Changes in version 0.3.3.1-alpha - 2018-01-??:
Blurb goes here
o Major feature (channel):
o Code simplification and refactoring (channels):
- Remove the incoming and outgoing channel queues. The reason to do
so was due to the fact that they were always empty meaning never
used but still looked at in our fast path. Bottom line, it was an

onion services. Closes ticket 20699.
o Major features (Onion Services):
o Major features (onion services, security):
- 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.
o Major features (relay):

- Implement an option, ReducedExitPolicy, to allow an Tor exit relay
operator to use a more reasonable ("reduced") exit policy, rather
than the default one. Closes ticket 13605. Patch from Neel Chauhan.
operator to use a more reasonable ("reduced") exit policy, rather than
the default one. If you want to run an exit node without thinking too
hard about which ports to allow, this one is for you. Closes ticket
13605. Patch from Neel Chauhan.
o Major features (Rust experimentation):

- Tor now ships with an optional implementation of one of its
smaller modules (protover.c) in the Rust programming language. To
try it out, install a Rust build environment, and configure Tor

o Major features (storage, configuration):
- Users can choose to store cached directory documents somewhere
other than the DataDirectory by using the CacheDirectory option.
Similarly, the storage location for relay's keys can be overridden
with the KeyDirectory option. Closes ticket 22703.
o Major features (v3 onion services):
o Major features (v3 onion services, ipv6):
- When v3 onion service clients send introduce cells, include the
IPv6 address of the rendezvous point, if it has one. v3 onion
services running 0.3.2 ignore IPv6 addresses. In future Tor

o Major bugfixes (onion services):
o Major bugfixes (onion services, retry behavior):
- Fix an "off by 2" error in counting rendezvous failures on the
onion service side. While we thought we would stop the rendezvous
attempt after one failed circuit, we were actually making three
circuit attempts before giving up. Now switch to a default of 2,
and allow the consensus parameter "hs_service_max_rdv_failures" to
override. Fixes bug 24895; bugfix on 0.0.6.
- New-style (v3) onion services now obey the "max rendezvous circuit
attempts" logic. Previously they would make as many rendezvous
circuit attempts as they could fit in the MAX_REND_TIMEOUT second
window before giving up. Fixes bug 24894; bugfix on 0.3.2.1-alpha.

Implements 23827.
o Minor features (API, embedding):
o Minor features (embedding):
- Tor can now start with a preauthenticated control connection
created by the process that launched it. This feature is meant for
use by programs that want to launch and manage a Tor process
without allowing other programs to manage it as well. For more
information, see the __OwningControllerFD option documented in
control-spec.txt. Closes ticket 23900.
- On most errors that would cause Tor to exit, it now tries to
return from the tor_main() function, rather than calling the
system exit() function. Most users won't notice a difference here,
but it should make a significant difference on platforms that try
to run Tor inside a separate thread: they should now be able to
survive Tor's exit conditions rather than having Tor shut down the
entire process. Closes ticket 23848.
- Applications that want to embed Tor can now tell Tor not to
register any of its own POSIX signal handlers, using the
__DisableSignalHandlers option. This option is not meant for
general use. Closes ticket 24588.
