The Norwegian-developed Opera web-browser is now up to version 12 and this latest major release packs many features.
We have been talking about Opera 12
going back to last year with its GPU acceleration support, the new Ragnarök HTML5 parser, and other features, but only now in the summer of 2012 is this major update seeing the official light of day.
Among the features being promoted now for Opera 12 include an "instant makeover" with 350 themes being available from Opera's theme catalog, 64-bit support, an updated address field, GPU hardware acceleration, support for Do-Not-Track, CSS3 animations and transitions, HTML5 drag-and-drop, support for Cross-Origin Resource Sharing, improved language support, and a Window and Tabs API.
