### Bug or Regression

- (PodSecurity admission) errors validating workload resources (deployment, replicaset, etc.) no longer block admission. ([#106017](https://github.com/kubernetes/kubernetes/pull/106017), [@tallclair](https://github.com/tallclair)) [SIG Auth]

* federation: Adding support for DeleteOptions.OrphanDependents for federated replicasets and deployments. Setting it to false while deleting a federated replicaset or deployment also deletes the corresponding resource from all registered clusters. ([#36476](https://github.com/kubernetes/kubernetes/pull/36476), [@nikhiljindal](https://github.com/nikhiljindal))

* `make test-cmd` now works on OSX. ([#61393](https://github.com/kubernetes/kubernetes/pull/61393), [@totherme](https://github.com/totherme))
* Conformance: ReplicaSet must be supported in the `apps/v1` version. ([#61367](https://github.com/kubernetes/kubernetes/pull/61367), [@enisoc](https://github.com/enisoc))

* fix typo  ([#59619](https://github.com/kubernetes/kubernetes/pull/59619), [@jianliao82](https://github.com/jianliao82))

* DaemonSet, Deployment, ReplicaSet, and StatefulSet objects are now persisted in etcd in apps/v1 format ([#58854](https://github.com/kubernetes/kubernetes/pull/58854), [@liggitt](https://github.com/liggitt))

- Reduced log verbosity for high-frequency, low-value log entries in Job, IPAM, and ReplicaSet controllers by adjusting them to V(2), V(4) and V(4) respectively. This change minimizes log noise while maintaining access to these logs when needed. ([#130591](https://github.com/kubernetes/kubernetes/pull/130591), [@fmuyassarov](https://gith...

- Fixed a bug that caused duplicate validation when updating a ReplicaSet. ([#131873](https://github.com/kubernetes/kubernetes/pull/131873), [@gavinkflam](https://github.com/gavinkflam)) [SIG Apps]

- Migrated the `ReplicaSet` controller (within `kube-controller-manager`) to use [contextual logging](https://k8s.io/docs/concepts/cluster-administration/system-logs/#contextual-logging). ([#114871](https://github.com/kubernetes/kubernetes/pull/114871), [@Namanl2001](htt...

- Track ownership of scale subresource for all scalable resources i.e. Deployment, ReplicaSet, StatefulSet, ReplicationController, and Custom Resources. ([#98377](https://github.com/kubernetes/kubernetes/pull/98377), [@nodo](https://github.com/nodo)) [SIG API Machinery and Testing]

### Feature

  - DaemonSet, Deployment, and ReplicaSet resources will no longer be served from `extensions/v1beta1`, `apps/v1beta1`, or `apps/v1beta2` in v1.16. Migrate to the `apps/v1` API, available since v1.9. Existing persisted data can be retrieved via the `apps/v1` API.
