Opera has released version 12 of its web browser.
If you have been following browser technologies, you may know that Opera has been promising hardware acceleration for more than a year and originally promised this feature to be available with version 11. It's not final, but explicitly described as "experimental", so don't expect to function flawlessly just yet.
And just in case you are wondering, yes, Opera declined to comment on the rumor that it may soon turn into the official Facebook browser. Opera 12 can be downloaded from opera's homepage.
