Severity: N/A

Details

A new package, xz, which provides user-space tools for compressing and
decompressing files with the LZMA algorithm, is now available.

XZ Utils is an integrated collection of user-space file compression
utilities based on the Lempel-Ziv-Markov chain-Algorithm (LZMA) compression
algorithm. LZMA is a general purpose compression algorithm designed by Igor
Pavlov as part of 7-Zip. It provides high compression ratio while keeping
decompression times low.

The xz package includes liblzma, an LZMA library and API; xz, a shell tool
for compressing files; and xzdec, a shell tool for de-compressing files.
The liblzma API is similar to zlib's and the behavior of xz and xzdec will
be familiar to users of gzip. Also, .xz files have similar properties to
files produced by gzip and bzip2, making them easy for users familiar with
these tools to work with. The LZMA algorithm, however, provides generally
better compression ratios than these conventional tools. (BZ#519122)

Anyone interested in taking advantage of this new compression utility
should install this new package.
