- It can be used to provide scratch storage that is different from the root disk, for example persistent memory, or a separate local disk on that node.
 - All StorageClass parameters for volume provisioning are supported.
 - All features supported with PersistentVolumeClaims are supported, such as storage capacity tracking, snapshots and restore, and volume resizing.

*   Issues a warning when the `session_config` parameter for the TF1 converter
    is used or the `rewrite_config_template` field in the TF2 converter
    parameter object is used.

### TPU Enhancements:

*   Adds support for the `beta` parameter of the FTRL optimizer for TPU
    embeddings. Users of other TensorFlow platforms can implement equivalent
    behavior by adjusting the `l2` parameter.

### XLA Support:
