GTK releases 3.20, GtkD release 3.3, splendid. :-)
The GtkD distribution though also include GStreamer which is wonderful, at least per se.
The issue of the moment for me is that GStreamer has a different release cycle to GTK. In particular, GStreamer just release 1.8.0. Is this the version used in GtkD 3.3 or are we already in need of a new GtkD?
