* Multithreaded .xz decoder (lzma_stream_decoder_mt()):
- Fix a bug that could at least result in a crash with
invalid input. (bsc#1240414, CVE-2025-31115)
- Fix a performance bug: Only one thread was used if the whole
input file was provided at once to lzma_code(), the output
buffer was big enough, timeout was disabled, and LZMA_FINISH
was used. There are no bug reports about this, thus it's
possible that no real-world application was affected.
* Avoid <stdalign.h> even with C11/C17 compilers. This fixes the
build with Oracle Developer Studio 12.6 on Solaris 10 when the
compiler is in C11 mode (the header doesn't exist).
* Autotools: Restore compatibility with GNU make versions older
than 4.0 by creating the package using GNU gettext 0.23.1
infrastructure instead of 0.24.
* Update Croatian translation.
- 5.8.0 changelog:
* 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 %. However, when built
against musl libc, over 15 % time reduction was observed with
highly compressed files.
* CMake: Make the feature test macros match the Autotools-based
build on NetBSD, Darwin, and mingw-w64.
* Update the Croatian, Italian, Portuguese, and Romanian
translations.
* Update the German, Italian, Korean, Romanian, Serbian, and
Ukrainian man page translations.
- Summary of changes in the 5.7.x development releases:
* Mark the following LZMA Utils script aliases as deprecated:

* liblzma:
- Fix x86-64 inline assembly compatibility with GNU Binutils
older than 2.27.
- Fix the build with GCC 4.2 on OpenBSD/sparc64.
* xzdec: Display an error instead of failing silently if the
unsupported option -M is specified.
* lzmainfo: Fix integer overflows when rounding the dictionary and
uncompressed sizes to the nearest mebibyte.
* Autotools-based build:
- Fix feature checks with link-time optimization (-flto).
- Solaris: Fix a compatibility issue in version.sh. It matters
if one wants to regenerate configure by running autoconf.
* CMake:
- Use paths relative to ${prefix} in liblzma.pc when possible.
This is done only with CMake >= 3.20.
- Prefer a C11 compiler over a C99 compiler but accept both.
- Link Threads::Threads against liblzma using PRIVATE so that
-pthread and such flags won't unnecessarily get included in
the usage requirements of shared liblzma. That is,
target_link_libraries(foo PRIVATE liblzma::liblzma) no
longer adds -pthread if using POSIX threads and linking
against shared liblzma. The threading flags are still added
if linking against static liblzma.
* Updated translations: Catalan, Chinese (simplified), and
Brazilian Portuguese.
