If you're reading this, and are updating from release 16 or earlier:
RE-READ THE README.
Things have changed. Lots of things - pretty much all of them.
This will not work without you changing things in your configuration.
If you don't like this. Don't install this upgrade.
If you want HACS to stop bothering you to update - select version 16 specifically, and install that.
If you're updating from 2.2.0 or later. Go ahead. You're golden!
