IE9 Preview 3 released, supports Canvas and lots more
It goes much further than that, however. Other new WCIU features include: Multiple CSS backgrounds, SVG in CSS backgrounds, HTML5 audio, CSS calc(), hsl() and hsla(), and the Canvas Text API. WOFF support is also confirmed (was already expected), and the TTF and OTF font formats also surprisingly appear to be supported now, so @font-face now has proper support instead of partial.
As a result, the default WCIU summary gives IE9 an actual hint of green, beating Safari 3.2 and Opera 10.0. Excellent news, who knows what will come next?
