I just tested Flash CC trial version.
Seriously just stay with CS3 or even better good old Macromedia.
No more action script 2 support.
Brush tool still depends on stage zoom and is still messy.
( Here's a list of things they dropped in CC - Thanks Kenney for the link)
But hey you can export videos in flawless quality - i actually did a test video where i spammed the shit out of filters and it exported really nicely...
Oh wait, the video was 2 seconds long and over 500MB in size... Swivel is still superior

So yeah... How ya doin?
