Hi Thomas, Thanks for the efficient feedback.
Regarding the suggestion of adding the release notes document, I agree with your point. Maybe we should adjust the vote template accordingly in the respective wiki to guide the following release processes. Regarding the performance regression, could you provide some more details for our better measurement or reproducing on our sides? E.g. I guess the topology only includes two vertexes source and sink? What is the parallelism for every vertex? The upstream shuffles data to the downstream via rebalance partitioner or other? The checkpoint mode is exactly-once with rocksDB state backend? The backpressure happened in this case? How much percentage regression in this case?

Generally, we carry forward the existing configuration and any change to default configuration values would impact the upgrade. Yes, since it is an incompatible change I would state it in the release notes. Thanks, Thomas BTW I found a performance regression while trying to upgrade another pipeline with this RC. It is a simple Kinesis to Kinesis job. Wasn't able to pin it down yet, symptoms include increased checkpoint alignment time.
