Upgrade Amazon EKS clusters with confidence using Kubernetes version rollbacks
Summary

Amazon EKS now offers Kubernetes version rollbacks, allowing reversal of control plane upgrades (e.g., 1.34 to 1.35) within seven days via a one-minor-version undo. Unlike KEP-4330's emulated versions, EKS restores the previous validated state, with cluster insights flagging compatibility and add-on dependencies. For EKS Auto Mode, rollbacks coordinate node and control plane rollback, respecting pod disruption budgets, with a cancel API to abort node rollbacks.
