* The `DefaultFeatureGate` package variable now only exposes readonly feature gate methods. Methods for mutating feature gates have moved into a `MutableFeatureGate` interface and are accessible via the `DefaultMutableFeatureGate` package variable. Only top-level commands and options setup should access `DefaultMutableFeatureGate`. ([#7130...

* The generic RESTClient type (`k8s.io/client-go/rest`) no longer exposes `LabelSelectorParam` or `FieldSelectorParam` methods - use `VersionedParams` with `metav1.ListOptions` instead.  The `UintParam` method has been removed.  The `timeout` parameter will no longer cause an error when using `Param()`.

- Fix a concurrent map access in TopologyCache's `HasPopulatedHints` method. ([#120324](https://github.com/kubernetes/kubernetes/pull/120324), [@Miciah](https://github.com/Miciah)) [SIG Apps and Network]

Eine `FastAPI`-Anwendung (-Instanz) verfügt über eine `.openapi()`-Methode, von der erwartet wird, dass sie das OpenAPI-Schema zurückgibt.

Als Teil der Erstellung des Anwendungsobjekts wird eine *Pfadoperation* für `/openapi.json` (oder welcher Wert für den Parameter `openapi_url` gesetzt wurde) registriert.

Diese gibt lediglich eine JSON-Response zurück, mit dem Ergebnis der Methode `.openapi()` der Anwendung.
