The best alternative is to uninstall Flash from your system and download Google Chrome as it has Flash build into it and you're not vulnerable unless you're browsing in Chrome. If Safari is your main browser, as mine is, then you need to open Safari Preferences, go to Advanced and click the checkbox for 'Show Develop menu in menu bar'. Mac users interested in Flash player os x 10.5.8 generally download: Flash Player 26.0 Free Flash Player 10.1 is Adobe's last version of the popular Flash player. About Adobe Flash Player for Mac The Adobe Flash Player is a widely distributed proprietary multimedia and application player created by Macromedia and now developed and distributed.
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 releaseEnter your state here.
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.
NetStream.dispose()
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.
JPEG-XR support
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.
Native JSON (JavaScript Object Notation) Support
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
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.
