		<description><![CDATA[At long last, Flash Player 11 has been released and carries with it a raft of exciting new features. Perhaps most exciting is the inclusion of the new Stage3D class (and related libraries) to enable GPU-accelerated graphics rendering. Today&#8217;s article will be the first to cover this new API and discusses one of its features: [...]]]></description>
