Stage 3D Accelerated Graphics Rendering (Player & AIR desktop + AIR for TV)
Stage 3D is a new architecture for hardware accelerated graphics rendering developed that provides a set of low-level APIs that enable advanced 2D and 3D rendering capabilities across screens and devices (desktop, mobile, and TV). Using Stage 3D, app and framework developers can now access high performance GPU hardware acceleration, enabling the creation of new classes of rich, interactive experiences. Note: Stage 3D for mobile versions of Flash Player & AIR will be enabled in a future release.
Flash Access Content Protection Support for Mobile
Flash Access content protection support is now available on mobile devices including Android powered smartphones and tablets. In addition, content protection is now supported on tablet devices powered by the BlackBerry® Tablet OS. Note: Flash Access for iOS is not supported at this time.
Flash Access Content Protection Enhancements
New Flash Access content protection features include key rotation support, V3 license chaining, domain support and enhanced output protection and device filtering.
Protected HTTP Dynamic Streaming (HDS)
Protected HTTP Dynamic Streaming (HDS) provides protection for streaming video across screens while eliminating the deployment complexity of a license server.
Similar to NetStream.close() except that it also clears up the last frame held up by NetStream to be displayed on the Video object. Use this instead of NetStream.close() if the NetStream is to be re-used for other streams later. It enforces garbage collection of the video frame and related decompressor objects. The video object will display a blank frame after the use of this method.
H.264/AVC Software Encoding for Cameras (desktop)
Stream high-quality video from your computer's camera with higher compression efficiency and industry stanard support, enabling both immersive real-time communications such as video chat/conferencing and live video broadcasts.
Flash Player and AIR now include support for the JPEG-XR advanced image compression standard (International Standard ISO/IEC 29199-2). The computationally lightweight JPEG-XR format provides more efficient compression than JPEG, enables both lossy and lossless compression support, and adds support for alpha channel transparency.
Enhanced high resolution bitmap support
BitmapData objects are no longer limited to a maximum resolution of 16 megapixels (16,777,215 pixels), and maximum bitmap width/height is no longer limited to 8,191 pixels, enabling the development of apps that utilize very large bitmaps.
High efficiency SWF compression support
Developers can now take advantage of LZMA compression for their SWF files. LZMA compression can reduce SWF size by up to 40%, enabling users to benefit from richer experiences with shorter download times and reduced bandwidth consumption.
G.711 Audio Compression for Telephony
Support interoperability with legacy phone systems via the Flash Media Gateway (FMG) and other third-party clients (through the open RTMP protocol) without the need for transcoding.
Allows ActionScript developers to take advantage of high performance native parsing and generation of JSON-formatted data.
Garbage Collection Advice
Provides smoother, more responsive user experiences by allowing developers to provide hints to optimize garbage collection scheduling.
Cubic Bezier Curves
The cubicCurveTo drawing API allows developers to easily create complex cubic Beziers without requiring custom ActionScript code.
Secure Random Number Generator
Developers can now take advantage of cryptographically secure random number generation to build more secure algorithms and protocols.
Socket Progress Events
Improve management of data transfer using the Socket class by providing a new property to determine the number of bytes remaining in the write buffer and a new event for when data is being sent to the network layer. Using these new APIs, developers can build applications such as file transfer utilities that monitor socket progress and provide responsive feedback.
DisplayObjectContainer.removeChildren and MovieClip.isPlaying
DisplayObjectContainer now implements a removeChildren API allowing developers to quickly remove all of a container's children using a single API call. A new MovieClip.isPlaying property returns the MovieClip's current playing state.
New Features in Flash Player 11
Native 64-bit Support (Flash Player desktop) — Take advantage of native support for 64-bit operating systems and 64-bit web browsers on Linux, Mac OS, and Windows.
Asynchronous Bitmap Decoding (new for Flash Player) — Improve app responsiveness and deliver smoother animation by decoding images on initial load instead of on demand. Images are cached as needed.
TLS Secure Sockets Support (new for Flash Player) — Enables secure communications for client/server applications.

Improved Packaging Engine - iOS - BETA
We're very excited about this new feature. The new packaging engine we're working on can improve iOS packaging time up to 10 times over the current packager! However this feature is still early in development and we'd like to get your feedback. To enable this feature, please use "-useLegacyAOT no" in the ADT command, before the signing options.
Graphics: Buffer Usage flag for Stage3D
We've added a new enum Class called Context3DBufferUsage which defines two constants, STATICDRAW (default) and DYNAMICDRAW. These constants specify how buffers will be used in Stage3D. We've also added a new parameter, called "bufferUsage", to the constructors of VertexBuffer and IndexBuffer. This "bufferUsage" parameter uses one of the constants form Context3DBufferUsage, which will allow you to select the appropriate buffer type according to your needs.
Mobile Workers (concurrency) - Android
Introduced as a beta feature in AIR 3.9, we've continued to improve this feature based on your feedback for its official release in AIR 4.
Support for native resources access by R* mechanism in native extension - Android
Currently, to use the native Android resources in the Android Native Extension one has to use getResourceID() API while typically to access the resource IDs developers use the R.* mechanism. AIR 4.0 onwards, apps developers will be able to access the resources by R.* mechanism. All the dependencies need to be specified in platform.xml as following and all the dependencies and resources to be packaged in the ANE.
Stage3D Creation of Context3D with Profile Array
We've added a new interface to Stage3D.requestContext3DMatchingProfiles(profiles:Vector. ) which will create a Context3D with highest level suitable profile that is in profile array, based on the current hardware. A developer can check the newly added property 'profile' to obtain the current profile that was chosen by the Flash Runtime.
Support for Android 4.4 (KitKat)
We've completed our support testing with AIR against the latest Android 4.4 release. Please let us know if you encounter any problems.
Mac .pkg Installation Support
Deploying Flash Player and keeping it up to date is a critical task for system administrators worldwide. In Flash Player 11.9 we added .pkg support for ease of deployment. In Flash Player 12, we've incorporated feedback from system administrators to improve the workflow and UI.
Internet Explorer 11 on Windows 7 Support
Microsoft has released IE 11 on Windows 7 and we now officially support this combination in Flash Player 12
