* GCE: Service object now supports "Network Tiers" as an Alpha feature via...

For more information, see [#53040](https://github.com/kubernetes/kubernetes/issues/53040).

* Object quotas are not consistently charged or updated. Specifically, the object count quota does not reliably account for uninitialized objects. Some quotas are charged only when an object is initialized. Others are charged when an object is created, whether it is initialized or not. We plan to fix this issue in a future release.

`objectSelector` 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](htt...

via a new mime-type application/json;as=Table;v=v1alpha1;g=meta.k8s.io. The returned object (if the server supports it) will be of type meta.k8s.io/v1alpha1 with Table, and contain column and row information related to the resource. Each row will contain information about the resource - by default it will be the object metadata, but callers can add the ?includeObject=Object query parameter and receive the full object. In the future kubectl will use this to retrieve the results of `kubectl get`. ([#...

  - A namespaced object with an ownerReference referencing a uid of a namespaced kind which does not exist in the same namespace is now consistently treated as though that owner does not exist, and the child object is deleted.

* kubelets are no longer allowed to delete their own Node API object. Prior to 1.11, in rare circumstances related to cloudprovider node ID changes, kubelets would attempt to delete/recreate their Node object at startup. If a legacy kubelet encounters this situation, a cluster admin can remove the Node object: `kubectl delete node/<nodeName>` ([#62818](https://github.com/kubernetes/kubernetes/pull/62818), [@mikedanese](https://github.com/mikedanese))...

- The `AdmissionReview` API sent to and received from admission webhooks has been promoted to `admission.k8s.io/v1`. Webhooks can specify a preference for receiving `v1` AdmissionReview objects with `admissionReviewVersions: ["v1","v1beta1"]`, and must respond with an API object in the same `apiVersion` they are sent. When webhooks use `admission.k8s.io/v1`,...

- Kube-apiserver: ensures the namespace of objects sent to admission webhooks matches the request namespace. Previously, objects without a namespace set would have the request namespace populated after mutating admission, and objects with a namespace that did not match the request namespace would be rejected after admission. ([#94637](https://github.com/kubernetes/kubernetes/pull/94637),...

- The CSINodeInfo feature gate is deprecated and will be removed in a future release. The storage.k8s.io/v1beta1 CSINode object is deprecated and will be removed in a future release. ([#83474](https://g...

* If the `TokenRequestProjection` feature gate is disabled, projected serviceAccountToken volume sources are now dropped at object creation time, or at object update time if the existing object did not have a projected serviceAccountToken volume source. Previously, these would result in validation errors. ([#72714](https://github.com/kubernetes/kubernetes/pull/72714), [@mourya007](https://github.com/mourya007))...
