Release Notes: This release fixes a security vulnerability through which a manipulated, but properly authenticated client was able to retrieve the backlog of other users on the same core in some cases.
Release Notes: This release fixes a security vulnerability that could occur with Qt 4.8.5+ and PostgreSQL.
Release Notes: This release fixes a bug which caused parts of the nick list (and sometimes the chat lists) not to be shown when using Qt 4.8.
Release Notes: This release fixes a bug in Quassel's CTCP handling that would cause the core to crash when processing a specially crafted CTCP message.
Release Notes: This version mostly contains build system fixes for recent versions of KDE and Qt. Some issues with netsplit handling have also been fixed. Accidentally hidden menu bars can now be re-enabled using the context menu on the chatview. To workarounding the recent flooding issues with Freenode, a quick way to ignore CTCP requests was added. (Though since Freenode has already fixed the problem, using this should no longer be necessary for now.)
