Hi Seb, > I'd like to point out the issue of new SDK releases and the flash player > minimal version required. As this is a parity release with the Adobe 4.6 SDK it will have the same minimum Flash Player requirements ie Currently the minimum Flash Player 11.1.
It's possible to compile the Apache Flex SDK 4.8 release with flash player 10.2 and above and there should be a patch for this very soon. Thanks, Justin
