[feat] MQTTV5 support. Home assistant dropping v3.1

[carefulcomputer]

Home assistant will deprecate mqttv3.1 and only support v5 starting next year. That means that current aedes broker (which support upto 3.1) will no longer be compatible with home assistant. That will be shame since I have used aedes for last decade and will be forced to switch to another broker. I really love aedes for it's simplicity and reliability.
Is there any plan to support v5 ?

Are you sure Home Assistant will drop MQTT v3.1?
Reference to an official Home Assistant page would be nice.
I'm curious about their rationale and what exact v5 features they would require.

Kind regards,
Hans

Btw: Aedes supports MQTT 3.1 (protocol version 3) and MQTT 3.11 (protocol version 4). If Home Asssistant only drops MQTT 3.1 (protocol version 3) you can still use MQTT 3.11 (protocol version 4).

I got a message popup in latest home assistant upgrade that haas will not support 3.1 (or 4) starting next year.
here is official haas page https://www.home-assistant.io/integrations/mqtt/ and quote
"Home Assistant requires that your broker supports MQTT protocol version 5. Most MQTT brokers, like the official “Mosquitto broker” App will support MQTT protocol version 5."
