Tortoise Evolved; MQTT 5 support in Tortoise MQTT Client
summary
Tortoise is an Elixir MQTT client that started as MQTT 3.1.1 and is evolving to MQTT 5; a work-in-progress branch implements MQTT 5 user properties, an enhanced auth (auth flow state) for challenge/response, and extra callbacks so brokers can negotiate things like max message size. It already handles QoS 0/1/2 semantics, keeps sessions alive and auto-reconnects (same client ID takes over previous session), stores in-flight messages, pings automatically, and is in production (smartrend and others).
