### Serverside Apply - Beta 2

- Kube-apiserver now reports latency metric for JWT authenticator authenticate token decisions in the `apiserver_authentication_jwt_authenticator_latency_seconds` metric, labeled by jwtIssuer hash and result. ([#123225](https://github.com/kubernetes/kubernetes/pull/123225), [@aramase](https://github.com/aramase))

*   [alpha] Topology Aware Volume Scheduling
    *   Improved volume scheduling for Local PersistentVolumes, by allowing the scheduler to make PersistentVolume binding decisions while respecting the Pod's scheduling requirements.
    *   Dynamic provisioning is not supported with this feature yet.
*   [alpha] Containerized mount utilities

- Kube-apiserver: Added support for disabling caching of authorization webhook decisions in the `--authorization-config` file. The new fields `cacheAuthorizedRequests` and `cacheUnauthorizedRequests` could be set to `false` to prevent caching for authorized or unauthorized requests. See the https://kubernetes.io/docs/reference/acces...

- Fixed a regression in the pod binding subresource to honor the `metadata.uid` precondition.
  This allows kube-scheduler to ensure it is assigns node names to the same instances of pods it made scheduling decisions for. ([#116550](https://github.com/kubernetes/kubernetes/pull/116550), [@alculquicondor](https://github.com/alculquicondor))

- Fixed the reporting of elapsed times during evaluation of `ValidatingAdmissionPolicy` decisions and annotations. The apiserver_validating_admission_policy_check_duration metrics will now show elapsed times and no longer be zero. ([#128463](https://github.com/kubernetes/kubernetes/pull/128463), [@knrc](https://github.com/knrc))

- Fixes a regression in the pod binding subresource to honor the `metadata.uid` precondition.
  This allows kube-scheduler to ensure it is assigns node names to the same instances of pods it made scheduling decisions for. ([#116763](https://github.com/kubernetes/kubernetes/pull/116763), [@alculquicondor](https://github.com/alculquicondor)) [SIG API Machinery and Testing]

- This PR added tracing support to the kubelet's read-only endpoint, which currently
  does not have tracing. It makes use of the `WithPublicEndpoint` option to prevent callers
  from influencing sampling decisions. ([#121770](https://github.com/kubernetes/kubernetes/pull/121770), [@frzifus](https://github.com/frzifus)) [SIG Node]

* PodDisruptionBudget now uses [ControllerRef](https://github.com/kubernetes/community/blob/master/contributors/design-proposals/api-machinery/controller-ref.md) to make the right decisions about Pod eviction even if the built in application controllers have overlapping selectors.

### **Security**
#### Admission Control

### Additional Notable Feature Updates

- [Topology Manager](https://github.com/kubernetes/enhancements/issues/693), a new Kubelet component, aims to co-ordinate resource assignment decisions to provide optimized resource allocations.
- [IPv4/IPv6 dual-stack](https://kubernetes.io/docs/concepts/services-networking/dual-stack) enables the allocation of both IPv4 and IPv6 addresses to Pods and Services.
