a source-incompatible change, and is different from OkHttp 2.0.0-RC2 which
    used `Throwable`.
 *  Fix: Fixed a caching bug where we weren't storing rewritten request headers
    like `Accept-Encoding`.
 *  Fix: Fixed bugs in handling the SPDY window size. This was stalling certain
    large downloads
 *  Update the language level to Java 7. (OkHttp requires Android 2.3+ or Java 7+.)

## Version 2.0.0-RC2

class Cat:
    def __init__(self, name: str):
        self.name = name


fluffy = Cat(name="Mr Fluffy")
```

In this case, `fluffy` is an instance of the class `Cat`.

And to create `fluffy`, you are "calling" `Cat`.

So, a Python class is also a **callable**.

Then, in **FastAPI**, you could use a Python class as a dependency.

 * an open file (for cached responses). Failing to close the response body will leak resources and
 * may ultimately cause the application to slow down or crash.
 *
 * Both this class and [Response] implement [Closeable]. Closing a response simply
 * closes its response body. If you invoke [Call.execute] or implement [Callback.onResponse] you
 * must close this body by calling any of the following methods:
 *
 * * `Response.close()`
