Microsoft released Internet Explorer 9 platform preview 3 today, marking the third and possibly final release prior to the beta phase.
The updated platform preview code includes support for the HTML5 video tag. Platform Preview 3 includes support for HTML5 video and audio tags, 2D graphics using the canvas tag and embedded fonts using the WOFF standard. Earlier this month Microsoft demonstrated IE9 vs Safari 5 and the company has pushed out a number of updated HTML5 tests on its test drive today.
Microsoft is also planning broader support for HTML5 in Internet Explorer 9 through its new script engine. Microsoft recently performed W3C Web Standards tests on IE9, including HTML5, SVG 1.1 2nd edition, CSS3 media queries, CSS3 borders & backgrounds, CSS3 selectors, DOM level 3 core, DOM level 3 events and DOM level 2 style. Microsoft, with the help of W3C, performed a total of 192 tests on a variety of browsers. Internet Explorer 9 scored 100% in all eight tests, while every other browser, except Firefox in DOM level 2 style tests, didn't score perfect in any of the test categories.
Microsoft originally began scouting for Internet Explorer 9 beta testers in March. In an email to testers, Justin Saint Clair - Program Manager of Internet Explorer invited testers to join a "select group of IE9 Tech Feedback participants." Neowin understands that Microsoft will introduce a beta of Internet Explorer 9 in August. Today's Internet Explorer 9 Platform Preview 3 is available at Microsoft's IE Test Drive site.
