In order to bump starlette version, FastAPI has to drop support for Python 3.6.

Currently FastAPI supports python 3.6.

Currently FastAPI supports python 3.6.

When do you expect to drop support for python 3.6?
It is said that "This is probably the last release (or one of the last releases) to support Python 3.6." in the latest release notes.

It's up to the maintainers of the project. I don't have an answer for when it'd be done🙂

• Duplicated Bump starlette to 0.20.4 #5172

Also, tiangolo bumps Starlette's version individually, so from 0.19.1 to 0.20.4 there are some steps 😅

I use route paths with colons, so I am pinned to fastapi<0.76.0 for now. I'm glad https://fastapi.tiangolo.com/release-notes/#0820 announced intent of dropping Python 3.6 support.

[SogoKato]

Now https://github.com/tiangolo/fastapi/releases/tag/0.85.0 is released, I close this p-r.

Thanks for coming back to close the PR @SogoKato ! ☕
