### **Cluster Federation**
#### Placement Policy
* [alpha] The federation-apiserver now supports a SchedulingPolicy admission controller that enables policy-based control over placement of federated resources. For more information, see [Set up placement policies in Federation](https://kubernetes.io/docs/tasks/federation/set-up-placement-policies-federation/).

#### Cluster Selection

### StatefulSet

* Fix zone placement heuristics so that multiple mounts in a StatefulSet pod are created in the same zone ([#40910](https://github.com/kubernetes/kubernetes/pull/40910), [@justinsb](https://github.com/justinsb))

### CLI

- Fixed `kubectl exec` usage string to correctly reflect flag placement. ([#77589](https://github.com/kubernetes/kubernetes/pull/77589), [@soltysh](https://github.com/soltysh))

* Add Japanese translation for kubectl ([#46756](https://github.com/kubernetes/kubernetes/pull/46756), [@girikuncoro](https://github.com/girikuncoro))
* federation: Add admission controller for policy-based placement ([#44786](https://github.com/kubernetes/kubernetes/pull/44786), [@tsandall](https://github.com/tsandall))

- Simple script based hyperkube image that bundles all the necessary binaries. This is an equivalent replacement for the image based on the go based hyperkube command + image. ([#84662](https://github.com/kubernetes/kubernetes/pull/84662), [@dims](https://github.com/dims))

- The following deprecated metrics are removed, please convert to the corresponding metrics:
  - The following replacement metrics are available from v1.14.0:
      - `rest_client_request_latency_seconds` -> `rest_client_request_duration_seconds`
      - `scheduler_scheduling_latency_seconds` -> `scheduler_scheduling_duration_seconds `

- Fixed the replacement tag in APIs so it no longer acted as a selector for storage version. ([#135197](https://github.com/kubernetes/kubernetes/pull/135197), [@Jefftree](https://github.com/Jefftree))

- Kubeadm: remove the deprecated command `kubeadm config view`. A replacement for this command is `kubectl get cm -n kube-system kubeadm-config -o=jsonpath="{.data.ClusterConfiguration}"` ([#102071](https://github.com/kubernetes/kubernetes/pull/102071), [@neolit123](https://github.com/neolit123))

These extension points can now be abstracted away due to their irrelevance for most users.

### CSI Migration updates

CSI Migration enables the replacement of existing in-tree storage plugins such as `kubernetes.io/gce-pd` or `kubernetes.io/aws-ebs` with a corresponding CSI driver.
If CSI Migration is working properly, Kubernetes end users shouldn’t notice a difference.

ation-past-present-and-future/), and with the release of v1.25, it has been removed. The updates required to improve its usability would have introduced breaking changes, so it became necessary to remove it in favor of a more friendly replacement. That replacement is [Pod Security Admission](https://kubernetes.io/docs/concepts/security/pod-security-admission/), which graduates to Stable with this release. If you are currently relying on PodSecurityPolicy, please follow the instructions for [migration...
