+ o Minor bugfixes (logging):
+ - Avoid a spurious log message about missing subprotocol versions, when
+ the consensus that we're reading from is older than the current
+ release. . Previously we had made this message nonfatal in this case,
+ but in practice, it is never relevant when the consensus is older than
+ the current release. Fixes bug 40281; bugfix on 0.4.0.1-alpha.

+ o Minor bugfixes (relay):

+ to 0 and AssumeReachable is set to 1. This is to support the use case of a

+ Technically, we stopped supporting this subprotocol back in
+ 0.4.5.1-alpha, but we needed to wait for the authorities to stop
+ listing it as "required" before we can drop support. Closes ticket
+ 40221.
