- Added CEL runtime cost calculation into ValidatingAdmissionPolicy, matching the evaluation cost
  restrictions that already apply to CustomResourceDefinition.
  If rule evaluation uses more compute than the limit, the API server aborts the evaluation and the
  admission check that was being performed is aborted; the `failurePolicy` for the ValidatingAdmissionPolicy

- Fix the bug where PodIP field is temporarily removed for a terminal pod ([#125404](https://github.com/kubernetes/kubernetes/pull/125404), [@mimowo](https://github.com/mimowo)) [SIG Node and Testing]
- Fixed a bug in ValidatingAdmissionPolicy that caused policies which were using CRD parameters to fail to synchronize ([#123003](https://github.com/kubernetes/kubernetes/pull/123003), [@alexzielenski](https://github.com/alexzielenski)) [SIG API Machinery and Testing]

- `ValidatingAdmissionPolicy` and `ValidatingAdmissionPolicyBinding` objects are
  persisted in `etcd` using the `v1beta1` version. Either remove alpha objects, or disable the
  alpha `ValidatingAdmissionPolicy` feature in a `v1.27` server before upgrading to a

  clearing of the `terminatedEndpoints` map. ([#135146](https://github.com/kubernetes/kubernetes/pull/135146), [@princepereira](https://github.com/princepereira)) [SIG Network and Windows]
- Fixed a bug in `ValidatingAdmissionPolicy` where schemas with `additionalProperties: true` could cause the kube-controller-manager to crash with a nil pointer exception. ([#135155](https://github.com/kubernetes/kubernetes/pull/135155), [@jpbetz](https://github.com/jpbetz))

- Users are now allowed to mutate `FSGroupPolicy` and `PodInfoOnMount` in `CSIDriver.Spec`. ([#116209](https://github.com/kubernetes/kubernetes/pull/116209), [@haoruan](https://github.com/haoruan))
- ValidatingAdmissionPolicy was promoted to GA and will be `enabled` by default. ([#123405](https://github.com/kubernetes/kubernetes/pull/123405), [@cici37](https://github.com/cici37))

- Fixes a spurious "namespace not found" error possible in default configurations in 1.30+ when using ValidatingAdmissionPolicy or MutatingAdmissionPolicy to intercept namespaced objects in newly-created namespaces...

- Fixes bug in ValidatingAdmissionPolicy alpha which prevented policies from using a paramKind previously used by another policy ([#115185](https://github.com/kubernetes/kubernetes/pull/115185), [@alexzielenski](https://github.com/alexzielenski)) [SIG API Machinery]
