  `volume_manager_total_volumes`
  ([#84907](https://github.com/kubernetes/kubernetes/pull/84907), [@RainbowMango](https://github.com/RainbowMango))
- Deprecated metric `rest_client_request_latency_seconds` has been turned off. ([#83836](https://github.com/kubernetes/kubernetes/pull/83836), [@RainbowMango](https://github.com/RainbowMango))
- Following metrics from kubelet are now marked as with the ALPHA stability level:

- `DRAResourceClaimDeviceStatus` is now turned on by default allowing DRA-Drivers to report device status data for each allocated device. ([#130814](https://github.com/kubernetes/kubernetes/pull/130814), [@LionelJouin](https://github.com/LionelJouin)) [SIG Network and Node]

  * 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`.
  * More details on these feature here:
    https://kubernetes.io/docs/tasks/administer-cluster/reserve-compute-resources/

    * + 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:

  - 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))

- 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))

- Controller manager serve workqueue metrics ([#87967](https://github.com/kubernetes/kubernetes/pull/87967), [@zhan849](https://github.com/zhan849)) [SIG API Machinery]
- Following metrics have been turned off:
  - kubelet_pod_worker_latency_microseconds
  - kubelet_pod_start_latency_microseconds
  - kubelet_cgroup_manager_latency_microseconds
  - kubelet_pod_worker_start_latency_microseconds

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.

## Urgent Upgrade Notes 

- Fixed resource deletion failure caused by quota calculation error when `InPlacePodVerticalScaling` is turned on. ([#122701](https://github.com/kubernetes/kubernetes/pull/122701), [@carlory](https://github.com/carlory))
