The old Keras optimizer will never be deleted, but will not see any
    new feature additions.
    New optimizers (e.g., `Adafactor`) will
    only be implemented based on `tf.keras.optimizers.Optimizer`, the new
    base class.

## Major Features and Improvements

*   `tf.lite`:

    *   New operations supported:
          * tf.unsortedsegmentmin op is supported.

### 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
 - have a new beta version _(and deprecate the previous beta)_.
