Among the major features of this release are a completely reworked client/core connection featuring long-awaited reconnection and Solid support. Also added was support for the new DBus-based system tray of KDE and, in some distributions, GNOME (using the StatusNotifier spec). Notification handling got a complete overhaul. Quassel now supports inputting formatted text. IRC authentication is now possible through SASL on networks that support this (e.g. Freenode). As with roughly every release, several new languages and improved translations for already existing ones were added.
