*  Support for Python 3.7 has been removed. We are not releasing any more patches for Python 3.7.

*   `tf.lite`:

    *   Add 16-bit float type support for built-in op `fill`.
    *   Transpose now supports 6D tensors.
    *   Float LSTM now supports diagonal recurrent tensors: https://arxiv.org/abs/1903.08023

*   `tf.experimental.dtensor`:

For example:

```Python
from contextlib import asynccontextmanager

from fastapi import FastAPI


def fake_answer_to_everything_ml_model(x: float):
    return x * 42


ml_models = {}


@asynccontextmanager
async def lifespan(app: FastAPI):
    # Load the ML model
