3 - When a relay is extending a circuit to a bridge, it needs to send a
4 NETINFO cell, even when the bridge hasn't sent an AUTH_CHALLENGE
5 cell. Fixes bug 9546; bugfix on 0.2.3.6-alpha.
7 - Bridges send AUTH_CHALLENGE cells during their handshakes; previously
8 they did not, which prevented relays from successfully connecting
9 to a bridge for self-test or bandwidth testing. Fixes bug 9546;
10 bugfix on 0.2.3.6-alpha.
