### Refactors

* 🎨 Fix typing annotation for semi-internal `FastAPI.add_api_route()`. PR [#10240](https://github.com/fastapi/fastapi/pull/10240) by [@ordinary-jamie](https://github.com/ordinary-jamie).
* ⬆️ Upgrade version of Ruff and reformat. PR [#12032](https://github.com/fastapi/fastapi/pull/12032) by [@tiangolo](https://github.com/tiangolo).

### Docs

*   Large cleanup to add second order gradient for ops with C++ gradients and
    improve existing gradients such that most ops can now be differentiated
    multiple times.
*   Added a solver for ordinary differential equations,
    `tf.contrib.integrate.odeint`.
*   New contrib module for tensors with named axes, `tf.contrib.labeled_tensor`.
*   Visualization of embeddings in TensorBoard.
