It is standard practice to include a Changes file in your distribution. The
purpose the Changes file is to help a user figure out what has changed
since the last release.
People have devised many ways to write the Changes file. A preliminary
specification has been created (the CPAN::Changes::Spec manpage) to
encourage module authors to write clear and concise Changes.
This module will help users programmatically read and write Changes files
that conform to the specification.
There is no official package available for openSUSE Leap 15.3
