Strimzi vs Helm: at a glance
What is Strimzi?
Strimzi hit 1.0 by deleting every CRD API except v1 — conversion is mandatory before upgrade.
The operator reached 1.0.0 by removing the v1beta2, v1beta1 and v1alpha1 CRD APIs entirely and moving fully to v1, with every release since carrying the same blocking warning: convert all custom resources and upgrade the CRDs before upgrading. The 0.45.x branch was closed out with a final patch. Since 1.0, work has been Kafka version tracking — 4.3.0 and 4.2.1 added, 4.1.x dropped — plus connector lifecycle corrections.
What is Helm?
Helm runs two trains while v3 walks toward end-of-life
Helm maintains parallel v3.21.x and v4.2.x lines, releasing patches on both within minutes of each other. The v3 releases now carry an explicit end-of-life warning directing users to v4. Release notes are mostly boilerplate community links, with a short Notable Changes list when anything is worth naming.

◆ Current state
The operator reached 1.0.0 by removing the v1beta2, v1beta1 and v1alpha1 CRD APIs entirely and moving fully to v1, with every release since carrying the same blocking warning: convert all custom resources and upgrade the CRDs before upgrading. The 0.45.x branch was closed out with a final patch. Since 1.0, work has been Kafka version tracking — 4.3.0 and 4.2.1 added, 4.1.x dropped — plus connector lifecycle corrections.
◆ Where it's heading
This is a project that spent its 0.x years accumulating API versions and used the 1.0 boundary to shed all of them at once. The consequence is a hard migration gate for every existing installation, which is why the warning leads every release page rather than sitting in an upgrade appendix. Post-1.0 releases look like ordinary operator maintenance: track new Kafka versions, drop old ones, fix reconciliation ordering.
◆ Prediction
Expect the 1.1 line to reach stable and settle into a rhythm of adding each new Apache Kafka release and dropping the oldest, with the CRD conversion warning persisting until most of the installed base has moved.
Helm
5.0INFRA · APIS
Helm runs two trains while v3 walks toward end-of-life
◆ Current state
Helm maintains parallel v3.21.x and v4.2.x lines, releasing patches on both within minutes of each other. The v3 releases now carry an explicit end-of-life warning directing users to v4. Release notes are mostly boilerplate community links, with a short Notable Changes list when anything is worth naming.
◆ Where it's heading
Both trains are in maintenance rather than feature mode. The recurring work is keeping the Kubernetes client libraries current — v1.36 in this window — and fixing concurrency defects in the v4 waiter and kube-client code that surface when install, upgrade, rollback and uninstall run against the same client. Where v4 does add anything, it is small and toolchain-shaped: goreleaser builds, a mustToToml template function, flag deprecations.
◆ Prediction
The dual-patch pattern will continue in lockstep until v3 reaches its announced end-of-life, after which only the v4 line should keep receiving releases. Nothing in these entries indicates a date for that cutover.
