Now the code is clean + under gcc/clang -fsanitize=undefined. Some of these changes + might have a negative effect on performance with old GCC + versions or compilers other than GCC and Clang. The configure + option --enable-unsafe-type-punning can be used to (mostly) + restore the old behavior but it shouldn't normally be used. + + - Improved API documentation of lzma_properties_decode(). + + - Added a very minor encoder speed optimization. + + * xz: + + - Fixed a crash in "xz -dcfv not_an_xz_file". All four options + were required to trigger it. The crash occurred in the + progress indicator code when xz was in passthru mode where + xz works like "cat". + + - Fixed an integer overflow with 32-bit off_t. It could happen + when decompressing a file that has a long run of zero bytes + which xz would try to write as a sparse file. Since the build + system enables large file support by default, off_t is + normally 64-bit even on 32-bit systems. + + - Fixes for --flush-timeout: + * Fix semi-busy-waiting. + * Avoid unneeded flushes when no new input has arrived + since the previous flush was completed. + + - Added a special case for 32-bit xz: If --memlimit-compress is + used to specify a limit that exceeds 4020 MiB, the limit will + be set to 4020 MiB. The values "0" and "max" aren't affected + by this and neither is decompression. This hack can be + helpful when a 32-bit xz has access to 4 GiB address space + but the specified memlimit exceeds 4 GiB. This can happen + e.g. with some scripts. + + - Capsicum sandbox is now enabled by default where available + (FreeBSD >= 10). The sandbox debug messages (xz -vv) were + removed since they seemed to be more annoying than useful. + + - DOS build now requires DJGPP 2.05 instead of 2.04beta. + A workaround for a locale problem with DJGPP 2.05 was added. + + * xzgrep and other scripts: + + - Added a configure option --enable-path-for-scripts=PREFIX. + It is disabled by default except on Solaris where the default + is /usr/xpg4/bin. See INSTALL for details. + + - Added a workaround for a POSIX shell detection problem on + Solaris. + + * Build systems: + + - Added preliminary build instructions for z/OS. See INSTALL + section 1.2.9. + + - Experimental CMake support was added. It should work to build + static liblzma on a few operating systems. It may or may not + work to build shared liblzma. On some platforms it can build + xz and xzdec too but those are only for testing. See the + comment in the beginning of CMakeLists.txt for details. + + - Visual Studio project files were updated. + WindowsTargetPlatformVersion was removed from VS2017 files + and set to "10.0" in the added VS2019 files. In the future + the VS project files will be removed when CMake support is + good enough. + + - New #defines in config.h: HAVE___BUILTIN_ASSUME_ALIGNED, + HAVE___BUILTIN_BSWAPXX, and TUKLIB_USE_UNSAFE_TYPE_PUNNING. + + - autogen.sh has a new optional dependency on po4a and a new + option --no-po4a to skip that step. This matters only if one + wants to remake the build files. po4a is used to update the + translated man pages but as long as the man pages haven't + been modified, there's nothing to update and one can use + --no-po4a to avoid the dependency on po4a. + + * Translations: + + - XZ Utils translations are now handled by the Translation + Project: https://translationproject.org/domain/xz.html + + - All man pages are now included in German too. + + - New xz translations: Brazilian Portuguese, Finnish, + Hungarian, Chinese (simplified), Chinese (traditional), + and Danish (partial translation) + + - Updated xz translations: French, German, Italian, and Polish + + - Unfortunately a few new xz translations weren't included due + to technical problems like too long lines in --help output or + misaligned column headings in tables. In the future, many of + these strings will be split and e.g. the table column + alignment will be handled in software. This should make the + strings easier to translate. + + 5.2.4 (2018-04-29) * liblzma:
