-Changes in version 0.4.7.1-alpha - 2021-09-17
-  This version is the first alpha release of the 0.4.7.x series. One
-  major feature is Vanguards Lite, from proposal 333, to help mitigate
-  guard discovery attacks against onion services. It also includes
-  numerous bugfixes.
-
-  o Major features (Proposal 332, onion services, guard selection algorithm):
-    - Clients and onion services now choose four long-lived "layer 2"
-      guard relays for use as the middle hop in all onion circuits.
-      These relays are kept in place for a randomized duration averaging
-      1 week. This mitigates guard discovery attacks against clients and
-      short-lived onion services such as OnionShare. Long-lived onion
-      services that need high security should still use the Vanguards
-      addon (https://github.com/mikeperry-tor/vanguards). Closes ticket
-      40363; implements proposal 333.
-
-  o Minor features (bridge testing support):
-    - Let external bridge reachability testing tools discard cached
-      bridge descriptors when setting new bridges, so they can be sure
-      to get a clean reachability test. Implements ticket 40209.
-
-  o Minor features (fuzzing):
-    - When building with --enable-libfuzzer, use a set of compiler flags
-      that works with more recent versions of the library. Previously we
-      were using a set of flags from 2017. Closes ticket 40407.
-
-  o Minor features (testing configuration):
-    - When TestingTorNetwork is enabled, skip the permissions check on
-      hidden service directories. Closes ticket 40338.
-    - On a testing network, relays can now use the
-      TestingMinTimeToReportBandwidth option to change the smallest
-      amount of time over which they're willing to report their observed
-      maximum bandwidth. Previously, this was fixed at 1 day. For
-      safety, values under 2 hours are only supported on testing
-      networks. Part of a fix for ticket 40337.
-    - Relays on testing networks no longer rate-limit how frequently
-      they are willing to report new bandwidth measurements. Part of a
-      fix for ticket 40337.
-    - Relays on testing networks now report their observed bandwidths
-      immediately from startup. Previously, they waited until they had
-      been running for a full day. Closes ticket 40337.
-
-  o Minor bugfixes (circuit padding):
-    - Don't send STOP circuit padding cells when the other side has
-      already shut down the corresponding padding machine. Fixes bug
-      40435; bugfix on 0.4.0.1-alpha.
-
-  o Minor bugfixes (compatibility):
-    - Fix compatibility with the most recent Libevent versions, which no
-      longer have an evdns_set_random_bytes() function. Because this
-      function has been a no-op since Libevent 2.0.4-alpha, it is safe
-      for us to just stop calling it. Fixes bug 40371; bugfix
-      on 0.2.1.7-alpha.
-
-  o Minor bugfixes (control, sandbox):
-    - Allows the control command SAVECONF to succeed when the seccomp
-      sandbox is enabled. Makes SAVECONF keep only one backup file, to
-      simplify implementation. Fixes bug 40317; bugfix on 0.2.5.4-alpha.
-      Patch by Daniel Pinto.
-
-  o Minor bugfixes (heartbeat):
-    - Adjust the heartbeat log message about distinct clients to
-      consider the HeartbeatPeriod rather than a flat 6-hour delay.
-      Fixes bug 40330; bugfix on 0.2.6.3-alpha.
-
-  o Minor bugfixes (logging, relay):
-    - Add spaces between the "and" when logging the "Your server has not
-      managed to confirm reachability for its" on dual-stack relays.
-      Fixes bug 40453; bugfix on 0.4.5.1-alpha. Patch by Neel Chauhan.
-
-  o Minor bugfixes (onion service):
-    - Do not flag an HSDir as non-running in case the descriptor upload
-      or fetch fails. An onion service closes pending directory
-      connections before uploading a new descriptor which leads to
-      wrongly flagging many relays and thus affecting circuit path
-      selection. Fixes bug 40434; bugfix on 0.2.0.13-alpha.
-
-  o Minor bugfixes (statistics):
-    - Fix a fencepost issue when we check stability_last_downrated where
-      we called rep_hist_downrate_old_runs() twice. Fixes bug 40394;
-      bugfix on 0.2.0.5-alpha. Patch by Neel Chauhan.
-
-  o Minor bugfixes (tests):
-    - Fix a bug that prevented some tests from running with the correct
-      names. Fixes bug 40365; bugfix on 0.4.3.1-alpha.
-
-  o Documentation:
-    - Add links to original tor design paper and anonbib to
-      docs/HACKING/README.1st.md. Closes ticket 33742. Patch from
-      Emily Bones.
-    - Describe the "fingerprint-ed25519" file in the tor.1 man page.

-
-  o Major bugfixes (cryptography, security):
-    - Resolve an assertion failure caused by a behavior mismatch between
-      our batch-signature verification code and our single-signature
-      verification code. This assertion failure could be triggered
-      remotely, leading to a denial of service attack. We fix this issue
-      by disabling batch verification. Fixes bug 40078; bugfix on

-
-  o Minor bugfixes (timekeeping):
-    - Calculate the time of day correctly on systems where the time_t
-      type includes leap seconds. (This is not the case on most
-      operating systems, but on those where it occurs, our tor_timegm
-      function did not correctly invert the system's gmtime function,
-      which could result in assertion failures when calculating voting
-      schedules.) Fixes bug 40383; bugfix on 0.2.0.3-alpha.
