Adobe Flash Player 11.4 drives innovation for rich, engaging digital experiences with new features for cross-platform browser-based viewing of expressive rich internet applications, content, and videos across devices. This beta release provides access to the Flash Player 11.4 runtime for Mac OS and Windows desktop environments.

What's new in Adobe Flash Player 11.4 Beta
The beta release provides access to the AIR 3.4 SDK for Windows and Mac to target Windows, Mac OS, iOS and Android. The key features and benefits of AIR 3.4 are

Concurrency (ActionScript Workers) - This feature enable developers to off-load certain tasks like high-latency operations and long-running computations to “workers”. These background workers run concurrently in order to leverage more machine resources and avoid things like UI freezes and allow content to be more responsive.

Stage3D constrained mode - A new parameter to Context3D has been introduced called "constrained profile".  Constrained profile allows Stage3D content to run hardware accelerated on more hardware, especially the Intel GMA chipsets. The Starling framework has been updated to be constrained mode ready.

StageVideo.attachCamera - Provides webcam support for StageVideo. This allows developers to leverage GPU acceleration to render webcam video streams.

Camera.copyToByteArray/Camera.copyToVector - Allow efficient copy of the video frames pixels to an existing ByteArray or Vector.

LZMA support for ByteArray - In addition to zlib compression of ByteArray, we are introducing an additional compression type based on LZMA to compress data inside a ByteArray through ByteArray.compress() and ByteArray.uncompress().

Additional feature details available in the release notes.
