We expect to release version v5.21.2 on July 20, 2014. The next major stable release of Perl 5, version 22.0, should appear in May 2015.
It's worth noting that there are a few known issues with this build.
Specifically, you may experience test failures for Socket on: Midnight BSD Solaris. And assorted test failures on HP-UX. These will be addressed in a future release.
