Along with several functionality in IE9, the Microsoft developers have added support for HTML5 Canvas, and HTML5 audio and video tags. The new HTML5 functionality enables IE9 to deliver interactive content and online video on the browser without the need for any third-party application or browser plugins.
Microsoft is working as fast as it can to launche its beta version, but is also focused on ensuring a quality product and is not prepared to announce availability dates which might force developers to march to the beat of artificial deadlines that could compromise qulity or performance.
The IE9 Platform Preview 3 is available for download. Visit the IE9 Test Drive site for more information and to download PP3.
