+Release 3.10
+------------
+
+1. The positional argument ``<snapshot-name>`` of the ``volume snapshot create``
+   command is no longer optional.
+
+   Previously when the ``--volume`` option was
+   present ``<snapshot-name>`` defaulted to the ``--volume`` value.  When the
+   ``--volume`` option is not present now it defaults to the value of
+   ``<snapshot-name>``.
