- Added Coordinated Leader Election as Alpha under the `CoordinatedLeaderElection` feature gate. With the feature enabled, the control plane can use LeaseCandidate objects (coordination.k8s.io/v1alpha1 API group) to participate in a leader election and let the kube-apiserver select the best instance according to some strategy.

* `deployments/rollback` is now passed through validation/admission controllers ([#72271](https://github.com/kubernetes/kubernetes/pull/72271), [@jhrv](https://github.com/jhrv))
* The `Lease` API type in the `coordination.k8s.io` API group is promoted to `v1` ([#72239](https://github.com/kubernetes/kubernetes/pull/72239), [@wojtek-t](https://github.com/wojtek-t))

in the `kubelet` on driver mismatch (kubeadm clusters should be using the `systemd` driver). Also remove the `IsDockerSystemdCheck` preflight check (warning) that checks if the Docker cgroup driver is set to `systemd`. Ideally such detection / coordination should be on the side of CRI implementers and the kubelet (tracked [here](https://github.com/kubernetes/kubernetes/issues/99808)). Please see the [page](https://kubernetes.io/docs/tasks/administer-cluster/kubeadm/configure-cgroup-driver/) on how...

- The namespace editors and admins can now create leases.coordination.k8s.io and should use this type for leaderelection instead of configmaps. ([#111472](https://github.com/kubernetes/kubernetes/pull/111472), [@deads2k](https://github.com/deads2k))

- Autoscaling/v2beta1 is deprecated in favor of autoscaling/v2beta2 ([#90463](https://github.com/kubernetes/kubernetes/pull/90463), [@deads2k](https://github.com/deads2k)) [SIG Autoscaling]
- Coordination.k8s.io/v1beta1 is deprecated in 1.19, targeted for removal in 1.22, use v1 instead. ([#90559](https://github.com/kubernetes/kubernetes/pull/90559), [@deads2k](https://github.com/deads2k)) [SIG Scalability]
