New in Internet Explorer 9 1.9.8006.6000 Platform Preview 6 (Oct 29, 2010)

  • 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.
