- kubeadm: graduated the WaitForAllControlPlaneComponents feature gate to Beta. When checking the health status of a control plane component, make sure that the address and port defined as arguments in the respective component's static Pod manifest are used.

- Forbidden sysctls for pod sharing the respective namespaces with the host are now checked when creating or updating pods without such sysctls. ([#118705](https://github.com/kubernetes/kubernetes/pull/118705), [@pacoxu](https://github.com/pacoxu))

- Kubectl now supports shell completion for the <type>/<name> format for specifying resources.

We are also continuing our long running effort to extract all the existing cloud providers that live in k8s.io/kubernetes into their own respective repos. Along with this migration, we are slowly transitioning users to use the cloud-controller-manager for any cloud provider features instead of the kube-controller-manager.

(used to opt in to isolation) has been removed. Instead, isolation is now determined on a per-pod basis. A NetworkPolicy may target a pod for isolation by including the pod in its spec.podSelector. Targeted Pods accept the traffic specified in the respective NetworkPolicy (and nothing else). Pods not targeted by any NetworkPolicy accept all traffic by default.

generated clientsets, dynamic, metadata, and scale clients have been modified to accept `context.Context` as a first argument. Signatures of Create, Update, and Patch methods have been updated to accept CreateOptions, UpdateOptions and PatchOptions respectively. Signatures of Delete and DeleteCollection methods now accept DeleteOptions by value instead of by reference. Generated clientsets with the previous interface have been added in new "deprecated" packages to allow incremental migration to the new...

- kubelet now accepts `pid=<number>` in the `--system-reserved` and `--kube-reserved` options to ensure that the specified number of process IDs will be reserved for the system as a whole and for Kubernetes system daemons respectively.  Please reference `Kube Reserved` and `System Reserved` in `Reserve Compute Resources for System Daemons` in the Kubernetes documentation for general discussion of resource reservation.  To utilize this functionality, you must set the feature...

  So, if you want to just keep the existing behavior, you can register `ClusterEventWithHint` with no `QueueingHintFn` in it. 
  But, registering appropriate `QueueingHintFn` is, of course, better from a scheduling performance perspective. ([#118551](https://github.com/kubernetes/kubernetes/pull/118551), [@sanposhiho](https://github.com/sanposhiho)) [SIG Node, Scheduling, Storage and Testing]

  * `.NodeName` and `.CRISocket` in the `MasterConfiguration` and `NodeConfiguration` v1alpha1 API objects are now `.NodeRegistration.Name` and `.NodeRegistration.CRISocket` respectively in the v1alpha2 API. The `.NoTaintMaster` field has been removed in the v1alpha2 API. ([#64210](https://github.com/kubernetes/kubernetes/pull/64210), [@luxas](https://github.com/luxas))
