Debido a eso, las versiones de FastAPI anteriores a 0.99.0 todavía usaban versiones de OpenAPI menores a 3.1.0.

#### Neuere Python-Versionen

Die Syntax, welche `typing` verwendet, ist **kompatibel** mit allen Versionen, von Python 3.6 aufwärts zu den neuesten, inklusive Python 3.9, Python 3.10, usw.

`xl.meta` carries three types of object entries which designate the type of version object stored.

- ObjectType (default)
- LegacyObjectType (preserves existing deployments and older xl.json format)
- DeleteMarker (a versionId to capture the DELETE sequences implemented primarily for AWS spec compatibility)
