At the opening of the Professional Developer Conference 2010, and celebrating 10 million downloads of the IE9 Beta which makes it the most successful and largest Beta program for internet Explorer 9 ever, the Internet Explorer team has just released out a new version of the Developer Preview 6 now available but there’s also a ton of new demos that you can try out on the IE9 Test Drive site.
Platform Preview 6 introduces two new major HTML5 features along with bug fixes and performance enhancements made since the release of Platform Preview 5 and the Internet Explorer 9 Beta. The HTML5 features include CSS3 2D Transforms, which provide a simple, declarative way to translate, rotate, and scale elements in two-dimensional space. Platform Preview 6 also now recognizes HTML5 Semantic Elements as object type HTMLElement and provides default styling for them. It also continues to improve the developer experience, with built-in JavaScript formatting in F12 that quickly turns unreadable, minified code into nicely formatted JavaScript for easier debugging.
IE9 can be installed on systems running Windows 7 and Vista SP2. Both 32-bit and 64-bit systems are supported.
