- Web address now uses the port + 1 from the API address port directly. - Remove ratelimiting, ratelimiting will be achieved if necessary through iptables. - Remove json flag, not needed anymore. - Remove anonymous flag, server will be no more anonymous for play.minio.io we will use demo credentials.
