Just remember that nothing is official until it is announced on the opera.com front page, so it could be pulled at any time, for any reason.
So please, hold of spreading the word too much until tomorrow, when you will hopefully see the official announcement, along with a full changelog, on opera.com.
And remember, it is not a finished version! There are known bugs and problems, but we'll iron those out for the final version.
Have fun! 🙂
