BSD-2-Clause AND BSD-3-Clause AND MIT
* Wed Dec 04 2024 Martin Pluskal <[email protected]>
- Update to version 1.25.2:
* Support wasm32 by disabling ZLIB WITH_OPTIM option.
* Avoid rip-relative addressing for OSX x86_64.
* Added support for nvcc (NVidia Cuda Compiler) in CMake.
* Fix public include directories for blosc2 targets.
* Fix ub in shuffle and unshuffle by marking _dst non-const.
- See RELEASE_NOTES.md for detailed list of changes from previous
releases
* Fri Apr 26 2024 Ben Greiner <[email protected]>
- Update to 2.14.4
* Bumped SONAME due to recent API changes. See #581.
- Release 2.14.3
* More fixes for internal fuzzer.
- Release 2.14.2
* Fixes for CVE-2024-3203 and CVE-2024-3204.
- Release 2.14.1
* When loading plugins, first try with python and then python3.
This is because many linux distros do not have python as a
symlink to python3 anymore.
- Release 2.14.0
* Fixed a bug preventing buffers to be appended to empty
(0-sized) b2nd arrays.
* New acceleration path for b2nd_append(). This new path is much
faster (up to 4x) than the previous one, specially for large
arrays. See bench/bench_stack_append.c for a benchmark.
* New examples for using the b2nd_set_slice_cbuffer() and
b2nd_append() functions for adding data into existing b2nd
arrays. See examples/example_stack_images.c.
* Now, python3 is used for finding plugins instead of python.
This is because many linux distros do not have python as a
symlink to python3 anymore.
* New round of fixing warnings. Now, C-Blosc2 should be
relatively free of them.
* Small performance tweak for clevel 1 in BloscLZ codec.
* Fixed a leak in frame code. Closes #591. Thanks to
@LuMingYinDetect.
* Disable shuffle repeat in filters pipeline. This was broken
since the initial implemented, and it was never documented.
Also, compression ratios do not seem to be improved in our
experiments, so this capability has been removed completely.
* Support for new Intel compilers (2023.0.1 and on). Fixes #533.
Thanks to Nick Papior.
* Fri Mar 22 2024 Ben Greiner <[email protected]>
- Update to 2.13.2
* Better checking for SSSE3 availability in Visual Studio.
Probably fixes #546 too. Thanks to @t20100 (Thomas Vincent) for
the PR (#586).
* Documented the globally registered filters and codecs. See:
https://www.blosc.org/c-blosc2/reference/utility_variables.html#codes-for-filters
https://www.blosc.org/c-blosc2/reference/utility_variables.html#compressor-codecs
- Reenable previously failing but never acknowledged test
* gh#Blosc/c-blosc2#464
* Wed Feb 07 2024 Ben Greiner <[email protected]>
- Update to 2.13.1
* Removed private include in b2nd.h. This fixes issue #579.
- Release 2.13.0
* Added a new BLOSC_FILTER_INT_TRUNC filter for truncating
integers to a given number of bits. This is useful for
compressing integers that are not using all the bits of the
type. See PR #577.
* Optimized zstd, specially when using dicts. See PR #578.
Initialize grok library when loading the plugin. This is
needed for other plugins to be able to use it without the need
of importing the package.
- Release 2.12.0
* New blosc2_get_slice_nchunks function for getting the
unidimensional chunk indexes of a Blosc2 container slice.
* Globally registered new codec grok. This will be loaded
dynamically.
* Fri Dec 01 2023 Ben Greiner <[email protected]>
- Update to 2.11.3
* Frames accept now typesizes that are larger than 255 (and up to
2**31). See PyTables/PyTables#1086. Thanks to @chris-allan for
the report.
* AVX512 runtime dispatching has been fixed (basically disabled)
for GCC versions <= 10.
* Use typedef for blosc_timestamp_t. Thanks to Magnus Ulimoen.
* Thu Nov 30 2023 Steve Kowalik <[email protected]>
- Update to 2.11.2:
* Added support for ARMv7l platforms (Raspberry Pi). The NEON version
of the bitshuffle filter was not compiling there, and besides it
offered no performance advantage over the generic bitshuffle version
(it is 2x to 3x slower actually). So bitshuffle-neon.c has been
disabled by default in all ARM platforms.
* Also, unaligned access has been disabled in all ARM non-64bits platforms.
It turned out that, at least the armv7l CPU in Raspberry Pi 4, had
issues because __ARM_FEATURE_UNALIGNED C macro was asserted in the
compiler (both gcc and clang), but it actually made binaries to raise
a "Bus error".
* Thanks to Ben Nuttall for providing a Raspberry Pi for tracking down
these issues.
- Release 2.11.1
* Fix ALTIVEC header. Only affects to IBM POWER builds. Thanks to
Michael Kuhn for providing a patch.
- Release 2.11.0
* New AVX512 support for the bitshuffle filter. This is a backport of
the upstream bitshuffle project. Expect up to 20% better compression
speed on AMD Zen4 architecture (7950X3D CPU).
* Add c-blosc2 package definition for Guix. Thanks to Ivan Vilata.
* Properly check calls to strtol. Fixes #558.
* Export the b2nd_copy_buffer function. This may be useful for other
projects dealing with multidimensional arrays in memory. Thanks to
Ivan Vilata.
* Better check that nthreads must be >= 1 and <= INT16_MAX. Fixes #559.
* Fix compile arguments for armv7l. Thanks to Ben Greiner.
- Drop patch c-blosc2-pr563-armv7l-option.patch, included upstream.
* Sat Oct 14 2023 Ben Greiner <[email protected]>
- Update to 2.10.5
* Fix a variable name in a test that was causing a segfault in
some platforms.
* Change tuner's functions signature to return always an error
code. This allows for better error checking when using plugable
tuners in Blosc2.
* Do checks when creating contexts.
- Release 2.10.4
* Remove duplicated tune initialization since it is already done
in blosc2_create_cctx. Thanks to Marta Iborra
* Typos fixed. Thanks to Dimitri Papadopoulos.
- Release 2.10.3
* Globally registered new codec openhtj2k. This will be loaded
dynamically. See PR #557.
* Added a BLOSC_INFO macro for details on compression params.
* Added get_blocksize.c example on automatic blocksizes.
* Warning fixes.
- Add c-blosc2-pr563-armv7l-option.patch gh#Blosc/c-blosc2#563
(But there is sitll a "Bus error" in the CTests)
* Tue Aug 22 2023 Ben Greiner <[email protected]>
- Update to 2.10.2
* Several fixes for the CMake system. Thanks to Axel Huebl. See
PR #541 and #542.
- Changes from 2.10.0 to 2.10.1
* blosc2_remove_urlpath(const char *urlpath) does not return an
error when path does not exist.
* Changes in CMake installer to conserve targets and properties
on install, so CMake users do not need to write
FindBlosc2.cmake files anymore. This also helps to preserve
transitive dependencies on CMake targets, especially useful for
fully static builds, e.g., for Python wheels. Thanks to @ax3l
(Axel Huebl). See PR #537.
* Fix new typos. Thanks to @DimitriPapadopoulos. See PR #538.
- Changes from 2.9.3 to 2.10.0
* bytedelta filter has been fixed. For backward compatibility,
the old bytedelta filter is still available as
BLOSC_FILTER_BYTEDELTA_BUGGY symbol, with the same ID (34) than
before. The new, fixed bytedelta filter has received a new ID
(35) and it can be used via the usual BLOSC_FILTER_BYTEDELTA
symbol. That means that old data written with the buggy
bytedelta filter should be decompressed without issues. Thanks
to @foody (Tom Birch) for the fix. See #531, #532 for more
info.
* Filter buffers are correctly cycled now. Now it is possible to
use e.g. shuffle and bitshuffle filters in the pipeline. Thanks
to @foody (Tom Birch) for the fix. See #528 and PR #530.
* Assorted fixes for allowing better inclusion in external
projects. Thanks to @ax3l (Axel Huebel). See #525, #527 and
[#529].
- Changes from 2.9.2 to 2.9.3
* Thanks to Dimitri Papadopoulos for an extensive set of
improvements in documentation and code.
* load_lib is now a private function. Before was public, but
never meant to be.
* Several fixes for bugs discovered by the fuzzer.
- Changes from 2.9.1 to 2.9.2
* Now is possible to register the same plugin (as long as they
have the same ID and name) without errors. This is useful for
registering the same plugin without worrying on whether it has
been registered already.
* Improved detection of dynamic plugin locations. Now they must
implement plugin_module.print_libpath() as the canonical way to
find the path for the dynamic library plugin.
* The blosc2_static has gained the cmake
POSITION_INDEPENDENT_CODE property. This should allow to use
the static library in more situations.
* BLOSC_STUNE is defined in blosc2.h now. Fixes #481. Thanks to
@DimitriPapadopoulos.
* Fixed an issue when having incompressible data in combination
with lazy_chunks.
* Fix linking with static -DBUILD_STATIC=0. Fixes #480.
* Many small fixes and code improvements. Thanks to
@DimitriPapadopoulos, @bnavigator.

- Update to 2.9.1
* Allow the use of BTUNE by detecting the ``BTUNE_BALANCE``
environment variable.
- Release 2.9.0
* Dynamic plugins as Python wheels are supported now! This new
feature allows for creating plugins in C, distribute them as
wheels, and load them dynamically in runtime. Small example at
https://github.com/Blosc/blosc2_plugin_example
* BloscLZ can achieve more speed in clevel 1 now.
* Internal Zstd sources updated to latest 1.5.5 version.

- Add _constraints
* Thu Mar 30 2023 Andrea Manzini <[email protected]>
- Update to 2.8.0
* New bytedelta filter added. SIMD support for Intel and ARM platforms is there.
We have blogged about this: https://www.blosc.org/posts/bytedelta-enhance-compression-toolset
Thanks to Aras Pranckevičius for inspiration and initial implementation.
* Minor improvements in BloscLZ, leading to better compression ratios in general.
* BLoscLZ version bumped to 2.5.2.
* Updated internal zlib-ng to 2.0.7.

* Fri Feb 24 2023 Ben Greiner <[email protected]>
- Update to 2.7.1
* Caterva has been merged and carefully integrated in C-Blosc2 in
the new b2nd interface. For more info on the new interface, see
https://www.blosc.org/c-blosc2/reference/b2nd.html. Thanks to
Marta Iborra, Oscar Guiñón, J. David Ibáñez and Francesc Alted.
Also thanks to Aleix Alcacer for his great work in the Caterva
project. We have a blog about this:
https://www.blosc.org/posts/blosc2-ndim-intro
* Updated internal zstd sources to 1.5.4. Thanks to Dimitri
Papadopoulos.
* blosc2_schunk_avoid_cframe_free and blosc2_schunk_append_file
are exported as public functions now. Thanks to @bnavigator.
* BloscLZ codec is now treated exactly the same as LZ4. Before
BloscLZ was considered less capable of reaching decent
compression ratios, but this has changed quite a bit lately, so
there is no point in treating both differently.
* Fixed some leaks, mainly on the test suite.
* Fixed quite a bit of compiler warnings.
