Opera Software has released a new version of its Opera browser, version 10.62, for Windows, Linux, FreeBSD, and Mac OS X. This release incorporates bug fixes to the user interface, scripting, and the mail/news/chat function. It also incorporates a fix for the Windows “DLL Hijacking” vulnerability. Further information is in the Change Logs; there are separate pages for Windows, Linux/UNIX, and Mac OS X.
I recommend installing this update; you can get the new version via the built-in update mechanism (Main menu: Help / Check for Updates), or you can download versions for all platforms here.
