Delve into the recent Fedora 42 enhancement for xz that introduces vital bug rectifications and improved compression tools, aiming for optimized performance.
New upstream version 5.8.1 (with a rebuild to try and fix a gating problem)

Summary

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.

LZMA is a general purpose compression algorithm designed by Igor Pavlov as

part of 7-Zip. It provides high compression ratio while keeping the

decompression speed fast.
