There are the release notes.
Of note...
"You can place generator clips in FXScript filter clip wells. Some FXScript filters read only the first frame of the generator clip, whereas others read multiple frames from the clip. For example, the FXScript filters Bumpmap, Gradient Wipe, and Page Peel use only the first frame of a generator clip placed in their clip wells. If you have animated a text generator clip, making the text move, and you place the clip in an FXScript filter clip well, the text appears animated or not depending on which FXScript filter you’ve chosen.

This has bitten me, as I try putting a caustics into a bump map...and the caustics don't do anything. (This creates the look of your footage underwater if you're in Motion.)
