# About FastAPI versions

**FastAPI** is already being used in production in many applications and systems. And the test coverage is kept at 100%. But its development is still moving quickly.

New features are added frequently, bugs are fixed regularly, and the code is still continuously improving.

In einem fortgeschrittenen Szenario, bei dem Sie wissen, dass die Abhängigkeit bei jedem Schritt (möglicherweise mehrmals) in derselben Anfrage aufgerufen werden muss, anstatt den zwischengespeicherten Wert zu verwenden, können Sie den Parameter `use_cache=False` festlegen, wenn Sie `Depends` verwenden:

Sie senden ihm ein Token und er gibt einen authentifizierten Benutzer zurück.

Dieser Anbieter berechnet Ihnen möglicherweise Gebühren pro Anfrage, und der Aufruf könnte etwas länger dauern, als wenn Sie einen vordefinierten Scheinbenutzer für Tests hätten.
