Hi Jiunn-Yang, Thanks for running the 4.3.2 release.
I did the following to validate 4.3.2-rc0: - Verified checksums (md5/sha1/sha512) and GPG signatures - Artifacts: source, binary, site-docs, RELEASE_NOTES - Signed by Jiunn Yang Huang <[email protected]> - Key 062C22C0F467AF9A02D512B5504473FAF80CBBCB - Built from source with JDK 17 - Ran the core, clients and streams unit tests - Ran quickstarts from the bundled site-docs against the binary distribution - Broker quickstart - Kafka Streams WordCount quickstart - Used both the classic and streams (KIP-1071) group protocols - Ran the same quickstarts against the Docker images - apache/kafka:4.3.2-rc0 - apache/kafka-native:4.3.2-rc0 - Checked shipped jar versions for the dependency and CVE bumps - jackson-databind 2.21.6 - log4j 2.25.5 - jetty 12.0.37 - lz4-java 1.11.2 - jline 3.30.15 (jline-remote-telnet no longer shipped) - Exercised these bug fixes by hand against local clusters - Streams: - KAFKA-14597, KAFKA-20464, KAFKA-20711, KAFKA-20782 - KAFKA-20876, KAFKA-20877, KAFKA-20940 - Broker: - KAFKA-20354 (docs), KAFKA-20434, KAFKA-20442, KAFKA-20533 - KAFKA-20601, KAFKA-20832, KAFKA-21096 - Clients: - KAFKA-20700, KAFKA-20769, KAFKA-20780 - Connect: - KAFKA-20450, KAFKA-20555 I noticed a few minor non-blocking issues: - The apache/kafka link in the vote email carries sha256:aad4e610..., which is the linux/amd64 manifest of apache/kafka-native. The apache/kafka:4.3.2-rc0 index is sha256:5bd263149a366634adda4a2963aa8d80e7430b8eaa09bb685058df883f957b48 - These JIRAs have commits in 4.3.2-rc0 but no fix version, so they are missing from RELEASE_NOTES.html: - KAFKA-13499 (windowed restore now skips expired records) - KAFKA-20870, KAFKA-20875, KAFKA-20916 - The quickstarts still reference 4.3.0 downloads and tags +1 (binding) Thanks, Bill On Tue, Sep 29, 2026 at 8:24 AM 黃竣陽 <[email protected]> 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
