## 進階用法：`scopes` { #advanced-usage-with-scopes }

OAuth2 有「scopes」的概念。

你可以用它們替 JWT 權杖加上一組特定的權限。

接著你可以把這個權杖直接交給某個使用者或第三方，讓他們在一組受限條件下與你的 API 互動。

你可以在之後的「進階使用者指南」學到如何使用它們，以及它們如何整合進 **FastAPI**。

 *  New: `Dispatcher.getQueuedCallCount()` and
    `Dispatcher.getRunningCallCount()`. These can be useful in diagnostics.
 *  Fix: OkHttp no longer shares timeouts between pooled connections. This was
    causing some applications to crash when connections were reused.
 *  Fix: `OkApacheClient` now allows an empty `PUT` and `POST`.
 *  Fix: Websockets no longer rebuffer socket streams.
