Description :
Mosquitto is an open source message broker that implements the MQ Telemetry
Transport protocol version 3.1 and 3.1.1 MQTT provides a lightweight method
of carrying out messaging using a publish/subscribe model. This makes it
suitable for "machine to machine" messaging such as with low power sensors
or mobile devices such as phones, embedded computers or micro-controllers
like the Arduino.

Mosquitto with a topic that begins with $, but is not $SYS, then an assert that
should be unreachable is triggered and Mosquitto will exit. Broker: * Elevate
log level to warning for situation when socket limit is hit. * Remove
requirement to use `user root` in snap package config files. * Fix retained
messages not sent by bridges on outgoing topics at the first connection. *
Documentation fixes. * Fix duplicate clients being added to by_id hash before
the old client was removed. * Fix Windows version not starting if include_dir
did not contain any files. Build: * Various fixes to ease building. Further
