  1. RELEASE.md

    *   API changes under `tf.experimental.dtensor`:
        *   New API for initialization of CPU/GPU/TPU in dtensor.
            `dtensor.initialize_accelerator_system` and
            `dtensor.shutdown_accelerator_system`.
        *   The following existing API will be removed:
            `dtensor.initialize_multi_client`, `dtensor.initialize_tpu_system`, and
            `dtensor.shutdown_tpu_system`.
