Well, just what the title says. Microsoft has released the Beta 2 of their next Internet Explorer Browser, version 7.

Evaluation of Internet Explorer 7 should start now, but the software should not be used on production systems in mission-critical environments. Internet Explorer 7 Beta 2 Preview will only run on Windows® XP Service Pack 2 (SP2) systems, but will ultimately be available for Windows Vista, Windows XP Professional x64 Edition, and Windows Server 2003.
