Microsoft IE Business and Marketing senior director Ryan Gavin revealed on the Windows Team Blog that Internet Explorer 9 will be released on Monday March 14th.

The new release offers a faster JavaScript engine, hardware-acceleration for graphics and text, HTML5 support, a redesigned user interface, a Notification Bar, Jump Lists, a new address bar and several other new features.
I mentioned last month that we would be down in Austin, TX for SXSW. Since then there has been plenty of speculation and interest as to what might be happening. Exactly twelve months from the first Platform Preview of IE9, on Monday March 14th we will celebrate the developers and designers who are making a more beautiful web for all of us. We will release the final version of Internet Explorer 9 for download beginning at 9 p.m. Pacific.
