# Über FastAPI-Versionen

**FastAPI** wird bereits in vielen Anwendungen und Systemen produktiv eingesetzt. Und die Testabdeckung wird bei 100 % gehalten. Aber seine Entwicklung geht immer noch schnell voran.

Es werden regelmäßig neue Funktionen hinzugefügt, Fehler werden regelmäßig behoben und der Code wird weiterhin kontinuierlich verbessert.
