	The v1beta1 API used an annotation on Namespaces to activate the DefaultDeny policy for an entire Namespace. To activate default deny in the v1 API, you can create a NetworkPolicy that matches all Pods but does not allow any traffic:

    ```yaml
    kind: NetworkPolicy
    apiVersion: networking.k8s.io/v1
    metadata:
      name: default-deny
    spec:
      podSelector:
    ```

- 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. ([#94...

	response, err = s.client.Do(request)
	c.Assert(err, nil)
	c.Assert(response.StatusCode, http.StatusOK)

	bucketPolicyReadBuf, err := io.ReadAll(response.Body)
	c.Assert(err, nil)
	// Verify if downloaded policy matches with previously uploaded.
	expectedPolicy, err := policy.ParseBucketPolicyConfig(strings.NewReader(bucketPolicyStr), bucketName)
	c.Assert(err, nil)

  * Mediates issue [#36859](https://github.com/kubernetes/kubernetes/pull/36859). StatefulSet only acts on Pods whose identity matches the StatefulSet, providing a partial mediation for overlapping controllers.

### Taints and Tolerations

- Azurefile: Normalize share name to not include capital letters ([#100731](https://github.com/kubernetes/kubernetes/pull/100731), [@kassarl](https://github.com/kassarl)) [SIG Cloud Provider and Storage]
- EndpointSlice IP validation now matches Endpoints IP validation. ([#101084](https://github.com/kubernetes/kubernetes/pull/101084), [@robscott](https://github.com/robscott)) [SIG Apps and Network]

- Added `objectSelector` to admission webhook configurations. `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...

  The scheduling hints allow the scheduler to only retry scheduling a `Pod`
  that was previously rejected by the `NodeAffinity` plugin if a new `Node` or a `Node` update matches the `Pod`'s node affinity. ([#119155](https://github.com/kubernetes/kubernetes/pull/119155), [@carlory](https://github.com/carlory))
- `kubeadm`: promoted feature gate `EtcdLearnerMode` to `beta`. Learner mode for

- The alpha `Initializers` admission plugin is no longer enabled by default. This matches the off-by-default behavior of the alpha API which drives initializer behavior. ([#66039](https://github.com/kubernetes/kubernetes/pull/66039), [@liggitt](https://github.com/liggitt))
