IE9 may only be just over three months old, but all eyes are now on the next-gen of Microsoft's, er, "popular" browser - IE10 - following the release of the second platform preview to developers.

The platform preview is the one that was on show in the Windows 8 demo and lets developers get to work using the latest HTML5 tech.

There are "several new technologies" on board including CSS3 Positioned Floats, HTML5 Drag-drop, File Reader API, Media Query Listeners and initial support for HTML5 Forms, which may sound like a load of technical gobbledegook if you're not into programming - but should mean plenty of rich web experiences for you come launch time.

"Developers will be able to build even more amazing sites and applications with IE10’s improved HTML5 support," said Dean Hachamovitch, corporate vice president at Internet Explorer.

"As different browsers support developers using the same markup to achieve the same results with great performance, we can all realize the promise of HTML5 applications. To this end, we have posted over 270 new tests to the IE Test Center and submitted them to the standards bodies."

The IE10 platform preview is available to download now.
