Changes in version 0.4.4.4-rc - 2020-08-13
  Tor 0.4.4.4-rc is the first release candidate in its series. It fixes
  several bugs in previous versions, including some that caused annoying
  behavior for relay and bridge operators.

  o Minor features (security):
    - Channels using obsolete versions of the Tor link protocol are no
      longer allowed to circumvent address-canonicity checks. (This is
      only a minor issue, since such channels have no way to set ed25519
      keys, and therefore should always be rejected for circuits that
      specify ed25519 identities.) Closes ticket 40081.

  o Minor features (defense in depth):
    - Wipe more data from connection address fields before returning
      them to the memory heap. Closes ticket 6198.

  o Minor bugfixes (correctness, buffers):
    - Fix a correctness bug that could cause an assertion failure if we
      ever tried using the buf_move_all() function with an empty input
      buffer. As far as we know, no released versions of Tor do this.
      Fixes bug 40076; bugfix on 0.3.3.1-alpha.

  o Minor bugfixes (linux seccomp2 sandbox):
    - Fix startup crash with seccomp sandbox enabled when tor tries to
      open the data directory. Patch from Daniel Pinto. Fixes bug 40072;
      bugfix on 0.4.4.3-alpha-dev.

  o Minor bugfixes (onion service v3):
    - Remove a BUG() warning that could trigger in certain unlikely
      edge-cases. Fixes bug 34086; bugfix on 0.3.2.1-alpha.

  o Minor bugfixes (rate limiting, bridges, pluggable transports):
    - On a bridge, treat all connections from an ExtORPort as remote by
      default for the purposes of rate-limiting. Previously, bridges
      would treat the connection as local unless they explicitly
      received a "USERADDR" command. ExtORPort connections still count
      as local if there is a USERADDR command with an explicit local
      address. Fixes bug 33747; bugfix on 0.2.5.1-alpha.

  o Minor bugfixes (relay, self-testing):
    - When starting up as a relay, if we haven't been able to verify
      that we're reachable, only launch reachability tests at most once
      a minute. Previously, we had been launching tests up to once a
      second, which was needlessly noisy. Fixes bug 40083; bugfix
      on 0.2.8.1-alpha.

  o Minor bugfixes (testing):
    - When running the subsystem order check, use the Python binary
      configured with the PYTHON environment variable. Fixes bug 40095;
      bugfix on 0.4.4.1-alpha.

  o Minor bugfixes (windows):
    - Fix a bug that prevented Tor from starting if its log file grew
      above 2GB. Fixes bug 31036; bugfix on 0.2.1.8-alpha.
