<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.
The location bar is still missing, though. ;)
If you’re interested/or a developer, you can grab the Internet Explorer 9 Platform Preview s3 build here.
From Release Notes: Platform Preview Build 3 requires updates to be installed on both Windows Vista and Windows 7 systems, after which your computer will require a restart. The updates support Platform Preview graphics, media, and printing functionality. The Platform Preview is designed to install these prerequisites automatically. However, if the Platform Preview encounters an error while installing the prerequisites, you can install them manually prior to installing the Platform Preview. To do so, follow the steps on the Install Instructions page.
