Changes in version 0.3.3.1-alpha - 2018-01-??:
Blurb goes here
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
unused code path.
- The majority ot the channel unit tests have been rewritten and the
code coverage has now been raised to 83.6% for channel.c. Closes
ticket 23709.
- We've simplify a lot the channel subsystem by removing those
queues but also by removing a lot of unused code or dead code
around it. Overall this is a cleanup removing more than 1500 lines
of code overall and adding very little except for unit test.
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 Minor 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. 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, portability, experimental):
- Tor now ships with an optional implementation of one of its
smaller modules (protover.c) in the Rust programming language. To

Implements 23827.
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.
o Minor features (cleanup):
- Tor now deletes the CookieAuthFile and ExtORPortCookieAuthFile
when it stops. Closes ticket 23271.

o Minor features (fallback directory list):
- Avoid selecting fallbacks that change their IP addresses too
often. Select more fallbacks by ignoring the Guard flag, and
allowing lower cutoffs for the Running and V2Dir flags. Also allow
a lower bandwidth, and a higher number of fallbacks per operator
(5% of the list). Implements ticket 24785.
- Update the fallback whitelist and blacklist based on opt-ins and
relay changes. Closes tickets 22321, 24678, 22527, 24135,
and 24695.
o Minor features (fallback directory mirror configuration):
- Add a nickname to each fallback in a C comment. This makes it
