Hi David, Thanks for this next release candidate.
Maybe I'm missing something, but I was trying to test out some of the changes that Jose provided, by configuring a static quorum (kraft.version=0) and I seem to be unable to do so. I set controller.quorum.voters=1@localhost:9093 as per how it looked in 3.9 (with no controller.quorum.bootstrap.servers, but no matter what I do it says "Cannot set kraft.version to 0 if KIP-853 configuration is present. Try removing the --feature flag for kraft.version." Can someone help me out here? The documentation says: > The static versus dynamic nature of the quorum is determined at the time of formatting. Specifically, the quorum will be formatted as dynamic if controller.quorum.voters is *not* present, and if the software version is Apache Kafka 3.9 or newer. If you have followed the instructions earlier in this document, you will get a dynamic quorum. But this seems incorrect. I'm hoping I'm just misunderstanding the documentation and not that there is another issue.
