Hello Kafka users, developers and client-developers, This is the 3rd candidate for release of Apache Kafka 3.4.1.
This is a bugfix release with several fixes since the release of 3.4.0. A few of the major issues include: - core KAFKA-14644 <https://issues.apache.org/jira/browse/KAFKA-14644> Process should stop after failure in raft IO thread KAFKA-14946 <https://issues.apache.org/jira/browse/KAFKA-14946> KRaft controller node shutting down while renouncing leadership KAFKA-14887 <https://issues.apache.org/jira/browse/KAFKA-14887> ZK session timeout can cause broker to shutdown - client KAFKA-14639 <https://issues.apache.org/jira/browse/KAFKA-14639> Kafka CooperativeStickyAssignor revokes/assigns partition in one rebalance cycle - connect KAFKA-12558 <https://issues.apache.org/jira/browse/KAFKA-12558> MM2 may not sync partition offsets correctly KAFKA-14666 <https://issues.apache.org/jira/browse/KAFKA-14666> MM2 should translate consumer group offsets behind replication flow - stream KAFKA-14172 <https://issues.apache.org/jira/browse/KAFKA-14172> bug: State stores lose state when tasks are reassigned under EOS Release notes for the 3.4.1 release: https://home.apache.org/~showuon/kafka-3.4.1-rc2/RELEASE_NOTES.html *** Please download, test and vote by May 31, 2023 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/~showuon/kafka-3.4.1-rc2/ * Maven artifacts to be voted upon: https://repository.apache.org/content/groups/staging/org/apache/kafka/ * Javadoc: https://home.apache.org/~showuon/kafka-3.4.1-rc2/javadoc/ * Tag to be voted upon (off 3.4 branch) is the 3.4.1 tag: https://github.com/apache/kafka/releases/tag/3.4.1-rc2 * Documentation: (will be updated after released) https://kafka.apache.org/34/documentation.html * Protocol: (will be updated after released) https://kafka.apache.org/34/protocol.html The most recent build has had test failures. These all appear to be due to flakiness, but it would be nice if someone more familiar with the failed tests could confirm this. I may update this thread with passing build links if I can get one, or start a new release vote thread if test failures must be addressed beyond re-running builds until they pass. Unit/integration tests: https://ci-builds.apache.org/job/Kafka/job/kafka/job/3.4/138/ System tests: Will update the results later Hope this will be the final RC for v3.4.1! Thank you. Luke
