[tor-packagers] Tor 0.4.5.5-rc is released!

[Nick Mathewson]

We need to do one more release candidate to fit in a couple of
important fixes.  We hope this is the last one before stable, though.
Please check it out?

Testing this release in particular is pretty vital, since we plan to
backport the anti-DoS feature to other stable releases soon.
Additionally, we're planning to put out stable releases later this
week, if all goes well.

Here's the changelog:

Changes in version 0.4.5.5-rc - 2021-02-01
  Tor 0.4.5.5-rc is the third release candidate in its series. We're
  coming closer and closer to a stable release series. This release
  fixes an annoyance with address detection code, and somewhat mitigates
  an ongoing denial-of-service attack.

  We anticipate no more code changes between this and the stable
  release, though of course that could change.

  o Major feature (exit):
    - Re-entry into the network is now denied at the Exit level to all
      relays' ORPorts and authorities' ORPorts and DirPorts. This change
      should help mitgate a set of denial-of-service attacks. Closes
      ticket 2667.

  o Minor bugfixes (relay, configuration):
    - Don't attempt to discover our address (IPv4 or IPv6) if no ORPort
      for it can be found in the configuration. Fixes bug 40254; bugfix
      on 0.4.5.1-alpha.
