Reduce STDERR logging to only WARNING and above.

Browse Source 
INFO logs are now only viewable in the log file, which is not written
by default. A new command line option --log-file can be used to control
where the log file is written.

INFO logs can be written to STDERR if --log-all-to-stderr is passed.
