Adobe has recently updated flash player to 22.214.171.124. Flash Player 9 now includes H.264 standard video support, the same standard deployed in Blu-Ray® and HD-DVD® high definition video players, and High Efficiency AAC (HE-AAC) audio capabilities. The latest update also features hardware accelerated, multi-core enhanced, full-screen video playback for high-resolution viewing across major operating systems and browsers.

The update also fixes a nasty install bug that broke a lot of flash detection scripts ala swfobject in the Active X version. So if you were going to sites with the last version and it was telling you that you didn’t have flash installed it should be fixed by this update.
