*   Upgrading the kubernetes-master units now results in staged upgrades just like the kubernetes-worker nodes. Use the upgrade action in order to continue the upgrade process on each unit such as juju run-action kubernetes-master/0 upgrade ([#55990](https://github.com/kubernetes/kubernetes/pull/55990),[ @hyperbolic2346](https://github.com/hyperbolic2346))

    *   The protocol used for Estimator training is now configurable in
        RunConfig.
    *   Triangular solve performance improvements.
    *   Unify RNN cell interface between TF and Keras. Add new
        get_initial_state() to Keras and TF RNN cell, which will use to replace
        the existing zero_state() method.
    *   Update initialization of variables in Keras.

  returns `nil`. (It now returns a pointer to a zero-valued object, like the real
  clients do.) This will break some downstream unit tests that were testing
  `result == nil` rather than `err != nil`, and in some cases may expose bugs
