1.1.0: begin(username, password, rootTopic) - the library signature now matches every example, the readme and the website (as published since 2024 no sketch could authenticate: the 64-hex password became the MQTT username). Discovery answers go out over MQTT directly, every device, resumed from loop() under heap pressure within the backend's 5 s window, instead of the 5-slot HTTP queue that silently dropped the rest (which the backend's reconcile then deleted from Alexa). JSON aligned with Alexa / alex2node: event.payload present, ActionMapping payload an object, semantics only when a capability has mappings. Pointer-stable device/capability containers (std::deque), the MQTT payload is copied by length before parsing (no write past the buffer), fragmented directive ids are ignored (a Discover is answered on its first fragment), deprecated ArduinoJson 7 calls replaced, credential Serial prints removed, ESP32 include guards (untested; the ESP8266 is the target). Examples: WIFI_PASSWORD, LED_BUILTIN fallback, string+int print fixes. library.json + library.properties restored (1.1.0; AsyncMqttClient, ArduinoJson 7, ESP Async TCP), LICENSE (MIT), a real keywords.txt, .gitattributes text=auto eol=lf (tree normalised to LF). readme: Forgejo URLs, platformio.ini snippet, Library Manager install, begin() order, INTERIOR_BLIND for blinds, 1.1.0 changelog. All five examples compile warning-free for d1_mini (PlatformIO 6.2, espressif8266) on pve-B450.
