Microsoft have released Beta 3 of Internet Explorer 7. If you’re upgrading, you should uninstall Beta 2 before installing Beta 3. This new version has drag and drop tab reordering, some behavior changes, security fixes and feed reading improvements.

Get Internet Explorer 7 Beta 2 for Windows XP SP2

I’ve not downloaded and tried this version yet but I’m looking forward to it. I’m still kinda disappointed at IE7 – I don’t like the new UI much though the rendering improvements are pretty good. Still, many of the issues I had writing JS for IE6 still exist. 

A beta of Mozilla Firefox 2.0 should be out soon.
