Opera has also worked in improving the browser in ways that might not be that visible to the everyday user. The new browser supports features such as Notification Center in the newest version of Mac OS X and supports the Retina Screen in newer Macs. With the new version of Mac OS X, called Mountain Lion, Opera 12.10 uses the built-in sharing functionality to e.g. share a cool site on Twitter or via email.
Built-in support for the SPDY protocol also improves and secures connections. Gmail and Twitter have already started using SPDY to supplement the HTTP protocol.
The WebSocket API is supported and turned on by default in Opera 12.10. Opera now also supports ICC color profiles and color management.
Support for Flexbox and @supports gives website developers more control of how their website appear in the end users' browsers.
Last but not least, the latest Opera desktop browser offers basic touch support in Windows 8 classic and pinch-to-zoom support in Windows 8.
The final version of Opera 12.10 is available from www.opera.com.
