XZ Utils Release Notes
======================
5.1.2alpha (2012-07-04)
* All fixes from 5.0.3 and 5.0.4
* liblzma:
- Fixed a deadlock and an invalid free() in the threaded encoder.
- Added support for symbol versioning. It is enabled by default
on GNU/Linux, other GNU-based systems, and FreeBSD.
- Use SHA-256 implementation from the operating system if one is
available in libc, libmd, or libutil. liblzma won't use e.g.
OpenSSL or libgcrypt to avoid introducing new dependencies.
- Fixed liblzma.pc for static linking.
- Fixed a few portability bugs.
* xz --decompress --single-stream now fixes the input position after
successful decompression. Now the following works:
echo foo | xz > foo.xz
echo bar | xz >> foo.xz
( xz -dc --single-stream ; xz -dc --single-stream ) < foo.xz
Note that it doesn't work if the input is not seekable
or if there is Stream Padding between the concatenated
.xz Streams.
* 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.
* Added an *incomplete* implementation of --block-list=SIZES to xz.
It only works correctly in single-threaded mode and when
--block-size isn't used at the same time. --block-list allows
specifying the sizes of Blocks which can be useful e.g. when
creating files for random-access reading.
5.1.1alpha (2011-04-12)
* All fixes from 5.0.2
