That's why the current versions are still `0.x.x`, this reflects that each version could potentially have breaking changes. This follows the [Semantic Versioning](https://semver.org/) conventions.

You can create production applications with **FastAPI** right now (and you have probably been doing it for some time), you just have to make sure that you use a version that works correctly with the rest of your code.
