Adobe flash CS4

yeeew, it seems like Flash Cs4 has focused on the animation side of flash, like CS3 focused on the revamp of actionscript and adding actionscript3.

There are a ton of cool new animation features such as Inverse Kinematics Engine, new 3D features which will make your 2d object.. well 3d, ow and you have to have a look at this. pretty funky is you ask me. Stage rendering which basically means playing and previewing your movie clips onstage rather than having to export and preview your movie.
Ow and dare i not mention a new tween system which looks pretty swanky, no more creating motion guides or inserting new key frames to tween between, here is a video from Flash on the beach in 2007 to show you what i mean. There are a few more cool animation features, just search it on youtube =D.

Aaron Simpson from ColdHardFlash.com has done an overview of bone structure and inverse kinematics, definitely check it out.

So if your a Newgrounds fan be prepared to see a lot of hose pipe character animation haha, Adobe has made everything a lot easier and added a lot of time savers and i personally can't wait to have a fiddle with Cs4
