- Users might specify the `kubectl.kubernetes.io/default-exec-container` annotation in a Pod to preselect container for kubectl commands. ([#97099](https://github.com/kubernetes/kubernetes/pull/97099), [@pacoxu](https://github.com/pacoxu)) [SIG CLI]

### Feature

// hook. One and only one of the fields, except TCPSocket must be specified.
message LifecycleHandler {
  // Exec specifies the action to take.
  // +optional
  optional ExecAction exec = 1;

  // HTTPGet specifies the http request to perform.
  // +optional
  optional HTTPGetAction httpGet = 2;

- Kubelet metrics have been changed to buckets. 
  For example the exec/{podNamespace}/{podID}/{containerName} is now just exec. ([#87913](https://github.com/kubernetes/kubernetes/pull/87913), [@cheftako](https://github.com/cheftako)) [SIG Node]

## Urgent Upgrade Notes 

### (No, really, you MUST read this before you upgrade)

### Bug or Regression

- Fix an ephemeral port exhaustion bug caused by improper connection management that occurred when a large number of objects were handled by kubectl while exec auth was in use. ([#112337](https://github.com/kubernetes/kubernetes/pull/112337), [@enj](https://github.com/enj)) [SIG API Machinery and Auth]

* Fixed regression in initial kubectl exec terminal dimensions ([#51127](https://github.com/kubernetes/kubernetes/pull/51127), [@chen-anders](https://github.com/chen-anders))
