- Kubeadm: removed the deprecated `v1beta2` API. kubeadm 1.26's `config migrate`
  command can be used to migrate a `v1beta2` configuration file to `v1beta3` ([#114540](https://github.com/kubernetes/kubernetes/pull/114540), [@pacoxu](https://github.com/pacoxu))

 * addressed by the new {@link java.util.stream.Stream} library. Read the method documentation below

 * streams.

- API
  - Ingress resources will no longer be served from `extensions/v1beta1` in v1.19. Migrate use to the `networking.k8s.io/v1beta1` API, available since v1.14. Existing persisted data can be retrieved via the `networking.k8s.io/v1beta1` API.

  - The "ClusterConfiguration.timeoutForControlPlane" field has been replaced by "{Init|Join}Configuration.timeouts.controlPlaneComponentHealthCheck".
  Please use the command "kubeadm config migrate" to migrate your existing v1beta3 configuration to v1beta4.
  
  v1beta3 is now marked as deprecated but will continue to be supported until version 1.34 or later.

Because the release includes breaking API changes, we're changing the project's
package name from `com.squareup.okhttp` to `okhttp3`. This should make it
possible for large applications to migrate incrementally. The Maven group ID
is now `com.squareup.okhttp3`. For an explanation of this strategy, see Jake
Wharton's post, [Java Interoperability Policy for Major Version
Updates][major_versions].

    * Additionally, LiteRT code base will decouple from TensorFlow repository, and `tf.lite` will be removed in future TensorFlow Python package. More details to follow in future release notes.
    * Migrate to LiteRT for continued updates; the new repo can be found at https://github.com/google-ai-edge/LiteRT.  For more information and NPU EAP signup, reach out to the team at: [g.co/ai/LiteRT-NPU-EAP](https://g.co/ai/LiteRT-NPU-EAP).

- If upgrading Cluster Federation components from 1.3.x, be aware the federation-controller-manager now looks for a different secret name.  Run the following to migrate (#28938, @madhusudancs)

```
kubectl --namespace=federation get secret federation-apiserver-secret -o json | sed 's/federation-apiserver-secret/federation-apiserver-kubeconfig/g' | kubectl create -f -
