• Jan 14, 2026 CAPA releases releases aws-33.1.2

  Improve karpenter subnet selection and extraConfig mounting.

  Changes compared to v33.1.1

  Components

  • cluster-aws from v6.4.1 to v6.4.2

  cluster-aws v6.4.1…v6.4.2

  Added

  • Add kubernetes.io/cluster/$clusterName: "owned" and sigs.k8s.io/cluster-api-provider-aws/cluster/$clusterName: "owned" tags to the IRSAClaim CR so that resources created by Crossplane contain the expected tags. This also allows to find the S3 buckets that need to be deleted when removing a cluster.

  Fixed

  • Fix Karpenter NodePool subnet filtering: when users define custom subnetTags, the default giantswarm.io/role: "nodes" filter is no longer applied, allowing full control over subnet selection. The cluster ownership tag (sigs.k8s.io/cluster-api-provider-aws/cluster/<cluster-name>: owned) is still enforced for security.
  • Fix Karpenter HelmRelease: add missing valuesFrom parent field for extraConfigs, enabling customers to use custom ConfigMaps and Secrets for Karpenter configuration.
