Changes:

This release will upgrade to FastAPI 0.74.
This is a minor release to align with FastAPI's versioning strategy.

Note the important breaking change: The internal `AsyncExitStack` was
updated so that dependencies with `yield` can now catch `HTTPException`
and custom exceptions. See the docs for further details:
