    This applies to `Authorization`, `Cookie`, `Proxy-Authorization`, and `Set-Cookie` headers.
 *  Fix: Don't crash with an `InaccessibleObjectException` when running on JDK17+ with strong
    encapsulation enabled.
 *  Fix: Strictly verify hostnames used with OkHttp's `HostnameVerifier`. Programs that make direct
    manual calls to `HostnameVerifier` could be defeated if the hostnames they pass in are not

# 並行処理と async / await

*path operation 関数*のための `async def` に関する詳細と非同期 (asynchronous) コード、並行処理 (Concurrency)、そして、並列処理 (Parallelism) の背景について。

## 急いでいますか？

<abbr title="too long; didn't read (長すぎて読めない人のための要約という意味のスラング)"><strong>TL;DR:</strong></abbr>

次のような、`await` を使用して呼び出すべきサードパーティライブラリを使用している場合:

```Python
results = await some_library()
```

以下の様に `async def` を使用して*path operation 関数*を宣言します。

```Python hl_lines="2"

I shall never get to twenty at that rate!  However, the
Multiplication Table doesn't signify:  let's try Geography.
London is the capital of Paris, and Paris is the capital of Rome,
and Rome--no, THAT'S all wrong, I'm certain!  I must have been
changed for Mabel!  I'll try and say "How doth the little--"'

 *  Fix: Don't leak connections when using ALPN on the desktop.
 *  Fix: Update Jetty ALPN to `7.1.2.v20141202` (Java 7) and `8.1.2.v20141202` (Java 8).
    This fixes a bug in resumed TLS sessions where the wrong protocol could be
    selected.
 *  Fix: Don't crash in SPDY and HTTP/2 when disconnecting before connecting.
 *  Fix: Avoid a reverse DNS-lookup for a numeric proxy address
 *  Fix: Resurrect http/2 frame logging.
