Opera 12.10 for UNIX changelog

Release date: 2012-11-06

Opera 12.10 is a recommended upgrade offering new and improved features, plus security and stability enhancements.

New Features and Important Notes

Operating system compatibility: Windows 8 and Mac OSX

We have added basic touch support for Opera in Windows 8 Classic, so you will be able to scroll, zoom and browse pages and elements easily. As an extra bonus, touch support also works on Windows 7.

Meanwhile, our Mac users will enjoy using the new capabilities of OSX Mountain Lion with Opera. You are now able to use Mountain Lion's built-in share function, using the new Share button in Opera’s address bar, as well as seeing Opera notifications in the Notifications Center.

Extensions, improved

Several new and improved APIs are included in this version of Opera including:

• API for URL filtering
• Context Menu API
• Screenshots API
• Resource Loader API

High-resolution Display Support

Improved support for all high-resolution displays, including Apple's new Retina Displays is included in this release.

Web Specifications Support

Opera 12.10 will include changes in the Opera Presto 2.12 engine up to core-integration-point 388.

SPDY

Support for the SPDY ("Speedy") network standard is included in Opera 12.10. SPDY was designed to cut down the time it takes for a webpage to load, while reducing some of the security risks posed by HTTP.

CSS3 Gradients, Transitions, Animations, and Transforms

All members of these specifications are now available without the -o- prefix and have been updated to the latest published versions.

CSS Site Compatibility

To improve site compatibility and interoperability, Opera 12.10 also introduces aliasing for a selection of vendor-prefixed CSS properties.

• See our blog post to find out more about which prefixed and unprefixed CSS properties are supported

Fullscreen API

Fullscreen API support has been implemented and fully supports Draft 7 of the Fullscreen API specification

Page Visibility API

Basic support for the Page Visibility API specification has been added, including support for visible and hidden

WebSockets

Support for WebSockets has been updated in Opera 12.10 and is now enabled by default.

ICC Profiles

International Color Consortium profile support has been added, ensuring images look as the author intended
