## Dependencies

`tf.divide()` is now the recommended division function. `tf.div()` will remain,
but its semantics do not respond to Python 3 or `from future` mechanisms. *
tf.reverse() now takes indices of axes to be reversed. E.g. `tf.reverse(a,
[True, False, True])` must now be written as `tf.reverse(a, [0, 2])`.
`tf.reverse_v2()` will remain until 1.0 final. * `tf.mul`, `tf.sub` and `tf.neg`

### Avoiding permanent beta

From Kubernetes 1.20 onwards, SIG Architecture will implement a new policy to transition all REST APIs out of beta within nine months. The idea behind the new policy is to avoid features staying in beta for a long time. Once a new API enters beta, it will have nine months to either:

 - reach GA, and deprecate the beta, or

### etcd moves to version 3.5.0

* Interaction with container runtimes is now through the CRI interface, enabling easier integration of runtimes with the kubelet. Docker remains the default runtime via Docker-CRI (which moves to beta).
  * **WARNING:** A [known issue](https://github.com/kubernetes/kubernetes/issues/44041)
