- This PR added tracing support to the kubelet's read-only endpoint, which currently
  does not have tracing. It makes use of the `WithPublicEndpoint` option to prevent callers
  from influencing sampling decisions. ([#121770](https://github.com/kubernetes/kubernetes/pull/121770), [@frzifus](https://github.com/frzifus)) [SIG Node]

- The e2e suite can be instructed not to wait for pods in kube-system to be ready or for all nodes to be ready by passing `--allowed-not-ready-nodes=-1` when invoking the e2e.test program. This allows callers to run subsets of the e2e suite in scenarios other than perfectly healthy clusters. ([#98781](https://github.com/kubernetes/kubernetes/pull/98781), [@smarterclayton](https://github.com/smarterclayton)) [SIG Testing]

- Informer/reflector callers can now catch and unwrap specific API errors by type. ([#110076](https://github.com/kubernetes/kubernetes/pull/110076), [@karlkfi](https://github.com/karlkfi))

- Bump runc to v1.1.4. ([#113719](https://github.com/kubernetes/kubernetes/pull/113719), [@pacoxu](https://github.com/pacoxu))
- Callers using `DelegatingAuthenticationOptions` can now use `DisableAnonymous` to disable Anonymous authentication. ([#112181](https://github.com/kubernetes/kubernetes/pull/112181), [@xueqzhan](https://github.com/xueqzhan))

- `(*"k8s.io/client-go/rest".Request).{Do,DoRaw,Stream,Watch}` now require callers to pass a `context.Context` as an argument. The context is used for timeout and cancellation signaling and to pass supplementary information to round trippers in the wrapped transport chain. If you don't need any of this functionality, it is sufficient...

    bus indexing now starts from 1 instead of 0, and `bus_id==0` is used where
    previously `BUS_ANY` was used.
*   `Env::FileExists` and `FileSystem::FileExists` now return a
    tensorflow::Status instead of a bool. Any callers to this function can be
    converted to a bool by adding .ok() to the call.
*   The C API type `TF_SessionWithGraph` has been renamed to `TF_Session`,

(if the server supports it) will be of type `meta.k8s.io/v1alpha1` with `Table`, and contain column and row information related to the resource.  Each row will contain information about the resource - by default it will be the object metadata, but callers can add the `?includeObject=Object` query parameter and receive the full object.  In the future kubectl will use this to retrieve the results of `kubectl get`. ([#40848](https://github.com/kubernetes/kubernetes/pull/40848), [@smarterclayton](http...

The <code>protect</code> function in the example below invokes
the function argument <code>g</code> and protects callers from
run-time panics caused by <code>g</code>.
