### CVE-2021-25735: Validating Admission Webhook does not observe some previous fields

A security issue was discovered in kube-apiserver that could allow node
updates to bypass a Validating Admission Webhook. You are only affected
by this vulnerability if you run a Validating Admission Webhook for Nodes
that denies admission based at least partially on the old state of the
Node object.

    *   Add TensorSpec to represent the specification of Tensors.
    *   Constant folding pass is now deterministic.
    *   Support `float16` `dtype` in `tf.linalg.*`.
    *   Add `tf.estimator.export.TensorServingInputReceiver` that allows
        `tf.estimator.Estimator.export_savedmodel` to pass raw tensors to model
        functions.

## Deprecations

In short, if you had dependencies that looked like:

```Python
def my_dep():
    try:
        yield
    except SomeException:
        pass
```

Now you need to make sure you raise again after `except`, just as you would in regular Python:

```Python
def my_dep():
    try:
        yield
    except SomeException:
