 ### Enhancements
 
-* `'federation disable_tls_peer_verification_for_all_upstreams'` 
+* `federation disable_tls_peer_verification_for_all_upstreams` is a new command that disables TLS peer verification
+  for all federation upstreams.

+  if [peer verification](https://www.rabbitmq.com/docs/ssl#peer-verification) was enabled prematurely.
