This avoids a failure on OpenBSD (and possibly on + a few other OSes) where files may get created so that their + group doesn't belong to the user, and fchown(2) can fail even + if it needs to do nothing. + + - The --keep option now accepts symlinks, hardlinks, and + setuid, setgid, and sticky files. Previously this required + using --force. + + - Split the long strings used in --list and --info-memory modes + to make them much easier for translators. + + - If built with sandbox support and enabling the sandbox fails, + xz will now immediately exit with exit status of 1. Previously + it would only display a warning if -vv was used. + + - Cap --memlimit-compress to 2000 MiB on MIPS32 because on + MIPS32 userspace processes are limited to 2 GiB of address + space. + + * liblzma: + + - Added lzma_microlzma_encoder() and lzma_microlzma_decoder(). + The API is in lzma/container.h. + + The MicroLZMA format is a raw LZMA stream (without end marker) + whose first byte (always 0x00) has been replaced with + bitwise-negation of the LZMA properties (lc/lp/pb). It was + created for use in EROFS but may be used in other contexts + as well where it is important to avoid wasting bytes for + stream headers or footers. The format is also supported by + XZ Embedded. + + The MicroLZMA encoder API in liblzma can compress into a + fixed-sized output buffer so that as much data is compressed + as can be fit into the buffer while still creating a valid + MicroLZMA stream. This is needed for EROFS. + + - Added fuzzing support. + + - Support Intel Control-flow Enforcement Technology (CET) in + 32-bit x86 assembly files. + + - Visual Studio: Use non-standard _MSVC_LANG to detect C++ + standard version in the lzma.h API header. It's used to + detect when "noexcept" can be used. + + * Scripts: + + - Fix exit status of xzdiff/xzcmp. Exit status could be 2 when + the correct value is 1. + + - Fix exit status of xzgrep. + + - Detect corrupt .bz2 files in xzgrep. + + - Add zstd support to xzgrep and xzdiff/xzcmp. + + - Fix less(1) version detection in xzless. It failed if the + version number from "less -V" contained a dot. + + * Fix typos and technical issues in man pages. + + * Build systems: + + - Windows: Fix building of resource files when config.h isn't + used. CMake + Visual Studio can now build liblzma.dll. + + - Various fixes to the CMake support. It might still need a few + more fixes even for liblzma-only builds. + + 5.3.1alpha (2018-04-29) * All fixes from 5.2.4. |
