Microsoft Releases IE10 Platform Preview 4

By - Source: Microsoft | B 17 comments

Microsoft is now offering the fourth platform preview (PP4) of IE10 for download. The new version demonstrates that IE is no longer trailing the HTML5 trend, but is beginning to help shape the future of web applications.

The improvements in IE10 are almost exclusively tied to JavaScript and CSS3 changes that are part of a future HTML5 platform. Microsoft said that "developers can start working with more site-ready HTML5 technologies" with PP4. The latest version is, like with PP3, only available for the Developer Build of Windows 8. If you are running Windows 7, you will have to stick with PP2, which was released in June and has begun collecting dust.

According to Microsoft, the main changes in PP4 over PP3 are:

- 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 ongoing additions of HTML5 features had turned IE10 into a browser that can now compete with its rivals in terms of HTML5 support. It is still behind Firefox and Chrome, but IE10 has passed Opera and Safari. When Can I Use shows that IE10 supports 83 percent of HTML5 recommended, proposed, and working draft features. IE9 is at 52 percent, while Firefox is currently at 86 percent, and Chrome at 89 percent. Safari is at 77 percent and Opera at 70 percent.

It is safe to assume that, until the final release, Microsoft will continue on this path and aim to turn IE10 into a compelling HTML5 browser specifically on Windows 8.

    IE will always be lagging behind if they release new version only every 1-2 years.

    So they're supposed to release a new version every week when there is a tiny bug fix?

    Sound like any other browsers you know?

    So I have to use Windows 8 and that stupid Metro UI if I want to use IE 10, itself a stupid browser? Remind me where the compelling reason is for upgrading to either when Windows 7 and Firefox/Chrome works so well.

    It's a BROWSER.

    Why does it need to be cutting edge? 98 percent of people use it for facebook and/or porn.
    Christ.

    Yawn. The only, ONLY, reason I have Windows 7 installed is to play games. Otherwise I do everything else in Ubuntu.

    For general use perhaps - you forget about businesses, large and small, who use it on a day to day basis.

    otacon72What a ridiculous statement. If you have to release a new version every month you have a pretty crappy R&D department.


    if you really think its just bug fixes then you really do not know what you are talking about

    LOL most company intranets are still based on IE6, I don't think many will be jumping on the IE10 bandwagon for some time...

    __-_-_-__speed


    at this point the difference between the latest versions of chrome (fastest) and opera (slowest, besides safari, which is just crApp) Is 350 Milliseconds. I can guarantee you plop somebody down in a chair and she won't notice any difference.

    __-_-_-__reliability


    ask any coder and they'll tell you that smushing new code into existing code almost always results in unforseen consequences elsewhere in said code. Take the recent builds of firefox as an example. It prompts to update constantly and, in my opinion, just causes more issues. Fix one thing and it breaks two others. They need to properly test these builds before pushing them out the door, not band-aid the hull and hope it doesn't leak.

    __-_-_-__security


    Although i'll grant you that out of the box, some browsers have more exploitable "features" than others, but bottom line is that any browser is as secure as you make it. You could take IE and disable flash, java, set all permissions to the most secure and the security levels to high, disable cookies etc etc etc.

    In the same vein you could take a build of firefox with adblock, noscript, etc. and in the wrong hands it would STILL get messed up. The number one security is you.


    I stand by my original statement.

    Try IE8 on an average computer, then try a more modern one and see the difference.
    The browsers of late DO add a great deal of speed, reliability and security, for example the sandbox approach for tabs and plug-ins, to prevent your entire browser from crashing and to help prevent your computer getting attacked thorough it. Not to mention hardware acceleration and support for more modern scripts, as said in this article.

    If Microsoft really wanted to help IE. It would get this beta of IE 10 out to Windows 7 users at the very least. Otherwise as fast as the others are updating their browsers. I suspect IE 10 will again fall behind.

    It would be nice if I could install IE10 alongside IE9, but from my past experience with IE9 Preview this probably isn't possible. Or I'm just remembering wrong.
