+// Done:
+// Enable MQTT over SSL as per https://github.com/debsahu/ESP_MQTT_Secure/tree/master/ESP8266_MQTT_SSL/Arduino/ESP8266_PubSubClient_SSL
+// Cooperative multitasking: Use timers always. Avoid delays where they can be avoided.
+// Restructure mqtt topics a bit (report back with unique names for multiple fx lights, for instance)
+// Implement versioning so that new firmware can be done OTA
+
+// Todo:
+// Split the wifi and mqtt code in order to support http interface
+// Stay on the lookout for watchdog crashes, see also https://www.sigmdel.ca/michel/program/esp8266/arduino/watchdogs_en.html#ESP8266_WDT_RECOV
+// Keeps crashing after a few days. Dunno why. https://www.pieterverhees.nl/sparklesagarbage/esp8266/130-difference-between-esp-reset-and-esp-restart
+// More on this subject https://github.com/esp8266/Arduino/issues/1017
+// Implement more visual effects
+// Implement speed controls for the visual effects
+// Implement OTA https://www.bakke.online/index.php/2017/06/02/self-updating-ota-firmware-for-esp8266/
+// Refactoring sources: https://www.arduinolibraries.info/architectures/esp8266
+// Refactor String usage to minimize heap pollution. https://cpp4arduino.com/2018/11/21/eight-tips-to-use-the-string-class-efficiently.html

+// Version history:
+// v12: Refactored inbound commands to hook in to the modules (module_message function), completed assimilation of (never-published) Moon_Connected sketch
+// v11: Simplified scheduler, back to cooperative looping
+// v10: First 'production' run. MQTT over TLS, but no OTA support.
