This release focusses on improving how the consumer shuts down, both normally and after an error, e.g. due to an ACL change. Again many thanks to @acrow for these amazing contributions. The consumer now shuts down faster by processing less already queued items, and it now properly shuts down after client errors that previously caused a zombie like hang. As a bonus, the unit tests now complete in 1m 35 instead of 3m 30 on a fast laptop.

Note: the kafka-client dependency is upgraded from 4.3.0 to 4.3.1.
