- API priority and fairness graduated to beta. 1.19 servers with APF turned on should not be run in a multi-server cluster with 1.20+ servers. ([#96527](https://github.com/kubernetes/kubernetes/pull/96527), [@adtac](https://github.com/adtac)) [SIG API Machinery and Testing]

    * + to use:
    * A new service spec field `Service.Spec.IPFamily` has been added. The default of this field is family of (first service cidr in --service-cluster-ip-range flag). The value is defaulted as described above  once the feature gate is turned on. Here are the possible values for this field:

        },
        "spanish_keywords": {
          "type":       "keyword_marker",
          "keywords": ["¡Hola", "mundo", "búsqueda"]
        },
        "spanish_stemmer": {

        },
        "spanish_keywords": {
          "type":       "keyword_marker",
          "keywords": ["¡Hola", "mundo", "búsqueda"]
        },
        "spanish_stemmer": {

  * Hard Eviction Thresholds will be subtracted from Capacity while calculating
    Node Allocatable. This will result in a reduction of schedulable capacity in
    clusters post upgrade where kubelet hard eviction has been turned on for
    memory. To opt-out set `--experimental-allocatable-ignore-eviction=true`.

- Promoted the feature gate `ValidtaingAdmissionPolicy` to beta, and it is turned off by default. ([#119409](https://github.com/kubernetes/kubernetes/pull/119409), [@alexzielenski](https://github.com/alexzielenski))

  - A custom resource is considered to participate the spec/status convention if and only if the "CustomResourceSubresources" feature gate is turned on and the CRD has `.spec.subresources.status={}`.
- Fixed patch/update operations on multi-version custom resources ([#70087](https://github.com/kubernetes/kubernetes/pull/70087), [@liggitt](https://github.com/liggitt))

After migration, Kubernetes users may continue to rely on all the functionality of in-tree storage plugins using the existing interface.
- CSI Migration feature is turned on by default but stays in Beta for GCE PD, AWS EBS, and Azure Disk in 1.23.
- CSI Migration is introduced as an Alpha feature for Ceph RBD and Portworx in 1.23.
