+=== Upgrading from 2.41.0
+
+* The broker was always meant to scan MQTT sessions every `5000` milliseconds,
but due to a bug it was doing so every `500` milliseconds instead.
+This has been fixed via
https://issues.apache.org/jira/browse/ARTEMIS-5202[ARTEMIS-5202].
+Since this is technically changing the default behavior of the broker it is
being enumerated here for clarity.
+Keep in mind that this is configurable via the
xref:mqtt.adoc#automatic-subscription-clean-up[`mqtt-session-scan-interval`]
parameter in `broker.xml`.
