Hey folks, we found a couple of blockers with RC1 and have fixed them in the latest release candidate, RC2.
The major features of this release include: * KIP-881: Rack-aware Partition Assignment for Kafka Consumers <https://cwiki.apache.org/confluence/display/KAFKA/KIP-881%3A+Rack-aware+Partition+Assignment+for+Kafka+Consumers> * KIP-876: Time based cluster metadata snapshots <https://cwiki.apache.org/confluence/display/KAFKA/KIP-876%3A+Time+based+cluster+metadata+snapshots> * KIP-787: MM2 manage Kafka resources with custom Admin implementation. <https://cwiki.apache.org/confluence/pages/viewpage.action?pageId=191335620> * KIP-866 ZooKeeper to KRaft Migration <https://cwiki.apache.org/confluence/display/KAFKA/KIP-866+ZooKeeper+to+KRaft+Migration> (Early Access) Release notes for the 3.4.0 release: https://home.apache.org/~davidarthur/kafka-3.4.0-rc2/RELEASE_NOTES.html Please download, test and vote by Friday, February 3, 5pm PT --- Kafka's KEYS file containing PGP keys we use to sign the release: https://kafka.apache.org/KEYS * Release artifacts to be voted upon (source and binary): https://home.apache.org/~davidarthur/kafka-3.4.0-rc2/ * Maven artifacts to be voted upon: https://repository.apache.org/content/groups/staging/org/apache/kafka/ * Javadoc: https://home.apache.org/~davidarthur/kafka-3.4.0-rc2/javadoc/ * Tag to be voted upon (off 3.4 branch) is the 3.4.0 tag: https://github.com/apache/kafka/releases/tag/3.4.0-rc2 * Documentation: https://kafka.apache.org/34/documentation.html * Protocol: https://kafka.apache.org/34/protocol.html --- Test results: We haven't had a 100% passing build, but the latest system test run looks pretty good: http://confluent-kafka-system-test-results.s3-us-west-2.amazonaws.com/3.4/2023-01-31--001.system-test-kafka-3.4--1675184554--confluentinc--3.4--ef3f5bd834/report.html Here are the Jenkins test runs for 3.4: https://ci-builds.apache.org/job/Kafka/job/kafka/job/3.4/. We will continue trying to diagnose the flaky test failures as the release continues. I do not expect that any of these test failures are blockers for the release. Thanks! David Arthur
