Before upgrading, we strongly recommend verifying your current setup against the information on this page and reading more about Kubernetes' new features in Kubernetes urgent upgrade notes.
Deprecated API Services
With this version, Kubernetes stopped serving several API versions for CronJob, EndpointSlice, Event, HorizontalPodAutoscaler, PodDisruptionBudget, PodSecurityPolicy, and RuntimeClass services. For more information on the deprecated API versions for each of these services, refer to https://kubernetes.io/docs/reference/using-api/deprecation-guide/#v1-25.
New OCI Image Registry
DKP now uses the upstream
registry.k8s.io registry instead of the previous
k8s.gcr.io registry for all new and upgraded clusters.
Ensure you add
registry.k8s.io to any firewall or proxy allowlists.
