IE8 Available NOW!
Apparently, IE8 was released on March 11, 2009 and is available for download at:
Internet Explorer 8: Home page
I've only been playing with it for a few minutes, but it does seem to be a little faster than IE7. There is a new Tab Grouping feature (turned on by default) which appears to give tabs that have children tabs, and the children tabs themselves, a background color to define them as a group. Tabs that are not part of a group, or are the last remaining tab of a group, have the normal Windows colors until a child tab is created. At first it looks a little funky, but I'm going to leave it on for a while and see if I like it.
If you have run into any troubles, or just have something to say about IE8, please post a comment here. The download was only about 12MB for the 32 bit version, and 24MB for the 64 bit version (which obviously contains the 32 bit version as well).
