  o Major features (Onion Services):
    - Provide torrc options to pin the second and third hops of onion service
      circuits to a list of nodes. The option HSLayer2Guards pins the second hop,
      and the option HSLayer3Guards pins the third hop. Closes ticket 13837.
Implement layer 2 and layer 3 guard pinning via torrc. Block circuit canibalization when HSRendezvousMiddleNodes is active. Also make it apply to all HS circuits, not just rends. 2017-12-22 06:43:44 +01:00			`o Major features (Onion Services):`
