+The ``high-availability`` argument is a list which currently always comprises
+one element. There are plans to extend the HA implementation to facilitate
+multiple HA relationships for a single server instance. In that case, the
+returned list will comprise more elements, each describing the status of
+a different relationship in which the server participates. Currently, it
+is only one status.
+
+.. note::
+
+   In Kea 1.7.8 an incompatible change was introduced to the syntax of the
+   ``status-get`` response. Previously, the HA status for a single relationship
+   was returned within the ``arguments`` map. Currently, the returned status
+   is enclosed in the list as described above. Any existing code relying on the
+   previous syntax must be updated to work with the new Kea versions.

 The ``ha-servers`` map contains two structures: ``local`` and ``remote``. The former
 contains the status information of the server which received the command. The
