Kubernetes is tearing down obsolete test infrastructure while shipping critical control plane upgrades and new conditional authorization capabilities.

The test-infra desk eliminated four redundant CI jobs that became unmaintainable after upstream projects removed dependencies [1] [2] [3] [4] [5]. Azure unmanaged disk tests are gone; GCP kops scenarios retired; kubetest2 build-up-down removed because cloud-provider-gcp no longer ships cluster scripts. This cleanup saves compute resources and stops burning cycles on phantom pipelines. Meanwhile, the EKS Prow build cluster shipped a production upgrade from 1.32 (EOL) to 1.35 with new Terraform modules [6], already applied and stable. On the core kubernetes desk, three high-signal PRs landed: conditional authorization capabilities added to the authz interface [7], RelaxedDNSSearchValidation feature gate removed after three releases at GA [8], and HPA conditions now carry ObservedGeneration metadata [9]. A scheduler fix prevents preemptor pods from getting stuck in unschedulable queues [10], and CPU manager checkpoints generalized to v4 with embedded v2 support for forward compatibility [11]. Release branch management team composition updated for v1.37 [12].

Action items

→ Monitor the EKS Prow cluster upgrade to 1.35 for stability - it's already live [ref:4] kubernetes/k8s.io [monitor]
→ Review conditional authorization changes if you're building custom authz plugins [ref:19] kubernetes/kubernetes [plan]
→ Update any tooling that references RelaxedDNSSearchValidation feature gate [ref:20] kubernetes/kubernetes [plan]
→ Test scheduler behavior with preemptor pods in your environment after the unschedulable queue fix [ref:22] kubernetes/kubernetes [plan]
