Adobe have officially released Flash Player 10.2 for Windows, Mac and Linux.
This release brings a range of performance improvements and feature enhancements. Worth pointing out is Stage Video, a full hardware accelerated video pipeline that improves video playback performance across platforms and browsers by separating the video playback from the DisplayList and offloading rendering to the GPU (where supported).
Additionally, this version of Flash Player offers all the new capabilities previewed in the beta release, like custom native mouse cursors, multiple monitor full-screen support, Internet Explorer 9 hardware accelerated rendering support, and enhanced sub-pixel rendering for much improved text readability.
