Parrot 0.8.1 "Tio Richie" Released!
Message ID:
   On behalf of the Parrot team, I'm proud to announce Parrot 0.8.1 "Tio
   Richie." [1]  Parrot is a virtual machine aimed at running all dynamic

     Rat Creature #1: Comrade! We are about to feast! Quick, get your fat
     carcass behind this bush and get ready!

     Rat Creature #1: Hello, small mammal.... Could you step in here for
     a moment? I've got something to show you....

     Fone Bone: Can't you show me out here, where I've got runnin' space?

     Rat Creature #1: No! No! Please! Step in here -- your friend the
     dragon isn't around, is he?

     Fone Bone: Hey, Ted! Where you goin'?

     Ted: You're on yer own, Bone! (exit stage left)

     Rat Creature #1: Quick, comrade! Start the cooking fire!

     Rat Creature #2: No. You called me fat.

     Fone Bone: Ted! Wait for me!

     Rat Creature #1: (pulls Bone into the bush) Well, well... Look who's
     joined us for supper... Go start the cooking fire!!

     Rat Creature #2: No. You called me fat.

     Rat Creature #1: No?!!! What do you mean, no?!!!

     Rat Creature #2: And it's not the first time you've done it

     Rat Creature #1: Comrade... be reasonable! I wasn't thinking -- I
     was trying to catch our dinner -- this isn't the time -- I take it
     back.... you're not fat.

     Rat Creature #2: Too late!

     Rat Creature #1: Please, comrade! I just want to chop him up for the

     Rat Creature #2: And that's another thing. I'm tired of stew! I want
     to put him in a crust and bake a light fluffy quiche!

     Rat Creature #1: Quiche?! What kind of food is that for a monster to
     eat?! .... Listen, do you think you could come back in half an hour?
     We'll have this straightened out by then!

     Bone: (runs away)

     Rat Creature #1: (beat) Why didn't you stop me?

     Rat Creature #2: Why should I? You're so smart!

     time passes

     Fone Bone: (hanging from a branch in a waterfall) Those rat
     creatures would have to be pretty stupid to follow me on to this
     frail, little branch!

     Rat Creatures: (follow Bone on to the frail, little branch)

     Fone Bone: Stupid, stupid rat creatures!! (branch breaks)

   Parrot 0.8.1 is available via CPAN (soon [2]). You may also see the Parrot
   download instructions[3]. For those who would like to develop on Parrot, or
   help develop Parrot itself, we recommend using Subversion [4] on our source
   code repository [5] to get the latest and best Parrot code.

   Please note the updated Parrot Roadmap [6] and our goals leading to the 1.0
