+ This was a bug introduced in 4.3.3, in whihch the table is changed from ets to mnesia

+ +* Log level for normal termination changed from info to debug [#6358] + +* Added config `retainer.stop_publish_clear_msg` to enable/disable empty message retained message publish [#6343]

+ e.g. messages from CoAP, LwM2M, Stomp, ExProto, when translated into MQTT message
+ properties such as protocol name, protocol version, username (if any) peer-host
