The HTML5 improvements of this platform preview 4 release include the following:

- 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.

This release can be downloaded at Microsoft's test drive site is only for the IE10 on the developer preview of Windows 8 and is separate from the current IE10 for Windows 7, which is only at platform preview 2.

New platform previews will be released every 8 to 12 weeks.
