IE9 Preview 2 released, HTML5 mode enabled in FF3.7
The IE team has released a new version of their "Platform Preview", with some great new improvements. For WCIU this means support for Media Queries as well as getElementsByClassName (a DOMContentLoaded table may also be added soon). On the default settings, this means a 48% score, putting it just above Firefox 3.0 and Safari 3.1.
Additionally, the Firefox 3.7 nightlies now have HTML5 mode enabled by default, which means it's now considered supported in the Inline SVG in HTML5 feature.
