+================================
+
+Due to significant security concerns, the *reuse_address* parameter of
+:meth:`asyncio.loop.create_datagram_endpoint` is no longer supported. This is
+because of the behavior of the socket option ``SO_REUSEADDR`` in UDP. For more
+details, see the documentation for ``loop.create_datagram_endpoint()``.
