- `kubeadm.k8s.io/v1beta2` has been deprecated and will be removed in a future release, possibly in 3 releases (one year). You should start using `kubeadm.k8s.io/v1beta3` for new clusters. To migrate your old configuration files on disk you can use the `kubeadm config migrate` command. ([#107013](https://github.com/kubernetes/kubernetes/pull/107013), [@pacoxu](https://github.com/pacoxu))

- 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))

- Migrate Memory Manager to contextual logging ([#130727](https://github.com/kubernetes/kubernetes/pull/130727), [@swatisehgal](https://github.com/swatisehgal)) [SIG Node]
- Migrate pkg/kubelet/volumemanager to contextual logging ([#131306](https://github.com/kubernetes/kubernetes/pull/131306), [@Chulong-Li](https://github.com/Chulong-Li)) [SIG Node]

* The deprecated `ThirdPartyResource` (TPR) API was removed.
  To avoid losing your TPR data, [migrate to CustomResourceDefinition](https://kubernetes.io/docs/tasks/access-kubernetes-api/migrate-third-party-resource/).

* The following deprecated flags were removed from `kube-controller-manager`:

  * `replication-controller-lookup-cache-size`

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

  - The "ClusterConfiguration.timeoutForControlPlane" field has been replaced by "{Init|Join}Configuration.timeouts.controlPlaneComponentHealthCheck".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.

- 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.

    * 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).

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].
