     The system assignment policies have been deprecated. The

+    ``identity:list_system_grants_for_group``, and
+    ``identity:check_system_grant_for_group`` policies now use
     ``role:reader and system_scope:all`` instead of
-    ``rule:admin_required``. The

-    ``identity:revoke_system_grant_for_user`` policies now use
