Hi Konstantine, Thanks for running the release
I ran the following checks: - PGP Signatures used to sign the release artifacts - Validation of Release Artifacts Cryptographic Hashes (ASC MD5 SHA1 SHA512) - Validation of Kafka Source and Tests - Validation of Kafka Site Documentation - Manual Check of Javadocs - Validation of Cluster Setup for KRaft and Legacy Modes *+1 from me (non-binding)* To encourage other community members to participate in the release candidate validations and voting, I have set up the following resource as part of the work for KAFKA-9861 It is a set of scripts and Docker images that allows community members to run local validations in a consistent manner. https://github.com/izzyacademy/apache-kafka-release-party Please take a look at the resource and share any feedback that you may have. I plan to create a video tutorial that walks community members through how it can be used soon.
