Microsoft announced on Tuesday the availability of its fourth Internet Explorer 10 platform preview.

Internet Explorer 10 platform preview 4 is available within the latest developer preview of Windows 8. The latest platform preview includes even greater support for the latest HTML5 standards. Microsoft has created a unique new Metro experience for Internet Explorer 10 inside Windows 8 but fully supports the standard desktop interface too. The platform preview 4 release includes the following updates:

  • 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.

The company previously delivered platform preview 3 in September and has revealed that the final version of Internet Explorer 10 will only be available for Windows 7 and 8. Microsoft confirmed in April that it has no plans to offer IE10 to Vista or Windows XP users. Future platform previews of Internet Explorer 10 will be made available every 8-12 weeks.

You can download Internet Explorer 10 platform preview 4 at Microsoft’s IE test drive site.

    I have been using IE10 on Windows 8 and it is brillient in both Metro UI and desktop UI. I hope they make IE10 best browser available when it finally release !!!

    Looking forward to using the JavaScript typed arrays! They will allow JavaScript to handle number crunching of large data sets much more efficiently! Some basic forms of audio/image processing will now be practical too.

    what I don’t understand is why aren’t they pushing IE updates instead of these stupid platform previews. don’t they get it? their strategy has failed. they need to follow mozilla to chase chromes small but frequent updates instead of timing IE to windows releases.

    • Hino Musouka

      But I suppose they have to deal with a little bit different ecosystem. IE, I assume, is still more integrated into Windows than any other browser and quick, untested updates could be dangerous to system stability, so we only get an update once a month or even less frequently :( Still, I like my Opera to update and fix some bugs every now and then…

    Can we just take IE from Windows 8 and put it on Windows 7 and just RTM it already?

    Now, the chrome performance comparision for seattle rain is not fair, because latest chromium has gpu composition for everything, so there it runs at 60 fps. I wonder what makes the difference from IE10 PP4 to PP3, where fps is really low, thought they already have full gpu acceleration in IE9? Edit: Well, actually I wanted to comment this at:
