Opera 11.51 released

August 30th, 2011

Hei All

We just released 11.51 (b1087) with one security issue fixed and with several stability fixes.

We have also added Mac Lion fullscreen support 🙂

See changelog here:


This security update comes right after the Diginotar certificate breach, but Opera does not require a fix for this issue. Opera always verifies that certificates are not revoked, and unlike other browsers Opera does not display sites as secure if access to revocation servers has been blocked by an attacker. Read more about this issue on the Security Group blog.

We wish to thank you all for contributing with testing of 11.51 and will soon be back with more Opera 12 builds for you to play with.
