commit 4c73e6dfb93ac216c8e1d68c88e7499860516f88 Author: David Fifield <david(a)bamsoftware.com> Date: Fri Sep 20 01:59:22 2013 -0700 Just include outermost transports in facilitator responses. This is in contradiction to what I proposed in https://trac.torproject.org/projects/tor/ticket/9349#comment:20.
