Opera 12.10 Beta Changelog

Release date: 2012-10-02

This is a beta version of Opera. It incorporates new features, improvements, and stability adjustments.

Please use this Opera beta only on properly backed up computers.

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:

High-resolution Display Support

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

Web Specifications Support

Opera 12.10 beta 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 beta. 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.

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