On behalf of the Parrot team, I'm proud to announce Parrot 0.8.2 "Feliz Loro." Parrot is a virtual machine aimed at running all dynamic languages.

Parrot 0.8.2 is available via CPAN (soon), or follow the download instructions. For those who would like to develop on Parrot, or help develop Parrot itself, we recommend using Subversion on our source code repository to get the latest and best Parrot code.
