New Features and Important Notes

Out-of-Process Plug-ins

Opera now runs plug-ins as a separate process, allowing for more control when a plug-in misbehaves. This feature will enhance security and stability.

  • For more information about why out-of-process plug-ins are important please see our article describing the feature.

64-Bit Mac and Windows Versions

The 64-bit version of Opera will offer performance improvements for some functions and allow Opera more freedom in allocating memory.

Themes

New, lightweight themes make it easier to customize the browser. Install or change themes at the click of a button, without restarting the browser.

  • The themes gallery can be viewed here, and for more information on how to design themes please seeour article describing the new theme system.

Address Field Enhancements

Numerous improvements to the address bar have been made:

  • Improved address field and address bar drop-down suggestions
  • Smart URL shortening in the address field drop-down
  • The page title and the page excerpt will be used for full page search results
  • URL and page content columns in the address field drop-down have been combined

Experimental Full Hardware Acceleration

Hardware acceleration allows Opera to offload graphics rendering from the processor (CPU) to the graphics card (GPU), making graphics intensive operations such as animations faster.

  • This feature is disabled by default. To enable it you may set EnableHardwareAcceleration to 1. WebGL (which takes advantage of Hardware Acceleration) can be enabled by setting EnableWebGL to 1.
  • To find out more about creating webpages with WebGL, please see our developer article.

Right-to-Left (RTL) Script Support Added, Language Support Expanded

RTL support will bring additional stability for certain languages. Persian, Urdu, Hebrew, and Arabic languages added.

Window and Tabs API

Extensions will now be able to interact with tabs, create tab groups, and manage windows.

  • See the Windows and Tabs API for more information.

Opera Unite, Opera Widgets, and Opera Voice Discontinuation

Opera Unite and Opera Widgets will be off by default in Opera 12.00, and will eventually be phased out of the Opera browser in the future. Voice support will be removed as of Opera 12.00, as the voice-detection library is no longer supported by the third-party vendor.

  • To find out more, please see our announcement.
  • Developers are encouraged to move their solutions to the extensions platform, for information on converting a Widget to an extension, please see this article.
