XZ Utils Release Notes XZ Utils Release Notes
====================== ======================
5.1.4beta (2014-09-14)
* All fixes from 5.0.6
* liblzma: Fixed the use of presets in threaded encoder
initialization.
* xz --block-list and --block-size can now be used together
in single-threaded mode. Previously the combination only
worked in multi-threaded mode.
* Added support for LZMA_IGNORE_CHECK to liblzma and made it
available in xz as --ignore-check.
* liblzma speed optimizations:
- Initialization of a new LZMA1 or LZMA2 encoder has been
optimized. (The speed of reinitializing an already-allocated
encoder isn't affected.) This helps when compressing many
small buffers with lzma_stream_buffer_encode() and other
similar situations where an already-allocated encoder state
isn't reused. This speed-up is visible in xz too if one
compresses many small files one at a time instead running xz
once and giving all files as command-line arguments.
- Buffer comparisons are now much faster when unaligned access
is allowed (configured with --enable-unaligned-access). This
speeds up encoding significantly. There is arch-specific code
for 32-bit and 64-bit x86 (32-bit needs SSE2 for the best
results and there's no run-time CPU detection for now).
For other archs there is only generic code which probably
isn't as optimal as arch-specific solutions could be.
- A few speed optimizations were made to the SHA-256 code.
(Note that the builtin SHA-256 code isn't used on all
operating systems.)
* liblzma can now be built with MSVC 2013 update 2 or later
using windows/config.h.
* Vietnamese translation was added.
