The new version comes right on time (it was due September 1st), and we've covered alpha, beta and RC versions, so there are no huge surprises here. Perhaps the biggest question is: will this milestone change anything as far as Opera's worldwide reception goes? It hasn't happened so far with earlier versions, but perhaps the big 10 at the end accounts for something. In any case, we'll be monitoring Opera's market share closely in the following months.
As far as features go, the biggest new addition is Opera Turbo, which makes browsing fast even when you're on a slow internet connection. Other novelties are a fresh appearance, enhanced speed (especially on resource intensive sites such as Gmail or Facebook), an improved Opera Mail, auto updating (very important for improving the overall security of the browser), a personalized Speed Dial feature, and resizable, thumbnail tabs.
