Tortoise Evolved: MQTT 5 Support in Tortoise MQTT Client

MQTT is a light-weight pub/sub protocol used for machine-to-machine communication, often used in IoT applications. Tortoise is an MQTT client for Elixir that started life as an MQTT 3.1.1 client and is being upgraded to MQTT 5.

Martin introduces MQTT, gives an overview of the new features in MQTT 5, and walks through how Tortoise is designed to make MQTT easy to work with in Elixir — and how MQTT 5 will influence that design.
