- update to 5.6.0:

* 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. * 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. - 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. - 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. - Minimum required CMake version is now 3.14. * liblzma: - LZMA decoder: Speed optimizations to the C code and added GCC & Clang compatible inline assembly for x86-64. - Added lzma_mt_block_size() to recommend a Block size for multithreaded encoding. - Added CLMUL-based CRC32 on x86-64 and E2K with OBS-URL: https://build.opensuse.org/package/show/Base:System/xz?expand=0&rev=145

+- update to 5.6.0:
+  * 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.
+  * 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.
+    - 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.
+    - 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.
+    - Minimum required CMake version is now 3.14.
+  * liblzma:
+    - LZMA decoder: Speed optimizations to the C code and
+    added GCC & Clang compatible inline assembly for
+    x86-64.
+    - Added lzma_mt_block_size() to recommend a Block
+    size for multithreaded encoding.
+    - Added CLMUL-based CRC32 on x86-64 and E2K with
+    runtime processor detection. Similar to CRC64, on 32-bit
+    x86 it isn't available unless --disable-assembler is used.
+    - Optimized the CRC32 calculation on ARM64 platforms
+    using the CRC32 instructions. Runtime detection for the
+    instruction is used on GNU/Linux, FreeBSD, Windows, and macOS.
+    - Added definitions of mask values like
+      LZMA_INDEX_CHECK_MASK_CRC32 to <lzma/index.h>.
+  * Licensing change: The core components are now under the
+  *  BSD Zero Clause License (0BSD). In XZ Utils 5.4.6 and
+    older and 5.5.1alpha these components are in the public
+    domain and obviously remain so; the change affects the new
+    releases only.
+  * 0BSD is an extremely permissive license which doesn't
+    require retaining or reproducing copyright or license notices
+    when distributing the code, thus in practice there is
+    extremely little difference to public domain.
+  * liblzma
+    - Significant speed optimizations to the LZMA decoder
+    were made. There are now three variants that can be
+    chosen at build time:
+  * Basic C version: This is a few percent faster than
+    5.4.x due to some new optimizations.
+  * Branchless C: This is currently the default on platforms
+    for which there is no assembly code. This should be a few
+    percent faster than the basic C version.
+  * x86-64 inline assembly. This works with GCC and Clang.
+    The default choice can currently be overridden by
+    setting LZMA_RANGE_DECODER_CONFIG in CPPFLAGS: 0 means the
+    basic version and 3 means that branchless C version.
+  * Added a new filter for RISC-V binaries. The filter can be
+    used for 32-bit and 64-bit binaries with either little or
+    big endianness. In liblzma, the Filter ID is
+    LZMA_FILTER_RISCV (0x0B)
+    - Implemented GNU indirect function (IFUNC) as a
+    runtime function dispatching method for CRC32 and CRC64
+    fast implementations on x86. Only GNU/Linux (glibc) and
+  * xz:
+  - Multithreaded mode is now the default. This
+    improves compression speed and creates .xz files that can be
+    decompressed multithreaded at the cost of increased
+    memory usage and slightly worse compression ratio.
+  - Added new command line option --filters to set the
+    filter chain using liblzma filter string syntax.
+  - Added new command line options --filters1 ...
+    --filters9 to set additional filter chains using liblzma filter
+    string syntax. The --block-list option now allows
+    specifying filter chains that were set using these new options.
+  - Added support for Linux Landlock as a sandboxing
+    method.
+  - xzdec now supports pledge(2), Capsicum, and Linux
+    Landlock as sandboxing methods.
+- enable y2038 mode
+- enable zstd compression, we no longer have bootstrap
+  issues as xz is no longer used
