  Tor 0.3.1.6-rc fixes a few small bugs and annoyances in the 0.3.1

  release series.

  This is the first release candidate in the Tor 0.3.1 series. If we

  find no new bugs or regressions here, the first stable 0.3.1 release

  will be nearly identical to it.

  o Minor features (directory authority):

    - Improve the message that authorities report to relays when

      the RSA/Ed25519 key pair they present conflicts with a previously

    - Improve the message that authorities report to relays when the

      RSA/Ed25519 key pair they present conflicts with a previously

      pinned key. Closes ticket 22348.

  o Minor features (geoip):

      directory cache. Fixes bug 23139; bugfix on 0.3.1.1-alpha.

  o Minor bugfixes (hidden service):

    - A service is allowed to open a maximum number of circuits for a specific

      period of time. That value was lower than it should be (8 vs 12) in the

      normal case of 3 introduction points. Fixes bug 22159; bugfix on

      0.3.0.5-rc.

    - Fix a BUG alert during HSv3 descriptor decoding that could trigger with a

      specially crafted descriptor. Fixes bug 23233; bugfix on 0.3.0.1-alpha.

      Bug found by "haxxpop".

    - Rate limit the log if we ever go above the maximum number of allowed

      intro circuits. Fixes bug 22159; bugfix on 0.3.1.1-alpha.

  o Minor bugfixes (logging, relay):

    - Remove a log_warn() that has been forgotten when an introduction point

      successfully established a hidden service prop224 circuit with a client.

    - Three other log_warn() for an introduction point have been changed to

      protocol warning because they can be failure from the network and are

      not relevant to the operator. Fixes bug 23078; bugfix on

      0.3.0.1-alpha and 0.3.0.2-alpha.

  o Minor bugfixes (robustness, error handling):

    - Improve our handling of the cases where OpenSSL encounters a

      memory error while encoding keys and certificates. We haven't

      observed these happening in the wild, but if they do happen,

      we now detect and respond better. Fixes bug 19418; bugfix

      on all versions of Tor. Reported by Guido Vranken.

  o Minor bugfixes (stability):

    - Avoid crashing on double-free when unable to load or process

      an included file. Fixes bug 23155; bugfix on 0.3.1.1-alpha.

  o Minor bugfixes (testing):

    - Fix an undersized buffer in test-memwipe.c. Fixes bug 23291; bugfix on

    - Port the hs_ntor handshake test to work correctly with recent

      versions of the pysha3 module. Fixes bug 23071; bugfix on

      0.3.1.1-alpha.

      on 0.3.1.1-alpha.

  o Minor bugfixes (Windows service):

    - When running as a Windows service, set the ID of the main thread

      correctly. Failure to do so made us fail to send log messages

      to the controller in 0.2.1.16-rc, slowed down controller

      event delivery in 0.2.7.3-rc and later, and crash with an assertion

      correctly. Failure to do so made us fail to send log messages to
