### SIG Openstack

  set to true, the system will guarantee scheduling and admission of pods with
  the following annotation - `scheduler.alpha.kubernetes.io/critical-pod`
  - This feature should be used in conjunction with the
    [rescheduler](https://kubernetes.io/docs/admin/rescheduler/) to guarantee
    resource availability for critical system pods.
* **[alpha]** `--experimental-nvidia-gpus` flag is replaced by `Accelerators` alpha

      the vocabulary lookup tensor is updated at the time interval set in the
      `UpdateEmbeddingCallback` based on the most up-to-date vocabulary hash
      table maintained by the layer. If this layer is not used in conjunction
      with `UpdateEmbeddingCallback` the behavior of the layer would be same as
      `keras.layers.Embedding`.
*  `keras.optimizers.Adam`
    * Added the option to set adaptive epsilon to match implementations with Jax
