Perl 5.14 is still supported at least until 5.18 is released (due very soon!). Also it will receive any critical security patches for another year after this.
Many thanks for all the subsequent up votes on this. Not sure my answer really deserves it but thanks :)
For those that don't know... Perl development is on a fixed annual release schedule. Every April the release candidate for next version of Perl arrives (no not delivered by the Easter Bunny!).
So 5.18-RC0 is due next month and if all goes well then 5.18 final will be released the following month (at which point 5.14 will be moved to its final year of security only patches).
