Hi Jiunn-Yang, Thanks for running the release.
I did the following to validate RC3: - Verified the signatures and checksums of the source, binary, site-docs and release notes artifacts, and of all the staged Maven artifacts - Checked that the source tarball matches the 4.3.2-rc3 tag - Built from source and ran the unit tests with JDK 17 and JDK 25 - Ran the quickstart with the binary on JDK 17 and JDK 25, with classic and consumer groups - Did a rolling upgrade of a 3-node combined cluster from 4.3.1 to 4.3.2 while producing and consuming (classic and consumer groups) - Ran the apache/kafka and apache/kafka-native images - Built a small producer/consumer/admin app against the staged Maven artifacts and ran it with JDK 17 and JDK 25 - Spot checked the release notes, Javadoc and documentation +1 (binding) Best, David On Mon, Oct 12, 2026 at 11:15 PM Bill Bejeck <[email protected]> wrote: > > Hi Jiunn-Yang, > > Thanks for running the 4.3.2 release. > > I did the following to validate RC3: > > - Verified checksums (md5/sha1/sha512) and GPG signatures > - Artifacts: source, binary, site-docs, RELEASE_NOTES > - Signed by Jiunn Yang Huang <[email protected]> > - Key 062C22C0F467AF9A02D512B5504473FAF80CBBCB > - Verified GPG signatures of the Maven staging artifacts > - 65 modules, all signed with the same key as the tarballs > - Built from source with JDK 17 > - Ran the core, clients and streams unit tests > - Ran quickstarts from the bundled site-docs against the binary dist > - 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-rc3 > - apache/kafka-native:4.3.2-rc3 > - Checked shipped jar versions for the dependency and CVE bumps > - jackson-core and jackson-databind 2.21.7 > - log4j 2.25.5 > - jetty 12.0.37 > - lz4-java 1.11.4 > - snappy-java 1.1.10.11 > - Exercised the rc3 dependency bumps against a local broker > - lz4/snappy/zstd/gzip round trips, incl. broker recompression > - Connect REST and partition reassignment JSON (Jackson) > - Exercised these fixes by hand, comparing against 4.3.1 > - Clients: > - KAFKA-20700, KAFKA-20769 > - Streams: > - KAFKA-20464 > - Group coordinator: > - KAFKA-20434 > > - Docs still reference 4.3.1 quickstart etc - not a blocker we can do a > follow-up PR. > > +1 (binding) > > Thanks, > Bill > > On Mon, Oct 12, 2026 at 6:20 AM Mickael Maison <[email protected]> > wrote: > > > Hi, > > > > I did the following testing: > > - checked signatures and checksums > > - built from source > > - ran quickstart with Java 20 and both docker images > > > > Just one nit: the javadoc were generated with <html lang="zh">, so > > most browsers bring up the translation dialog when you open them > > > > + (binding) > > > > Thanks, > > Mickael > > > > On Mon, Oct 12, 2026 at 11:35 AM Jakub Scholz <[email protected]> wrote: > > > > > > +1 (non-binding).
