I have been using FastAPI for the last two months (which also is an ASGI server and makes full use of annotations and type hints with mypy) and the experience has been incredible. (https://fastapi.tiangolo.com/)

If Django can now also support annotations and async code I dream of an scenario where apis can be built using this two elements.

Does anybody know a good resource to learn/catch up with this release?

See also the base starlette, which is what FastAPI is built upon and is ASGI from the ground up. https://github.com/encode/starlette
