Internet Explorer 9 Platform Preview 3 now available for download

Microsoft has released the third Platform Preview for Internet Explorer 9. This build, still aimed towards developers, contains a lot of improvements to Internet Explorer 9’s new Javascript engine and improves support for HTML5, CSS3, SVG 1.1 and DOM.

<AUDIO>, <VIDEO> and <CANVAS> tags from HTML5 are now included as well as hardware rendering is done for <VIDEO> and <CANVAS> elements. Also, some great news for Acid3 test lovers, Internet Explorer 9 now scores 83/100 in the test. While this still doesn’t compare well to Chrome, Firefox or Safari, it’s still a major improvement over previous versions of Internet Explorer. Even the previous platform preview for Internet Explorer 9 scored only 68/100.Dean_PPB3_9

Compared to other pre-release builds of competing browsers, here’s how Internet Explorer 9 Platform Preview 3 fares so far in JavaScript execution time:


A lot of new demos for <CANVAS> and other elements are also available now on the Test Drive website to check the hardware rendering as well as JavaScript execution performance of this build.

The location bar is still missing, though. ;)
