Kubernetes v1.36: Mixed Version Proxy Graduates to BetapostThe Kubernetes Mixed Version Proxy moves to Beta in Kubernetes 1.36 and is enabled by default. It routes requests for resources unknown to an older API server to a newer peer instead of returning 404, and it now uses aggregated discovery and merges peer APIs into discovery responses. Clusters need the --peer-ca-file flag set for peer proxying to work, and discovery falls back to local APIs when that flag is absent.platform teamsPlatform teams running multi-control-plane clusters should set --peer-ca-file before upgrading to 1.36, since proxying fails with TLS errors without it. Discovery output will now list APIs from all peers by default, so tooling that expects per-server results can request the profile=nopeer view.Kubernetes Blog ↗written by claude-haiku-5-5, prompt 7cbe154, checked by publish rules
Kubernetes v1.36: New Metric for Route Sync in the Cloud Controller ManagerpostKubernetes v1.36 adds an alpha counter metric, route_controller_route_sync_total, to the Cloud Controller Manager route controller. The metric increments each time routes are synced with the cloud provider. It is intended to help operators A/B test the CloudControllerManagerWatchBasedRoutesReconciliation feature gate, introduced in v1.35, which reconciles routes only when nodes change instead of on a fixed interval.platform teamsPlatform teams can compare sync counts with the feature gate on and off to measure reduced calls to the infrastructure provider API. The source expects a significant drop in sync rate in clusters where nodes change infrequently, but gives no measured figures.Kubernetes Blog ↗editorCorrection 2026-10-20: this was listed as a Amazon EKS v1.36 release by mistake. It is Kubernetes Blog coverage, not release notes from the project.written by claude-haiku-5-5, prompt 7cbe154, checked by publish rules

Kubernetes v1.36: Deprecation and removal of Service ExternalIPsannouncementKubernetes 1.36 formally deprecates the .spec.externalIPs field on Service, which the project says enables security exploits when users are not fully trusted (CVE-2020-8554). Kubernetes now emits warnings when the field is used. The project plans to disable support in kube-proxy at v1.40 at the earliest, with an opt-back-in, and fully at v1.43 at the earliest.platform teamsPlatform teams should check whether any Services set externalIPs and migrate to a LoadBalancer controller such as MetalLB, or to Gateway API, where administrators control IP assignment. Enabling the DenyServiceExternalIPs admission controller is recommended as a precaution against new uses.Kubernetes Blog ↗written by claude-haiku-5-5, prompt 7cbe154, checked by publish rules

Kubernetes v1.36: Advancing Workload-Aware SchedulingpostKubernetes v1.36 introduces the Workload and PodGroup APIs under scheduling.k8s.io/v1alpha2, separating the static Workload template from runtime PodGroup state. It adds a PodGroup scheduling cycle that evaluates a group atomically, along with first iterations of topology-aware scheduling and workload-aware preemption. The release also adds ResourceClaim support for PodGroups and a first phase of Job controller integration with the new API.platform teamsTeams running batch or AI/ML training workloads on Kubernetes will see the v1alpha2 API replace v1alpha1, and the Pod workloadRef field is replaced by schedulingGroup, so manifests and controllers need updating. Gang scheduling and topology placement are alpha, and the source notes limits on heterogeneous groups and inter-Pod dependencies, so plan for partial guarantees.Kubernetes Blog ↗written by claude-haiku-5-5, prompt 7cbe154, checked by publish rules

Kubernetes v1.36: PSI Metrics for Kubernetes Graduates to GApostKubernetes v1.36 graduates Pressure Stall Information (PSI) metrics for the kubelet to general availability, exposing CPU, memory and I/O pressure at node, pod and container level. The Kubernetes SIG Node post reports performance tests on 80-pod density nodes, where the kubelet feature added about 0.1 cores, or 2.5% of node capacity, and the kernel PSI overhead stayed between 0.037 and 0.125 cores. The GA version also stops emitting misleading zero values when the kernel lacks PSI support.platform teamsPlatform teams can scrape PSI metrics from the /metrics/cadvisor endpoint or the Summary API on Linux nodes running kernel 4.20 or later with cgroup v2 and PSI enabled, without enabling a feature gate. Windows nodes will omit these metrics, so mixed clusters need to handle the gap in dashboards and alerts.Kubernetes Blog ↗written by claude-haiku-5-5, prompt 7cbe154, checked by publish rules
