Today, in keeping with the pledge to update the preview every eight weeks, the IE team has released Platform Preview 3, which includes
- More HTML5 tag support: <canvas>, <audio>, and <video>
- Web Open Font Format (WOFF) support
- Support for ECMAScript 5, with a side-effect of a 35% improvement in the ACID3 test (from 68 to 83).
There have been over a million downloads of the IE9 Platform Previews thus far – join the fun (oh, and if you’ve already got one of the previews installed, you can simply install Platform Preview 3 right on top of it).
