- Kubeadm: during "join", don't re-add an etcd member if it already exists in the cluster. ([#92118](https://github.com/kubernetes/kubernetes/pull/92118), [@neolit123](https://github.com/neolit123)) [SIG Cluster Lifecycle]

*   `tf.SavedModel`

    *   Introduced class method `tf.saved_model.experimental.Fingerprint.from_proto(proto)`, which can be used to construct a `Fingerprint` object directly from a protobuf.
    *   Introduced member method `tf.saved_model.experimental.Fingerprint.singleprint()`, which provides a convenient way to uniquely identify a SavedModel.

### Bug Fixes and Other Changes

*   `tf.Variable`
