Patch (Revision 1)
Version 0.9.0 brings no functional changes except the switch to dreaded Gtk3 which I'd much rather avoid. I will, however, provide an option to build current version against Gtk3, as the changes are minor and mechanical.
The truth is that GTK 2 is on it's way out. With the release of GTK 4/GNOME 40, GTK 2 is end of life.
See: "It does mean, however, that GTK 2 has reached the end of its life."
