### API Change

  don't match the node affinity/selector. This may lead to unschedulable pods if you previously had pods
  matching the spreading selector on those excluded nodes (not matching the node affinity/selector),
  especially when the `topologyKey` is not node-level. Revisit the node affinity and/or pod selector in the

  * You can remove the "old" taints (stored internally as annotations) at any time...

### API Change

- Kube-apiserver: fixed a bug returning inconsistent results from list requests which set a field or label selector and set a paging limit ([#94002](https://github.com/kubernetes/kubernetes/pull/94002), [@wojtek-t](https://github.com/wojtek-t)) [SIG API Machinery]

 - For all kinds in the API group version, a spec.selector default value is no longer
 available, because it's incompatible with `kubectl
 apply` and strategic merge patch. You must explicitly set the spec.selector value
 in your manifest. An object with a spec.selector value that does not match the labels in
 its spec.template is invalid.

 - Selector mutation is disabled for all kinds in the

### API Change

  - kube-proxy addon starts to use the label `node.kubernetes.io/kube-proxy-ds-ready` instead of `beta.kubernetes.io/kube-proxy-ds-ready` as its node selector.
  - metadata-proxy addon starts to use the label `cloud.google.com/metadata-proxy-ready` instead of `beta.kubernetes.io/metadata-proxy-ready` as its node selector.

#### Storage

- Fixed an issue to not drain all the pods in a namespace when an empty-selector i.e. "{}" is specified in a Pod Disruption Budget (PDB) ([#121132](https://github.com/kubernetes/kubernetes/pull/121132), [@sairameshv](https://github.com/sairameshv)) [SIG Apps]

- JWT authenticators specified via the `AuthenticationConfiguration.jwt` array can now optionally specify either the `controlplane` or `cluster` egress selector by setting the `issuer.egressSelectorType` field.  When unset, the prior behavior of using no egress selector is retained.  The StructuredAuthenticationConfigurationEgressSelector beta feature (default on) must be enabled to use this functionality.
