To try it out:

* Open the app with several browser tabs.
* Write messages from them.
* Then close one of the tabs.

That will raise the `WebSocketDisconnect` exception, and all the other clients will receive a message like:

 *  Fix: Release the connection if `Authenticator` throws an exception.
 *  Fix: Change the declaration of `OkHttpClient.cache()` to return a `@Nullable Cache`. The return
    value has always been nullable but it wasn't declared properly.
 *  Fix: Reverse suppression of connect exceptions. When both a call and its retry fail, we now
    throw the initial exception which is most likely to be actionable.
