* xz --force now (de)compresses files that have setuid, setgid,
or sticky bit set and files that have multiple hard links.
The man page had it documented this way already, but the code
had a bug.
* gzip and bzip2 support in xzdiff was fixed.
LZMA is a general purporse compression algorithm designed by Igor
Pavlov as part of 7-Zip. It provides high compression ratio while
keeping the decompression speed fast.
XZ Utils are an attempt to make LZMA compression easy to use on
free (as in freedom) operating systems. This is achieved by providing
tools and libraries which are similar to use than the equivalents
of the most popular existing compression algorithms.
