- The `RemoteRequestHeaderUID` feature moves to beta and is now enabled by default. This makes the kube-apiserver propagate UIDs in the `X-Remote-Uid` header in requests to the aggregated API servers. The header is not honored by default for incoming requests, but that can be enabled by setting the `--requestheader-uid-headers` flag explicitly. ([#130560](https://git...

- Changed underlying logic to propagate pod-level hugepage cgroup to containers when they did not specify hugepage resources.

- Removed scheduler names from preemption event messages. ([#114980](https://github.com/kubernetes/kubernetes/pull/114980), [@mimowo](https://github.com/mimowo))

*  TensorFlow IO support is now available for Apple Silicon packages.

*  Refactor CpuExecutable to propagate LLVM errors.

## Keras

Keras is a framework built on top of the TensorFlow. See more details on the Keras [website](https://keras.io/).

### Major Features and Improvements

* `tf.keras`

* [Federation] Remove FEDERATIONS_DOMAIN_MAP references ([#43137](https://github.com/kubernetes/kubernetes/pull/43137), [@shashidharatd](https://github.com/shashidharatd))
* Fix for [federation failing to propagate cascading deletion](https://github.com/kubernetes/kubernetes/issues/44304). ([#44108](https://github.com/kubernetes/kubernetes/pull/44108), [@csbell](https://github.com/csbell))

  * The `VolumeMount.Propagation` field for `VolumeMount` in pod containers is now available.

  * You can now set `VolumeMount.Propagation` to `Bidirectional` to enable a particular mount for a container to propagate itself to the host or other containers.

* [alpha] Improve Flex volume deployment

  * Flex volume driver deployment is simplified in the following ways:

* Fix for [federation failing to propagate cascading deletion](https://github.com/kubernetes/kubernetes/issues/44304). ([#44108](https://github.com/kubernetes/kubernetes/pull/44108), [@csbell](https://github.com/csbell))
