net-mqtt v0.2.4.1 Release Notes
-
🔗 Link QoS2 completion thread on subscriber.
👻 An exception from a subscriber callback could be silently dropped without completing the handshake which would then cause the MQTT broker to just stop sending messages to the subscriber. Unfortunately, the broker (at least mosquitto) still responds to pings and doesn't give any useful notification that it's no longer sending messages.
