The security issues that are fixed in the latest version could be used to execute arbitrary code and allow cross domain scripting. Besides those fixes several additional updates have been implemented, many of which relate to certificates. This includes untrusted rootstore capabilities, preventing security information documents from being written to disk or fixing a problem that could cause the incorrect calculation of Certificate IDs.

This version of the Opera web browser added support for platform specific features, namely Data Execution Prevention in Windows XP and Windows Server 2003 and Address Space Layout Randomization in Windows Vista. There have also been several miscellaneous updates like fixing a problem with a blank inline search or adding an external source viewer to the Opera web browser.
