Catalyst 5.8

Major features of the 5.8 series includes a transition to the Moose object oriented framework, huge refactoring of the test suite, resolution of many outstanding bugs, and lots of new documentation. This release of Catalyst represents over 18,000 lines of code improvements coordinated by its worldwide community members. Despite the huge set of changes and upgrades, it was completed in a little over twelve months.


Catalyst is available for installation via Perl's cpan command line tool:

cpan Catalyst::Runtime

Full backward compatibility was a mandate for this release. Catalyst is very highly tested. The 5.8 code is currently running, unchanged, a Catalyst site that has been up since version 4.3, in 2004. Please bring your upgrade issues to the mailing list or to the Catalyst IRC chat. For reaching the community see:
