XZ Utils Release Notes
======================
+5.3.2alpha (2021-10-28)
+
+ This release was made on short notice so that recent erofs-utils can
+ be built with LZMA support without needing a snapshot from xz.git.
+ Thus many pending things were not included, not even updated
+ translations (which would need to be updated for the new --list
+ strings anyway).
+
+ * All fixes from 5.2.5.
+
+ * xz:
+
+ - When copying metadata from the source file to the destination
+ file, don't try to set the group (GID) if it is already set
+ correctly. 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.
