* Federation control plane can be upgraded by updating the image
fields in the `Deployment` specs of the control plane components.
However, federation control plane upgrades were not tested in this
release [38537](https://github.com/kubernetes/kubernetes/issues/38537)

## Notable Changes to Existing Behavior

* Conformance tests are added for the DaemonSet kinds in the apps/v1 group version. Deprecated versions of DaemonSet will not be tested for conformance, and conformance is only applicable to release 1.10 and later. ([#60456](https://github.com/kubernetes/kubernetes/pull/60456), [@kow3ns](https://github.com/kow3ns))

- E2e framework: the `node-role.kubernetes.io/master` taint has been removed from the default value of `--non-blocking-taints` flag. You may need to set `--non-blocking-taints` explicitly if the cluster to be tested has nodes with the deprecated `node-role.kubernetes.io/master` taint. ([#118510](https://github.com/kubernetes/kubernetes/pull/118510), [@SataQiu](https://github.com/SataQiu)) [SIG Testing]

    *   Relies on CNI 0.6.0 binaries for IPv6 pod networking.
    *   Adds IPv6 support for kube-dns using SRV records.
    *   Caveats
        *   Only the CNI bridge and local-ipam plugins have been tested for the alpha release, although other CNI plugins do support IPv6.
        *   HostPorts are not supported.

    *   They are off by default. Enable them by setting the environment variable
        `TF_ENABLE_ONEDNN_OPTS=1`.
    *   We do not recommend using them in GPU systems, as they have not been
        sufficiently tested with GPUs yet.
*   TensorFlow pip packages are now built with CUDA11.2 and cuDNN 8.1.0

## Breaking Changes

*   The `TF_CPP_MIN_VLOG_LEVEL` environment variable has been renamed to

initialize a temporary variable <code>t</code> without explicit type; it is that
value of <code>t</code> against which each case expression <code>x</code> is tested
for equality.
