+Release notes for 3.6
+=====================
+
+* GtkIconInfo has changed from being a boxed type to a GObject. This
+  is technically an ABI change, but basically all existing code
+  will keep working if its used as a boxed type, and its not
+  possible to instantiate GtkIconInfos outside Gtk, so this is not
+  expected to be a big problem.
