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.
