# Changelog

## 7.0.1

- Fix regression where clients with `/` in their client id (e.g. `govee2mqtt`) were rejected with "ACL denying access to client with dangerous client id" after the mosquitto 2.1 upgrade ([#4564](https://github.com/home-assistant/addons/issues/4564))

## 7.0.0

- Remove unsupported architectures (armhf, armv7, i386)

# The addon's ACL file does not use pattern substitution (%c/%u), so
