Hi Andrew, Thanks for running the release.
* Built from source with openjdk 17 and 21 * Verified basic produce/consume * Validated the checksums and keys * Ran basic quickstart using apache/kafka:4.1.2-rc1 and apache/kafka-native:4.1.2-rc1 docker image The protocol link is changed to https://kafka.apache.org/41/design/protocol/. I created a PR to fix it. https://github.com/apache/kafka/pull/21628 Thank you, PoAn > On Mar 2, 2026, at 6:39 PM, Viktor Somogyi-Vass <[email protected]> > wrote: > > Hi Andrew, > > * verified the gpg signatures > * looked at the release notes > * checked that the artifacts can be resolved in maven > * ran the quickstart and clients against them > * ran the docker quickstart > * checked the docs > > Apart from the protocol link pointing to the old docs (I think) all seems > good. > > +1 (binding) > > Thanks for running the release! > > Viktor > > On Wed, Feb 25, 2026 at 2:13 PM Andrew Schofield <[email protected]> > wrote: > >> Hello Kafka users, developers and client-developers, >> >> This is the first candidate for release of Apache Kafka 4.1.2. >> >> This is the second bug fix release for Apache Kafka 4.1 with fixes as >> described in the release notes. >> >> Release notes for the 4.1.2 release: >> https://dist.apache.org/repos/dist/dev/kafka/4.1.2-rc1/RELEASE_NOTES.html >> >> *** Please download, test and vote by Wednesday, March 4 2026, 9am UTC. >> >> Kafka's KEYS file containing PGP keys we use to sign the release: >> https://dist.apache.org/repos/dist/release/kafka/KEYS >> >> * Release artifacts to be voted upon (source and binary): >> https://dist.apache.org/repos/dist/dev/kafka/4.1.2-rc1/ >> >> * Docker release artifacts to be voted upon: >> apache/kafka:4.1.2-rc1 >> apache/kafka-native:4.1.2-rc1 >> >> * 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/4.1.2-rc1/javadoc/ >> >> * Tag to be voted upon (off 4.1 branch) is the 4.1.2 tag: >> https://github.com/apache/kafka/releases/tag/4.1.2-rc1 >> >> * Documentation: >> https://kafka.apache.org/41/documentation.html >> >> * Protocol: >> https://kafka.apache.org/41/protocol.html >> >> * Successful CI builds for the 4.1 branch: >> Unit/integration tests: >> https://github.com/apache/kafka/actions/runs/22355871722 >> >> System tests: >> https://confluent-open-source-kafka-branch-builder-system-test-results.s3-us-west-2.amazonaws.com/trunk/2026-02-24--002.59fb52a4-4668-45ab-9ffa-bd60aad81cd4--1771979898--confluentinc--4.1--631c2c8761/report.html >> One failure which has been present across several releases: >> - >> tests/kafkatest/tests/tools/replica_verification_test.py::ReplicaVerificationToolTest.test_replica_lags@ >> {"metadata_quorum":"ISOLATED_KRAFT"} >> >> * Successful Docker Image Github Actions Pipeline for 4.1 branch: >> Docker Build Test Pipeline (JVM): >> https://github.com/apache/kafka/actions/runs/22391397131 >> Docker Build Test Pipeline (Native): >> https://github.com/apache/kafka/actions/runs/22392649516 >> >> Thanks, >> Andrew Schofield >>
