is due out on Tuesday. I really hope it fixes some of the memory leaks from 1.5. Otherwise, the biggest feature I think that they've added is spell checking built into the browser. Of course, there is probably an extension that does this, so it's not that big of a deal. Anyway, I sort of have mixed feeling about this release. I'll definitely upgrade, but I doubt I'll be wowed.
I'm not going to bother with IE7. I can't imagine a world with no extensions.
