As we'd previously reported, a beta of Microsoft Internet Explorer 9 will be available to the public on 15 September. Microsoft announced on its Windows Team Blog that it will launch Internet Explorer 9 at a media event in San Francisco on that day.

Microsoft announced a "platform preview" of IE 9 back in March. The Platform Preview was basically the IE 9 rendering engine presented in a plain window - no toolbars, no extra features. IE 9 will feature better support for new web technologies such as HTML5 and CSS3. It'll also provide hardware acceleration for rendering graphics and text on a web page and a faster JavaScript engine for better web app performance, among other features.

We don't yet know what the IE 9 interface will look like, or what other features it'll have, so we'll have to wait until next month for that.

For more on Microsoft's "Beauty of the Web" IE 9 launch event, see the Windows Team Blog. And see our earlier post on the IE 9 Platform Preview for additional details.
