In the last year, there were a lot of innovations in the ASGI specification. A lot of extensions were introduced, the wording on the specification itself was clarified, and some new things were included.
In this talk, we're going to see the changes that were brought from the ASGI specification to Uvicorn, and Starlette, and how FastAPI benefits from them.
