According to IEBlog, developers can start working with more site-ready HTML5 technologies. Some of the highlights include:

  • Cross-Origin Resource Sharing (CORS) for safe use of XMLHttpRequest across domains.
  • File API Writer support for blobBuilder allowing manipulation of large binary objects in script in the browser.
  • Support for JavaScript typed arrays for efficient storage and manipulation of typed data.
  • CSS user-select property to control how end-users select elements in a Web page or application.
  • Support for HTML5 video text captioning, including time-code, placement, and captioning file formats.

All the features in this platform preview are available to Web pages, now and will be available to Metro-style applications in Windows 8. For a more in-depth explanation on the above mentioned highlights, make sure to hit the link above.
