Windows/Mac/Linux: Adobe is offering up a "prerelease" of its inescapable Flash software, adding in GPU acceleration for H.264 video in Windows, multi-touch support, and bug fixes. Anyone with Adobe AIR apps can also grab a 2.0 prerelease of that platform.


Yes, you read right—only Windows gets the graphics-card-powered HD acceleration for now. Even though that matches up nicely with YouTube's expected 1080p HD roll-out, it's a shame that Mac and Linux users get left out in the wilds of jerky video. All platforms get support for multi-touch, however, and tweaks that presumably make Flash a tad bit less of a resource hog.


Adobe AIR 2.0 beta, meanwhile, adds in a whole bunch of native computer functionality, including USB access, better networking compatibility, the ability to open a link or file with its native application (making awkward TweetDeck hacks less necessary), and a faster native WebKit browser, among other improvements.
