These last **three consecutive releases** are independent so that you can **migrate gradually**:

* First to FastAPI `0.68.2`, with no breaking changes, but upgrading all the sub-dependencies.
* Next to FastAPI `0.69.0`, which upgrades Starlette to `0.15.0`, with AnyIO support, and a higher chance of having breaking changes in your code.

# Middleware { #middleware }

Vous pouvez ajouter des middlewares aux applications **FastAPI**.

Un « middleware » est une fonction qui agit sur chaque **requête** avant qu’elle ne soit traitée par un *chemin d'accès* spécifique. Et aussi sur chaque **réponse** avant son renvoi.

* Il intercepte chaque **requête** qui parvient à votre application.
* Il peut alors faire quelque chose avec cette **requête** ou exécuter tout code nécessaire.

FastAPI (en fait Starlette) inclura automatiquement un en-tête Content-Length. Il inclura aussi un en-tête Content-Type, basé sur `media_type` et en ajoutant un charset pour les types textuels.
