- Dynamic Resource Allocation (DRA): using structured parameters with a claim that gets reused between pods may have led to a claim with an invalid state (allocated without a finalizer) which then caused scheduling of pods using the claim to stop.

- Graduated the `LegacyServiceAccountTokenTracking` feature gate to GA. The usage of auto-generated secret-based service account token now produces warnings, and relevant Secrets are labeled with a last-used timestamp (label key `kubernetes.io/legacy-token-last-used`).

### Reuse **FastAPI**'s exception handlers { #reuse-fastapis-exception-handlers }

If you want to use the exception along with the same default exception handlers from  **FastAPI**, you can import and reuse the default exception handlers from `fastapi.exception_handlers`:

     * @param error the error that caused this log
     */

     * The stack trace for this exception will be output when this error level is enabled.

     * @param error the error that caused this log
