2.0.4 accidently changed the MAC address handling and to reduce confusion it stuck with it moving forward.
In regard to the HTTP commands, all of the controller’s /v? functions are going away or are gone already. However, the commands to change options/stations are still present and the same, is there any particular command that’s not working?
The upcoming, 2.1.0 firmware, will have a few more changes and the documentation will be updated for it.
