GTK+ 3.89.5 is the fifth development build of the GTK+ 4 stable series, which should hit the stable channel sometime after the release of the GNOME 3.24 desktop environment next week on March 22, 2017. It brings various Quartz improvements, among which we can mention support for full-screen CSD (client-side decorations) windows, as well as gdk_window_set_functions and backdrop implementations.
