+     - Clusters bootstrapped with ``snap-openstack`` versions earlier than 
+       **rev998** will continue to experience intermittent API failures (for up 
+       to 5 minutes) when a control node becomes unavailable. A known 
+       `k8s charm limitation <https://charmhub.io/k8s/configurations#kube-apiserver-extra-args>`_ 
+       restricts updates on active deployments, meaning this issue cannot be 
+       fixed on clusters deployed prior to this revision.
