- PersistentVolumeLabel admission plugin, responsible for labeling `PersistentVolumes` with topology labels, now does not overwrite existing labels on PVs that were dynamically provisioned. It trusts the  dynamic provisioning that it provided the correct labels to the `PersistentVolume`, saving one potentially expensive cloud API call. `PersistentVolumes` created manually by users are labelled by the admission plugin in the same...

- The `volume_zone` plugin will consider `beta` labels as `GA` labels during the scheduling
  process. Therefore, if the values of the labels are the same, PVs with `beta` labels
  can also be scheduled to nodes with `GA` labels. ([#118923](https://github.com/kubernetes/kubernetes/pull/118923), [@AxeZhan](https://github.com/AxeZhan))

  For metrics `etcd_request_duration_seconds`, `etcd_requests_total` and `etcd_request_errors_total` replace `type` label with API `resource` and `group` label.
  For metric `apiserver_selfrequest_total` add a API `group` label.
  For metrics `apiserver_watch_events_sizes` and `apiserver_watch_events_total` replace API `kind` label with `resource` label.

 - Newly provisioned PVs by gce-pd will no longer have the beta FailureDomain label. gce-pd volume plugin will start to have GA topology label instead. ([#98700](https://github.com/kubernetes/kubernetes/pull/98700),...

* This change applies zone labels to vSphere Volumes automatically. The zone labels are visible on the PV: ([#72687](https://github.com/kubernetes/ku...

- Pods owned by a Job now uses the labels `batch.kubernetes.io/job-name` and `batch.kubernetes.io/controller-uid`.
  The legacy labels `job-name` and `controller-uid` are still added for compatibility. ([#114930](https://github.com/kubernetes/kubernetes/pull/114930), [@kannon92](https://github.com/kannon92))

  - cAdvisor json endpoints have been deprecated since 1.15. ([#78504](https://github.com/kubernetes/kubernetes/pull/78504), [@dashpole](https://github.com/dashpole))

- e2e framework: `framework.WithFeatureGate` `[Alpha]`, `[Beta]` and `[Feature:OffByDefault]` tags are now set 1:1 with `Alpha`,  `Beta`, `Feature:OffByDefault` Ginkgo labels, replacing`Feature:Alpha` and `Feature:Beta` labels. `BetaOffByDefault` is also added as a Ginkgo label only for off-by-default beta features ([#130908](https://github.com/kubernetes/kubernetes/pull/130908), [@BenTheElder](https://github.com/BenTheElder)) [SIG Testing]

  - Make "kubeadm upgrade apply" add the "node-role.kubernetes.io/control-plane" label on existing nodes that only have the "node-role.kubernetes.io/master" label during upgrade.
  - Please adapt your tooling built on top of kubeadm to use the "node-role.kubernetes.io/control-plane" label.

- When specifying an invalid value for a label, it was not always clear which label the value was specified for. Starting with this release, the label's key is included in such error messages, which makes debugging easier.
