### Deployment
* **[beta]** Deployments that cannot make progress in rolling out the newest version will now indicate via the API they are blocked ([docs](https://kubernetes.io/docs/user-guide/deployments/#deployment-status))

### Federation

* new dhcp-domain parameter to be used for figuring out the hostname of a node ([#61890](https://github.com/kubernetes/kubernetes/pull/61890), [@dims](https://github.com/dims))
* Extend the Stackdriver Metadata Agent by adding a new Deployment for ingesting unscheduled pods, and services.   ([#62043](https://github.com/kubernetes/kubernetes/pull/62043), [@supriyagarg](https://github.com/supriyagarg))

* Deployment will stop adding pod-template-hash labels/selector to ReplicaSets and Pods it adopts. Resources created by Deployments are not affected (will still have pod-template-hash labels/selector).  ([#61615](https://github.com/kubernetes/kubernetes/pull/61615), [@janetkuo](https://github.com/janetkuo))

### Feature

- 'kubeadm: enhanced the "patches" functionality to be able to patch coredns
  deployment. The new patch target is called "corednsdeployment" (e.g. patch file
  "corednsdeployment+json.json"). This makes it possible to apply custom patches

#### AWS

- The `system:aws-cloud-provider` cluster role, deprecated in v1.13, is no longer auto-created. Deployments using the AWS cloud provider should grant required permissions to the `aws-cloud-provider` service account in the `kube-system` namespace as part of deployment.  ([#66635](https://github.com/kubernetes/kubernetes/pull/66635), [@wgliang](https://github.com/wgliang))

#### Azure

- Promoted ReplicaSet and Deployment `.status.terminatingReplicas` tracking to beta. The `DeploymentReplicaSetTerminatingReplicas` feature gate is now enabled by default. ([#133087](https://github.com/kubernetes/kubernetes/pull/133087), [@atiratree](https://github.com/atiratree)) [SIG...

- Kube-controller-manager: Fixes bug setting headless service labels on endpoints ([#85361](https://github.com/kubernetes/kubernetes/pull/85361),...

### 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]

With cluster-wide seccomp defaults, the kubelet uses the `RuntimeDefault` seccomp profile by default, rather than than `Unconfined`. This allows enhancing the default cluster wide workload security of the Kubernetes deployment. Security administrators will now sleep better knowing there is some security by default for the workloads.

- When describing deployments, `OldReplicaSets` now always shows all replicasets controlled the deployment, not just those that still have replicas available. ([#113083](https://github.com/kubernetes/kubernetes/pull/113083), [@llorllale](https://github.com/llorllale)) [SIG CLI]
