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 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.
