I don't say that basic_publish_message should always maintain the lifetime by itself. The lifetime can be managed by outside code such as life_keeper as follows: https://github.com/redboltz/mqtt_cpp/blob/8f2fa503f11eb6b52b94b55727c7aecb2046b1fe/include/mqtt/endpoint.hpp#L2139 https://github.com/redboltz/mqtt_cpp/blob/8f2fa503f11eb6b52b94b55727c7aecb2046b1fe/include/mqtt/endpoint.hpp#L8652 It is good...

Yes but v3.1.1's unsuback is not error. I sum up as follows: |version|subscribe|unsubscribe|suback|unsuback| |---|---|---|---|---| |v3.1.1|x|x|x|- (no payload)| |v5|x|x|x|x| x: empty payload is protocol error.

Yes. The earlier version of mqtt_cpp use test.mosquitto.org for test. I added UUID prefix to topic and client id to avoid conflict. However, test.mosquitto.org is not good for CI. It...
