* `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))

- 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...

* 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))

- 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]

- 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.
