Hi Christo, I ran the following validations on the RC2: - spot checked release notes - build from src (Java 21 and Scala 2.13.15) - run unit test - only failure is the known MetadataSchemaCheckerToolTest. testVerifyEvolutionGit() tracked here https://issues.apache.org/jira/browse/KAFKA-18973 - run integration test - all pass after several runs - followed quickstart with basic consume/produce - basic consume with classic and consumer groups, mixed groups and online upgrade/downgrade - download and run both docker images. - run basic produce consume using apache/kafka:4.0.1-rc2 - run system tests, just 2 failures on network_degrade_test but they pass locally (report here https://confluent-open-source-kafka-branch-builder-system-test-results.s3-us-west-2.amazonaws.com/trunk/2025-09-11--002.7316dfbf-9dc4-4d20-850d-fe7d729cdcc5--1757616334--confluentinc--4.0--618d5155c7/report.html )
+1 (non-binding) Thanks for running this release!
