Microsoft has released the 2nd beta of Internet Explorer 7 to the general public. You can read the release notes, or watch a tour of the new features. Microsoft warns you not to use this beta a production environment: "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 systems, but will ultimately be available for Windows Vista, Windows XP Professional x64 Edition, and Windows Server 2003." Update: You might have been expecting this, but there's already a DoS attack out there for this new beta.
