Adobe has released public beta versions of Flash Player 11 and AIR 3.

The desktop beta of Flash Player 11 offers new features for cross-platform browser-based viewing of expressive rich Internet applications, content and videos across devices. Some of the features from the Flash Player Incubator, such as Stage 3D (codenamed Molehill) and 64-bit support, have been moved into this beta release.

Key benefits of the Flash Player 11 desktop beta include Stage3D APIs, which support highly interactive visuals to improve collaboration on 3 dimensional models, 64-bit support for Mac OS X, as well as Windows and Linux and the ability to integrate voice/telephony into business apps using the G.711 audio compression codec as well as encode higher quality video locally using H.264 /AVC SW Encoding.

In addition socket progress events allow developers to build advanced filesharing apps like FTP clients to send large amounts of data, while the addition of HD surround sound enables delivery of full HD videos with 7.1 channel surround sound directly to AIR powered TVs.

The beta of Adobe AIR 3 introduces enhanced features that provide developers a consistent and flexible development environment for the delivery of out-of-browser applications across devices and platforms.

AIR 3 delivers innovation for rich engaging applications with performance improvements that deliver advanced graphics rendering, high definition video and consistent reach across operating systems and devices. AIR 3 has a special focus for those interested in developing console quality games, delivering video or scalable enterprise applications.

The AIR 3 desktop runtime beta is provided to ensure current AIR 2.7 and AIR apps targeting older version of AIR are compatible with this upcoming release of AIR 3. The AIR 3 SDK is not yet available as a public beta.
