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.
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.
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.
