- Allow users to run regular relays. In addition to that users will be able to turn them into bridge relays. Like before, by default, relaying is enabled and the relay type bridge relay. - Show obfs3/4 transport ports as needing firewall port forwarding only if bridge relay is enabled. - Remove pluggable transports configuration from configuration when bridge rely is disabled. - Improve description message for relays and bridge relays.
