Anyway, theres nothing really new about the release except code improvements and bugfixes. But maybe now it's 1.0 more people will download and less sites will display incorrectly . There's a huge hype going on there, mozilla.org is slow as hell as alot of peeps are upgrading.

Edit:

oh damm, I see I posted something someone else allready posted. can't delete this post, sr.
