-  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 features (testing):
-    - 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.

-  o Minor features (testing):
-    - 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.
-    - Relays on testing networks no longer rate-limit how frequently
-      they are willing to report new bandwidth measurements. Part of a fix

@@ -1,6 +0,0 @@
-  o Minor bugfix (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 can thus lead to wrongly
-      flagging many relays and thus affecting circuit building path selection.
-      Fixes bug 40434; bugfix on 0.2.0.13-alpha.

-  o Minor bugfixes (onion service, TROVE-2021-008):
-    - Only log once any v2 access attempts in order to not pollute the logs
-      with warnings and avoid recording the times on disk when v2 access was
-      attempted. Important to note that the onion address was _never_ logged.
-      That is a Low security issue. Fixes bug 40474; bugfix on 0.4.5.8.

-  o Major bugfixes (relay, overload state):
-    - Report the general overload state for DNS timeout errors only if X% of all
-      DNS queries over Y seconds are errors. Before that, it only took 1 timeout
-      to report the overload state which was just too low of a threshold. The X
-      and Y values are 1% and 10 minutes respectively but they are also
-      controlled by consensus parameters. Fixes bug 40491; bugfix on
