### API Change

- 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]

* Added the ability to select pods in a chosen node to be drained based on given pod label-selector. ([#56864](https://github.com/kubernetes/kubernetes/pull/56864), [@juanvallejo](https://github.com/juanvallejo))

* add field selector for kubectl get ([#50140](https://github.com/kubernetes/kubernetes/pull/50140), [@dixudx](https://github.com/dixudx))

* Deployment will stop adding pod-template-hash labels/selector to ReplicaSets and Pods it adopts. Resources created by Deployments are not affected (will still have pod-template-hash labels/selector).  ([#61615](https://github.com/kubernetes/kubernetes/pull/61615), [@janetkuo](https://github.com/janetkuo))

 - 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

- 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]

is evaluated the oldObject and newObject that would be sent to the webhook, and is considered to match if either object matches the selector. A null object (oldObject in the case of create, or newObject in the case of delete) or an object that cannot have labels (like a DeploymentRollback or a PodProxyOptions object) is not considered to match. Use the object selector only if the webhook is opt-in, because end users may skip the admission webhook by setting the labels. ([#78505](https://github.co...
