Microsoft releases IE10 Platform Preview 2

Microsoft today has announced the availability of the second platform preview for its upcoming browser, Internet Explorer 10. The first platform preview was released in April. This new platform preview contains the same HTML5 engine seen in the recent public Windows 8 demos.

According to Microsoft, developers can start working with several site-ready HTML5 technologies for building “beautiful, interactive Web applications with great performance and security” with the second Platform Preview. You can read the full change list here in the IE10 developer guide. Here is a quick overview on whats new:

  • Beautiful and interactive Web applications are easier to deliver with support for several new technologies like CSS3 Positioned Floats, HTML5 Drag-drop, File Reader API, Media Query Listeners and initial support for HTML5 Forms.
  • HTML5 Application performance improves across the board, as well as the ability to deliver better performance with more efficient use of battery life with new technologies like Web Workers with Channel Messaging, Async script support, and others.
  • Web application security improves using the same markup with support for HTML5 Sandbox for iframe isolation.

IE10 continues IE9’s precedent of enabling Web applications to do more in the browser without plug-ins. It also continues the pattern of offloading work to the parts of a PC that are best suited for them, like the GPU for graphics, and different processor cores for background compilation of JavaScript.

Microsoft has been working on tying together Internet Explorer 10’s Trident rendering engine with Windows 8. Microsoft is expecting developers to use HTML5, Javascript, and CSS to build new immersive apps for Windows 8 and this new browser is yet another tool in doing so. Keep in mind that this platform preview has no toolbar, no address bar, and none of the regular menus.
