The first HTML5 conformance test has been released today and Microsoft's Internet Explorer Platform Preview 6 has taken the top spot. Although HTML5 still isn't finalized, it's nice to see Microsoft make such a drastic change in the past few months.
Internet Explorer Platform Preview 6, which is more or less Internet Explorer 9 without the UI, isn't out of beta yet and is already knocking down the competition. Google Chrome 7.0.517.41 beta came in a close second, with Firefox 4 beta 6, Opera 10.60 and Safari 5.0 falling far behind.
The W3C tests performed only tested attributes, audio, canvas, getElementsByClassName, foreigncontent, video and xhtml5. Other tests like CSS3 and many other non-HTML5 related tests were not included in the report. You can see the full report on W3C's website here.
Microsoft is expected to release Internet Explorer 9 Release Candidate (RC) within the next few months, bypassing the beta 2 release.
