Opera 12.10 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

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.

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