# À propos des versions de FastAPI

**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.

De nouvelles fonctionnalités sont ajoutées fréquemment, des bogues sont corrigés régulièrement et le code est
amélioré continuellement.

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

<a href="https://developer.mozilla.org/en-US/docs/Web/HTTP/CORS" class="external-link" target="_blank">CORS or "Cross-Origin Resource Sharing"</a> refers to the situations when a frontend running in a browser has JavaScript code that communicates with a backend, and the backend is in a different "origin" than the frontend.

# CORS (Обмін ресурсами між різними джерелами)

<a href="https://developer.mozilla.org/en-US/docs/Web/HTTP/CORS" class="external-link" target="_blank">CORS або "Обмін ресурсами між різними джерелами"</a> є ситуація, коли фронтенд, що працює в браузері, містить JavaScript-код, який взаємодіє з бекендом, розташованим в іншому "джерелі" (origin).

## Джерело (Origin)

/// info

FastAPI a ajouté le support pour `Annotated` (et a commencé à le recommander) dans la version 0.95.0.

Si vous avez une version plus ancienne, vous obtiendrez des erreurs en essayant d'utiliser `Annotated`.

Assurez-vous de [Mettre à jour la version de FastAPI](../deployment/versions.md#upgrading-the-fastapi-versions){.internal-link target=_blank} à la version 0.95.1 à minima avant d'utiliser `Annotated`.

# CORS (Cross-Origin Resource Sharing)

<a href="https://developer.mozilla.org/en-US/docs/Web/HTTP/CORS" class="external-link" target="_blank">CORS ou "Cross-Origin Resource Sharing"</a> refere-se às situações em que um frontend rodando em um navegador possui um código JavaScript que se comunica com um backend, e o backend está em uma "origem" diferente do frontend.

## Origem
