alpha support for manifest-based admission control configuration (KEP-5793). When the `ManifestBasedAdmissionControlConfig` feature gate is enabled, admission webhooks and CEL-based policies can be loaded from static manifest files on disk via the `staticManifestsDir` field in `AdmissionConfiguration`. These policies are active from API server startup, survive etcd unavailability, and can protect API-based admission resources from modification. ([#137346](https://github.com/kubernetes/kubernetes/pull/137346),...

- Fixed issue with Winkernel Proxier - IPV6 load balancer policies were missing when service was configured with `ipFamilyPolicy`: `RequireDualStack` ([#115503](https://github.com/kubernetes/kubernetes/pull/115503), [@princepereira](https://github.com/princepereira))

- Introduced `v1alpha1` API for mutating admission policies, enabling extensible #     admission control via CEL expressions (KEP  3962: Mutating Admission Policies). #     To use, enable the `MutatingAdmissionPolicy` feature gate and the `admissionregistration.k8s.io/v1alpha1` #     API via `--runtime-config`.

* Add support for PodSecurityPolicy on GCE: `ENABLE_POD_SECURITY_POLICY=true` enables the admission controller, and installs policies for default addons. ([#52367](https://github.com/kubernetes/kubernetes/pull/52367), [@tallclair](https://github.com/tallclair))

- Added a `--topology-manager-policy-options` flag to the kubelet to support fine tuning the topology manager policies. The first policy option, `prefer-closest-numa-nodes`, allows these policies to favor sets of NUMA nodes with shorter distance between nodes when making admission decisions. ([#112914](https://github.com/kubernetes/kubernetes/pull/112914), [@PiotrProkop](https://github.com/PiotrProkop))...

  - Expanded support for federated hybrid-cloud resources including ReplicaSets, Secrets, Namespaces and Events.
- **Security**
  - Increased pod-level security granularity (eg: Container Image Policies, AppArmor and `sysctl` support)
  - Increased cluster-level security granularity (eg: Access Review API)
