+3.31.91 – February 20, 2019
+=============================
+
+The user can now display the final state of the game,
+by undoing after (or during) the final animation; and
+this animation is also more reliable (it was randomly
+failing). Also, the Adwaita (blue) theme that is used
+as default already if the user changes GNOME settings
+to always use dark theme is now also default when the
+Gtk theme is Adwaita-dark. Other than that, many code cleanings and various small fixes (highlight, focus).
