v3.21.2Kubernetes CoreJun 20, 2026
Helm v3.21.2 updates Kubernetes client libraries to match v1.36. This is a routine patch for client library alignment; upgrade to stay compatible with Kubernetes v1.36 clusters.
enhancementUpdate to v1.21.2 if you run Kubernetes v1.36
Helm v3.21.2 updates its Kubernetes client libraries (client-go) to match the v1.36 API. If you already run Kubernetes v1.36 clusters, upgrade Helm to v3.21.2 to ensure full compatibility and avoid potential client-server version skew issues. Teams on earlier Kubernetes versions are not blocked — the upgrade is optional but recommended for consistency.
