Recently the autoupdater contained a case statement to distinguish
between TP-Link WDR3600 and TP-Link WDR4300. This was left over from
previous development versions of autoupdater that relied on the board
name instead of the model. It is thus no longer needed and be removed
safely.
It is now possible to specific multiple branches like this:
config branch stable
option url ...
list pubkey ...
...
config branch testing
...
and select one in autoupdater.settings:
config autoupdater settings
option branch "stable"
