Microsoft has been showing off all sorts of new things at MIX10. New things like… Internet Explorer 9, which was previewed at the developer event, and here’s what we know thus far. As expected it will support HTML5 video, boast a new Microsoft JavaScript engine which is codenamed “Chakra,” and it’ll support new-fangled web technologies like CSS3 and SVG2.
Microsoft says one of its main goals with IE9 is to provide a faster browsing experience — always good news. Preliminary ACID3 tests on the preview show the IE9 scores a 55/100, up from IE8’s dismal 20/100 — a ‘huge’ leap forward no doubt. Microsoft has also confirmed that IE9 will not support Windows XP, but the preview Microsoft is showing off plays nice with Vista SP2 and higher. Microsoft’s also made the first developer preview of Internet Explorer 9 available for download today.
