There are a range of reasons for early adopters to download and start testing the second public platform preview of Internet Explorer 10, released on June 29th, 2011, the most important of which is related to the evolution of web standard support compared to IE9 and IE10 PP1. Dean Hachamovitch, Corporate Vice President, IE, provided this invitation to web devs: “we encourage developers to try out the improved innerHTML support in this second Platform Preview of IE10.”

And Microsoft made sure to put together a series of video demonstrations focused on the enhancements introduced in Internet Explorer 10 Platform Preview 2.

Said videos are live on Channel 9, but I’ve also embedded below, in order to give you a taste of what IE10 PP2 is capable of. If you’re involved in web development, you should take a look at the materials shared by the software giant.

There are a number of improvements in IE10 PP2, with the Redmond company opting to highlight the following in the developer guidance it’s providing for this preview release:

•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 •HTML5 Drag and Drop •HTML5 File API •HTML5 Sandbox •HTML5 Web Workers •Web Performance APIs: requestAnimationFrame , Page Visibility API and setImmediate.

The IE10 PP2 demos involve: A look at How Stuff Works in IE10; Web Workers; A look at Positioned Floats in IE10; A look at Web Worker Fountains in IE10; and A look at Magnetic Poetry in IE10. You will be able to find them all embedded at the bottom of this article.
