**FastAPI** est déjà utilisé en production dans de nombreuses applications et systèmes. Et la couverture de test est maintenue à 100 %. Mais son développement est toujours aussi rapide.

C'est pourquoi les versions actuelles sont toujours `0.x.x`, cela reflète que chaque version peut potentiellement
