Adobe Flash Player is the standard for delivering high-impact, rich Web content. Designs, animation, and application user interfaces are deployed immediately across all browsers and platforms, attracting and engaging users with a rich Web experience.
The table below contains the latest Flash Player version information. Adobe recommends that all Flash Player users upgrade to the most recent version of the player through the Player Download Center to take advantage of security updates.
ActionScript is the powerful object-oriented programming language of the Adobe® Flash® Player runtime environment. Based on ECMAScript, the international standardized programming language for scripting, ActionScript 3.0 further advances the language to offer developers a robust programming model for rich Internet applications (RIAs). Developers can achieve superb performance and ease of development to facilitate highly complex applications, large datasets, and object-oriented, reusable code bases. Executed within the new ActionScript Virtual Machine (AVM2) in Flash Player 9, ActionScript 3.0 delivers breakthrough performance for the next generation of RIAs. To accelerate the development of this standards-based approach for creating rich and engaging Web applications, Adobe has contributed source code behind AVM2 to the Mozilla Foundation who hosts the open source project, called Tamarin.
ActionScript 3.0 is compliant with the ECMAScript Edition 3 (ECMA-262) standard.
* ECMAScript for XML (E4X) enables easy manipulation of XML documents using a familiar syntax.
* Regular Expressions save coding time for string search and manipulation procedures.
* DOM Level 3 Events help developers maintain better object-oriented code using the standard W3C event model.
* Namespaces and Packages improve code organization and encourage logical application structure.
* Enhanced debugging and profiling data reduce testing time and facilitate integrating Flash applications into automated testing environments.
* Improved error handling and exceptions enable the development of more secure, robust applications.
New virtual machine
Flash Player 9 includes a new, highly optimized ActionScript Virtual Machine (AVM) known as AVM2. Built from the ground up to work with the next generation of ActionScript, the new virtual machine is designed to deliver the performance and features to support the needs of rich Internet application developers. AVM2 supports full runtime error reporting, built-in debugging, and binary socket support so developers can extend the player to work with any binary protocol. Flash Player 9 also contains AVM1, which executes legacy ActionScript for maintaining backward compatibility with existing content.
New H.264/HE-AAC options
Flash Player 9 includes H.264 video and High Efficiency AAC (HE-AAC) audio codec support that opens up a broad ecosystem and selection of standards-based video — up to HD quality — that developers can leverage in their applications. Supporting a subset of MPEG-4 Part 12 (container) and Part 14 (H.264), including baseline, main and high profiles, Flash Player can play back existing MP4, M4A, MOV, MP4V, 3GP and 3G2 content.
Flash Player Cache
The Flash Player cache enables common components, such as the Flex Framework, to be cached locally and then used by any SWF from any domain. Use of the Flash Player cache can significantly reduce SWF file sizes and speed application download times.
Flash Player 9 builds on improvements in Flash Player 8 to execute content and applications faster than ever before with a number of performance improvements:
* Experience up to ten times faster ActionScript 3.0 execution with the new virtual machine and optimized compiler.
* Increase content and application speeds through faster application startup times and a 50% reduction in memory footprint.
* Accelerate rendering performance through more efficient, cached vector graphics.
* Improve text readability and get faster, smoother scrolling of large text blocks with optimized text rendering routines.
* Speed the rendering of vectors, bitmaps, filters and video, including true 1080p video, with new multi-core support that takes advantage of up to 4 CPUs.
* Improve the performance and quality of full-screen video through the use of hardware scaling.
* Enhance the quality and rendering performance of downscaled images using a new algorithm for scaling bitmap images.
Flash Player enforces security sandboxes for applications, content, data, and URLs to safeguard sensitive data and help ensure safe browsing for end users.
