+Release notes for 3.18
+======================
+
+* The GtkListBox model support that was introduced in 3.16 has been
+  changed to no longer call gtk_widget_show_all on rows created by
+  the create_widget_func. You need to manage the visibility of child
+  widgets yourself in your create_widget_func.
+
+* The alpha component of foreground colors that are applied to
+  GtkCellRendererText is no longer ignored. If you don't want your
+  text to be translucent, use opaque colors.
