+[[reporting_plugin]]
+=== Reporting plugin added new validation for protocol
+
+*Details:* The Reporting plugin added new validation for protocol strings in Network Policy configurations.
+
+*Impact*: See <<reporting-network-policy, Restrict requests with a Reporting network policy>>.
+If the kibana.yml has a Reporting network policy before upgrade,
+the protocol strings must end with a colon. Otherwise, config validation
+will fail and Kibana will not start.
