*   Unified eager and `tf.function` execution:

    *   Eager mode can now execute each op as a `tf.function`, allowing for more
        consistent feature support in future releases.
    *   It is available for immediate use.
        *   See the `TF_RUN_EAGER_OP_AS_FUNCTION` environment variable in

    * New docs: [Dependencies with `yield` - Early exit and `scope`](https://fastapi.tiangolo.com/tutorial/dependencies/dependencies-with-yield/#early-exit-and-scope).
