Opera has released about a month after the beta, the final version of its desktop browser 12:10. She is now available for Windows, Mac and Linux available for download.
The new features include support for high-resolution displays such as Apple’s Retina display and Google’s network protocol SPDY. Also WebSocket, another TCP-based network protocol for bidirectional communication between a Web application and a server is now enabled by default. SPDY is the successor of the Hypertext Transfer Protocol (HTTP). It is faster and safer than this one as it SSL encryption for all connections to the standard makes. The optional browser extension SPDY indicator helps to identify the sites that already support SPDY. To increase security for end-users, operators allowed by house only to install extensions, which have been tested and hosted by Opera .

Developers benefit from new interfaces (APIs). This includes approximately the Context Menu API , with an extension to the right-click menu to add new options. There are also a resource loader API , an API screenshots and an updated version of the URL Filter API .
Also new is support for full-screen interface of HTML 5 , which allows display of videos, games or websites on the entire screen. Opera speaks of a “partial” support, because it takes the most recent version of the API from July 2012 still uses the previous version of February. It also gives some support for the Page Visibility API . She knows by a tab, if he is to see at the moment or not. This enables him to pause as needed to run multiple animations, video or audio, and it is visible again.
