Stable highlights (learner-visible)

Section titled “Stable highlights (learner-visible)”
ThemeWhat shippedWhy it matters
Workload identityPod certificates + ClusterTrustBundles StableNative X.509 + trust anchors without bolting on a full mesh just for certs
AutoscalingConfigurable HPA tolerance StablePer-resource tolerance instead of one global knob
UX / APIKYAML Stable; metrics.k8s.io API definitions StableSafer kubectl YAML subset; metrics API leaves permanent-beta territory
DRADevice taints/tolerations, extended resources via DRA, resource health, NUMA attrs, NIC statusHardware scheduling closer to node-taint mental models
OpsNode declared features, resilient watch-cache init, Storage Version Migrator in-treeSafer skew and storage-version migrations

Beta worth watching (not deep-taught here): Pod-level resource managers (PodLevelResourceManagers, disabled by default); HPA scale-to-zero; manifest-based admission config on disk.

Practice

Section titled “Practice”
  • kind image: kindest/node:v1.37.0 — matrix
  • Try KYAML output on a known Deployment; compare with classic YAML.
  • Optional: only with an explicit feature-gated kind config — do not treat pod-level resource managers as GA.

Agent checklist

Section titled “Agent checklist”
  • Keep latest_stable_track.supported_minors including 1.37
  • Do not bump exam_pin
  • Prefer official blog + CHANGELOG over third-party roundups when they disagree
