This work is just one year of development since the release of Perl 5.12.0. It contains nearly 550,000 lines of changes from close to 3,000 files, this work was done by 150 authors and committers. The documentation, as always, pays tribute to those people who worked hard on this new version, "Many of the changes included in this version originated in the CPAN modules included in Perl's core. We're grateful to the entire CPAN community for helping Perl to flourish." The success of this version is dependent on the great work of the whole community, a particular note of thanks should go to Jesse Vincent for his coordination skills as release manager for 5.14.
