Perl 5.12.0
“Perl 5.12.0 shipped with no critical regressions reported so far. The new monthly release process, run by multiple release managers, takes the workload off the Pumpking — a whimsical title that traces back to the pre-version-control era of Perl development. ”
Jesse Vincent's release talk for Perl 5.12.0 — the first stable release shipped under his pumpkinship and under the new monthly cadence. Covers the features (package NAME VERSION, yada yada, implicit strictures, Y2038, Unicode 5.2, pluggable keywords, DTrace), the new release-manager model, and the state of the modern Perl ecosystem (Moose, Plack, AnyEvent).
