All samples and documentation have been updated in the Adobe After Effects 7.0r2 SDK. The addition of SmartFX effect messaging enables 32 bit-per-channel effects processing. Numerous AEGP API enhancements improve After Effects' inter-application responsiveness.

What the heck does that mean? Creative Workflow Hacks posted a blurb on it and explained it well, "if you're a developer and on the Mac this is the first version with Xcode sample projects. So if you've been putting off developing plugins because you didn’t want to buy Code Warrior now's your chance to dive in. I want to do some timed tests between AEGP plugins and scripting and see if it's worth my time to dive into the minutia of C and C++."

Creative Workflow Hacks is a great site. I have to admit, most of it is over my head. Really good stuff. Dale Bradshaw is one smart guy.
