- Updated `kube-openapi` to remove invalid defaults: OpenAPI spec no longer includes default of `{}` for certain fields where it did not make sense. ([#120757](https://github.com/kubernetes/kubernetes/pull/120757), [@alexzielenski](https://github.com/alexzielenski))

Setting options in `include_router` still makes sense in some cases, for example, to override or increase configurations from a third party router included in an app. But in a router that is part of a bigger application, it would probably make more sense to add those settings when creating the `APIRouter`.

**In `FastAPI`**

We are going to start from where we left in the previous chapter and increment it.

## About JWT

JWT means "JSON Web Tokens".

It's a standard to codify a JSON object in a long dense string without spaces. It looks like this:

```

```

* **Machine Learning**: Normalmente exige muita multiplicação de matrizes e vetores. Pense numa grande folha de papel com números e multiplicando todos eles juntos e ao mesmo tempo.
