RTL_433 configuration: rtl_conf _file deprectiated?

I am trying to do a simple install of rtl_433 addon…and in the log I see this very confusing warning…and there is nothing in the documentation about migration:

[16:08:05] WARNING: rtl_433 now supports automatic configuration and multiple radios. The rtl_433_conf_file option is deprecated. See the documentation for migration instructions

This is mysterious…because I have to configure where the mqtt server is, etc.

What is the log talking about???

Did it work?
