+    The image-list call to the Images v2 API now recognizes a ``protected``
+    query-string parameter.  This parameter accepts only two values: either
+    ``true`` or ``false``.  The filter is case-sensitive.  Any other value
+    will result in a 400 response to the request.  See the `protected filter
+    specification`_ document for details.
