IE9 RC released

The IE9 Release Candidate has been released, so all IE9 information has been updated accordingly.
The one new feature added since last Platform Preview is Geolocation, all previous "unknown" features are now "not supported". This puts the default score for IE9 at 62%, the biggest leap any browser version has ever made from the previous one.
It still falls a bit behind other current browsers, being about on par with Firefox 3.6. Notable features missing in IE9 that are supported in all other stable desktop browsers include: CSS3 Border images, CSS3 text-shadow, Web Workers and Offline web apps.
