From the Slackware-Current Changelog:
Fri May 8 18:49:03 CDT 2009
Hello folks! This batch of updates includes the newly released KDE 4.2.3,
but more noticeably it marks the first departure from the use of gzip for
compressing Slackware packages. Instead, we will be using xz, based on
the LZMA compression algorithm. xz offers better compression than even
bzip2, but still offers good extraction performance (about 3 times better
than bzip2 and not much slower than gzip in our testing). Since support
for bzip2 has long been requested, support for bzip2 and the original lzma
format has also been added (why not?), but this is purely in the interest
of completeness -- we think most people will probably want to use either
the original .tgz or the new .txz compression wrappers. The actual
Slackware package format (which consists of the layout within the package
envelope) has not changed, but this is the first support within Slackware's
package tools for using alternate compression algorithms.
