Adobe have just released a beta of Flash Player 11 for desktop computer’s. This version comes with a good few new features including Stage3D APIs for 2D and 3D rendering, H.264 encoding, 64-bit support and 7.1 surround sound. You can download the beta yourself from the link below. Be warned though, It’s a beta for a reason!! Don’t expect it to work perfectly(Like all versions of flash player).
