* requests from a node for a TLS client certificate for itself are approved if the CSR creator has `create` permission on the `certificatesigningrequests` resource and the `selfnodeclient` subresource in the `certificates.k8s.io` API group

  - `Approved` and `Denied` conditions are mutually exclusive
  - `Approved`, `Denied`, and `Failed` conditions can no longer be removed from a CSR ([#90191](https://github.com/kubernetes/kubernetes/pull/90191), [@liggitt](https://github.com/liggitt)) [SIG API Machinery, Apps, Auth, CLI and Node]

        * requests from a node for a TLS client certificate for itself are approved if the CSR creator has `create` permission on the `certificatesigningrequests` resource and the `selfnodeclient` subresource in the `certificates.k8s.io` API group

- The `conditionType` is "oneof" approved/denied check of CertificateSigningRequest's `.status.conditions` field was migrated to declarative validation. 
  If the `DeclarativeValidation` feature gate was enabled, mismatches with existing validation are reported via metrics.

* `apiservices/status` and `certificatesigningrequests/status` now support `GET` and `PATCH` ([#64063](https://github.com/kubernetes/kubernetes/pull/64063), [@roycaihw](https://github.com/roycaihw))

- Dropped support for `certificates/v1beta1` `CertificateSigningRequest` in `kubectl`. ([#134782](https://github.com/kubernetes/kubernetes/pull/134782), [@scaliby](https://github.com/scaliby))

can be interacted with via general availability APIs. This removal includes beta versions of `ValidatingWebhookConfiguration`, `MutatingWebhookConfiguration`, `CustomResourceDefinition`, `APIService`, `TokenReview`, `SubjectAccessReview`, `CertificateSigningRequest`, `Lease`, `Ingress`, and `IngressClass` APIs.

* Fixes an HPA-related panic due to division-by-zero. ([#39694](https://github.com/kubernetes/kubernetes/pull/39694), [@DirectXMan12](https://github.com/DirectXMan12))

### Certificates

- consumers of the 'certificatesigningrequests/approval' API must now have permission to 'approve' CSRs for the specific signer requested by the CSR. More information on the new signerName field and the required authorization can be found at https://kubernetes.io/docs/reference/acce...

- The CertificateSigningRequest `spec.expirationSeconds` API field has graduated to GA. The `CSRDuration` feature gate for the field is now unconditionally enabled and will be removed in 1.26. ([#108782](https://github.com/kubernetes/kubernetes/pull/108782), [@cfryanr]...
