5.8.2 (2025-12-17)

    * liblzma:

        - Fix the build on ARM64 on glibc versions older than
          2.24 (2016). They don't have HWCAP_CRC32 in <sys/auxv.h>.

        - Disable CLMUL CRC code when building for 32-bit x86 with
          old MSVC versions. This avoids a compiler bug. The exact
          compiler version in which the issue was fixed is unknown,
          but VS...

IMPORTANT: This includes a security fix for CVE-2025-31115 which affects XZ Utils from 5.3.3alpha to 5.8.0. See the security advisory for details.

5.8.1 (2025-04-03)

    * Multithreaded .xz decoder (lzma_stream_decoder_mt()):

        - Fix a bug that could at least result in a crash with
          invalid input. (CVE-202...

5.8.0 (2025-03-25)

    This bumps the minor version of liblzma because new features were
    added. The API and ABI are still backward compatible with liblzma
    5.6.x, 5.4.x, 5.2.x, and 5.0.x.

    * liblzma on 32/64-bit x86: When possible, use SSE2 intrinsics
      instead of memcpy() in the LZMA/LZMA2 decoder. In typical cases,
      this may reduce decompression time by 0-5 %. H...

5.7.2beta (2025-03-08)

    * On the man pages, mark the following LZMA Utils script aliases as
      deprecated: lzcmp, lzdiff, lzless, lzmore, lzgrep, lzegrep, and
      lzfgrep. The commands that start with xz* instead of lz* have
      identical behavior.

      The LZMA Utils aliases lzma, unlzma, and lzcat aren't deprecated
      because some of these aliases are still in common...

5.7.1alpha (2025-01-23)

    * All fixes from 5.6.4.

    * liblzma:

        - Improve LZMA/LZMA2 encoder speed on 64-bit PowerPC (both
          endiannesses) and those 64-bit RISC-V processors that
          support fast unaligned access.

        - x86/x86-64/E2K CLMUL CRC code was rewritten. It's faster and
          doesn't cause false positives from sanitizers. Attributes...
