We've covered this upgrade before, and after three months of beta testing, Adobe feels ready to roll this one out as an official update.
The key features that make Flash 10.2 a worthwhile upgrade are:
- Proper full-screen support for multi-monitor systems: At long last, users with more than one monitor would be able to play a full-screen video on one monitor while working with another monitor! Hurrah! This long-overdue feature alone is worth the upgrade.
- Stage Video: Adobe's new API for high-performance video playback across multiple platforms. In simple terms, it makes HD video fast and easy on your computer. The only snag is that developers will have to build in support for it - it's not just a client-side change. Adobe says YouTube, Vimeo, and Brightcove are already hard at work adding support.
- Font smoothing: Flash player isn't all about video, after all. This improvement adds ClearType-like font smoothing.
- Hardware acceleration: Last but not least, Flash 10.2 supports IE 9's hardware acceleration capabilities ("GPU rendering").
