Does the moquette supports MQTT 5? (question)

[BigGitWorld]

Hello.
Does the latest version of Moquette (0.17) support MQTT version 5?

Looking into the code at class MQTTConnection it does not.

if (isNotProtocolVersion(msg, MqttVersion.MQTT_3_1) && isNotProtocolVersion(msg, MqttVersion.MQTT_3_1_1)) {
            LOG.warn("MQTT protocol version is not valid. CId: {}", clientId);
            abortConnection(CONNECTION_REFUSED_UNACCEPTABLE_PROTOCOL_VERSION);
            return PostOffice.RouteResult.failed(clientId);
        }

I have to find something else too. But testcontainers are too heavy.

Not yet, I'm working on pushing it in spare time, the version 0.18 is the target for MQTT5 support.
Keep an eye to #695 to check where we are.
