- Output for the `ScalingReplicaSet` event has changed from:
      Scaled <up|down> replica set <replica-set-name> to <new-value> from <old-value>
  to:
      Scaled <up|down> replica set <replica-set-name> from <old-value> to <new-value>. ([#125118](https://github.com/kubernetes/kubernetes/pull/125118), [@jsoref](https://github.com/jsoref)) [SIG Apps and CLI]

- When scaling down a ReplicaSet, delete doubled up replicas first, where a "doubled up replica" is defined as one that is on the same node as an active replica belonging to a related ReplicaSet.  ReplicaSets are considered "related" if they have a common controller (typically a Deployment). ([#80004](https://github.com/kubernetes/kubernetes/pull/80004), [@Miciah](https:/...

- Allow for configuration of CoreDNS replica count ([#85837](https://github.com/kubernetes/kubernetes/pull/85837), [@pickledrick](https://github.com/pickledrick)) [SIG Cluster Lifecycle]

- 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]
- Fixed a bug that fails to create a replica set when a deployment name is too long. ([#132560](https://github.com/kubernetes/kubernetes/pull/132560), [@hdp617](https://github.com/hdp617)) [SIG API Machinery and Apps]

- To avoid soft-deleted pods incorrectly affecting scale up replica count calculations, the HPA controller will stop counting soft-deleted pods for scaling purposes. ([#67067](https://github.com/kubernetes/kubernetes/pull/67067), [@moonek](https://github.com/moonek))

- Fixed StatefulSet to show the valid status even if the new replica creation fails. ([#112084](https://github.com/kubernetes/kubernetes/pull/112084), [@gjkim42](https://github.com/gjkim42)) [SIG Apps and Testing]

- Fixed StatefulSet to show the valid status even if the new replica creation fails. ([#112083](https://github.com/kubernetes/kubernetes/pull/112083), [@gjkim42](https://github.com/gjkim42)) [SIG Apps and Testing]
