With the update to version 11.11, the Opera developers have closed a critical security hole that enables attackers to inject malicious code. The vulnerability is found in the code for processing framesets: certain frame constructions cause a memory error that eventually allows attackers to inject malicious code.
Other internal changes mainly affect the browser's overall stability, for example, the developers have fixed the cause of a potential installer crash as well as another bug which caused the browser to crash when trying to access https://www.falk.de/

The complete list of changes can be found at the Opera web site. Opera 11.11 is available to download for Windows, Mac OS X and Linux.
