-5.2.5 (2020-03-17)
-
-    * liblzma:
-
-        - Fixed several C99/C11 conformance bugs. 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.
