   which are doing so may need some adjustments, since the addition of the
   message area changed the internal widget hierarchy.
 
-* GDK will now set all matching virtual modifiers in the state field of
-  key events. Depending on your X modifier map, this can lead to more bits
-  in the state field being set than before. If you are manually matching
-  key events against key/modifier combinations you should make sure that
-  you properly mask away irrelevant parts of the state field. The
-  gdk_keymap_map_virtual_modifiers() function can help with matching
-  against virtual modifiers.
+* GtkBuilder no longer sets the "name" property of widgets to the ID
+  attribute of the <object>. Use gtk_buildable_get_name() instead of
+  gtk_widget_get_name() to obtain the ID.
