# À propos des versions de FastAPI { #about-fastapi-versions }

**FastAPI** est déjà utilisé en production dans de nombreuses applications et de nombreux systèmes. Et la couverture de tests est maintenue à 100 %. Mais son développement avance toujours rapidement.

De nouvelles fonctionnalités sont ajoutées fréquemment, des bogues sont corrigés régulièrement et le code s'améliore continuellement.

Upgrade Checklist - Test all upgrades in a lower environment (DEV, QA, UAT) before applying to production. Performing blind upgrades in production environments carries significant risk. - Read the release notes for MinIO *before* performing any upgrade, there is no forced requirement to upgrade to latest release upon every release. Some release may not be relevant to your setup, avoid upgrading production environments unnecessarily. - If you plan to use `mc admin update`, MinIO process must have write...
