Adobe Flash Player 11.3 Beta 3 has been released.

The key features and benefits of Adobe Flash Player 11.3 are:

•Full screen keyboard input — This feature enables support for all keyboard keys available to an embedded SWF running inside of a page without full screen mode( except for  ‘Esc’). It allows developers to determine if the app is in full screen, whether full keyboard input is allowed, and whether the app is able to request full screen (determined by the embed tag parameter).

•Low latency audio support for streaming audio through NetStream — This feature aims to reduce latency for high quality streaming audio playback. It addresses a very special use case of cloud gaming, where the game is rendered at a server and audio and video are streamed to the client.

•Protected Mode for Firefox — Flash Player Protected Mode is a new security enhancement designed to limit the impact of attacks launched from malicious SWF files against Adobe Flash Player when running in Firefox 4.0+ on Windows Vista and higher. This feature is comparable to the Flash Player Protected Mode in Google Chrome browser, Protected Mode in Adobe Reader, and Office 2010 Protected View.

•Flash Player background updates (Mac) — New versions of the runtimes can now be delivered more effectively to the end user with this enhanced updating mechanism (Background update is only available in the release versions of Flash Player).

•Low latency audio support (Sound API) — This enhancement reduces the latency for Sound.play method and changes to volume and pan on SoundTransform. The latency of SAMPLE_DATA event should also be reduced considerably. •Texture Streaming for Stage3D — Provides an ability to upload coarser, lower quality textures on the GPU first and then progressively improve them as more data becomes available.
