* Adds a new `kubeadm config` command that lets users tell `kubeadm upgrade` what kubeadm configuration to use and lets users view the current state. ([#50980](https://github.com/kubernetes/kubernetes/pull/50980), [@luxas](https://github.com/luxas))

  // Traffic intended for the service should be sent to these ingress points.
  // +optional
  repeated LoadBalancerIngress ingress = 1;
}

// LocalObjectReference contains enough information to let you locate the
// referenced object inside the same namespace.
// +structType=atomic
message LocalObjectReference {
  // Name of the referent.

- Added a new command line argument `--interactive` to kubectl. The new command line argument lets a user confirm deletion requests per resource interactively. ([#114530](https://github.com/kubernetes/kubernetes/pull/114530), [@ardaguclu](https://github.com/ardaguclu)) [SIG CLI and Testing]

  - warn - perform server-side validation and warn on any invalid fields (but ultimately let the request succeed by dropping any invalid fields from the object). If validation is not available on the server, perform no validation.
