Hi Jiunn-Yang, Thanks for running the release. I verified 4.3.2-rc0 as follows:
Checksums (md5/sha1/sha512) and signatures of all artifacts, plus the staged kafka-clients Maven artifacts. Signed by 062C22C0F467AF9A02D512B5504473FAF80CBBCB, which is in KEYS. Source tarball matches the 4.3.2-rc0 tag (bc6c0af7). Shipped jar versions match the dependency bumps and LICENSE-binary. jline-remote-telnet is no longer shipped. Ran the full test suite from source with JDK 25. All passed; only a few known flaky tests needed a retry. Smoke tested the binary with JDK 25: KRaft broker, produce/consume, consumer group, Streams WordCount with the streams protocol, and Connect FileStreamSource. Ran produce/consume against both Docker images. I noticed that 4.3 has two commits after the RC tag (#23669 and #23627). Please double check whether they are intended for 4.3.2. +1 (binding) Thanks, Chia-Ping On 2026-09-29 12:22 UTC 黃竣陽 wrote: > Hello Kafka users, developers and client-developers, > > This is the first candidate for release of Apache Kafka 4.3.2. > > This is a bugfix release in 4.3 line. > > Release notes for the 4.3.2 release: > https://dist.apache.org/repos/dist/dev/kafka/4.3.2-rc0/RELEASE_NOTES.html > > Please download, test and vote by Friday, October 2nd, 9am PT > > Kafka's KEYS file containing PGP keys we use to sign the release: > https://downloads.apache.org/kafka/KEYS > > * Release artifacts to be voted upon (source and binary): > https://dist.apache.org/repos/dist/dev/kafka/4.3.2-rc0/ > > * Docker release artifacts to be voted upon: > apache/kafka:4.3.2-rc0 > <https://hub.docker.com/layers/apache/kafka/4.3.2-rc0/images/sha256-aad4e610fcbbb44b142dfe89c5d1e62262d0323bba68b46092853d3ee961c719> > apache/kafka-native:4.3.2-rc0 > <https://hub.docker.com/layers/apache/kafka-native/4.3.2-rc0/images/sha256-aad4e610fcbbb44b142dfe89c5d1e62262d0323bba68b46092853d3ee961c719> > > * Maven artifacts to be voted upon: > https://repository.apache.org/content/groups/staging/org/apache/kafka/ > > * Javadoc: > https://dist.apache.org/repos/dist/dev/kafka/4.3.2-rc0/javadoc/index.html > > * Tag to be voted upon (off 4.3 branch) is the 4.3.2 tag: > https://github.com/apache/kafka/releases/tag/4.3.2-rc0 > > * Documentation: > https://kafka.apache.org/43/documentation.html > > * Protocol: > https://kafka.apache.org/43/design/protocol > > * Successful CI builds for the 4.3 branch: > Unit/integration tests: > https://github.com/apache/kafka/actions/runs/36498239102 > System tests: [will provide it soon] > > * Successful Docker Image Github Actions Pipeline for 4.3 branch: > Docker Build Test Pipeline (JVM): > https://github.com/apache/kafka/actions/runs/36444796001 > Docker Build Test Pipeline (Native): > https://github.com/apache/kafka/actions/runs/36444991180 > > Thanks, > Jiunn-Yang Huang
