Rakudo's development release cycle is based on Parrot's release cycle. Parrot releases the third Tuesday of each month; Rakudo will generally issue its own development release two days after the Parrot release.
Each development release is given a sequential number and a code name based on an active Perl Mongers group. Rakudo's February 2009 release is #14; prior releases were bundled as part of monthly Parrot releases.
