CMake is now used instead of Autotools. ISZ, CSO, and DMG file filters were added. The DAA parser was converted to a file filter, and support for the related GBI format was added. Audio fragment was converted to a file filter. The image analyzer now displays disc structures. Contextual features, support for GObject introspection, better caching, support for GZIP and XZ compressed images, and support for ECM'ed files was added. The CIF parser was improved. Mode setting was fixed. Partial support was provided for (one track) MDX images. gCDEmu can now act like a Unity indicator. GVFS support was improved.
The dbus and gconf bindings have been switched out with newer GDBus and Gsettings, which is part of the New GiO framework in GObject. The Gnome client was switched from GTK2 bindings to GTK3 using the new pygobject introspective binding. There's been a major code cleanup as well. This release has partial CSS support, bash completion, parser fixes, and analyzer gfx fixes, and is probably python3 ready.
In addition to bugfixes and some cleanup, this release brings a major rewrite of both the daemon and the clients. The CDEmu daemon is not a traditional "daemon" anymore. Instead, it is a regular application which utilizes the D-Bus (auto)start facility for both session and system bus instances. Both cdemu-client and gCDEmu have been changed to single-file Python scripts. gCDEmu has been changed from a GNOME applet into a standalone Gtk application.
