer:
    + Add :PROPERTIES: drawer support
      This allows header attributes to be added to org documents in the form
      of `:PROPERTIES:` drawers.  All available attributes are stored as
      key/value pairs.  This reflects the way the org reader handles
      `:PROPERTIES:` blocks.
    + Add drawer capability. For the implementation of the
      Drawer element in the Org Writer, we make use of a generic Block
      container with attributes.  The presence of a `drawer` class defines
      that the `Div` constructor is a drawer. The first class defines the
      drawer name to use.  The key-value list in the attributes defines
      the keys to add inside the Drawer.  Lastly, the list of Block elements
      contains miscellaneous blocks elements to add inside of the Drawer.
    + Use `CUSTOM_ID` in properties.  The `ID` property is
      reserved for internal use by Org-mode and should not be used.
      The `CUSTOM_ID` property is to be used instead, it is converted to the
      `ID` property for certain export format.
    * LaTeX writer:
    + Ignore `--incremental` unless output format is beamer.
    + Fix polyglossia to babel env mapping.
      Allow for optional argument in square brackets.
    + Recognize `la-x-classic` as Classical Latin.
      This allows one to access the hyphenation patterns in CTAN's
      hyph-utf8.
    + Add missing languages from hyph-utf8.
    + Improve use of `\strut` with `\minipage` inside tables
      .  This improves spacing in multiline
      tables.
    + Use `{}` around options containing special chars.
    + Avoid lazy `foldl`.
    + Don't escape underscore in labels.  Previously they were
      escaped as `ux5f`.
    + brazilian -> brazil for polyglossia.
    * HTML writer: Ensure mathjax link is added when math appears in footnote
    . Previously if a document only had math in a footnote, the
    MathJax link would not be added.
    * EPUB writer: set `navpage` variable on nav page.
    This allows templates to treat it differently.
    * DocBook writer:
    + Use docbook5 if `writerDocbook5` is set.
    + Properly handle `ulink`/`link`.
    * EPUB reader:
    + Unescape URIs in spine.
    + EPUB reader:  normalise link id.
    * Docx Reader:
    + Parse `moveTo` and `moveFrom`.
      `moveTo` and `moveFrom` are track-changes tags that are used when a
      block of text is moved in the document. We now recognize these tags and
      treat them the same as `insert` and `delete`, respectively. So,
      `--track-changes=accept` will show the moved version, while
      `--track-changes=reject` will show the original version.
    + Tests for track-changes moving.
    * ODT, EPUB, Docx readers: throw `PandocError` on unzip failure
    Previously, `readDocx`, `readEPUB`, and `readOdt`
    would error out if zip-archive failed. We change the archive extraction
    step from `toArchive` to `toArchiveOrFail`, which returns an Either value.
    * Markdown, HTML readers:  be more forgiving about unescaped `&` in
    HTML (#2410).  We are now more forgiving about parsing invalid HTML with
    unescaped `&` as raw HTML.  (Previously any unescaped `&`
    would cause pandoc not to recognize the string as raw HTML.)
    * Markdown reader:
    + Fix pandoc title blocks with lines ending in 2 spaces.
    + Added `-s` to markdown-reader-more test.
    * HTML reader: fixed bug in `pClose`.  This caused exponential parsing
    behavior in documnets with unclosed tags in `dl`, `dd`, `dt`.
    * MediaWiki reader: Allow spaces before `!` in MediaWiki table header
    * RST reader: Support `:class:` option for code block in RST reader
    * Org reader:
    + Stop padding short table rows.
      Emacs Org-mode doesn't add any padding to table rows.  The first
      row (header or first body row) is used to determine the column count,
      no other magic is performed.
    + Refactor rows-to-table conversion.  This refactors
      the codes conversing a list table lines to an org table ADT.
      The old code was simplified and is now slightly less ugly.
    + Fix handling of empty table cells, rows.
      This fixes Org mode parsing of some corner cases regarding empty cells
      and rows.  Empty cells weren't parsed correctly, e.g. `|||` should be
      two empty cells, but would be parsed as a single cell containing a pipe
      character.  Empty rows where parsed as alignment rows and dropped from
      the output.
    + Fix spacing after LaTeX-style symbols.
      The org-reader was droping space after unescaped LaTeX-style symbol
      commands: `\ForAll \Auml` resulted in `∀Ä` but should give `∀ Ä`
      instead.  This seems to be because the LaTeX-reader treats the
      command-terminating space as part of the command.  Dropping the trailing
      space from the symbol-command fixes this issue.
    + Print empty table rows.  Empty table rows should not
      be dropped from the output, so row-height is always set to be at least 1.
    + Move parser state into separate module.
      The org reader code has become large and confusing.  Extracting smaller
      parts into submodules should help to clean things up.
    + Add support for sub/superscript export options.
      Org-mode allows to specify export settings via `#+OPTIONS` lines.
      Disabling simple sub- and superscripts is one of these export options,
      this options is now supported.
    + Support special strings export option Parsing of special strings
      (like `...` as ellipsis or `--` as en dash) can be toggled using the `-`
      option.
    + Support emphasized text export option.  Parsing of emphasized text can
      be toggled using the `*` option.  This influences parsing of text marked
      as emphasized, strong, strikeout, and underline.  Parsing of inline math,
      code, and verbatim text is not affected by this option.
    + Support smart quotes export option.  Reading of smart quotes can be
      toggled using the `'` option.
    + Parse but ignore export options. All known export options are parsed
      but ignored.
    + Refactor block attribute handling.  A parser state attribute was used
      to keep track of block attributes defined in meta-lines.  Global state
      is undesirable, so block attributes are no longer saved as part of the
      parser state.  Old functions and the respective part of the parser state
      are removed.
    + Use custom `anyLine`.  Additional state changes need to be made after
      a newline is parsed, otherwise markup may not be recognized correctly.
      This fixes a bug where markup after certain block-types would not be
      recognized.
    + Add support for `ATTR_HTML` attributes.
      Arbitrary key-value pairs can be added to some block types using a
      `#+ATTR_HTML` line before the block.  Emacs Org-mode only includes these
      when exporting to HTML, but since we cannot make this distinction here,
      the attributes are always added.  The functionality is now supported
      for figures.
    + Add `:PROPERTIES:` drawer support.
      Headers can have optional `:PROPERTIES:` drawers associated with them.
      These drawers contain key/value pairs like the header's `id`.  The
      reader adds all listed pairs to the header's attributes; `id` and
      `class` attributes are handled specially to match the way `Attr` are
      defined.  This also changes behavior of how drawers of unknown type
      are handled.  Instead of including all unknown drawers, those are not
      read/exported, thereby matching current Emacs behavior.
    + Use `CUSTOM_ID` in properties.  See above on Org writer changes.
    + Respect drawer export setting.  The `d` export option can be used
      to control which drawers are exported and which are discarded.
      Basic support for this option is added here.
    + Ignore leading space in org code blocks.
      Also fix up tab handling for leading whitespace in code blocks.
    + Support new syntax for export blocks.  Org-mode version 9
      uses a new syntax for export blocks.  Instead of `#+BEGIN_<FORMAT>`,
      where `<FORMAT>` is the format of the block's content, the new
      format uses `#+BEGIN_export <FORMAT>` instead.  Both types are
      supported.
    + Refactor `BEGIN...END` block parsing.
    + Fix handling of whitespace in blocks, allowing content to be indented
      less then the block header.
    + Support org-ref style citations.  The *org-ref* package is an
      org-mode extension commonly used to manage citations in org
      documents.  Basic support for the `cite:citeKey` and
      `[[cite:citeKey][prefix text::suffix text]]` syntax is added.
    + Split code into separate modules, making for cleaner code and
      better decoupling.
    * Added `docbook5` template.
    * `--mathjax` improvements:
    + Use new CommonHTML output for MathJax (updated default MathJax URL)
    + Change default mathjax setup to use `TeX-AMS_CHTML` configuration.
      This is designed for cases where the input is always TeX and maximal
      conformity with TeX is desired.  It seems to be smaller and load faster
      than what we used before.  See #2858.
    + Load the full MathJax config to maximize loading speed.
    * Require texmath 0.8.6.2.  Closes several texmath-related bugs
    This fixes behavior of roots, e.g.
    `\sqrt[3]{x}`, and issues with sub/superscript positioning
    and matrix column alignment in docx.
    * README:
    + Clarified documentation of `implicit_header_references`.
    + Improved documentation of `--columns` option.
    * Added appveyor setup, with artefacts.
    * stack.yaml versions: Use proper flags used for texmath, pandoc-citeproc.
    * LaTeX template: support for custom font families.
    Needed for correct polyglossia operation with Cyrillic fonts and perhaps
    can find some other usages.  Example usage in YAML metadata:
      fontfamilies:
    - name: \cyrillicfont
      font: Liberation Serif
    - name: \cyrillicfonttt
      options: Scale=MatchLowercase
      font: Liberation
* Tue Mar 29 2016 [email protected]
  - update to 1.17.0.3
    * LaTeX writer: Fixed position of label in figures. Previously the label wasn't
      in the right place, and `\ref` wouldn't work properly.
    * Added .tei test files to pandoc.cabal so they'll be included in tarball.
* Fri Mar 25 2016 [email protected]
  - update to 1.17.0.2
    * Fixed serious regression in `htmlInBalanced`, which caused
      newlines to be omitted in some raw HTML blocks in Markdown
    * File scope is no longer used when there are no input files (i.e.,
      when input comes from stdin).  Previously file scope was triggered
      when the `json` reader was specified and input came from `stdin`,
      and this caused no output to be produced.
    * Improved documentation of templates
    * Added `--file-scope` option (Jesse Rosenthal).
      By default pandoc operates on multiple files by first concatenating
      them (around extra line breaks) and then processing the joined file. So
      it only parses a multi-file document at the document scope. This has the
      benefit that footnotes and links can be in different files, but for
      some purposes it is useful to parse the individual files first
      and then combine their outputs (e.g. when the files use footnotes
      or links with the same labels).  The `--file-scope` option causes
      pandoc to parse the files first, and then combine the parsed output,
      instead of combining before parsing. `--file-scope` is selected
      automatically for binary input files (which cannot be concatenated)
      and for pandoc json.
    * Add TEI Writer (Chris Forster) and `tei` output format.
    * Added a general `ByteStringReader` with warnings, used by the docx
      reader (API change, Jesse Rosenthal).
    * Add `readDocxWithWarnings` (API change, Jesse Rosenthal).
    * Changed type of `Shared.uniqueIdent`'s argument from `[String]`
      to `Set String.` This avoids performance problems in documents with
      many identically named headers (API change, #2671).
    * Removed `tex_math_single_backslash` from `markdown_github` options
    * Make language extensions as well as full language names
      trigger syntax highlighting.  For example, `py` will now work as
      well as `python` (jgm/highlighting-kate#83).
    * Added `institute` variable to latex, beamer templates (Fraser
      Tweedale, Josef Svenningsson).
    * Docx reader (Jesse Rosenthal):
      + Handle alternate content.  Some word functions (especially graphics)
      give various choices for content so there can be backwards compatibility.
      + Don't turn numbered headers into lists.
      + Docx Reader: Add state to the parser, for warnings
      + Update feature checklist in source code.
      + Get rid of `Modifiable` typeclass.
      + Add tests for adjacent hyperlinks.
      + Add a "Link" modifier to `Reducible`. We want to make sure that
      links have their spaces removed, and are appropriately smushed
      together (#2689).
    * HTML reader:
      + Fixed behavior of base tag (#2777).
      If the base path does not end with slash, the last component
      will be replaced.  E.g. base = `http://example.com/foo`
      combines with `bar.html` to give `http://example.com/bar.html`.
      If the href begins with a slash, the whole path of the base
      is replaced.  E.g. base = `http://example.com/foo/` combines
      with `/bar.html` to give `http://example.com/bar.html`.
      + Rewrote `htmlInBalanced`.  This version avoids an exponential
      performance problem with `<script>` tags, and it should be faster
      in general (#2730).
      + Properly handle an empty cell in a simple table (#2718).
      + Handle multiple `<meta>` tags with same name.  Put them in a list
      in the metadata so they are all preserved, rather than (as before)
      throwing out all but one..
    * Markdown reader:
      + Improved pipe table parsing (#2765).
      + Allow `+` separators in pipe table cells.  We already allowed
      them in the header, but not in the body rows, for some reason.
      This gives compatibility with org-mode tables.
      + Don't cross line boundary parsing pipe table row.
      Previously an Emph element could be parsed across the newline
      at the end of the pipe table row.
      + Use `htmlInBalanced` for `rawVerbatimBlock`, for better
      performance (#2730).
      + Fixed bug with smart quotes around tex math.
    * LaTeX reader:
      + Handle interior `$` characters in math (#2743).  For example,
      `$$\hbox{$i$}$$`.
      + `inlineCommand` now gobbles an empty `{}` after any command (#2687).
      This gives better results when people write e.g. `\TeX{}` in Markdown.
      + Properly handle LaTeX "math" environment as inline math (#2171).
    * Textile reader: Support `>`, `<`, `=`, `<>` text alignment attributes.
    * Org reader (Albert Krewinkel):
      + Prefix even empty figure names with "fig:" (#2643).  The
      convention used by pandoc for figures is to mark them by prefixing
      the name with `fig:`.  The org reader failed to do this if a figure
      had no name.
      + Refactor link-target processing (#2684).
    * ConTeXt writer: Fix whitespace at line beginning in line blocks (#2744).
      Thanks to @c-foster.
    * HTML writer: Don't include alignment attribute for default table columns.
      Previously these were given "left" alignment.  Better to leave off
      alignment attributes altogether (#2694).
    * Markdown writer: Use hyphens for YAML metadata block bottom line, for
      better compatibility with other Markdown flavors (Henrik Tramberend).
    * LaTeX writer:
      + Use image identifier to create a label and hypertarget for
      figures (Mauro Bieg).
      + Avoid double toprule in headerless table with caption (#2742).
      + Clean up options parser (Jesse Rosenthal).
      + Treat `memoir` template with `article` option as article, instead
      of treating all `memoir` templates as books.
      + Allow more flexible table alignment (Henrik Tramberend, #2665).
      New default is not to include `[c]` option (which is the default
      anyway if no positioning is specified).  Now LaTeX emplates can
      control the overall table alignment in a document by setting the
      longtable length variables `LTleft` and `LTright`.  For example,
      `\setlength\LTleft\parindent\setlength\LTright\fill`
      will create left-aligned tables that respect paragraph indentation.
    * Docx writer: Handle image alt text (#2754, Mauro Bieg).
    * Org writer - pass through RawInline with format "org".
    * DokuWiki writer: use `$$` for display math.
    * Custom writer: Pass attributes parameter to CaptionedImage (#2697).
    * Make protocol-relative URIs work again (#2737).
    * make_osx_package.sh:  Use env variable for developer id certs.
    * Raise `tagsoup` lower bound to 0.13.7 to fix entity-related
      problems (#2734).
    * Allow `zip-archive` 0.3.
    * Allow `aeson` 0.11.

* Sun Oct 25 2015 [email protected]
  - update to 1.15.1.1
    * `Text.Pandoc.Data`:  store paths in dataFiles using posix separators.
    + add Suggests: texlive-latex-bin-bin
* Sun Oct 18 2015 [email protected]
  - update to 1.15.1
    * `pandocVersion` is now defined in `Text.Pandoc.Shared`
      and reexported from `Text.Pandoc` (Alex Vong).  This allows
      writers to access it.  (Alex Vong) (API change)
    * For `markdown_mmd`, add: `implicit_figures`, `superscripts`,
      `subscripts` (#2401).
    * Added `odt` as input format (MarLinn).  Added new module
      `Text.Pandoc.Reader.ODT` (API change). Fully implemented features:
      Paragraphs, Headers, Basic styling, Unordered lists, Ordered lists,
      External Links, Internal Links, Footnotes, Endnotes, Blockquotes.
      Partly implemented features: Citations, Tables.
    * Markdown Reader:
      + Add basic tests for each header style (Ophir Lifshitz).
      + Add implicit header ref tests for headers with spaces (Ophir Lifshitz).
      + Skip spaces in headers (Ophir Lifshitz).
      + Handle 'id' and 'class' in parsing key/value attributes (#2396).
      `# Header {id="myid" class="foo bar"}`
      is now equivalent to `# Header {#myid .foo .bar}`.
      + Use '=' instead of '#' for atx-style headers in markdown+lhs.
      (Kristof Bastiaensen)
      + Pipe tables: allow indented columns.  Previously the left-hand column
      could not start with 4 or more spaces indent.  This was inconvenient
      for right-aligned left columns.  Note that the first (header column)
      must still have 3 or fewer spaces indentation, or the table will be
      treated as an indented code  block.
      + Fix regression:  allow HTML comments containing `--`.
      Technically this isn't allowed in an HTML comment, but
      we've always allowed it, and so do most other implementations.
      It is handy if e.g. you want to put command line arguments
      in HTML comments.
    * LaTeX reader:
      + Don't eat excess whitespace after macros with only optional
      arguments (#2446).
      + Support longtable (#2411).
      + Implement `\Cite` (#2335).
      + Support abstract environment.  The abstract populates an
      `abstract` metadata field.
      + Properly handle booktabs lines.  Lines aren't part of the
      pandoc table model, so we just ignore them (#2307).
    * HTML reader:
      + Handle type attribute on ol, e.g. `<ol type="i">` (#2313).
      + Updated for new automatic header attributes.
      + Add auto identifiers if not present on headers.  This makes
      TOC linking work properly.
      + Detect `font-variant` with `pickStyleAttrProps` (Ophir Lifshitz).
      + Test `<ol>` type, class, and inline list-style(-type) CSS
      (Ophir Lifshitz).
      + Better handling of "section" elements (#2438).  Previously
      `<section>` tags were just parsed as raw HTML blocks.  With
      this change, section elements are parsed as Div elements with
      the class "section".
    * MediaWiki reader:  handle unquoted table attributes (#2355).
    * DocBook reader:
      + Added proper support for DocBook `xref` elements (Frerich Raabe).
      Added `dbContent` field to reader state, so we can lookup
      cross refs.
      + Handle `informalexample` (#2319).
    * Docx Reader:
      + Create special punctuation test (Ophir Lifshitz).
      + Parse soft, no-break hyphen elements (Ophir Lifshitz).
      + Updated headers test (Ophir Lifshitz). Replaced `styles.xml`
      in `headers.docx` with pandoc's current `styles.xml`, which
      contains styles for Heading 1 through 6. Added Heading 4
      through 7 to the test document. Note that Heading 7 is not
      parsed as a Heading because there is no Heading 7 style.
    * RST reader:  better handling of indirect roles.
      Previously the parser failed on this kind of case
      .. role:: indirect(code)
      .. role:: py(indirect)
      :language: python
      :py:`hi`
      Now it correctly recognizes `:py:` as a code role.
    * Org reader:
      + Add auto identifiers if not present on headers
      (#2354, Juliusz Gonera).
      + Allow verse blocks to contain empty lines (#2402,
      Albert Krewinkel).
    * EPUB reader:  stop mangling external URLs (#2284).
    * RST writer:
      + Don't insert `\ ` when complex expression in matched pairs.
      E.g. `` [:sup:`3`] `` is okay; you don't need `` [:sup:`3`\ ] ``.
      + Ensure that `\ ` is inserted when needed before Cite and Span
      elements that begin with a "complex" element (jgm/pandoc-citeproc#157).
      + Normalize headers only in "standalone" mode (#2394).
    * Haddock writer: escape `*` and `^` (G. Bataille).
    * Markdown writer:
      + In TOC, add links to headers (#829).
      + Use unicode super/subscripts for digits in plain output
      (when the `superscripts` and `subscripts` extensions are
      not enabled).
    * Docx writer:
      + Moved invalid character stripping to `formattedString`.
      This avoids an inefficient generic traversal (#2356).
      + Use user data directory for `reference.docx` archive.
      This allows the test suite to work without installing pandoc first.
      It also brings the docx writer in line with the odt writer.
      + Tests:  docx writer tests now use `../data` for data directory.
      This allows tests to be run without installing first.
      + Tests: Use real jpg (not empty) for docx tests to avoid warning.
    * LaTeX writer:
      + Fixed detection of 'chapters' from template.
      If a documentclass isn't specified in metadata, but the
      template has a hardwired bookish documentclass, act as if
      `--chapters` was used.  This was the default in earlier
      versions, but it has been broken for a little while.
      + Correctly recognize book documentclass in metadata (#2395).
      + Set language-related variables automatically, depending
      on the value of the `lang` field, which is now always
      assumed to be in BCP47 format (mb21, #1614, #2437).
      + Add `\protect` to `\hyperdef` in inline context.  This way we
      don't get an error when this is used as a moveable argument (#2136).
      + Support all frame attributes in Beamer.
      + Percent-encode more special characters in URLs (#1640, #2377).
      The special characters are '<','>','|','"','{','}','[',']','^', '`'.
    * HTML writer:
      + Update KaTeX JS and CSS versions (Emily Eisenberg).
      + For dzslides, add `role="note"` for speaker notes (#1693).
      + Percent-encode more special characters in URLs (#1640, #2377).
      The special characters are '<','>','|','"','{','}','[',']','^', '`'.
      + Render Div with class `section` as `<section>` in HTML5.
    * EPUB writer:
      + In TOC, replace literal "<br/>" with space (#2105).
      + With `--webtex`, include image file rather than `data:` URI (#2363).
    * Native writer: format Div properly, with blocks separated.
    * Support bidirectional text output with XeLaTeX, ConTeXt and HTML
    * Reference Docx:
      + Add missing Header 6 style (steel blue) (Ophir Lifshitz).
      + Correct `outlineLvl` for Header styles (Ophir Lifshitz).
    * Templates
      + Beamer:  Add `innertheme`, `outertheme` variables
      (Guilhem Bonnefille, #121). Add space after colon in figure caption.
      Integrate recent font and language updates from LaTeX template;
      allow use of `mainfont` variable for changing the slide text
      in XeTeX and LuaTeX (Andrew Dunning, #131).
      + LaTeX:  Add `mainfontoptions`, `sansfontoptions`,
      `monofontoptions`, `mathfontoptions`, `fontfamilyoptions`
      (Andrew Dunning, #122).  Support handling of bidirectional
      text (mb21, #120). Improve reliability of superscripts/subscripts
      under XeTeX and prevent letters and numbers from appearing on a
      different baseline by removing use of the `realscripts` package
      (via `xltxtra`).  To restore use of OpenType characters for these
      features under XeTeX or LuaTeX, add `\usepackage{realscripts}` to
      `header-includes` (Andrew Dunning, #130).  Remove redundant
      reference to `xunicode` (Andrew Dunning, #130).  Add `fontenc`,
      `indent`, `subparagraph` variables (Andrew Dunning).
      Allow use of `hidelinks` variable for `hyperref` package (Hugo Roy,
      [#113]).  Prevent package clash with `tufte-latex` and other classes that
      include `hyperref` or `color` (Xavier Olive, #115).
      + ConTeXt:  Support handling of bidirectional text (mb21, #120).
      + LaTeX and ConTeXt: Use more specific language variables.
      Instead of directly using `lang`, we now use `babel-lang` and
      `polyglossia-lang` and `context-lang`.  These variables are set by
      the writers to the necessary values, based on the `lang` variable
      (which now always takes a value in BCP47 format). (mb21, #114, #129).
      + HTML:  Support handling of bidirectional text (mb21, #120).
      Move HTML5 shiv after CSS and fix URL (Andrew Dunning).
      Add dir attribute in html5 (Andrew Dunning).
      + reveal.js: Add `controls`, `progress` variables (Grégoire Pineau, #127).
      Add `width`, `height` variables (Anrew Dunning).  Update template
      from 3.1 source (Andrew Dunning).  All configuration options are now
      available as variables, but are only be included if set (reveal.js
      uses defaults otherwise).
      + man: Added comment stating that the page is autogenerated by pandoc,
      giving version.  Added `adjusting` and `hyphenate` variables
      (Alex Vong, #123).
    * epub.css: added selectors for nested emphasis (Pablo Rodriguez).
    * MediaBag:  ensure that `/` is always used as path separator.
    * `sample.lua`: define `CaptionedImage`, add newline at end (#2393).
    * Added `--bash-completion` option.  This generates a bash completion
      script.  To use: `eval "$(pandoc --bash-completion)"`.
    * Text.Pandoc.Error: Define Typeable and Exception instances
      for PandocError (#2386).
    * Text.Pandoc.Parsing: `toKey`: strip off outer brackets.
      This makes keys with extra space at the beginning and end
      work:  e.g.
      [foo]: bar
      [ foo ]
      will now be a link to bar (it wasn't before).
    * Text.Pandoc: disable `auto_identifiers` for epub.
      The epub writer inserts its own auto identifiers;
      this is more complex due to splitting into "chapter" files.
    * Renamed Text.Pandoc.Compat.Locale -> Text.Pandoc.Compat.Time.
      It now reexports Data.Time.
    * Use custom Prelude to avoid compiler warnings.
      + The (non-exported) prelude is in prelude/Prelude.hs.
      + It exports Monoid and Applicative, like base 4.8 prelude,
      but works with older base versions.
      + It exports (<>) for mappend.
      + It hides 'catch' on older base versions.
    * Added a `stack.ymal` and stack install instructions to INSTALL.
    * Clarified what is "out of scope" in README and CONTRIBUTING.md.
    * Added note to CONTRIBUTING.md about ghc versions and travis.
    * Clarify docs on block quotes.  The space after `>` is optional (#2346).
    * Removed obsolete reference to default.csl (#2372).
    * List all styles in manual for `--reference-docx` (Chris Black)
    * Don't capitalize header links in man page.
    * Added section on repl to CONTRIBUTING.md.
    * README:  Added space after backslash in image example (#2329).
    * Document details of citation locator terms (Nick Bart).
    * Fixed some internal links in README (#2309).
    * Improve CSL documentation, variables documentations,
      links, and cross-references in README. (Andrew Dunning)
    * Fix build failure with `--flags=-https` (Sergei Trofimovich).
    * Use `newManager` instead of `withManager` in recent `http-client`.
      This avoids a deprecation warning.
    * Allow building with latest versions of http-types,
      HUnit, criterion, syb, aeson.
    * Setup.hs: rewrite so as not to use process, directory, filepath.
      Using anything outside base is dangerous, since older
      versions of ghc may link against two different versions.
* Tue Jul 28 2015 [email protected]
  - update to 1.15.0.6
  - removed man.patch , pandoc.1.gz and pandoc_markdown.5.gz
    * `--self-contained`:  Fixed overaggressive CSS minimization (#2301, 2286).
      Previously `--self-contained` wiped out all spaces in CSS,
      including semantically significant spaces.  This was a regression
      from 1.14.x.
    * Markdown reader: don't allow bare URI links or autolinks in link
      label (#2300).  Added test cases.
    * `Text.Pandoc.Parsing`, `uri`: Improved bare autolink detection (#2299).
      Previously we disallowed `-` at the end of an autolink,
      and disallowed the combination `=-`.  This commit liberalizes the
      rules for allowing punctuation in a bare URI, and adds test cases.
      One potential drawback is that you can no longer put a bare
      URI in em dashes like this:
      `this uri---http://example.com---is an example.`
      But in this respect we now match github's treatment of bare URIs.
    * HTML writer:  support speaker notes in dzslides.
      With this change `<div class="notes">` and also `<div class="notes"
      role="note">` will be output if `-t dzslides` is used. So we can
      have speaker notes in dzslides too.  Thanks to maybegeek.
    * Updated dzslides template.
    * Improved documentation of options to print system default files (#2298).
      `--print-default-data-file` and `--print-default-template`.
    * DokuWiki writer: use `$..$` for Math instead of `<math>..</math>`
      (Tiziano Müller).  MathJax seems currently to be the only maintained
      math rendering extension for DokuWiki.
    * `Text.Pandoc.Shared`: Changed `hierarchicalize` so it treats references
      div as top-level header (#2294).  This fixes a bug with `--section-divs`,
      where the final references section added by pandoc-citeproc, enclosed in
      its own div, got nested in the div for the section previous to it.
    * Allow vector 0.11.
    * Require cmark > 0.4.
    * HTML writer: Fixed email javascript obfuscation with `mailto:`
      URLs (#2280).  This fixes a potential security issue.  Because
      single quotes weren't being escaped in the link portion, a
      specially crafted email address could allow javascript code injection.
    * Markdown/HTML readers:  Avoid parsing partial URLs like
      `<www.pandoc.org/blah#foo>` as HTML tags (#2277).
    * RST reader:  allow inline formatting in definition list field
      names (Lars-Dominik Braun).
    * PDF:  Make sure `--latex-engine-opt` goes before the filename
      on the command line.  LaTeX needs the argument to come after
      the options (#1779).
    * CommonMark writer: fixed tags used for super/subscript.
    * ConTeXt template:  activate hanging indent for definition lists
      (mb21).
    * Make cabal require `hsb2hs` >= 0.3.1 if `embed_data_files` specified.
      This is done by adding `hookedPrograms` in `Setup.hs`, which allows us
      to include `hsb2hs` in Build-Tools in cabal.
      + Admin privileges are no longer required for a per-user install
    * Travis:  unpack sdist for build to catch packaging bugs.
    * Improved documentation on where user templates go (#2272).
    * Added pandoc.1 man page to the repository.  It is no longer
      built as part of the cabal build process. (This proved too
      fragile.)  pandoc.1 can be regenerated (`make man/pandoc.1`)
      when `README` is changed.
    * Copying of the man page now respects `--destdir` (#2262).
    * Improved error messages for filters.  User is now informed if
      the filter requires an interpreter that isn't found in the path,
      or if the filter returns an error status.
    * Ensure target directory is created when installing man page.
    * Added files needed for building man page to Extra-Source-Files.
    * Man page is now built and installed as part of the cabal build
      process. Removed Makefile target for man page.
    * Man page changes:
      + Removed `--man1`, `--man5` options (breaking change).
      + Removed `Text.Pandoc.ManPages` module (breaking API change).
      + Makefile target for `man/man1/pandoc.1`.  This uses pandoc to
      create the man page from README using a custom template and filters.
      + Added `man/` directory with template and filters needed to build
      man page.
      + We no longer have two man pages: `pandoc.1` and `pandoc_markdown.5`.
      Now there is just pandoc.1, which has all the content from README.
      This change was needed because of the extensive cross-references
      between parts of the README.
      + Removed old `data/pandoc.1.template` and
      `data/pandoc_markdown.5.template`.
    * OpenDocument writer: Do not add a carriage return after a hard
      line break (Michael Chladek).
    * ConTeXt writer:
      + use `\goto` for internal links.
      + Added a `%` at end for `\reference` to avoid spurious space.
    * Ignore sandbox on 'make quick'
    * Added new unexported module:  `Text.Pandoc.ManPages`.
    * `README` now acts like a data file (even though it isn't in
      `data/`).  So, for example, `pandoc --print-default-data-file README`
      will produce the README.)  This change was required for the `--man1`
      and `--man5` options, since the man pages are produced from the
      README, but it may be useful for other purposes as well.
    * Allow `reference.docx` and `reference.odt` to be used with
      `--print-default-data-file` and to shadow defaults if placed in
      the user data directory.  Note that as of 1.14, we no longer
      include these files as data files; instead, we include their
      components.  This change causes pandoc to behave as if it has
      these data files; they are constructed on demand when needed
      using `getDefaultReferenceDocx` and `getDefaultReferenceODT`.
    * Fixed regression in CSS parsing with `--self-contained` (#2224).
      Pandoc 1.14.0.x used css-text to parse the CSS, but its parser
      silently drops big sections of CSS.  This commit replaces the
      use of css-text with a small but principled CSS preprocessor,
      which removes whitespace and comments and replaces `url()` with
      base 64 data when possible.
    * Use `https://` instead of `//` for MathJax and KaTeX CDN URLs (#1920).
      This will allow math to work when pages are being viewed locally.
    * `Text.Pandoc.Options`:  Export `plainExtensions`.
      These are the extensions used in `plain` output.
    * LaTeX reader: Don't parse `_` and `^` as sub/superscript outside of
      math mode; treat them as regular inline text.  Normally these will
      cause an error in LaTeX, but there are contexts (e.g. `alltt`
      environments) where they are allowed.
    * HTML reader:  allow `<body>` to close `<head>`.
    * DocBook reader: support `mediaobject`s and `figures` (#2184, mb21).
    * RST reader: Fix reference names with special characters
      (Lars-Dominik Braun).
    * Textile writer:  escape `+` and `-` as entities (#2225).
    * DokuWiki writer: Use proper `<code>` tags for code blocks (#2213).
    * Plain writer:  don't use symbols for super/subscript (#2237).
      Simplified code by using `plainExtensions`.
    * InDesign writer: Properly escape URLs containing more than one
      colon character (gohai).
    * Docx writer: Make sure we use dist version of `reference.docx`
      (and not the user's version) for certain settings.  Taking some
      settings values from a user-supplied reference.docx can lead to
      corruption.  This fixes a regression from the last release (#2249).
    * `Text.Pandoc.Shared`: exports `getDefaultReferenceDocx` and
      `getDefaultReferenceODT` (API change).  These functions have been
      removed from the Docx and ODT writers.
    * LaTeX template (Xavier Olive):
      + Added `CJKmainfont` and `CJKoptions` variables.
      + Allow dvipsnames (e.g. `MidnightBlue`) for colors (Xavier Olive).
    * Epub templates:  use `author.role`, not `author.type`.
    * Bump cmark version to >= 0.3.4.
    * Improved Windows installer (#2205, thanks to nkalvi).
      Users can now select a per-user or systemwide install, and can set
      the installation path.  At the end of installation, the install location
      is given.  The install location is also now given in the list of
      installed programs in Control Panel.  Cleaner WiX syntax is used for
      setting the path.
    * Added `download_stats` target to Makefile.
* Thu Jun 04 2015 [email protected]
  - update to 1.14.0.4
    * Added missing commonmark template.
* Tue Jun 02 2015 [email protected]

    pandoc (1.13.2)
    ===============
    * TWiki Reader: add new new twiki reader (API chaneg, Alexander Sulfrian).
    * Markdown reader:
      + Better handling of paragraph in div (#1591).
      Previously text that ended a div would be parsed as Plain
      unless there was a blank line before the closing div tag.
      + Don't treat a citation as a reference link label (#1763).
      + Fix autolinks with following punctuation (#1811).
      The price of this is that autolinked bare URIs can no longer
      contain `>` characters, but this is not a big issue.
      + Fix `Ext_lists_without_preceding_blankline` bug (#1636, Artyom).
      + Allow `startnum` to work without `fancy_lists`. Formerly
      `pandoc -f markdown-fancy_lists+startnum` did not work properly.
    * RST reader (all Daniel Bergey):
      + Parse quoted literal blocks (#65).  RST quoted literal blocks are
      the same as indented literal blocks (which pandoc already supports)
      except that the quote character is preserved in each line.
      + Parse RST class directives. The class directive accepts one or more
      class names, and creates a Div value with those classes.  If the
      directive has an indented body, the body is parsed as the children of
      the Div.  If not, the first block folowing the directive is made a
      child of the Div. This differs from the behavior of rst2xml, which
      does not create a Div element.  Instead, the specified classes are
      applied to each child of the directive.  However, most Pandoc Block
      constructors to not take an Attr argument, so we can't duplicate this
      behavior.
      + Warn about skipped directives.
      + Literal role now produces Code. Code role should have "code" class.
      + Improved support for custom roles
    - Added `sourceCode` to classes for `:code:` role, and anything
      inheriting from it.
    - Add the name of the custom role to classes if the Inline
      constructor supports Attr.
    - If the custom role directive does not specify a parent role,
      inherit from the `:span:` role.
      This differs somewhat from the `rst2xml.py` behavior.  If a custom
      role inherits from another custom role, Pandoc will attach both
      roles' names as classes.  `rst2xml.py` will only use the class of
      the directly invoked role (though in the case of inheriting from a
      `:code:` role with a `:language:` defined, it will also provide the
      inherited language as a class).
      + Warn about ignored fields in role directives.
    * LaTeX reader:
      + Parse label after caption into a span instead of
      inserting an additional paragraph of bracketed text (#1747).
      + Parse math environments as inline when possible (#1821).
      + Better handling of `\noindent` and `\greektext` (#1783).
      + Handle `\texorpdfstring` more gracefully.
      + Handle `\cref` and `\sep` (Wikiwide).
      + Support `\smartcite` and `\Smartcite` from biblatex.
    * HTML reader:
      + Retain display type of MathML output (#1719, Matthew Pickering).
      + Recognise `<br>` tags inside `<pre>` blocks (#1620, Matthew Pickering).
      + Make `embed` tag either block or inline (#1756).
    * DocBook reader:
      + Handle `keycombo`, `keycap` (#1815).
      + Get string content in inner tags for literal elements (#1816).
      + Handle `menuchoice` elements better, with a `>` between (#1817).
      + Include `id` on section headers (#1818).
      + Document/test "type" as implemented (Brian O'Sullivan).
      + Add support for calloutlist and callout (Brian O'Sullivan).
      We treat a calloutlist as a bulleted list. This works well in practice.
      + Add support for `classname` (Bryan O'Sullivan).
    * Docx reader:
      + Fix window path for image lookup (Jesse Rosenthal).
      Don't use os-sensitive "combine", since we always want the paths in our
      zip-archive to use forward-slashes.
      + Single-item headers in ordered lists are headers (Jesse Rosenthal).
      When users number their headers, Word understands that as a single item
      enumerated list. We make the assumption that such a list is, in fact,
      a header.
      + Rewrite rewriteLink to work with new headers (Jesse Rosenthal).
      There could be new top-level headers after making lists, so we have to
      rewrite links after that.
      + Use polyglot header list (Jesse Rosenthal).
      We're just keeping a list of header formats that different languages
      use as their default styles. At the moment, we have English, German,
      Danish, and French. We can continue to add to this.
      This is simpler than parsing the styles file, and perhaps less
      error-prone, since there seems to be some variations, even within a
      language, of how a style file will define headers.
      + Remove header class properly in other langs (Jesse Rosenthal).
      When we encounter one of the polyglot header styles, we want to remove
      that from the par styles after we convert to a header. To do that, we
      have to keep track of the style name, and remove it appropriately.
      + Account for external link URLs with anchors. Previously, if a URL
      had an anchor, the reader would incorrectly identify it as an
      internal link and return only the anchor as URL. (Caleb McDaniel)
      + Fix for Issue #1692 (i18n styles) (Nikolay Yakimov).
    * Org reader:
      + Added state changing blanklines (Jesse Rosenthal).
      This allows us to emphasize at the beginning of a new paragraph (or, in
      general, after blank lines).
      + Fixed bug with bulleted lists:
    - a
    - b
    * c
      was being parsed as a list, even though an unindented `*`
      should make a heading.  See
      <http://orgmode.org/manual/Plain-lists.html#fn-1>.
      + Org reader: absolute, relative paths in link (#1741, Albert
      Krewinkel). The org reader was too restrictive when parsing links;
      some relative links and links to files given as absolute paths
      were not recognized correctly.
      + Org reader:  allow empty links (jgm/gitit#471, Albert Krewinkel).
      This is important for use in gitit, which uses empty links
      for wikilinks.
      + Respect indent when parsing Org bullet lists (#1650, Timothy
      Humphries).  Fixes issue with top-level bullet list parsing.
      + Fix indent issue for definition lists (Timothy Humphries,
      see #1650, #1698, #1680).
      + Parse multi-inline terms correctly in definition list (#1649,
      Matthew Pickering).
      + Fix rules for emphasis recognition (Albert Krewinkel).
      Things like `/hello,/` or `/hi'/` were falsy recognized as emphasised
      strings.  This is wrong, as `,` and `'` are forbidden border chars and
      may not occur on the inner border of emphasized text.
      + Drop COMMENT document trees (Albert Krewinkel).
      Document trees under a header starting with the word `COMMENT` are
      comment trees and should not be exported.  Those trees are dropped
      silently (#1678).
      + Properly handle links to `file:target` (Albert Krewinkel).
      Org links like `[[file:target][title]]` were not handled correctly,
      parsing the link target verbatim.  The org reader is changed such that
      the leading `file:` is dropped from the link target (see #756, #1812).
      + Parse LaTeX-style MathML entities (#1657, Albert Krewinkel).
      Org supports special symbols which can be included using LaTeX syntax,
      but are actually MathML entities.  Examples for this are
      `\nbsp` (non-breaking space), `\Aacute` (the letter A with accent acute)
      or `\copy` (the copyright sign ©)
    * EPUB reader:
      + URI handling improvements. Now we outsource most of the work to
      `fetchItem'`. Also, do not include queries in file extensions (#1671).
    * LaTeX writer:
      + Use `\texorpdfstring` for section captions when needed (Vaclav Zeman).
      + Handle consecutive linebreaks (#1733).
      + Protect graphics in headers (Jesse Rosenthal).
      Graphics in `\section`/`\subsection` etc titles need to be `\protect`ed.
      + Put `~` before header in list item text (Jesse Rosenthal).
      Because of the built-in line skip, LaTeX can't handle a section header
      as the first element in a list item.
      + Avoid using reserved characters as `\lstinline` delimiters (#1595).
      + Better handling of display math in simple tables (#1754).
      We convert display math to inline math in simple tables,
      since LaTeX can't deal with display math in simple tables.
      + Escape spaces in code (#1694, Bjorn Buckwalter).
    * MediaWiki writer:
      + Fixed links with URL = text. Previously these were rendered as bare
      words, even if the URL was not an absolute URL (#1825).
    * ICML writer:
      + Don't force all citations into footnotes.
    * RTF writer:
      + Add blankline at end of output (#1732, Matthew Pickering).
    * RST writer:
      + Ensure blank line after figure.
      + Avoid exces whitespace after last list item (#1777).
      + Wrap line blocks with spaces before continuations (#1656).
      + Fixed double-rendering of footnotes in RST tables (#1769).
    * DokuWiki writer:
      + Better handling of block quotes. This change ensures that
      multiple paragraph blockquotes are rendered using native `>`
      rather than as HTML (#1738).
      + Fix external images (#1739). Preface relative links with ":",
      absolute URIs without. (Timothy Humphries)
    * HTML writer:
      + Use protocol-relative URL for mathjax.
      + Put newline btw img and caption paragraph.
      + MathML now outputted with tex annotation (#1635, Matthew Pickering).
      + Add support for KaTeX HTML math (#1626, Matthew Pickering).
      This adds `KaTeX` to `HTMLMathMethod` (API change).
      + Don't double render when `email-obfuscation=none` (#1625, Matthew
      Pickering).
      + Make header attributes work outside top level (#1711).
      Previously they only appeared on top level header elements.
      Now they work e.g. in blockquotes.
    * ODT writer:
      + Correctly handle images without extensions (#1729).
      + Strip querystring in ODT write (#1682, Todd Sifleet).
    * FB2 writer:
      + Add newline to output.
    * EPUB writer:
      + Don't add `sourceURL` to absolute URIs (#1669).
      + Don't use unsupported `opf:title-type` for epub2.
      + Include "landmarks" section in nav document for epub3 (#1757).
      + Removed playOrder from navpoint elements in ncx file (#1760).
      These aren't required, and they make manual modification of epubs
      difficult.
      + Extract title even from structured title.
      + Don't include nav node in spine unless `--toc` was requested.
      Previously we included it in the spine with `linear="no"`, leading
      to odd results in some readers (#1593).
      + Fixed absolute URI detection (#1672).
      + Correctly resolve relative URIs (#1671).
      + Use regular page template for `nav.xhtml`, including doctype (#1759).
    * Docx writer:
      + Put docx table captions above tables (#1641, Nikolay Yakimov).
      + Get the page width from the reference docx file, and use
      it to scale images that are too large to fit (Grégory Bataille).
      + Partial fix for #1607 (Nikolay Yakimov). International heading styles
      are inferred based on `<w:name val="heading #">` fallback, if there
      are no en-US "Heading#" styles
      + Look in user data dir for archive `reference.docx`.
      + Renumber header and footer relationships to avoid collisions (Jesse
      Rosenthal). We previously took the old relationship names of the
      headers and footer in secptr. That led to collisions. We now make
      a map of availabl names in the relationships file, and then rename
      in secptr.
    * ConTeXt writer:
      + Add function toLabel (Mark Szepieniec).
      This function can be used to sanitize reference labels so that
      they do not contain any of the illegal characters \#[]",{}%()|= .
      Currently only Links have their labels sanitized, because they
      are the only Elements that use passed labels.
    * `Text.Pandoc.Shared`:
      + Moved import of `toChunks` outside of CPP conditional (#1590).
      + Fix `inDirectory` to reset to the original directory in case
      an exception occurs (Freiric Barral).
    * Templates:
      + LaTeX template: load polyglossia before bibtex (jgm/pandoc-templates#70).
      Thanks to bluebirch.
      + LaTeX template: Added `\VerbatimFootnotes` if there is verbatim in notes
      (#1616).
      + LaTeX template:  Add shorthands=off to babel options (#1648).
      + EPUB, EPUB3 templates: Added `id="cover"` to body of cover page.
      This aids styling, making it possible for example to set 0 margins
      on the title page (#1758).
      + EPUB, EPUB3 templates:  Handle structured metadata on titlepage.
      Previously we just expected 'title', 'subtitle', 'author', 'date'.
      Now we still support those, but also support the format recommended
      for epub metadata in the pandoc README:
    - --
      title:
    - type: main
      text: My Book
    - type: subtitle
      text: An investigation of metadata
      creator:
    - role: author
      text: John Smith
    - role: editor
      text: Sarah Jones

      ...
    * `Text.Pandoc.Templates.getDefaultTemplate`:
      don't fail when called with "fb2" (#1660).
    * `Text.Pandoc.Parsing`:
      + Fixed `inlineMath` so it handles `\text{..}` containing `$`.
      For example: `$x = \text{the $n$th root of $y$}` (#1677).
      + Change `parseFromString` to fail if not all input is consumed.
      (Matthew Pickering)
      + Moved `addWarning` from Markdown reader to `Parsing`, so it can be
      used by more readers (API change, Daniel Bergey).
    * `Text.Pandoc.Pretty`:
      +  Improve performance of `realLength` (Matthew Pickering).
      +  Make CR + BLANKLINE = BLANKLINE. This fixes an extra blank line we
      were getting at the end of markdown fragments (as well as rst, org,
      etc.) (#1705).
    * `Text.Pandoc.MIME`:
      + Add mime type for WebVTT (Jason Ronallo).
      + Changed mime type for `otf` to `application/vnd.ms-opentype` (#1761).
      This is needed for epub3 validation.
    * `Text.Pandoc.MediaBag`:
      + Fix Windows specific path problems (#1597).
    * `Text.Pandoc.Shared`:
      + Make `collapseFilePath` OS-agnostic (Matthew Pickering).
    * Link the test suite using `-threaded`.
      This allows the test suite to be run using `+RTS -N`.
    * Added `network` dependency under `network-uri` flag in test section.
    * Give better error messages when someone tries to convert from
      pdf, doc, odt (#1683).
    * Added `track` to list of tags treated by `--self-contained` (#1664).
    pandoc (1.13.1)
    ===============
    * Fixed `--self-contained` with Windows paths (#1558).
      Previously `C:\foo.js` was being wrongly interpreted as a URI.
    * HTML reader:  improved handling of tags that can be block or inline.
      Previously a section like this would be enclosed in a paragraph,
      with RawInline for the video tags (since video is a tag that can
      be either block or inline):
      <video controls="controls">
      <source src="../videos/test.mp4" type="video/mp4" />
      <source src="../videos/test.webm" type="video/webm" />
      <p>
      The videos can not be played back on your system.<br/>
      Try viewing on Youtube (requires Internet connection):
      <a href="http://youtu.be/etE5urBps_w">Relative Velocity on
      Youtube</a>.
      </p>
      </video>
      This change will cause the video and source tags to be parsed
      as RawBlock instead, giving better output.
      The general change is this:  when we're parsing a "plain" sequence
      of inlines, we don't parse anything that COULD be a block-level tag.
    * Docx reader:
      + Be sensitive to user styles.  Note that "Hyperlink" is
      "blacklisted," as we don't want the default underline styling to be
      inherited by all links by default (Jesse Rosenthal).
      + Read single paragraph in table cell as `Plain` (Jesse Rosenthal).
      This makes to docx reader's native output fit with the way the markdown
      reader understands its markdown output.
    * Textile writer:  Extended the range of cases where native textile
      tables will be used (as opposed to raw HTML):  we now handle any
      alignment type, but only for simple tables with no captions.
    * Txt2Tags reader:
      + Header is now parsed only if standalone flag is set (Matthew Pickering).
      + The header is now parsed as meta information. The first line is the
      `title`, the second is the `author` and third line is the `date`
      (Matthew Pickering).
      + Corrected formatting of `%%mtime` macro (Matthew Pickering).
      + Fixed crash when reading from stdin.
    * EPUB writer:  Don't use page-progression-direction in EPUB2, which
      doesn't support it.  Also, if page-progression-direction not specified
      in metadata, don't include the attribute even in EPUB3; not including it
      is the same as including it with the value "default", as we did before.
      (#1550)
    * Org writer: Accept example lines with indentation at the beginning
      (Calvin Beck).
    * DokuWiki writer:
      + Refactor to use Reader monad (Matthew Pickering).
      + Avoid using raw HTML in table cells; instead, use `\\`
      instead of newlines (Jesse Rosenthal).
      + Properly handle HTML table cell alignments, and use spacing
      to make the tables look prettier (#1566).
    * Docx writer:
      + Bibliography entries get `Bibliography` style (#1559).
      + Implement change tracking (Jesse Rosenthal).
    * LaTeX writer:
      + Fixed a bug that caused a table caption to repeat across all pages
      (Jose Luis Duran).
      + Improved vertical spacing in tables and made it customizable using
      standard lengths set by booktab.  See
      <https://groups.google.com/forum/#!msg/pandoc-discuss/qMu6_5lYy0o/ZAU7lzAIKw0J>
      (Jose Luis Duran).
      + Added `\strut` to fix spacing in multiline tables (Jose Luis Duran).
      + Use `\tabularnewline` instead of `\\` in table cells (Jose Luis Duran).
      + Made horizontal rules more flexible (Jose Luis Duran).
    * Text.Pandoc.MIME:
      + Added `MimeType` (type synonym for `String`) and `getMimeTypeDef`.
      Code cleanups (Artyom Kazak).
    * Templates:
      + LaTeX template: disable microtype protrusion for typewriter font (#1549,
      thanks lemzwerg).
    * Improved OSX build procedure.
    * Added `network-uri` flag, to deal with split of `network-uri` from
      `network`.
    * Fix build dependencies for the `trypandoc` flag, so that they are
      ignored if `trypandoc` flag is set to False (Gabor Pali).
    * Updated README to remove outdated claim that `--self-contained`
      looks in the user data directory for missing files.
    pandoc (1.13.0.1)
    =================
    * Docx writer:
      + Fixed regression which bungled list numbering (#1544), causing
      all lists to appear as basic ordered lists.
      + Include row width in table rows (Christoffer Ackelman, Viktor Kronvall).
      Added a property to all table rows where the sum of column widths
      is specified in pct (fraction of 5000).  This helps persuade Word
      to lay out the table with the widths we specify.
    * Fixed a bug in Windows 8 which caused pandoc not to find the
      `pandoc-citeproc` filter (#1542).
    * Docx reader: miscellaneous under-the-hood improvements (Jesse Rosenthal).
      Most significantly, the reader now uses Builder, leading to some
      performance improvements.
    * HTML reader:  Parse appropriately styled span as SmallCaps.
    * Markdown writer: don't escape `$`, `^`, `~` when `tex_math_dollars`,
      `superscript`, and `subscript` extensions, respectively, are
      deactivated (#1127).
    * Added `trypandoc` flag to build CGI executable used in the online
      demo.
    * Makefile:  Added 'quick', 'osxpkg' targets.
    * Updated README in templates to indicate templates license.
      The templates are dual-licensed, BSD3 and GPL2+.
    pandoc (1.13)
    =============
    * Added `docx` as an input format (Jesse Rosenthal).  The docx
      reader includes conversion of native Word equations to pandoc
      LaTeX `Math` elements.  Metadata is taken from paragraphs at the
      beginning of the document with styles `Author`, `Title`, `Subtitle`,
      `Date`, and `Abstract`.
    * Added `epub` as an input format (Matthew Pickering).  The epub
      reader includes conversion of MathML to pandoc LaTeX `Math`
      elements.
    * Added `t2t` (Txt2Tags) as an input format (Matthew Pickering).
      Txt2tags is a lightweight markup format described at
      <http://txt2tags.org/>.
    * Added `dokuwiki` as an output format (Clare Macrae).
    * Added `haddock` as an output format.
    * Added `--extract-media` option to extract media contained in a zip
      container (docx or epub) while adjusting image paths to point to the
      extracted images.
    * Added a new markdown extension, `compact_definition_lists`, that
      restores the syntax for definition lists of pandoc 1.12.x, allowing
      tight definition lists with no blank space between items, and
      disallowing lazy wrapping.  (See below under behavior changes.)
    * Added an extension `epub_html_exts` for parsing HTML in EPUBs.
    * Added extensions `native_spans` and `native_divs` to activate
      parsing of material in HTML span or div tags as Pandoc Span
      inlines or Div blocks.
    * `--trace` now works with the Markdown, HTML, Haddock, EPUB,
      Textile, and MediaWiki readers.  This is an option intended
      for debugging parsing problems; ordinary users should not need
      to use it.
    [behavior changes]
    * Changed behavior of the `markdown_attribute` extension, to bring
      it in line with PHP markdown extra and multimarkdown.  Setting
      `markdown="1"` on an outer tag affects all contained tags,
      recursively, until it is reversed with `markdown="0"` (#1378).
    * Revised markdown definition list syntax (#1429).  Both the reader
      and writer are affected.  This change brings pandoc's definition list
      syntax into alignment with that used in PHP markdown extra and
      multimarkdown (with the exception that pandoc is more flexible about
      the definition markers, allowing tildes as well as colons).  Lazily
      wrapped definitions are now allowed.  Blank space is required
      between list items.  The space before a definition is used to determine
      whether it is a paragraph or a "plain" element.  **WARNING: This change
      may break existing documents!**  Either check your documents for
      definition lists without blank space between items, or use
      `markdown+compact_definition_lists` for the old behavior.
    * `.numberLines` now works in fenced code blocks even if no language
      is given (#1287, jgm/highlighting-kate#40).
    * Improvements to `--filter`:
      + Don't search PATH for a filter with an explicit path.
      This fixed a bug wherein `--filter ./caps.py` would run `caps.py` from
      the system path, even if there was a `caps.py` in the working directory.
      + Respect shebang if filter is executable (#1389).
      + Don't print misleading error message.
      Previously pandoc would say that a filter was not found,
      even in a case where the filter had a syntax error.
    * HTML reader:
      + Parse `div` and `span` elements even without `--parse-raw`,
      provided `native_divs` and `native_spans` extensions are set.
      Motivation:  these now generate native pandoc Div and Span
      elements, not raw HTML.
      + Parse EPUB-specific elements if the `epub_html_exts`
      extension is enabled.  These include `switch`, `footnote`,
      `rearnote`, `noteref`.
    * Org reader:
      + Support for inline LaTeX.  Inline LaTeX is now accepted and parsed by the
      org-mode reader.  Both math symbols (like `\tau`) and LaTeX commands (like
      `\cite{Coffee}`), can be used without any further escaping (Albert
      Krewinkel).
    * Textile reader and writer:
      + The `raw_tex` extension is no longer set by default.  You can
      enable it with `textile+raw_tex`.
    * DocBook reader:
      + Support `equation`, `informalequation`, `inlineequation` elements with
      `mml:math` content.  This is converted into LaTeX and put into a Pandoc
      Math inline.
    * Revised `plain` output, largely following the style of Project
      Gutenberg:
      + Emphasis is rendered with `_underscores_`, strong emphasis
      with ALL CAPS.
      + Headings are rendered differently, with space to set them off,
      not with setext style underlines. Level 1 headers are ALL CAPS.
      + Math is rendered using unicode when possible, but without the
      distracting emphasis markers around variables.
      + Footnotes use a regular `[n]` style.
    * Markdown writer:
      + Horizontal rules are now a line across the whole page.
      + Prettier pipe tables.  Columns are now aligned  (#1323).
      + Respect the `raw_html` extension.  `pandoc -t markdown-raw_html`
      no longer emits any raw HTML, including span and div tags
      generated by Span and Div elements.
      + Use span with style for `SmallCaps` (#1360).
    * HTML writer:
      + Autolinks now have class `uri`, and email autolinks have class
      `email`, so they can be styled.
    * Docx writer:
      + Document formatting is carried over from `reference.docx`.
      This includes margins, page size, page orientation, header,
      and footer, including images in headers and footers.
      + Include abstract (if present) with `Abstract` style (#1451).
      + Include subtitle (if present) with `Subtitle` style, rather
      than tacking it on to the title (#1451).
    * Org writer:
      + Write empty span elements with an id attribute as org anchors.
      For example `Span ("uid",[],[]) []` becomes `<<uid>>`.
    * LaTeX writer:
      + Put table captions above tables, to match the conventional
      standard.  (Previously they appeared below tables.)
      + Use `\(..\)` instead of `$..$` for inline math (#1464).
      + Use `\nolinkurl` in email autolinks.  This allows them to be styled
      using `\urlstyle{tt}`.  Thanks to Ulrike Fischer for the solution.
      + Use `\textquotesingle` for `'` in inline code.  Otherwise we get
      curly quotes in the PDF output (#1364).
      + Use `\footnote<.>{..}` for notes in beamer, so that footnotes
      do not appear before the overlays in which their markers appear
      (#1525).
      + Don't produce a `\label{..}` for a Div or Span element.  Do produce
      a `\hyperdef{..}` (#1519).
    * EPUB writer:
      + If the metadata includes `page-progression-direction` (which can be
      `ltr` or `rtl`, the `page-progression-direction` attribute will
      be set in the EPUB spine (#1455).
    * Custom lua writers:
      + Custom writers now work with `--template`.
      + Removed HTML header scaffolding from `sample.lua`.
      + Made citation information available in lua writers.
    * `--normalize` and `Text.Pandoc.Shared.normalize` now consolidate
      adjacent `RawBlock`s when possible.
    [API changes]
    * Added `Text.Pandoc.Readers.Docx`, exporting `readDocx` (Jesse Rosenthal).
    * Added `Text.Pandoc.Readers.EPUB`, exporting `readEPUB` (Matthew
      Pickering).
    * Added `Text.Pandoc.Readers.Txt2Tags`, exporting `readTxt2Tags` (Matthew
      Pickering).
    * Added `Text.Pandoc.Writers.DokuWiki`, exporting `writeDokuWiki`
      (Clare Macrae).
    * Added `Text.Pandoc.Writers.Haddock`, exporting `writeHaddock`.
    * Added `Text.Pandoc.MediaBag`, exporting `MediaBag`, `lookupMedia`,
      `insertMedia`, `mediaDirectory`, `extractMediaBag`.  The docx and epub
      readers return a pair of a `Pandoc` document and a `MediaBag` with
      the media resources they contain.  This can be extracted using
      `--extract-media`.  Writers that incorporate media (PDF, Docx,
      ODT, EPUB, RTF, or HTML formats with `--self-contained`) will look
      for resources in the `MediaBag` generated by the reader, in addition to
      the file system or web.
    * `Text.Pandoc.Readers.TexMath`: Removed deprecated `readTeXMath`.
      Renamed `readTeXMath'` to `texMathToInlines`.
    * `Text.Pandoc`: Added `Reader` data type (Matthew Pickering).
      `readers` now associates names of readers with `Reader`
      structures.  This allows inclusion of readers, like the docx
      reader, that take binary rather than textual input.
    * `Text.Pandoc.Shared`:
      + Added `capitalize` (Artyom Kazak), and replaced uses of
      `map toUpper` (which give bad results for many languages).
      + Added `collapseFilePath`, which removes intermediate `.` and
      `..` from a path (Matthew Pickering).
      + Added `fetchItem'`, which works like `fetchItem` but searches
      a `MediaBag` before looking on the net or file system.
      + Added `withTempDir`.
      + Added `removeFormatting`.
      + Added `extractSpaces` (from HTML reader) and generalized its type
      so that it can be used by the docx reader (Matthew Pickering).
      + Added `ordNub`.
      + Added `normalizeInlines`, `normalizeBlocks`.
      + `normalize` is now `Pandoc -> Pandoc` instead of
      `Data a :: a -> a`.  Some users may need to change their uses of
      `normalize` to the newly exported `normalizeInlines` or
      `normalizeBlocks`.
    * `Text.Pandoc.Options`:
      + Added `writerMediaBag` to `WriterOptions`.
      + Removed deprecated and no longer used `readerStrict` in
      `ReaderOptions`.  This is handled by `readerExtensions` now.
      + Added `Ext_compact_definition_lists`.
      + Added `Ext_epub_html_exts`.
      + Added `Ext_native_divs` and `Ext_native_spans`.
      This allows users to turn off the default pandoc behavior of
      parsing contents of div and span tags in markdown and HTML
      as native pandoc Div blocks and Span inlines.
    * `Text.Pandoc.Parsing`:
      + Generalized `readWith` to `readWithM` (Matthew Pickering).
      + Export `runParserT` and `Stream` (Matthew Pickering).
      + Added `HasQuoteContext` type class (Matthew Pickering).
      + Generalized types of `mathInline`, `smartPunctuation`, `quoted`,
      `singleQuoted`, `doubleQuoted`, `failIfInQuoteContext`,
      `applyMacros` (Matthew Pickering).
      + Added custom `token` (Matthew Pickering).
      + Added `stateInHtmlBlock` to `ParserState`.  This is used to keep
      track of the ending tag we're waiting for when we're parsing inside
      HTML block tags.
      + Added `stateMarkdownAttribute` to `ParserState`. This is used
      to keep track of whether the markdown attribute has been set in
      an enclosing tag.
      + Generalized type of `registerHeader`, using new type classes
      `HasReaderOptions`, `HasIdentifierList`, `HasHeaderMap` (Matthew
      Pickering).  These allow certain common functions to be reused
      even in parsers that use custom state (instead of `ParserState`),
      such as the MediaWiki reader.
      + Moved `inlineMath`, `displayMath` from Markdown reader to Parsing,
      and generalized their types (Matthew Pickering).
    * `Text.Pandoc.Pretty`:
      + Added `nestle`.
      + Added `blanklines`, which guarantees a certain number of blank lines
      (and no more).
    [bug fixes]
    * Markdown reader:
      + Fixed parsing of indented code in list items.  Indented code
      at the beginning of a list item must be indented eight spaces
      from the margin (or edge of the container), or four spaces
      from the list marker, whichever is greater.
      + Fixed small bug in HTML parsing with `markdown_attribute`, which
      caused incorrect tag nesting for input like
      `<aside markdown="1">*hi*</aside>`.
      + Fixed regression with intraword underscores (#1121).
      + Improved parsing of inline links containing quote characters (#1534).
      + Slight rewrite of `enclosure`/`emphOrStrong` code.
      + Revamped raw HTML block parsing in markdown (#1330).
      We no longer include trailing spaces and newlines in the
      raw blocks.  We look for closing tags for elements (but without
      backtracking).  Each block-level tag is its own `RawBlock`;
      we no longer try to consolidate them (though `--normalize` will do so).
      + Combine consecutive latex environments.  This helps when you have
      two minipages which can't have blank lines between them (#690, #1196).
      + Support smallcaps through span.
      `<span style="font-variant:small-caps;">foo</span>` will be
      parsed as a `SmallCaps` inline, and will work in all output
      formats that support small caps (#1360).
      + Prevent spurious line breaks after list items (#1137).  When the
      `hard_line_breaks` option was specified, pandoc would formerly
      produce a spurious line break after a tight list item.
      + Fixed table parsing bug (#1333).
      + Handle `c++` and `objective-c` as language identifiers in
      github-style fenced blocks (#1318).
      + Inline math must have nonspace before final `$` (#1313).
    * LaTeX reader:
      + Handle comments at the end of tables.  This resolves the issue
      illustrated in <http://stackoverflow.com/questions/24009489>.
      + Correctly handle table rows with too few cells.  LaTeX seems to
      treat them as if they have empty cells at the end  (#241).
      + Handle leading/trailing spaces in `\emph` better.
      `\emph{ hi }` gets parsed as `[Space, Emph [Str "hi"], Space]`
      so that we don't get things like `* hi *` in markdown output.
      Also applies to `\textbf` and some other constructions (#1146).
      + Don't assume preamble doesn't contain environments (#1338).
      + Allow (and discard) optional argument for `\caption` (James Aspnes).
    * HTML reader:
      + Fixed major parsing problem with HTML tables.  Table cells were
      being combined into one cell (#1341).
      + Fixed performance issue with malformed HTML tables.
      We let a `</table>` tag close an open `<tr>` or `<td>` (#1167).
      + Allow space between `<col>` and `</col>`.
      + Added `audio` and `source` in `eitherBlockOrInline`.
      + Moved `video`, `svg`, `progress`, `script`, `noscript`, `svg` from
      `blockTags` to `eitherBlockOrInline`.
      + `map` and `object` were mistakenly in both lists; they have been removed
      from `blockTags`.
      + Ignore `DOCTYPE` and `xml` declarations.
    * MediaWiki reader:
      + Don't parse backslash escapes inside `<source>` (#1445).
      + Tightened up template parsing.
      The opening `{{` must be followed by an alphanumeric or `:`.
      This prevents the exponential slowdown in #1033.
      + Support "Bild" for images.
    * DocBook reader:
      + Better handle elements inside code environments.  Pandoc's document
      model does not allow structure inside code blocks, but at least this way
      we preserve the text (#1449).
      + Support `<?asciidoc-br?>` (#1236).
    * Textile reader:
      + Fixed list parsing. Lists can now start without an intervening
      blank line (#1513).
      + HTML block-level tags that do not start a line are parsed as
      inline HTML and do not interrupt paragraphs (as in RedCloth).
    * Org reader:
      + Make tildes create inline code (#1345).  Also relabeled `code` and
      `verbatim` parsers to accord with the org-mode manual.
      + Respect `:exports` header argument in code blocks (Craig Bosma).
      + Fixed tight lists with sublists (#1437).
    * EPUB writer:
      + Avoid excess whitespace in `nav.xhtml`.  This should improve
      TOC view in iBooks (#1392).
      + Fixed regression on cover image.
      In 1.12.4 and 1.12.4.2, the cover image would not appear properly,
      because the metadata id was not correct.  Now we derive the id from the
      actual cover image filename, which we preserve rather than using
      "cover-image."
      + Keep newlines between block elements.  This allows
      easier diff-ability (#1424).
      + Use `stringify` instead of custom `plainify`.
      + Use `renderTags'` for all tag rendering.  This properly handles tags
      that should be self-closing.  Previously `<hr/>` would appear in EPUB
      output as `<hr></hr>` (#1420).
      + Better handle HTML media tags.
      + Handle multiple dates with OPF `event` attributes.  Note: in EPUB3 we
      can have only one dc:date, so only the first one is used.
    * LaTeX writer:
      + Correctly handle figures in notes.  Notes can't contain figures in
      LaTeX, so we fake it to avoid an error  (#1053).
      + Fixed strikeout + highlighted code (#1294).
      Previously strikeout highlighted code caused an error.
    * ConTeXt writer:
      + Improved detection of autolinks with URLs containing escapes.
    * RTF writer:
      + Improved image embedding: `fetchItem'` is now used to get the
      images, and calculated image sizes are indicated in the RTF.
      + Avoid extra paragraph tags in metadata (#1421).
    * HTML writer:
      + Deactivate "incremental" inside slide speaker notes (#1394).
      + Don't include empty items in the table of contents for
      slide shows.  (These would result from creating a slide
      using a horizontal rule.)
    * MediaWiki writer:
      + Minor renaming of `st` prefixed names.
    * AsciiDoc writer:
      + Double up emphasis and strong emphasis markers in intraword
      contexts, as required by asciidoc (#1441).
    * Markdown writer:
      + Avoid wrapping that might start a list, blockquote, or header (#1013).
      + Use Span instead of (hackish) `SmallCaps` in `plainify`.
      + Don't use braced attributes for fenced code (#1416).
      If `Ext_fenced_code_attributes` is not set, the first class
      attribute will be printed after the opening fence as a bare word.
      + Separate adjacent lists of the same kind with an HTML comment (#1458).
    * PDF writer:
      + Fixed treatment of data uris for images (#1062).
    * Docx writer:
      + Use Compact style for empty table cells (#1353).
      Otherwise we get overly tall lines when there are empty
      table cells and the other cells are compact.
      + Create overrides per-image for `media/` in reference docx.
      This should be somewhat more robust and cover more types of images.
      + Improved `entryFromArchive` to avoid an unneeded parse.
      + Section numbering carries over from reference.docx (#1305).
      + Simplified `abstractNumId` numbering.  Instead of sequential numbering,
      we assign numbers based on the list marker styles.
    * `Text.Pandoc.Options`:
      + Removed `Ext_fenced_code_attributes` from `markdown_github`
      extensions.
    * `Text.Pandoc.ImageSize`:
      + Use default instead of failing if image size not found
      in exif header (#1358).
      + ignore unknown exif header tag rather than crashing.
      Some images seem to have tag type of 256, which was causing
      a runtime error.
    * `Text.Pandoc.Shared`:
      + `fetchItem`:  unescape URI encoding before reading local file (#1427).
      + `fetchItem`:  strip a fragment like `?#iefix` from the extension before
      doing mime lookup, to improve mime type guessing.
      + Improved logic of `fetchItem`:  absolute URIs are fetched from the net;
      other things are treated as relative URIs if `sourceURL` is `Just _`,
      otherwise as file paths on the local file system.
      + `fetchItem` now properly handles links without a protocol (#1477).
      + `fetchItem` now escapes characters not allowed in URIs before trying
      to parse the URIs.
      + Fixed runtime error with `compactify'DL` on certain lists (#1452).
    * `pandoc.hs`: Don't strip path off of `writerSourceURL`: the path is
      needed to resolve relative URLs when we fetch resources (#750).
    * `Text.Pandoc.Parsing`
      + Simplified `dash` and `ellipsis` (#1419).
      + Removed `(>>~)` in favor of the equivalent `(<*)` (Matthew Pickering).
      + Generalized functions to use `ParsecT` (Matthew Pickering).
      + Added `isbn` and `pmid` to list of recognized schemes (Matthew
      Pickering).
    [template changes]
    * Added haddock template.
    * EPUB3:  Added `type` attribute to `link` tags.  They are supposed to
      be "advisory" in HTML5, but kindlegen seems to require them.
    * EPUB3:  Put title page in section with `epub:type="titlepage"`.
    * LaTeX: Made `\subtitle` work properly (#1327).
    * LaTeX/Beamer: remove conditional around date (#1321).
    * LaTeX:  Added `lot` and `lof` variables, which can be set to
      get `\listoftables` and `\listoffigures` (#1407).  Note that
      these variables can be set at the command line with `-Vlot -Vlof`
      or in YAML metadata.
    [under the hood improvements]
    * Rewrote normalize for efficiency (#1385).
    * Rewrote Haddock reader to use `haddock-library` (#1346).
      + This brings pandoc's rendering of haddock markup in line
      with the new haddock.
      + Fixed line breaks in `@` code blocks.
      + alex and happy are no longer build-depends.
    * Added `Text.Pandoc.Compat.Directory` to allow building against
      different versions of the `directory` library.
    + Added `Text.Pandoc.Compat.Except` to allow building against
      different verions of `mtl`.
    * Code cleanup in some writers, using Reader monad to avoid
      passing options parameter around (Matej Kollar).
    * Improved readability in `pandoc.hs`.
    * Miscellaneous code cleanups (Artyom Kazak).
    * Avoid `import Prelude hiding (catch)` (#1309, thanks to Michael
      Thompson).
    * Changed `http-conduit` flag to `https`.  Depend on `http-client`
      and `http-client-tls` instead of `http-conduit`.  (Note:  pandoc still
      depends on `conduit` via `yaml`.)
    * Require `highlighting-kate >= 0.5.8.5` (#1271, #1317, Debian #753299).
      This change to highlighting-kate means that PHP fragments no longer need
      to start with `<?php`.  It also fixes a serious bug causing failures with
      ocaml and fsharp.
    * Require latest `texmath`.  This fixes `\tilde{E}` and allows
      `\left` to be used with `]`, `)` etc. (#1319), among many other
      improvements.
    * Require latest `zip-archive`.  This has fixes for unicode path names.
    * Added tests for plain writer.
    * `Text.Pandoc.Templates`:
      + Fail informatively on template syntax errors.
      With the move from parsec to attoparsec, we lost good error
      reporting.  In fact, since we weren't testing for end of input,
      malformed templates would fail silently.  Here we revert back to
      Parsec for better error messages.
      + Use `ordNub` (#1022).
    * Benchmarks:
      + Made benchmarks compile again (Artyom Kazak).
      + Fixed so that the failure of one benchmark does not prevent others
      from running (Artyom Kazak).
      + Use `nfIO` instead of the `getLength` trick to force full evaluation.
      + Changed benchmark to use only the test suite, so that benchmarks
      run more quickly.
    * Windows build script:
      + Use one install command for pandoc, pandoc-citeproc.
      + Force install of pandoc-citeproc.
    * `make_osx_package`:  Call zip file `pandoc-VERSION-osx.zip`.
      The zip should not be named `SOMETHING.pkg.zip`, or OSX finder
      will extract it into a folder named `SOMETHING.pkg`, which it
      will interpret as a defective package (#1308).
    * `README`:
      + Made headers for all extensions so they have IDs and can be
      linked to (Beni Cherniavsky-Paskin).
      + Fixed typos (Phillip Alday).
      + Fixed documentation of attributes (#1315).
      + Clarified documentation on small caps (#1360).
      + Better documentation for `fenced_code_attributes` extension
      (Caleb McDaniel).
      + Documented fact that you can put YAML metadata in a separate file
      (#1412).
    pandoc (1.12.4.2)
    =================
    * Shared:  `addMetaValue` now behaves slightly differently:
      if both the new and old values are lists, it concatenates their
      contents to form a new list.
    * LaTeX reader:
      + Set `bibliography` in metadata from `\bibliography` or
      `\addbibresource` command.
      + Don't error on `%foo` with no trailing newline.
    * Org reader:
      + Support code block headers (`#+BEGIN_SRC ...`) (Albert Krewinkel).
      + Fix parsing of blank lines within blocks (Albert Krewinkel).
      + Support pandoc citation extension (Albert Krewinkel).  This can
      be turned off by specifying `org-citations` as the input format.
    * Markdown reader:
      + `citeKey` moved to `Text.Pandoc.Parsing` so it can be used by
      other readers (Albert Krewinkel).
    * `Text.Pandoc.Parsing`:
      + Added `citeKey` (see above).
      + Added `HasLastStrPosition` type class and `updateLastStrPos`
      and `notAfterString` functions.
    * Updated copyright notices (Albert Krewinkel).
    * Added default.icml to data files so it installs with the package.
    pandoc (1.12.4)
    ===============
    * Made it possible to run filters that aren't executable (#1096).
      Pandoc first tries to find the executable (searching the path
      if path isn't given).  If it fails, but the file exists and has
      a `.py`, `.pl`, `.rb`, `.hs`, or `.php` extension, pandoc runs the filter
      using the appropriate interpreter.  This should make it easier to
      use filters on Windows, and make it more convenient for everyone.
    * Added Emacs org-mode reader (Albert Krewinkel).
    * Added InDesign ICML Writer (mb21).
    * MediaWiki reader:
      + Accept image links in more languages (Jaime Marquínez Ferrándiz).
      + Fixed bug in certain nested lists (#1213).  If a level 2 list was
      followed by a level 1 list, the first item of the level 1 list
      would be lost.
      + Handle table rows containing just an HTML comment (#1230).
    * LaTeX reader:
      + Give better location information on errors, pointing to line
      numbers within included files (#1274).
      + LaTeX reader:  Better handling of `table` environment (#1204).
      Positioning options no longer rendered verbatim.
      + Better handling of figure and table with caption (#1204).
      + Handle `@{}` and `p{length}` in tabular.  The length is not actually
      recorded, but at least we get a table (#1180).
      + Properly handle `\nocite`.  It now adds a `nocite` metadata
      field.  Citations there will appear in the bibliography but not
      in the text (unless you explicitly put a `$nocite$` variable
      in your template).
    * Markdown reader:
      + Ensure that whole numbers in YAML metadata are rendered without
      decimal points.  (This became necessary with changes to aeson
      and yaml libraries.  aeson >= 0.7 and yaml >= 0.8.8.2 are now required.)
      + Fixed regression on line breaks in strict mode (#1203).
      + Small efficiency improvements.
      + Improved parsing of nested `div`s.  Formerly a closing `div` tag
      would be missed if it came right after other block-level tags.
      + Avoid backtracking when closing `</div>` not found.
      + Fixed bug in reference link parsing in `markdown_mmd`.
      + Fixed a bug in list parsing (#1154).  When reading a raw list
      item, we now strip off up to 4 spaces.
      + Fixed parsing of empty reference link definitions (#1186).
      + Made one-column pipe tables work (#1218).
    * Textile reader:
      + Better support for attributes.  Instead of being ignored, attributes
      are now parsed and included in Span inlines.  The output will be a bit
      different from stock textile: e.g. for `*(foo)hi*`, we'll get
      `<em><span class="foo">hi</span></em>` instead of
      `<em class="foo">hi</em>`.  But at least the data is not lost.
      + Improved treatment of HTML spans (%) (#1115).
      + Improved link parsing.  In particular we now pick up on attributes.
      Since pandoc links can't have attributes, we enclose the whole link in
      a span if there are attributes (#1008).
      + Implemented correct parsing rules for inline markup (#1175, Matthew
      Pickering).
      + Use Builder (Matthew Pickering).
      + Fixed list parsing bug (#1500).
      + Don't allow inline formatting to extend over newlines.
      This matches the behavior of RedCarpet, avoids some ugly bugs,
      and improves performance.
    * DocBook reader:
      + Better treatment of `formalpara`.  We now emit the title (if present)
      as a separate paragraph with boldface text (#1215).
      + Set metadata `author` not `authors`.
      + Added recognition of `authorgroup` and `releaseinfo` elements (#1214,
      Matthew Pickering).
      + Converted current meta information parsing in DocBook to a more
      extensible version which is aware of the more recent meta
      representation (Matthew Pickering).
    * HTML reader:
      + Require tagsoup 0.13.1, to fix a bug with parsing of script tags
      (#1248).
      + Treat processing instructions & declarations as block.  Previously
      these were treated as inline, and included in paragraph tags in HTML
      or DocBook output, which is generally not what is wanted (#1233).
      + Updated `closes` with rules from HTML5 spec.
      + Use Builder (Matthew Pickering, #1162).
    * RST reader:
      + Remove duplicate `http` in PEP links (Albert Krewinkel).
      + Make rst figures true figures (#1168, CasperVector)
      + Enhanced Pandoc's support for rST roles (Merijn Verstaaten).
      rST parser now supports: all built-in rST roles, new role definition,
      role inheritance, though with some limitations.
      + Use `author` rather than `authors` in metadata.
      + Better handling of directives.  We now correctly handle field
      lists that are indented more than three spaces.  We treat an
      `aafig` directive as a code block with attributes, so it can be
      processed in a filter (#1212).
    * LaTeX writer:
      + Mark span contents with label if span has an ID (Albert Krewinkel).
      + Made `--toc-depth` work well with books in latex/pdf output (#1210).
      + Handle line breaks in simple table cells (#1217).
      + Workaround for level 4-5 headers in quotes.  These previously produced
      invalid LaTeX: `\paragraph` or `\subparagraph` in a `quote` environment.
      This adds an `mbox{}` in these contexts to work around the problem.
      See <http://tex.stackexchange.com/a/169833/22451> (#1221).
      + Use `\/` to avoid en-dash ligature instead of `-{}-` (Vaclav Zeman).
      This is to fix LuaLaTeX output. The `-{}-` sequence does not avoid the
      ligature with LuaLaTeX but `\/` does.
      + Fixed string escaping in `hyperref` and `hyperdef` (#1130).
    * ConTeXt writer:  Improved autolinks (#1270).
    * DocBook writer:
      + Improve handling of hard line breaks in Docbook writer
      (Neil Mayhew).  Use a `<literallayout>` for the entire paragraph, not
      just for the newline character.
      + Don't let line breaks inside footnotes influence the enclosing
      paragraph (Neil Mayhew).
      + Distinguish tight and loose lists in DocBook output, using
      `spacing="compact"` (Neil Mayhew, #1250).
    * Docx writer:  When needed files are not present in the user's
      `reference.docx`, fall back on the versions in the `reference.docx`
      in pandoc's data files. This fixes a bug that occurs when a
      `reference.docx` saved by LibreOffice is used. (#1185)
    * EPUB writer:
      + Include extension in epub ids.  This fixes a problem with duplicate
      extensions for fonts and images with the same base name but different
      extensions (#1254).
      + Handle files linked in raw `img` tags (#1170).
      + Handle media in `audio` source tags (#1170).
      Note that we now use a `media` directory rather than `images`.
      + Incorporate files linked in `video` tags (#1170).  `src` and `poster`
      will both be incorporated into `content.opf` and the epub container.
    * HTML writer:
      + Add colgroup around col tags (#877).  Also affects EPUB writer.
      + Fixed bug with unnumbered section headings.  Unnumbered section
      headings (with class `unnumbered`) were getting numbers.
      + Improved detection of image links. Previously image links with
      queries were not recognized, causing `<embed>` to be used instead
      of `<img>`.
    * Man writer:  Ensure that terms in definition lists aren't line wrapped
      (#1195).
    * Markdown writer:
      + Use proper escapes to avoid unwanted lists (#980).  Previously we used
      0-width spaces, an ugly hack.
      + Use longer backtick fences if needed (#1206).  If the content contains a
      backtick fence and there are attributes, make sure longer fences are
      used to delimit the code.  Note:  This works well in pandoc, but github
      markdown is more limited, and will interpret the first string of three
      or more backticks as ending the code block.
    * RST writer:  Avoid stack overflow with certain tables (#1197).
    * RTF writer:  Fixed table cells containing paragraphs.
    * Custom writer:
      + Correctly handle UTF-8 in custom lua scripts (#1189).
      + Fix bugs with lua scripts with mixed-case filenames and
      paths containing `+` or `-` (#1267).  Note that `getWriter`
      in `Text.Pandoc` no longer returns a custom writer on input
      `foo.lua`.
    * AsciiDoc writer:  Handle multiblock and empty table cells
      (#1245, #1246).  Added tests.
    * `Text.Pandoc.Options`: Added `readerTrace` to `ReaderOptions`
    * `Text.Pandoc.Shared`:
      + Added `compactify'DL` (formerly in markdown reader) (Albert Krewinkel).
      + Fixed bug in `toRomanNumeral`:  numbers ending with '9' would
      be rendered as Roman numerals ending with 'IXIV' (#1249).  Thanks to
      Jesse Rosenthal.
      + `openURL`: set proxy with value of http_proxy env variable (#1211).
      Note:  proxies with non-root paths are not supported, due to
      limitations in `http-conduit`.
    * `Text.Pandoc.PDF`:
      + Ensure that temp directories deleted on Windows (#1192).  The PDF is
      now read as a strict bytestring, ensuring that process ownership will
      be terminated, so the temp directory can be deleted.
      + Use `/` as path separators in a few places, even on Windows.
      This seems to be necessary for texlive (#1151, thanks to Tim Lin).
      + Use `;` for `TEXINPUTS` separator on Windows (#1151).
      + Changes to error reporting, to handle non-UTF8 error output.
    * `Text.Pandoc.Templates`:
      + Removed unneeded datatype context (Merijn Verstraaten).
      + YAML objects resolve to "true" in conditionals (#1133).
      Note:  If `address` is a YAML object and you just have `$address$`
      in your template, the word `true` will appear, which may be
      unexpected.  (Previously nothing would appear.)
    * `Text.Pandoc.SelfContained`:
      + `mkSelfContained` now takes just two arguments, `WriterOptions` and
      the string.
    * It no longer looks in data files.  This only made sense when we
      had copies of slidy and S5 code there.
    * `fetchItem'` is used instead of the nearly duplicate `getItem`.
      + Handle `poster` attribute in `video` tags (#1188).
    * `Text.Pandoc.Parsing`:
      + Made `F` an instance of Applicative (#1138).
      + Added `stateCaption`.
      + Added `HasMacros`, simplified other typeclasses.
      Removed `updateHeaderMap`, `setHeaderMap`, `getHeaderMap`,
      `updateIdentifierList`, `setIdentifierList`, `getIdentifierList`.
      + Changed the smart punctuation parser to return `Inlines`
      rather than `Inline` (Matthew Pickering).
      + Changed `HasReaderOptions`, `HasHeaderMap`, `HasIdentifierList`
      from typeclasses of monads to typeclasses of states.  This simplifies
      the instance definitions and provides more flexibility.  Generalized
      type of `getOption` and added a default definition.  Removed
      `askReaderOption`.  Added `extractReaderOption`.  Added
      `extractHeaderMap` and `updateHeaderMap` in `HasHeaderMap`.
      Gave default definitions for `getHeaderMap`, `putHeaderMap`,
      `modifyHeaderMap`.  Added `extractIdentifierList` and
      `updateIdentifierList` in `HasIdentifierList`.  Gave defaults
      for `getIdentifierList`, `putIdentifierList`, and
      `modifyIdentifierList`.  The ultimate goal here is to allow different
      parsers to use their own, tailored parser states (instead of
      `ParserState`) while still using shared functions.
    * Template changes:
      + LaTeX template: Use `fontenc` package only with `pdflatex` (#1164).
      + LaTeX template:  Add `linestretch` and `fontfamily` variables.
      + LaTeX template:  Conditionalize author and date commands.
      + Beamer template: Consistent styles for figure and table captions
      (aaronwolen).
      + LaTeX and beamer template:  Adjust widths correctly for oversized
      images.  Use `\setkeys{Gin}{}` to set appropriate defaults for
      `\includegraphics` (Yihui Xie, Garrick Aden-Buie).  Load
      `upquote` only after `fontenc` (Yihui Xie).
      + Beamer template: Added caption package (#1200).
      + Beamer template:  changes for better unicode handling (KarolS).
      + DocBook template:  use `authorgroup` if there are authors.
      + revealjs template: Move `include-after` to end (certainlyakey).
      + revealjs template: Fixed PDF print function (#1220, kevinkenan).
    * Bumped version bounds of dependencies.
    * Added a `--trace` command line option, for debugging backtracking
      bugs.  So far this only works with the markdown reader.
    * MathMLinHTML:  Fixed deprecation warning (#362, gwern, Albert Krewinkel).
    * Updated travis script to test with multiple GHC versions.
    * Force failure of a Travis build if GHC produces warnings (Albert
      Krewinkel).
    * Add `.editorconfig` (Albert Krewinkel).
      See <http://editorconfig.org/> for details.
    * Give more useful error message if '-t pdf' is specified (#1155).
    * Added `Cite`, `SmallCaps` to `Arbitrary` instance (#1269).
    * Allow `html4` as a synonym of `html` as a reader (it already works
      as a writer).
    * README:
      + Added an explanation of how to use YAML metadata to
      force items to appear in the bibliography without citations in
      the text (like LaTeX `\nocite`).
      + Added note to `--bibtex/--natbib`: not for use in making PDF
      (#1194, thanks to nahoj).
      + Added explanatory notes about `--natbib` and `--biblatex`.
      + Added specification of legal syntax for citation keys.
      + Fixed variable defaults documentation (Albert Krewinkel).
    * Removed copyright statements for files that have been removed
      (Albert Krewinkel).
    * Moved some doc files from `data-files` to `extra-source-files` (#1123).
      They aren't needed at runtime.  We keep README and COPYRIGHT in data
      to ensure that they'll be available on all systems on which pandoc
      is installed.
