The release of GCMD v1.4.0 is gradually approaching. Currently, the offline documentation is beeing completely revised. Many new features of the current development version haven’t been documented yet. It is planned that string fixation will be in mid of February.
After this deadline, the translation teams of GNOME can start to contribute so we may welcome GCMD v1.4.0 already in March. Stay tuned!
You can have a look at the current work status at GNOME git.
