XZ Utils Release Notes
======================
+5.2.0 (2014-12-21)
+
+ Since 5.1.4beta:
+
+ * All fixes from 5.0.8
+
+ * liblzma: Fixed lzma_stream_encoder_mt_memusage() when a preset
+ was used.
+
+ * xzdiff: If mktemp isn't installed, mkdir will be used as
+ a fallback to create a temporary directory. Installing mktemp
+ is still recommended.
+
+ * Updated French, German, Italian, Polish, and Vietnamese
+ translations.
+
+ Summary of fixes and new features added in the 5.1.x development
+ releases:
+
+ * liblzma:
+
+ - Added support for multi-threaded compression. See the
+ lzma_mt structure, lzma_stream_encoder_mt(), and
+ lzma_stream_encoder_mt_memusage() in <lzma/container.h>,
+ lzma_get_progress() in <lzma/base.h>, and lzma_cputhreads()
+ in <lzma/hardware.h> for details.
+
+ - Made the uses of lzma_allocator const correct.
+
+ - Added lzma_block_uncomp_encode() to create uncompressed
+ .xz Blocks using LZMA2 uncompressed chunks.
+
+ - Added support for LZMA_IGNORE_CHECK.
+
+ - A few speed optimizations were made.
+
+ - Added support for symbol versioning. It is enabled by default
+ on GNU/Linux, other GNU-based systems, and FreeBSD.
+
+ - liblzma (not the whole XZ Utils) should now be buildable
+ with MSVC 2013 update 2 or later using windows/config.h.
+
+ * xz:
+
+ - Fixed a race condition in the signal handling. It was
+ possible that e.g. the first SIGINT didn't make xz exit
+ if reading or writing blocked and one had bad luck. The fix
+ is non-trivial, so as of writing it is unknown if it will be
+ backported to the v5.0 branch.
+
+ - Multi-threaded decompression can be enabled with the
+ --threads (-T) option.
+
+ - New command line options in xz: --single-stream,
+ --block-size=SIZE, --block-list=SIZES,
+ --flush-timeout=TIMEOUT, and --ignore-check.
+
+ - xz -lvv now shows the minimum xz version that is required to
+ decompress the file. Currently it is 5.0.0 for all supported
+ .xz files except files with empty LZMA2 streams require 5.0.2.
+
+ * xzdiff and xzgrep now support .lzo files if lzop is installed.
+ The .tzo suffix is also recognized as a shorthand for .tar.lzo.
+
+
5.1.4beta (2014-09-14)
* All fixes from 5.0.6
