You can use `async` or regular functions.

**FastAPI** will do the right thing with each, the same as with normal dependencies.

The rest of this release is our highest-quality release yet. Though we continue to use the word
_alpha_ in the version name, the only unstable thing in it is some non-final APIs tagged
`@ExperimentalOkHttpApi`. You can safely use this release in production.

 *  Fix: Attempt to read the response even if sending the request failed. This makes it possible
