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...
