Parrot 0.5.1 "Hatachi" Released!

[ #35137 ]


Silver flow the streams from Colos to Erui
In the green fields of Lebennin!
Tall grows the grass there. In the wind from the Sea
The white lilies sway,
And the golden bells are shaken of mallos and alfirin
In the green fields of Lebennin,
In the wind from the Sea!

On behalf of the Parrot team, I'm proud to announce Parrot 0.5.1 "Hatachi." Parrot is a virtual machine aimed at running all dynamic languages.

Parrot 0.5.1 can be obtained 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 or SVK on our source code repository to get the latest and best Parrot code.

Parrot 0.5.1 News:
- Documentation
+ PDD19 (PIR) - reflect state on the ground; incorporate old IMCC docs
+ PDD25 (Concurrency) - launch out of draft
+ Improve documentation of deprecated parrot features.

module/class declarations, methods
