- DRA: When the prioritized list feature was used in a request and the resulting number of allocated devices exceeded the number of allowed devices per claim, the scheduler aborted the attempt to allocate devices early. Previously, it tried to many different combinations, which could take a long time.

- kubelet: change `node-lease-renew-interval` to 0.25 of lease-renew-duration ([#80429](https://github.com/kubernetes/kubernetes/pull/80429), [@gaorong](https://github.com/gaorong))
- Attempt to set the kubelet's hostname & internal IP if `--cloud-provider=external` and no node addresses exists ([#75229](https://github.com/kubernetes/kubernetes/pull/75229), [@andrewsykim](https://github.com/andrewsykim))

### Scheduling

    *   Add determinism-unimplemented exception-throwing to the following ops.
        When op-determinism is expected (i.e. after
        `tf.config.experimental.enable_op_determinism` has been called), an
        attempt to use the specified paths through the following ops on a GPU
        will cause `tf.errors.UnimplementedError` (with an understandable
        message), unless otherwise specified, to be thrown.

- DRA: when a DRA driver was started after creating pods which need resources from that driver, no additional attempt was made to schedule such unschedulable pods again. Only affected DRA with structured parameters. ([#126807](https://github.com/kubernetes/kubernetes/pull/126807), [@pohly](https://github.com/pohly)) [SIG Node, Scheduling and Testing]

  Presently the Rabbit came up to the door, and tried to open it;
but, as the door opened inwards, and Alice's elbow was pressed
hard against it, that attempt proved a failure.  Alice heard it
say to itself `Then I'll go round and get in at the window.'

  `THAT you won't' thought Alice, and, after waiting till she
fancied she heard the Rabbit just under the window, she suddenly

For stable features, the `kubectl` tool follows the Kubernetes [version skew policy](https://kubernetes.io/releases/version-skew-policy/);
however, kubectl v1.21 and older do not support the new API for ephemeral containers.
