Flash Player 10 has been released, here are the new or enhanced features
3D effects New
Create more intuitive, engaging interfaces using built-in support for 3D effects. Get started quickly without being a 3D master by designing in 2D and easily transforming and animating in 3D. Fast, extremely lightweight, and simple-to-use APIs, along with 3D tools in Adobe® Flash® CS4 Professional software, make motion that was previously accessible only to expert users via ActionScript® language or custom third-party libraries available to everyone.
Custom filters and effects New
Create high-performance, real-time effects for cinematic experiences that quickly engage users. With new Adobe Pixel Bender™, the same technology behind many filters and effects in Adobe After Effects® software, these dynamic and interactive effects can be used both in production with After Effects CS4 and live with Flash Player 10. The Pixel Bender just-in- time (JIT) compiler can also be used to process other types of data, such as sound or mathematical functions, asynchronously in a separate thread.
Advanced text support New
Take advantage of a new, flexible text layout engine that brings print-quality publishing to the web, building on more than 25 years of Adobe expertise in typography. Gain more control over text layout using an extensible library of ActionScript 3.0 text components to flow text and sophisticated typographic elements such as ligatures across multiple columns, around inline images, bidirectionally, vertically, or chained together. Create multilingual rich Internet applications (RIAs) using device fonts that can now be anti-aliased, rotated, and styled, or build your own unique text components.
Dynamic sound generation New
Use enhanced sound APIs to dynamically generate audio and create new types of audio applications such as music mixers and sequencers, real-time audio for games, and even audio visualizers. Work with loaded MP3 audio at a lower level by extracting audio data and supplying it to the sound buffer. Process, filter, and mix audio in real time through the Pixel Bender JIT compiler to extend creative freedom beyond the visual experience.
Drawing API Enhanced
Perform runtime drawing more easily with restyleable properties, 3D APIs, and a new way of drawing sophisticated shapes without having to code them line by line. Developers can tweak parts of curves, change styling, replace parts, and use custom filters and effects, delivering improved throughput, creative control, and greater productivity. Enhancements to the Drawing API add the z dimension, real perspective, textured meshes in 3D space, a retained graphics model, read/write rendering, and triangle drawing with UV coordinates, while adding memory and improving performance.
Hardware acceleration Enhanced
Use the hardware processing power of the graphics card to paint SWF files into the browser and accelerate compositing calculations of bitmaps, filters, blend modes, and video overlays faster than would be performed in software.
Vector data type New
Use the new typed array class for better performance, efficiency, and error checking of data.
Dynamic Streaming New
Show exceptional video with streams that automatically adjust to changing network conditions. Leverage new quality-of-service metrics to provide a better streaming experience.
Speex audio codec New
Take advantage of the new, high-fidelity and open source Speex voice codec, which offers a low-latency alternative for voice encoding. Flash Player also supports ADPCM, HE-AAC, MP3, and Nellymoser audio.
File upload and download APIs Enhanced
Bring users into the experience by letting them load and save files from your web application. New file reference runtime access allows local processing of data without roundtripping to the server.
The latest version of the Adobe Flash Player is 10.0.12.36
