Perl 5.12.0
Perl 5.12 was recently released with several new features and improvements but no critical regressions reported so far. The "Pumpking" or project leader explained that development releases are now made monthly by release managers, reducing the workload on the Pumpking. Contributors now make the majority of changes to Perl, with over 70 unique authors contributing monthly.
