It’s bright, warm, and sunny in Oslo. Naturally all the hardcore geeks are indoors making you the next version of Opera Next. Opera 12.50 will be codenamed ‘Marlin’ and it is starting off strong. Here are some of the highlights that are still works-in-progress: An implementation of the Clipboard API, support for some -webkit prefixed CSS properties, a redesigned keyboard event handling,and integration with Mac OS X 10.8’s Notification Center. Lets dive into it!
Clipboard API exposes the following new events: copy, cut, and paste; for text/plain and text/html content.
Opera’s keyboard event handling has been updated to DOM Events Level 3 and includes various changes to improve our compatibility in the area of key handling.
As previously announced, a subset of widely used -webkit- prefixed CSS properties are now mapped to their -o- counterpart. The supported properties include -webkit-box-shadow, -webkit-transform, -webkit-transform-origin, -webkit-border-radius, -webkit-border-top-left-radius, -webkit-border-top-right-radius, -webkit-border-bottom-left-radius, -webkit-border-bottom-right-radius, -webkit-transition, -webkit-transition-delay, -webkit-transition-duration, -webkit-transition-property, and -webkit-transition-timing-function. You should, however, not rely solely on -webkit- prefixes!
Users on the yet-to-be-released Mac OS X 10.8 “Mountain Lion” will see notifications integrated into the system wide Notification Center instead of seeing notifications through Growl. Older system versions will still see notifications through Growl. Settings are available in Preferences: Advanced: Notifications as well as in System Preferences: Notification Center: Opera Next.
- Key event handling on Mac has some remaining legacy issues
WARNING: This is a development snapshot: It contains the latest changes, but may also have severe known issues, including crashes and data loss situations. In fact, it may not work at all.
