Kubernetes is purging three deprecated API versions ahead of 1.37 release while kOps moves fast to align with Karpenter v1 semantics and drops support for obsolete master node labels.

The core Kubernetes repository merged cleanup work removing v1alpha1 clustertrustbundles, v1beta1 IPAddress/ServiceCIDR, and v1beta1 volumeattributesclasses [1], all deprecated in 1.34 and replaced by newer versions. This is the expected cadence: APIs get three releases before removal. In parallel, kOps is executing a coordinated upgrade to Karpenter v1.13.0 [2] with three foundational changes happening simultaneously. First, kOps now matches Karpenter's v1 label scheme by replacing the deprecated karpenter.sh/provisioner-name with karpenter.sh/nodepool [3]. Second, it's removing affinity rules keyed on the obsolete node-role.kubernetes.io/master label [4], which hasn't existed since Kubernetes 1.24/1.25. Third, kOps is adopting kustomize-based generation for the Karpenter addon manifest [5], eliminating hand-applied customizations that broke on every version bump. On the test-infra side, DRA (Dynamic Resource Allocation) is getting comprehensive E2E node presubmit coverage [6] to catch regressions before they land in kubernetes/kubernetes. The cacher subsystem refactored its key handling [7] to support sharing utilities across components, and the workload API gained mutability for minCount fields [8], improving flexibility for batch scheduling scenarios.
