New IE10 Platform Preview 2 for download: CSS3 Floats, Drag & Drop, File Reader API, Web Workers, and more

The second release of a Platform Preview (PP) for Internet Explorer 10 is now available. In this PP2, the IE team has implemented a very big number of new site-ready HTML5 technologies and continued working on improving performance.

Some of the new technologies include:

• Positioned Floats
• CSS3 Gradients (on all image types)
• CSS stylesheet limit lifted
• CSSOM Floating Point Value support
• Improved hit testing APIs
• Media Query Listeners
• HTML5: Support for async attribute on script elements
