Parrot 0.6.2 "Reverse Sublimation" Released

On 20 May 2008, chromatic released Parrot 0.6.2. Read on for the Parrot 0.6.2 release announcement or download Parrot 0.6.2 from CPAN.

They were walking to the Hemlock, the Rooster and the Mice, and the Mice kept looking at one another, questioning.

"We don't know what the future holds, do we?" said Chauntecleer. The Mice all shook their heads. They knew very little of anything. "If," said Chauntecleer, "I say, if I don't come back again, then you must make this food to last a long, long time. I trust your prudence, don't I?" he asked, and they nodded automatically, but their eyes were very big. "And I trust your integrity, right?" They nodded. "And you are mature, now, and I respect your maturity, isn't that so?" Poor Mice, they nodded and nodded, and they blinked, and they nodded. They looked afraid. "Good," said Chauntecleer. "I know I won't be disappointed.

In this way he gave each Mouse a manhood. They couldn't talk to him just now, having so much to turn over in their minds. But neither did they cry.

On behalf of the Parrot team, I'm proud to announce Parrot 0.6.2 "Reverse Sublimation." Parrot is a virtual machine aimed at running all dynamic languages.

Parrot 0.6.2 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 or SVK on our source code repository to get the latest and best Parrot code.
