1.5.2: send() never rejects (status, error, scene, change report: resolves the topic or "" and reports the failure through the bridge's error event when listened to - 1.5.1 rejected, and an un-caught .send() killed the host on any broker hiccup); types ship (declaration: true, dist/*.d.ts tracked; addSupportedModes takes {value, modeResources}, ActionMapping payload optional, addHealthProp accepts EndpointHealth or the string); disconnect()/connect() re-binds devices to the new client; registerDevice returns the existing device on a duplicate endpointId (warning via the log hook, console.warn without one); ThermostatController discovery lists targetSetpoint and drops adaptiveRecoveryStatus; the UNSUPORTED INTERFACE TYPE stderr spam goes through the log hook. Examples: require("alex2node"), an error listener in each, EndpointHealth.OK, neutral endpoint ids, BlindControl reads correlationToken from the header, the thermostat reports Fahrenheit as Fahrenheit, ExamplePowerController is power-only again + new ExamplePowerControllerWithBrightness. readme (install from Forgejo, 1.5.2 changelog, table syntax), LICENSE (MIT); tests for the non-rejecting send, reconnect, duplicate, thermostat discovery and the shipped declaration signatures (8/8 on an in-process broker).
