XZ Utils 5.6.0 is available at <https://xz.tukaani.org/xz-utils/>.
There currently are no plans to maintain the 5.4.x branch, but releases
could be made if there is community interest.
Here is an extract from the NEWS file:
5.6.0 (2024-02-24)
This bumps the minor version of liblzma because new features were
added. The API and ABI are still backward compatible with liblzma
5.4.x and 5.2.x and 5.0.x.
NOTE: As described in the NEWS for 5.5.2beta, the core components
are now under the BSD Zero Clause License (0BSD).
Since 5.5.2beta:
* liblzma:
- Disabled the branchless C variant in the LZMA decoder based
on the benchmark results from the community.
- Disabled x86-64 inline assembly on x32 to fix the build.
* Sandboxing support in xz:
- Landlock is now used even when xz needs to create files.
In this case the sandbox has to be more permissive than
when no files need to be created. A similar thing was
already in use with pledge(2) since 5.3.4alpha.
- Landlock and pledge(2) are now stricter when reading from
more than one input file and only writing to standard output.
- Added support for Landlock ABI version 4.
* CMake:
- Default to -O2 instead of -O3 with CMAKE_BUILD_TYPE=Release.
-O3 is not useful for speed and makes the code larger.
- Now builds lzmainfo and lzmadec.
- xzdiff, xzgrep, xzless, xzmore, and their symlinks are now
installed. The scripts are also tested during "make test".
- Added translation support for xz, lzmainfo, and the
man pages.
- Applied the symbol versioning workaround for MicroBlaze that
is used in the Autotools build.
- The general XZ Utils and liblzma API documentation is now
installed.
- The CMake component names were changed a little and several
were added. liblzma_Runtime and liblzma_Development are
unchanged.
- Minimum required CMake version is now 3.14. However,
translation support is disabled with CMake versions
older than 3.20.
- The CMake-based build is now close to feature parity with the
Autotools-based build. Most importantly a few tests aren't
run yet. Testing the CMake-based build on different operating
systems would be welcome now. See the comment at the top of
CMakeLists.txt.
* Fixed a bug in the Autotools feature test for ARM64 CRC32
instruction support for old versions of Clang. This did not
affect the CMake build.
* Windows:
- The build instructions in INSTALL and windows/INSTALL*.txt
were revised completely.
- windows/build-with-cmake.bat along with the instructions
in windows/INSTALL-MinGW-w64_with_CMake.txt should make
it very easy to build liblzma.dll and xz.exe on Windows
using CMake and MinGW-w64 with either GCC or Clang/LLVM.
- windows/build.bash was updated. It now works on MSYS2 and
on GNU/Linux (cross-compiling) to create a .zip and .7z
package for 32-bit and 64-bit x86 using GCC + MinGW-w64.
* The TODO file is no longer installed as part of the
documentation. The file is out of date and does not reflect
the actual tasks that will be completed in the future.
* Translations:
- Translated lzmainfo man pages are now installed. These
had been forgotten in earlier versions.
- Updated Croatian, Esperanto, German, Hungarian, Korean,
Polish, Romanian, Spanish, Swedish, Vietnamese, and Ukrainian
translations.
- Updated German, Korean, Romanian, and Ukrainian man page
translations.
* Added a few tests.
