Hi Christo,
Other than the missing Docker artifacts (kafka and kafka-native), I also
noticed that some KS Jiras (recently included) seem to be missing from the
release notes (e.g., KAFKA-15307, KAFKA-19529).
Other than that, I did the following:
- checked the release notes
- checked maven artifacts containing 4.0.1
- built from sources (Java 17 and Scala 2.13.15)
- ran quick start
- tried basic produce/consume with classic and consumer protocol, and
groups upgrade/downgrade
- ran system tests, got only 2 failures on NetworkDegradeTest.test_latency,
but they passed locally.
- System tests results here:
https://confluent-open-source-kafka-branch-builder-system-test-results.s3-us-west-2.amazonaws.com/trunk/2025-08-27--002.920226bc-6e38-4a2f-add5-764067c6ae9d--1756305760--confluentinc--4.0--2968be954f/report.html
I'll hold off on voting until we sort out the pending docker/notes issues.
Thanks for running the release!
