[warn] Unrecognized BridgeDistribution value "settings". I'll assume you know what you are doing...

BridgeDistribution settings
seems to be recognized now because my new bridge ended up in the settings
bucket.
The fix may be as easy as adding settings
to the list of recognized strings in tor.
Someone should maybe checkout the other new values at https://bridges.torproject.org/info as well.
