A major new revision of Opera was announced yesterday: 37.0.2178.32.

Opera 37 includes some significant changes:

• The minimum Windows system requirement is Windows 7. Anyone using Opera on Windows XP or Vista will have to stick with earlier versions.
• Opera now has a native (built-in) ad blocker.
• Videos can now be popped out into their own window for viewing convenience.

The new version also includes a variety of bug fixes and performance improvements. You can see a list of all the changes on the official Opera 37 change log. Note: somewhat confusingly, that log shows changes in beta and developer versions going back to February 2016. Opera routinely makes major new versions available to developers and beta testers, and Opera 37 has been available in those forms for a few months.
