### `TensorRT`

*   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.
