  * 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))

* Change merge key for VolumeMount to mountPath ([#35071](https://github.com/kubernetes/kubernetes/pull/35071), [@thockin](https://github.com/thockin))
* Turned-off etcd listening on public ports as potentially insecure. Removed ([#35192](https://github.com/kubernetes/kubernetes/pull/35192), [@jszczepkowski](https://github.com/jszczepkowski))
    * experimental support for master replication.

* Cadvisor root path configuration ([#35136](https://github.com/kubernetes/kubernetes/pull/35136), [@dashpole](https://github.com/dashpole))
* ssh pubkey parsing: prevent segfault ([#35323](https://github.com/kubernetes/kubernetes/pull/35323), [@mikkeloscar](https://github.com/mikkeloscar))



# v1.5.0-alpha.2

- 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.
