+               ServicesChanged(array{object, dict}, array{object})
+
+                       Signals a list of services that have been changed
+                       via the first array. And a list of service that
+                       have been removed via the second array.
+
+                       The list of added services is sorted. The dictionary
+                       with the properties might be empty in case none of
+                       the properties have changed. Or only contains the
+                       properties that have changed.
+
+                       For newly added services the whole set of properties
+                       will be present.
+
+                       The list of removed services can be empty.
+
+                       This signal will only be triggered when the sort
+                       order of the service list or the number of services
+                       changes. It will not be emitted if only a property
+                       of the service object changes. For that it is
+                       required to watch the PropertyChanged signal of
+                       the service object.
