+    The pulse-module function ``qiskit.pulse.utils.deprecate_functionality`` is
+    deprecated and will be removed in a future release.  This was a primarily
+    internal-only function.  The same functionality is supplied by
+    ``qiskit.utils.deprecate_function``, which should be used instead.
