The new updates are expected to be very useful to game developers who are looking to take their games to cross-platform functionality in both mobile devices and the Web. These include more support for iOS (like push notifications and AIR direct deployment without iTunes), hardware-accelerated video and Stage 3D video card/webcam development. Developers will also find support for transparent images with Stage 3D, the ability to leverage hardware resources with concurrency and SWF size reductions. The full release details here.
