Opera Software has released the shipping version of the web browser software, Opera 12.
Opera 12 adds the “Do Not Track” feature and fixes six security vulnerabilities. With the “Do Not Track” feature, users can activate a setting in the program’s Security preferences asking web sites to not track them. This depends, of course, on web sites honouring this request, but move to implement Do Not Track is gaining momentum as all major browsers now support this.
introduces a new type of browser extension: Speed Dial extensions. Instead of handy thumbnails and links to your top sites, users can embed their Speed Dial with extensions that keep them updated instantly.
Other new features are even faster page loading (claimed by Opera), easy to personalising, redesigned security badges, new APIs for windows and tabs and new web standards support.
With the release of Opera 12, Opera Unite and Opera Website are discontinued and removed by default for new users. Opera recommend all developers to move their solutions to the extensions platform. There's also an experimental hardware acceleration WebGL support in this version.
New web standard supports are: WebRTC, HTML5 Drag and Drop, CSS3 Animations and Transitions, Do-Not-Track and CSS Generated Content for Paged Media.
