The most recent build has had test failures. These all appear to be due to
flakiness, but it would be nice if someone more familiar with the failed
tests could confirm this. I may update this thread with passing build links
if I can get one, or start a new release vote thread if test failures must
be addressed beyond re-running builds until they pass.

Unit/integration tests:
https://ci-builds.apache.org/job/Kafka/job/kafka/job/3.4/138/

System tests:
Will update the results later

Hope this will be the final RC for v3.4.1!

Thank you.
Luke
