    * Go upstream merged branch dev.boringcrypto in go1.19+.
    * In go1.x enable BoringCrypto via GOEXPERIMENT=boringcrypto.
    * In go1.x-openssl enable FIPS mode (or boring mode as the
      package is named) either via an environment variable
      GOLANG_FIPS=1 or by virtue of booting the host in FIPS mode.
    * When the operating system is operating in FIPS mode, Go
      applications which import crypto/tls/fipsonly limit operations
      to the FIPS ciphersuite.
    * go1.x-openssl is delivered as two large patches to go1.x
      applying necessary modifications from the golang-fips/go GitHub
      project for the Go crypto library to use OpenSSL as the
      external cryptographic library in a FIPS compliant way.
    * go1.x-openssl modifies the crypto/* packages to use OpenSSL for
      cryptographic operations.
    * go1.x-openssl uses dlopen() to call into OpenSSL.
    * SUSE RPM packaging introduces a fourth version digit go1.x.y.z
      corresponding to the golang-fips/go patchset tagged revision.

  - go1.21 (released 2023-08-08) is a major release of Go.
    go1.21.x minor releases will be provided through August 2024.
    https://github.com/golang/go/wiki/Go-Release-Cycle
    go1.21 arrives six months after go1.20. Most of its changes are
    in the implementation of the toolchain, runtime, and libraries.
    As always, the release maintains the Go 1 promise of
    compatibility. We expect almost all Go programs to continue to
    compile and run as before.
    Refs boo#1212475 go1.21 release tracking
    * Go 1.21 introduces a small change to the numbering of
      releases. In the past, we used Go 1.N to refer to both the
      overall Go language version and release family as well as the
      first release in that family. Starting in Go 1.21, the first
      release is now Go 1.N.0. Today we are releasing both the Go
      1.21 language and its initial implementation, the Go 1.21.0
      release. These notes refer to "Go 1.21"; tools like go version
      will report "go1.21.0" (until you upgrade to Go 1.21.1). See
      "Go versions" in the "Go Toolchains" documentation for details
      about the new version numbering.
    * Language change: Go 1.21 adds three new built-ins to the
      language.
    * Language change: The new functions min and max compute the
      smallest (or largest, for max) value of a fixed number of given
      arguments. See the language spec for details.
    * Language change: The new function clear deletes all elements
      from a map or zeroes all elements of a slice. See the language
      spec for details.
    * Package initialization order is now specified more
      precisely. This may change the behavior of some programs that
      rely on a specific initialization ordering that was not
      expressed by explicit imports. The behavior of such programs
      was not well defined by the spec in past releases. The new rule
      provides an unambiguous definition.
    * Multiple improvements that increase the power and precision of
      type inference have been made.
    * A (possibly partially instantiated generic) function may now be
      called with arguments that are themselves (possibly partially
      instantiated) generic functions.
    * Type inference now also considers methods when a value is
      assigned to an interface: type arguments for type parameters
      used in method signatures may be inferred from the
      corresponding parameter types of matching methods.
    * Similarly, since a type argument must implement all the methods
      of its corresponding constraint, the methods of the type
      argument and constraint are matched which may lead to the
      inference of additional type arguments.
    * If multiple untyped constant arguments of different kinds (such
      as an untyped int and an untyped floating-point constant) are
      passed to parameters with the same (not otherwise specified)
      type parameter type, instead of an error, now type inference
      determines the type using the same approach as an operator with
      untyped constant operands. This change brings the types
      inferred from untyped constant arguments in line with the types
      of constant expressions.
    * Type inference is now precise when matching corresponding types
      in assignments
    * The description of type inference in the language spec has been
      clarified.
    * Go 1.21 includes a preview of a language change we are
      considering for a future version of Go: making for loop
      variables per-iteration instead of per-loop, to avoid
      accidental sharing bugs. For details about how to try that
      language change, see the LoopvarExperiment wiki page.
    * Go 1.21 now defines that if a goroutine is panicking and
      recover was called directly by a deferred function, the return
      value of recover is guaranteed not to be nil. To ensure this,
      calling panic with a nil interface value (or an untyped nil)
      causes a run-time panic of type *runtime.PanicNilError.
      To support programs written for older versions of Go, nil
      panics can be re-enabled by setting GODEBUG=panicnil=1. This
      setting is enabled automatically when compiling a program whose
      main package is in a module with that declares go 1.20 or
      earlier.
    * Go 1.21 adds improved support for backwards compatibility and
      forwards compatibility in the Go toolchain.
    * To improve backwards compatibility, Go 1.21 formalizes Go's use
      of the GODEBUG environment variable to control the default
      behavior for changes that are non-breaking according to the
      compatibility policy but nonetheless may cause existing
      programs to break. (For example, programs that depend on buggy
      behavior may break when a bug is fixed, but bug fixes are not
      considered breaking changes.) When Go must make this kind of
      behavior change, it now chooses between the old and new
      behavior based on the go line in the workspace's go.work file
      or else the main module's go.mod file. Upgrading to a new Go
      toolchain but leaving the go line set to its original (older)
      Go version preserves the behavior of the older toolchain. With
      this compatibility support, the latest Go toolchain should
      always be the best, most secure, implementation of an older
      version of Go. See "Go, Backwards Compatibility, and GODEBUG"
      for details.
    * To improve forwards compatibility, Go 1.21 now reads the go
      line in a go.work or go.mod file as a strict minimum
      requirement: go 1.21.0 means that the workspace or module
      cannot be used with Go 1.20 or with Go 1.21rc1. This allows
      projects that depend on fixes made in later versions of Go to
      ensure that they are not used with earlier versions. It also
      gives better error reporting for projects that make use of new
      Go features: when the problem is that a newer Go version is
      needed, that problem is reported clearly, instead of attempting
      to build the code and instead printing errors about unresolved
      imports or syntax errors.
    * To make these new stricter version requirements easier to
      manage, the go command can now invoke not just the toolchain
      bundled in its own release but also other Go toolchain versions
      found in the PATH or downloaded on demand. If a go.mod or
      go.work go line declares a minimum requirement on a newer
      version of Go, the go command will find and run that version
      automatically. The new toolchain directive sets a suggested
      minimum toolchain to use, which may be newer than the strict go
      minimum. See "Go Toolchains" for details.
    * go command: The -pgo build flag now defaults to -pgo=auto, and
      the restriction of specifying a single main package on the
      command line is now removed. If a file named default.pgo is
      present in the main package's directory, the go command will
      use it to enable profile-guided optimization for building the
      corresponding program.
    * go command: The -C dir flag must now be the first flag on the
      command-line when used.
    * go command: The new go test option -fullpath prints full path
      names in test log messages, rather than just base names.
    * go command: The go test -c flag now supports writing test
      binaries for multiple packages, each to pkg.test where pkg is
      the package name. It is an error if more than one test package
      being compiled has a given package name.]
    * go command: The go test -o flag now accepts a directory
      argument, in which case test binaries are written to that
      directory instead of the current directory.
    * cgo: In files that import "C", the Go toolchain now correctly
      reports errors for attempts to declare Go methods on C types.
    * runtime: When printing very deep stacks, the runtime now prints
      the first 50 (innermost) frames followed by the bottom 50
      (outermost) frames, rather than just printing the first 100
      frames. This makes it easier to see how deeply recursive stacks
      started, and is especially valuable for debugging stack
      overflows.
    * runtime: On Linux platforms that support transparent huge
      pages, the Go runtime now manages which parts of the heap may
      be backed by huge pages more explicitly. This leads to better
      utilization of memory: small heaps should see less memory used
      (up to 50% in pathological cases) while large heaps should see
      fewer broken huge pages for dense parts of the heap, improving
      CPU usage and latency by up to 1%.
    * runtime: As a result of runtime-internal garbage collection
      tuning, applications may see up to a 40% reduction in
      application tail latency and a small decrease in memory
      use. Some applications may also observe a small loss in
      throughput. The memory use decrease should be proportional to
      the loss in throughput, such that the previous release's
      throughput/memory tradeoff may be recovered (with little change
      to latency) by increasing GOGC and/or GOMEMLIMIT slightly.
    * runtime: Calls from C to Go on threads created in C require
      some setup to prepare for Go execution. On Unix platforms, this
      setup is now preserved across multiple calls from the same
      thread. This significantly reduces the overhead of subsequent C
      to Go calls from ~1-3 microseconds per call to ~100-200
      nanoseconds per call.
    * compiler: Profile-guide optimization (PGO), added as a preview
      in Go 1.20, is now ready for general use. PGO enables
      additional optimizations on code identified as hot by profiles
      of production workloads. As mentioned in the Go command
      section, PGO is enabled by default for binaries that contain a
      default.pgo profile in the main package directory. Performance
      improvements vary depending on application behavior, with most
      programs from a representative set of Go programs seeing
      between 2 and 7% improvement from enabling PGO. See the PGO
      user guide for detailed documentation.
    * compiler: PGO builds can now devirtualize some interface method
      calls, adding a concrete call to the most common callee. This
      enables further optimization, such as inlining the callee.
    * compiler: Go 1.21 improves build speed by up to 6%, largely
      thanks to building the compiler itself with PGO.
    * assembler: On amd64, frameless nosplit assembly functions are
      no longer automatically marked as NOFRAME. Instead, the NOFRAME
      attribute must be explicitly specified if desired, which is
      already the behavior on other architectures supporting frame
      pointers. With this, the runtime now maintains the frame
      pointers for stack transitions.
    * assembler: The verifier that checks for incorrect uses of R15
      when dynamic linking on amd64 has been improved.
    * linker: On windows/amd64, the linker (with help from the
      compiler) now emits SEH unwinding data by default, which
      improves the integration of Go applications with Windows
      debuggers and other tools.
    * linker: In Go 1.21 the linker (with help from the compiler) is
      now capable of deleting dead (unreferenced) global map
      variables, if the number of entries in the variable initializer
      is sufficiently large, and if the initializer expressions are
      side-effect free.
    * core library: The new log/slog package provides structured
      logging with levels. Structured logging emits key-value pairs
      to enable fast, accurate processing of large amounts of log
      data. The package supports integration with popular log
      analysis tools and services.
    * core library: The new testing/slogtest package can help to
      validate slog.Handler implementations.
    * core library: The new slices package provides many common
      operations on slices, using generic functions that work with
      slices of any element type.
    * core library: The new maps package provides several common
      operations on maps, using generic functions that work with maps
      of any key or element type.
    * core library: The new cmp package defines the type constraint
      Ordered and two new generic functions Less and Compare that are
      useful with ordered types.
    * Minor changes to the library: As always, there are various
      minor changes and updates to the library, made with the Go 1
      promise of compatibility in mind. There are also various
      performance improvements, not enumerated here.
    * archive/tar: The implementation of the io/fs.FileInfo interface
      returned by Header.FileInfo now implements a String method that
      calls io/fs.FormatFileInfo.
    * archive/zip: The implementation of the io/fs.FileInfo interface
      returned by FileHeader.FileInfo now implements a String method
      that calls io/fs.FormatFileInfo.
    * archive/zip: The implementation of the io/fs.DirEntry interface
      returned by the io/fs.ReadDirFile.ReadDir method of the
      io/fs.File returned by Reader.Open now implements a String
      method that calls io/fs.FormatDirEntry.
    * bytes: The Buffer type has two new methods: Available and
      AvailableBuffer. These may be used along with the Write method
      to append directly to the Buffer.
    * context: The new WithoutCancel function returns a copy of a
      context that is not canceled when the original context is
      canceled.
    * context: The new WithDeadlineCause and WithTimeoutCause
      functions provide a way to set a context cancellation cause
      when a deadline or timer expires. The cause may be retrieved
      with the Cause function.
    * context: The new AfterFunc function registers a function to run
      after a context has been cancelled.
    * context: An optimization means that the results of calling
      Background and TODO and converting them to a shared type can be
      considered equal. In previous releases they were always
      different. Comparing Context values for equality has never been
      well-defined, so this is not considered to be an incompatible
      change.
    * crypto/ecdsa: PublicKey.Equal and PrivateKey.Equal now execute
      in constant time.
    * crypto/elliptic: All of the Curve methods have been deprecated,
      along with GenerateKey, Marshal, and Unmarshal. For ECDH
      operations, the new crypto/ecdh package should be used
      instead. For lower-level operations, use third-party modules
      such as filippo.io/nistec.
    * crypto/rand: The crypto/rand package now uses the getrandom
      system call on NetBSD 10.0 and later.
    * crypto/rsa: The performance of private RSA operations
      (decryption and signing) is now better than Go 1.19 for
      GOARCH=amd64 and GOARCH=arm64. It had regressed in Go 1.20.
    * crypto/rsa: Due to the addition of private fields to
      PrecomputedValues, PrivateKey.Precompute must be called for
      optimal performance even if deserializing (for example from
      JSON) a previously-precomputed private key.
    * crypto/rsa: PublicKey.Equal and PrivateKey.Equal now execute in
      constant time.
    * crypto/rsa: The GenerateMultiPrimeKey function and the
      PrecomputedValues.CRTValues field have been
      deprecated. PrecomputedValues.CRTValues will still be populated
      when PrivateKey.Precompute is called, but the values will not
      be used during decryption operations.
    * crypto/sha256: SHA-224 and SHA-256 operations now use native
      instructions when available when GOARCH=amd64, providing a
      performance improvement on the order of 3-4x.
    * crypto/tls: Servers now skip verifying client certificates
      (including not running Config.VerifyPeerCertificate) for
      resumed connections, besides checking the expiration time. This
      makes session tickets larger when client certificates are in
      use. Clients were already skipping verification on resumption,
      but now check the expiration time even if
      Config.InsecureSkipVerify is set.
    * crypto/tls: Applications can now control the content of session
      tickets.
    * crypto/tls: The new SessionState type describes a resumable
      session.
    * crypto/tls: The SessionState.Bytes method and ParseSessionState
      function serialize and deserialize a SessionState.
    * crypto/tls: The Config.WrapSession and Config.UnwrapSession
      hooks convert a SessionState to and from a ticket on the server
      side.
    * crypto/tls: The Config.EncryptTicket and Config.DecryptTicket
      methods provide a default implementation of WrapSession and
      UnwrapSession.
    * crypto/tls: The ClientSessionState.ResumptionState method and
      NewResumptionState function may be used by a ClientSessionCache
      implementation to store and resume sessions on the client side.
    * crypto/tls: To reduce the potential for session tickets to be
      used as a tracking mechanism across connections, the server now
      issues new tickets on every resumption (if they are supported
      and not disabled) and tickets don't bear an identifier for the
      key that encrypted them anymore. If passing a large number of
      keys to Conn.SetSessionTicketKeys, this might lead to a
      noticeable performance cost.
    * crypto/tls: Both clients and servers now implement the Extended
      Master Secret extension (RFC 7627). The deprecation of
      ConnectionState.TLSUnique has been reverted, and is now set for
      resumed connections that support Extended Master Secret.
    * crypto/tls: The new QUICConn type provides support for QUIC
      implementations, including 0-RTT support. Note that this is not
      itself a QUIC implementation, and 0-RTT is still not supported
      in TLS.
    * crypto/tls: The new VersionName function returns the name for a
      TLS version number.
    * crypto/tls: The TLS alert codes sent from the server for client
      authentication failures have been improved. Previously, these
      failures always resulted in a "bad certificate" alert. Now,
      certain failures will result in more appropriate alert codes,
      as defined by RFC 5246 and RFC 8446:
    * crypto/tls: For TLS 1.3 connections, if the server is
      configured to require client authentication using
      RequireAnyClientCert or RequireAndVerifyClientCert, and the
      client does not provide any certificate, the server will now
      return the "certificate required" alert.
    * crypto/tls: If the client provides a certificate that is not
      signed by the set of trusted certificate authorities configured
      on the server, the server will return the "unknown certificate
      authority" alert.
    * crypto/tls: If the client provides a certificate that is either
      expired or not yet valid, the server will return the "expired
      certificate" alert.
    * crypto/tls: In all other scenarios related to client
      authentication failures, the server still returns "bad
      certificate".
    * crypto/x509: RevocationList.RevokedCertificates has been
      deprecated and replaced with the new RevokedCertificateEntries
      field, which is a slice of RevocationListEntry.
      RevocationListEntry contains all of the fields in
      pkix.RevokedCertificate, as well as the revocation reason code.
    * crypto/x509: Name constraints are now correctly enforced on
      non-leaf certificates, and not on the certificates where they
      are expressed.
    * debug/elf: The new File.DynValue method may be used to retrieve
      the numeric values listed with a given dynamic tag.
    * debug/elf: The constant flags permitted in a DT_FLAGS_1 dynamic
      tag are now defined with type DynFlag1. These tags have names
      starting with DF_1.
    * debug/elf: The package now defines the constant COMPRESS_ZSTD.
    * debug/elf: The package now defines the constant
      R_PPC64_REL24_P9NOTOC.
    * debug/pe: Attempts to read from a section containing
      uninitialized data using Section.Data or the reader returned by
      Section.Open now return an error.
    * embed: The io/fs.File returned by FS.Open now has a ReadAt
      method that implements io.ReaderAt.
    * embed: Calling FS.Open.Stat will return a type that now
      implements a String method that calls io/fs.FormatFileInfo.
    * errors: The new ErrUnsupported error provides a standardized
      way to indicate that a requested operation may not be performed
      because it is unsupported. For example, a call to os.Link when
      using a file system that does not support hard links.
    * flag: The new BoolFunc function and FlagSet.BoolFunc method
      define a flag that does not require an argument and calls a
      function when the flag is used. This is similar to Func but for
      a boolean flag.
    * flag: A flag definition (via Bool, BoolVar, Int, IntVar, etc.)
      will panic if Set has already been called on a flag with the
      same name. This change is intended to detect cases where
      changes in initialization order cause flag operations to occur
      in a different order than expected. In many cases the fix to
      this problem is to introduce a explicit package dependence to
      correctly order the definition before any Set operations.
    * go/ast: The new IsGenerated predicate reports whether a file
      syntax tree contains the special comment that conventionally
      indicates that the file was generated by a tool.
    * go/ast: The new File.GoVersion field records the minimum Go
      version required by any //go:build or // +build directives.
    * go/build: The package now parses build directives (comments
      that start with //go:) in file headers (before the package
      declaration). These directives are available in the new Package
      fields Directives, TestDirectives, and XTestDirectives.
    * go/build/constraint: The new GoVersion function returns the
      minimum Go version implied by a build expression.
    * go/token: The new File.Lines method returns the file's
      line-number table in the same form as accepted by
      File.SetLines.
    * go/types: The new Package.GoVersion method returns the Go
      language version used to check the package.
    * hash/maphash: The hash/maphash package now has a pure Go
      implementation, selectable with the purego build tag.
    * html/template: The new error ErrJSTemplate is returned when an
      action appears in a JavaScript template literal. Previously an
      unexported error was returned.
    * io/fs: The new FormatFileInfo function returns a formatted
      version of a FileInfo. The new FormatDirEntry function returns
      a formatted version of a DirEntry. The implementation of
      DirEntry returned by ReadDir now implements a String method
      that calls FormatDirEntry, and the same is true for the
      DirEntry value passed to WalkDirFunc.
    * math/big: The new Int.Float64 method returns the nearest
      floating-point value to a multi-precision integer, along with
      an indication of any rounding that occurred.
    * net: On Linux, the net package can now use Multipath TCP when
      the kernel supports it. It is not used by default. To use
      Multipath TCP when available on a client, call the
      Dialer.SetMultipathTCP method before calling the Dialer.Dial or
      Dialer.DialContext methods. To use Multipath TCP when available
      on a server, call the ListenConfig.SetMultipathTCP method
      before calling the ListenConfig.Listen method. Specify the
      network as "tcp" or "tcp4" or "tcp6" as usual. If Multipath TCP
      is not supported by the kernel or the remote host, the
      connection will silently fall back to TCP. To test whether a
      particular connection is using Multipath TCP, use the
      TCPConn.MultipathTCP method.
    * net: In a future Go release we may enable Multipath TCP by
      default on systems that support it.
    * net/http: The new ResponseController.EnableFullDuplex method
      allows server handlers to concurrently read from an HTTP/1
      request body while writing the response. Normally, the HTTP/1
      server automatically consumes any remaining request body before
      starting to write the response, to avoid deadlocking clients
      which attempt to write a complete request before reading the
      response. The EnableFullDuplex method disables this behavior.
    * net/http: The new ErrSchemeMismatch error is returned by Client
      and Transport when the server responds to an HTTPS request with
      an HTTP response.
    * net/http: The net/http package now supports
      errors.ErrUnsupported, in that the expression
      errors.Is(http.ErrNotSupported, errors.ErrUnsupported) will
      return true.
    * os: Programs may now pass an empty time.Time value to the
      Chtimes function to leave either the access time or the
      modification time unchanged.
    * os: On Windows the File.Chdir method now changes the current
      directory to the file, rather than always returning an error.
    * os: On Unix systems, if a non-blocking descriptor is passed to
      NewFile, calling the File.Fd method will now return a
      non-blocking descriptor. Previously the descriptor was
      converted to blocking mode.
    * os: On Windows calling Truncate on a non-existent file used to
      create an empty file. It now returns an error indicating that
      the file does not exist.
    * os: On Windows calling TempDir now uses GetTempPath2W when
      available, instead of GetTempPathW. The new behavior is a
      security hardening measure that prevents temporary files
      created by processes running as SYSTEM to be accessed by
      non-SYSTEM processes.
    * os: On Windows the os package now supports working with files
      whose names, stored as UTF-16, can't be represented as valid
      UTF-8.
    * os: On Windows Lstat now resolves symbolic links for paths
      ending with a path separator, consistent with its behavior on
      POSIX platforms.
    * os: The implementation of the io/fs.DirEntry interface returned
      by the ReadDir function and the File.ReadDir method now
      implements a String method that calls io/fs.FormatDirEntry.
    * os: The implementation of the io/fs.FS interface returned by
      the DirFS function now implements the io/fs.ReadFileFS and the
      io/fs.ReadDirFS interfaces.
    * path/filepath: The implementation of the io/fs.DirEntry
      interface passed to the function argument of WalkDir now
      implements a String method that calls io/fs.FormatDirEntry.
    * reflect: In Go 1.21, ValueOf no longer forces its argument to
      be allocated on the heap, allowing a Value's content to be
      allocated on the stack. Most operations on a Value also allow
      the underlying value to be stack allocated.
    * reflect: The new Value method Value.Clear clears the contents
      of a map or zeros the contents of a slice. This corresponds to
      the new clear built-in added to the language.
    * reflect: The SliceHeader and StringHeader types are now
      deprecated. In new code prefer unsafe.Slice, unsafe.SliceData,
      unsafe.String, or unsafe.StringData.
    * regexp: Regexp now defines MarshalText and UnmarshalText
      methods. These implement encoding.TextMarshaler and
      encoding.TextUnmarshaler and will be used by packages such as
      encoding/json.
    * runtime: Textual stack traces produced by Go programs, such as
      those produced when crashing, calling runtime.Stack, or
      collecting a goroutine profile with debug=2, now include the
      IDs of the goroutines that created each goroutine in the stack
      trace.
    * runtime: Crashing Go applications can now opt-in to Windows
      Error Reporting (WER) by setting the environment variable
      GOTRACEBACK=wer or calling debug.SetTraceback("wer") before the
      crash. Other than enabling WER, the runtime will behave as with
      GOTRACEBACK=crash. On non-Windows systems, GOTRACEBACK=wer is
      ignored.
    * runtime: GODEBUG=cgocheck=2, a thorough checker of cgo pointer
      passing rules, is no longer available as a debug
      option. Instead, it is available as an experiment using
      GOEXPERIMENT=cgocheck2. In particular this means that this mode
      has to be selected at build time instead of startup time.
    * runtime: GODEBUG=cgocheck=1 is still available (and is still
      the default).
    * runtime: A new type Pinner has been added to the runtime
      package. Pinners may be used to "pin" Go memory such that it
      may be used more freely by non-Go code. For instance, passing
      Go values that reference pinned Go memory to C code is now
      allowed. Previously, passing any such nested reference was
      disallowed by the cgo pointer passing rules. See the docs for
      more details.
    * runtime/metrics: A few previously-internal GC metrics, such as
      live heap size, are now available. GOGC and GOMEMLIMIT are also
      now available as metrics.
    * runtime/trace: Collecting traces on amd64 and arm64 now incurs
      a substantially smaller CPU cost: up to a 10x improvement over
      the previous release.
    * runtime/trace: Traces now contain explicit stop-the-world
      events for every reason the Go runtime might stop-the-world,
      not just garbage collection.
    * sync: The new OnceFunc, OnceValue, and OnceValues functions
      capture a common use of Once to lazily initialize a value on
      first use.
    * syscall: On Windows the Fchdir function now changes the current
      directory to its argument, rather than always returning an
      error.
    * syscall: On FreeBSD SysProcAttr has a new field Jail that may
      be used to put the newly created process in a jailed
      environment.
    * syscall: On Windows the syscall package now supports working
      with files whose names, stored as UTF-16, can't be represented
      as valid UTF-8. The UTF16ToString and UTF16FromString functions
      now convert between UTF-16 data and WTF-8 strings. This is
      backward compatible as WTF-8 is a superset of the UTF-8 format
      that was used in earlier releases.
    * syscall: Several error values match the new
      errors.ErrUnsupported, such that errors.Is(err,
      errors.ErrUnsupported) returns true.
      ENOSYS
      ENOTSUP
      EOPNOTSUPP
      EPLAN9 (Plan 9 only)
      ERROR_CALL_NOT_IMPLEMENTED (Windows only)
      ERROR_NOT_SUPPORTED (Windows only)
      EWINDOWS (Windows only)
    * testing: The new -test.fullpath option will print full path
      names in test log messages, rather than just base names.
    * testing: The new Testing function reports whether the program
      is a test created by go test.
    * testing/fstest: Calling Open.Stat will return a type that now
      implements a String method that calls io/fs.FormatFileInfo.
    * unicode: The unicode package and associated support throughout
      the system has been upgraded to Unicode 15.0.0.
    * Darwin port: As announced in the Go 1.20 release notes, Go 1.21
      requires macOS 10.15 Catalina or later; support for previous
      versions has been discontinued.
    * Windows port: As announced in the Go 1.20 release notes, Go
      1.21 requires at least Windows 10 or Windows Server 2016;
      support for previous versions has been discontinued.
    * WebAssembly port: The new go:wasmimport directive can now be
      used in Go programs to import functions from the WebAssembly
      host.
    * WebAssembly port: The Go scheduler now interacts much more
      efficiently with the JavaScript event loop, especially in
      applications that block frequently on asynchronous events.
    * WebAssembly System Interface port: Go 1.21 adds an experimental
      port to the WebAssembly System Interface (WASI), Preview 1
      (GOOS=wasip1, GOARCH=wasm).
    * WebAssembly System Interface port: As a result of the addition
      of the new GOOS value "wasip1", Go files named *_wasip1.go will
      now be ignored by Go tools except when that GOOS value is being
      used. If you have existing filenames matching that pattern, you
      will need to rename them.
    * ppc64/ppc64le port: On Linux, GOPPC64=power10 now generates
      PC-relative instructions, prefixed instructions, and other new
      Power10 instructions. On AIX, GOPPC64=power10 generates Power10
      instructions, but does not generate PC-relative instructions.
    * ppc64/ppc64le port: When building position-independent binaries
      for GOPPC64=power10 GOOS=linux GOARCH=ppc64le, users can expect
      reduced binary sizes in most cases, in some cases
      3.5%. Position-independent binaries are built for ppc64le with
      the following -buildmode values: c-archive, c-shared, shared,
      pie, plugin.
    * loong64 port: The linux/loong64 port now supports
    - buildmode=c-archive, -buildmode=c-shared and -buildmode=pie.

  - go1.21+ change default GOTOOLCHAIN=auto to local to prevent go
    tool commands from downloading upstream go1.x toolchain binaries
    Refs boo#1212669
    * go1.21+ introduce new default behavior that can download
      additional versions of go1.x toolchain binaries built by
      upstream. See https://go.dev/doc/toolchain for details. The go
      tool would attempt toolchain downloads as needed to satisfy a
      minimum go version specified in go.mod of the program
      containing main() or any of its dependencies.
    * Builds in OBS can not access the network, download attempts
      would fail.
    * Builds in OBS should not use third party binary toolchains.
    * When GOTOOLCHAIN is set to local, the go command always runs
      the bundled Go toolchain.
    * Users can override the default GOTOOLCHAIN setting with
      go env -w, stored in in ~/.config/go/env.
* Fri Jun 23 2023 [email protected]
  - Add missing go.env to package. go.env sets defaults including:
    GOPROXY GOSUMDB GOTOOLCHAIN
    Refs boo#1212667
    * Starting in go1.21+ a missing go.env defaults to GOPROXY=''
      resulting in errors e.g. with online cmds e.g. go mod download:
      "GOPROXY list is not the empty string, but contains no entries"
      It is not clear why GOPROXY='' is not evaluated as "the empty
      string".
