  o Major bugfixes (mainloop, bootstrap):
    - Make sure Tor bootstraps and works properly if only the ControlPort is
      set. Prior to this fix, Tor would only bootstrap with at least a client
      port being set (Socks, Trans, NATD, DNS or HTTPTunnel port). Fixes bug
      27849; bugfix on 0.3.4.1-alpha.
