Upgrade Kubernetes

The CKS now supports upgrading your Cluster to take advantage of the latest features and security updates in Kubernetes. To upgrade your CKS cluster, follow the steps in Upgrade Kubernetes.

Default Control Group Version Change

Starting with CKS clusters targeting Kubernetes v1.33, the default Node image uses cgroup v2. This change aligns with the upstream Kubernetes support policy and ensures that new clusters are created with the latest recommended configuration.

This change will not affect existing clusters, which will continue to use the previous default Node image until they are upgraded or recreated. See Kubernetes Versions for more information about the Kubernetes versions supported by CKS and the control group versions used.
