MQTT Binding (v1.11) Getting Started 101

I’m talking about the github release page or the post on the website where the changes are linked.
Mqtt got a sucessor, which although mqtt1 and mqtt2 can coexist, will automatically uninstall mqtt1.
So your old configuration will definitely not work anymore before you re-install mqtt1. mqtt2 works
totally different and would require you to perform a migration.
