- Audit events for API requests to deprecated API versions now include a `"k8s.io/deprecated": "true"` audit annotation. If a target removal release is identified, the audit event includes a `"k8s.io/removal-release": "<majorVersion>.<minorVersion>"` audit annotation as well.

使用 `async` 和 `await` 的風格在語言中相對較新。

但它使處理異步程式碼變得更加容易。

相同的語法（或幾乎相同的語法）最近也被包含在現代 JavaScript（無論是瀏覽器還是 NodeJS）中。

但在此之前，處理異步程式碼要更加複雜和困難。

在較舊的 Python 版本中，你可能會使用多執行緒或 <a href="https://www.gevent.org/" class="external-link" target="_blank">Gevent</a>。但這些程式碼要更難以理解、調試和思考。

在較舊的 NodeJS / 瀏覽器 JavaScript 中，你會使用「回呼」，這可能會導致“回呼地獄”。

## 協程

**協程** 只是 `async def` 函式所回傳的非常特殊的事物名稱。Python 知道它是一個類似函式的東西，可以啟動它，並且在某個時刻它會結束，但它也可能在內部暫停 ⏸，只要遇到 `await`。
