 Overview of changes from GLib 2.31.2 to 2.31.4
 ==============================================
 
-* Menu support has been added to GApplication. Menus
-  are exported on the bus, alongside the actions that are
-  already there.
+* EXPERIMENTAL: Menu support has been added to GApplication.  Menus
+  are exported on the bus, alongside the actions that are already there.
+  There have also been many related improvements to action group
+  functionality.
+
+  These new APIs are subject to changes in the coming releases.  In
+  particular, it seems somewhat likely that the APIs for registering
+  menubars may change in order to accommodate windows with different
+  types of menubars.
+
+* GDBusConnection previously directly dispatched destroy notifies when
+  unregistering objects if the current main context was the same context
+  the object was exported on.  It now unconditionally dispatches these
+  through an idle on the context.
 
 * Clean up Requires in pc files. Linking against GIO no
   longer drags in gmodule. This may require dependency
