 *  Fix: Don’t use the request's `User-Agent` or `Proxy-Authorization` when
    connecting to an HTTPS server via an HTTP tunnel. The `Proxy-Authorization`
    header was being leaked to the origin server.
 *  Fix: Digits may be used in a URL scheme.
 *  Fix: Improve connection timeout recovery.

### 自動 API ドキュメントの確認 { #check-the-automatic-api-docs }

では、`fastapi` コマンドを実行します:

<div class="termy">

```console
$ fastapi dev

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)

    platform-specific TLS features OkHttp must detect whether it's running in a JVM or in Android.
    The upcoming Android Studio runs in a JVM but has classes from Android and that confused OkHttp!
