## Version 5.0.0

_2025-07-02_

This is our first stable release of OkHttp since 2023. Here's the highlights if you're upgrading
from OkHttp 4.x:

**OkHttp is now packaged as separate JVM and Android artifacts.** This allows us to offer

#### Using `Union` or `Optional` { #using-union-or-optional }

If you are using a Python version below 3.10, here's a tip from my very **subjective** point of view:

* 🚨 Avoid using `Optional[SomeType]`
* Instead ✨ **use `Union[SomeType, None]`** ✨.

FastAPI est un framework web moderne et rapide (haute performance) pour la création d'API avec Python, basé sur les annotations de type standard de Python.

Les principales fonctionnalités sont :

* **Rapidité** : De très hautes performances, au niveau de **NodeJS** et **Go** (grâce à Starlette et Pydantic). [L'un des frameworks Python les plus rapides](#performance).

Aber wenn Sie in diesem Fall die acht Ex-Kassierer/Köche/jetzt Reinigungskräfte mitbringen würden und jeder von ihnen (plus Sie) würde einen Bereich des Hauses reinigen, könnten Sie die ganze Arbeit **parallel** erledigen, und würden mit dieser zusätzlichen Hilfe viel schneller fertig werden.

Il nécessite une configuration un peu plus verbeuse. Et comme il est basé sur WSGI (au lieu dASGI), il n'est pas
conçu pour profiter des hautes performances fournies par des outils comme Uvicorn, Starlette et Sanic.
