+Deprecated P2P messages
+-----------------------
+
+- BIP 61 reject messages are now deprecated. Reject messages have no use
+  case on the P2P network and are only logged for debugging by most network
+  nodes. Furthermore, they increase bandwidth and can be harmful for privacy
+  and security. It has been possible to disable BIP 61 messages since v0.17
+  with the `-enablebip61=0` option. BIP 61 messages will be disabled by default
+  in a future version, before being removed entirely.
