Opera is now working to make another big release, which will be Opera 11. There has been a beta release of Opera 11 Build 1060 and i'm pretty sure that it will be released this year. Their latest version is 10.63 and it's has been quite mature to compete with others like Firefox, Chrome, and Safari (i always left IE behind).
I still don't see any release notes on the beta version of Opera, but i think it will be another big release by Opera team. I do hope they will also release an update for Opera Mini. It has been some time since they release an update for the product.
