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.
