Internet Explorer 9 to launch to public on 15 September

IE9 will run on Windows XP


Microsoft yesterday updated its bare-bones preview of Microsoft Internet Explorer 9 (IE9) for the last time, saying that the next release would be a beta build.

Although Microsoft hasn't named a release date for IE9's beta, the six-to-eight week stretch between each Platform Preview may provide a clue: If the company sticks to the same gap between the fourth preview and the beta, the latter should show on or after September 15 - confirming previous messages from Microsoft.


In IE9 Platform Preview 4, Microsoft has integrated its new JavaScript engine into the browser, finished its work on hardware acceleration and boosted performance in several areas, including the Acid3 test, said the IE team's leader.

"The IE9 platform is nearly complete," said Dean Hachamovitch, general manager of IE, in a detailed post on the browser's blog Wednesday.


Unlike production versions, the IE9 preview can run alongside other editions, such as IE7 on Vista or IE8 on Windows 7. However, neither the Platform Preview nor the final version of IE9 will run on Windows XP, a sticking point with some users of that nine-year-old operating system.
