IE9 developers will hold a launch party in Austin, Tx. during the South by Southwest Festival. The release comes exactly 12 months after the first Platform Preview of the browser.

A major new feature of IE9, which has been in beta testing, is its tracking protection feature. IE9’s feature will let users proactively choose which Web sites they do not want tracking them. The default setting is to allow tracking, as is standard in Web surfing today.

The new version of the browser will be available for download starting at 9 p.m., Pacific Time on March 14.
