Kubernetes operator for running and managing Apache Kafka clusters

Strimzi 1.3 starts encrypting and authenticating Kafka's internal connections.

kafkakubernetes operatorinternal encryptionrelease candidatesserver-side apply
◆Current state
Strimzi's feed carries release candidates rather than finals. 1.3.0-rc1 on 5 October added early-access configurable encryption and authentication for internal Kafka connections; 1.3.1-rc1 added Kafka 4.3.2 support and fixed concurrency issues left by the Vert.x removal, and 1.3.1-rc2 on 3 November only bumps Jackson. The 1.3 line requires Kubernetes 1.32+, deprecates PKCS12 certificates and drops Kaniko for Buildah.
◆Where it's heading
Since 1.0 removed every CRD API but v1, each minor follows the same pattern: support the newest Kafka, drop the oldest, tighten operator defaults. 1.3 adds security of the cluster's internal traffic to that list.
◆Prediction
A 1.4.0 candidate tracking the next Kafka release is the likely next entry, with the internal-security options possibly leaving early access.

◆Recent moves

    Strimzi 1.3.1 RC2 only bumps Jackson

    The second 1.3.1 candidate changes only a Jackson dependency since rc1, which suggests the patch is close to final. It carries the 1.3 line's Kubernetes 1.32+ floor and PKCS12 deprecation notice.

    1.2.0 RC2 lands one CA logging fix

    The second 1.2.0 candidate carries a single change — incorrect CA logging — against rc1's Kafka 4.3.1 support and per-pod volume templates. The container image table is the bulk of the body. A one-fix candidate three days after the first is the sign of a cycle closing, not of new work arriving.

    Kafka 4.3.1, per-pod volume templates, server-side apply GA

    The 1.2.0 candidate continues the post-1.0 pattern of tracking Apache Kafka releases while tightening operator defaults: Kafka 4.3.1 support, per-pod templated additional volumes, Maven mirror configuration for Connect builds, and broker cordoning during scale-down auto-rebalancing. The ServerSideApplyPhase1 gate reaches GA and is permanently enabled, completing a migration that was staged across earlier releases. Installation files now default to the Restricted Pod Security Standard security context and mount Service Account tokens through a volume instead of auto-mounting them.

    Kafka 4.3.0 support; 4.1.x dropped; connector stop semantics fixed

    The 1.1.0 candidate set the cadence the 1.2.0 line follows: add the newest Kafka versions, drop the oldest, and fix connector state semantics. Its tlsroute Gateway API listener and per-broker template options are the same kind of configuration-surface widening that 1.2.0 extends with per-pod volumes.
