New faster release Parrot 6.11.0 "Fischer's Lovebird"

On behalf of the Parrot team, I'm proud to announce Parrot 6.11.0, also known as "Fischer's Lovebird". Parrot is a virtual machine aimed at running all dynamic languages.

Parrot 6.11.0 is available on Parrot's FTP site, or by following the download instructions. For those who want to hack on Parrot or languages that run on top of Parrot, we recommend our organization page on GitHub, or you can go directly to the official Parrot Git repo on Github

Highlights: Performance: 15-25% faster, fixed GC, experimental VMS port.
