16 Jun 2009I put out the 1.3.0 release earlier this afternoon, here's the release announcement:
On behalf of the Parrot team, I'm proud to announce Parrot 1.3.0 "Andean Swift." Parrot is a virtual machine aimed at running all dynamic languages.
Parrot 1.3.0 is available on Parrot's FTP site, 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.

I picked the name "Andean Swift" to pay homage to the serious optimization work we've done this month. I wanted a fast bird, and naturally I thought of using "Peregrine Falcon" first. However, considering chromatic's awesome work in plugging memory leaks, I thought it would be more fitting to pick a bird that was both fast and small. We can reserve "peregrine falcon" for a future optimized Parrot par excellence. Maybe that will be the one where we introduce the super-fast L1 operations, or a faster concurrent GC, or something else extraordinary.
