-2 is unusable, .3 solves the issues with 3.22
bumped. The previous version, now stable with gnome 3.20 stabilization spams this kind of stuff on terminal: (meld:9853): Gtk-WARNING **: Allocating size to DiffMap 0x12c49a0 without calling gtk_widget_get_preferred_width/height(). How does the code know the size to allocate? So that change is actually also improving 3.20 compatibility, despite NEWS claiming 3.22 for this change (though it might be worse than a warning with 3.22). The issue Toralf was having isn't affected by the bump, just something weird going on otherwise, but bumped anyway of course. I think we might want to stabilize this in ~2 weeks due to the potential compatibility bits and awful spam in previous version with gtk3.20.
