Earlier today the newest version of Microsoft’s popular Internet Explorer web browser went into beta testing.

Development of the product has been underway since shortly after the release of IE8.  Contrary to what web developers have come to expect from Microsoft, it looks like IE9 may actually push the envelope, and finally shift enough of the market into CSS 3 and HTML 5.0 to make these standards worth implementing.

If you want to try out some of the new capabilities, Microsoft has set up a site where you can give them a test run.
