Opera team made an official announcement about codename of the upcoming Opera version 11.10:
Barracuda: a sleek fish with a torpedo-like body, dagger-like teeth, and a ferocious appetite. Built to hunt in the ocean, it relies on surprise, agility, and bursts of speed to overtake its prey. The barracuda can even consume larger fish.
"Barracuda" is also the code name of the upcoming 11.10 version of the Opera browser. This is the first of a series of Opera versions where each one will have an associated code name.
The first snapshot build of Barracuda will be made available in the near future, and the full feature set will be revealed some time after that.
As a hint, we can mention that another popular Opera feature will be taken to the next level.
