  • Resolved an issue where the Kubernetes Lease resource created using Helm was missing standard Kubernetes labels:

Vulnerability Fixes

1.20.0 February 26, 2026

Supported shield chart version: 1.30.0

Enhancements

  • Lease resources are no longer managed by the Helm chart and are now created directly by Cluster Shield with an ownerReference configured. Their lifecycle is delegated to Kubernetes garbage collection, ensuring automatic cleanup when the owning component is removed. This improves upgrade reliability, prevents orphaned resources, reduces operational complexity, and aligns resource management with native Kubernetes behavior for more predictable deployments.
