 .. note::
    OpenStack Image service (glance) image IDs and ``file://`` links are also
    accepted.
 
+.. note::
+   Before the Xena release the parameters were called ``redfish_deploy_iso``
+   and ``redfish_rescue_iso`` accordingly. The old names are still supported
+   for backward compatibility.
+
 No customization is currently done to the image, so e.g.
 :doc:`/admin/dhcp-less` won't work. `Configuring an ESP image`_ is also
 unnecessary.
