I didn't notice much public discussion, but in the last month, Perl 5 development has moved to Github. The logistics of the move were mostly handled by Todd Rinaldo although I'm sure there were other people helping.

The change involved moving the main development repository from perl5.git.perl.org to https://github.com/Perl/perl5, moving the issues from rt.perl.org to Github issues, renaming them in the process, and fixing the code that used the hostnames or URLs for decisions.
