* Add flag "--include-uninitialized" to kubectl annotate, apply, edit-last-applied, delete, describe, edit, get, label, set. "--include-uninitialized=true" makes kubectl commands apply to uninitialized objects, which by default are ignored if the names of the objects are not provided. "--all" also makes kubectl commands apply to uninitialized objects. Please see the [initializer](https://kubernetes.io/docs/admin/extensible-admission-controllers/) doc for more details. ([#5049...

* When creating a service with annotation: service.beta.kubernetes.io/load-balancer-source-ranges containing multiple source ranges and service.beta.kubernetes.io/azure-shared-securityrule: "false",  the NSG rules will be collapsed.

* Fix issue where on re-registration of device plugin, `allocatable` was not getting updated. This issue makes devices invisible to the Kubelet if device plugin restarts. Only work-around, if this fix is not there, is to restart the kubelet and then start device plugin. ([#63118](https://github.com/kubernetes/kubernetes/pull/63118), [@vikaschoudhary16](htt...

- Kubeadm now makes sure the etcd manifest is regenerated upon upgrade even when no etcd version change takes place ([#94395](https://github.com/kubernetes/kubernetes/pull/94395), [@rosti](https://github.com/rosti)) [SIG Cluster Lifecycle]

- GCE clusters will include some IP ranges that are not used on the public Internet in the list of non-masq IPs. Bumped ip-masq-agent version to v2.3.0 with flag `nomasq-all-reserved-ranges` turned on. ([#77458](https://github.com/kubernetes/kubernetes/pull/77458), [@grayluck](https://github.com/grayluck))

- Kubeadm: add the RootlessControlPlane kubeadm specific feature gate (Alpha in 1.22, disabled by default).
  It can be used to enable an experimental feature that makes the control plane component static Pod containers 

Kubernetes 1.11 also makes it easier to see what's happening, as audit events can now be annotated with information about how an API request was handled:

- Added the latest GCE pinhole firewall feature, which introduces `destination-ranges` in the ingress `firewall-rules`. It restricts access to the backend IPs by allowing traffic through `ILB` or `NetLB` only. This change does **NOT** change the existing `ILB` or `NetLB` behavior.
