- MQTT nodes failed to build: the topic map was renamed to talk in ports, but __slots__ still declared the old name, so every MQTT node raised AttributeError. Building one of each node type is now a test, since __slots__ makes this failure invisible until someone places the node. - Port names offer the messages already in play: everything published is worth reading, and an input nobody provides yet is worth publishing. A message only connects when both ends spell it the same way, so choosing beats typing. - Adding a port focuses its name field. - Dragging onto an input that already reads something offers the extra port as well as the replacement — an MQTT or InfluxDB node usually wants both. - The template's Item model, its routes, screens and table are gone.
