It's fresh. Opera Software unveiled the official version of their speedy web browser just moments ago, although the beta version has been out since April. Simply known as Opera 12, the latest Opera installment will offer enhanced customization options and various smart features previously unavailable on Opera 11. Plug-ins also run independently now. In other words, they are less likely to crash the browser should the plug-ins fail. Anyhow, to give you a gist of what you can expect, here's a quick summary of the new features you can look forward to on Opera 12.
Customized themes are nothing new on Opera, although they were officially known as 'skins' previously. With Opera 12, however, developers have overhauled their existing skinning system to recreate a more lightweight version. The existing skin section will be ported over to addons.opera.com/themes. Designers with formerly published skins on My Opera will be required to re-upload them on addons.opera.com.
Web applications now have direct access to your web camera via Opera 12. In other words, browsers apps such as PhotoBooth and Polaroid (these links are for demo purposes only) are able to utilize your webcam for a variety of interactive purposes, but only with your explicit permission that is.
Improved Security Badge
Opera's Security Badges are presented in a more user-friendly manner, such that it's easier to tell the site's security and privacy policies at a glance. For instance, you'll be forewarned if a site is attempting to geotag your location or enable your web camera.
Additional New Features
As mentioned, plug-ins will run in their own process to prevent the web browser from crashing in the event that the plug-ins do fail. According to Opera's press release, Opera 12 also offers a faster start-up and page-loading time. Enhancements have been made to ensure speedier HTML5 rendering and improved performance on 64-bit systems as well.
