Hi Lianet, I am a +1 (non-binding) on this release.
At LittleHorse we did extensive soaks of Kafka Streams with 4.1.1 RC2 and did not find any regression bugs. We did find this: https://issues.apache.org/jira/browse/KAFKA-19853 but it appears to be an old bug since the StateUpdater was first enabled by default (3.9.0) and we verified that it is present on 4.0.x.
