(It was getting boring seeing a frillion people in #opera every day asking, "when will Opera 8 be released???" ;))
Mind you, it's not announced on the Opera site yet, but you can download it from one of the many FTP servers.
Opera's official one, ftp.opera.com, is getting a tad hammered right now, unsurprisingly (but you can still get in and download speedily if you use a FTP program rather than visiting it with your browser of choice) - you can find a list of mirrors here.
As usual for Opera, it rocks. :D I especially love the "fit page to window width" option. Yay, no more pages sidescrolling on me :D
