+Rewritten the support for multiple-format Drag'n'Drop and
+clipboard under both GTK and MSW. There are probably some
+problems here and there left.
+
+wxListBox and wxChoice can now handle only either void
+client data (which it will not delete on destruction) or
+client data of the wxClientData type (which it will delete),
+instead of both at the same time. The same will happen
+to wxComboBox some time. Also, wxListBox can now sort its
+items.
