    `OkHttpClient.newWebSocket()`, send messages with `send()`, and receive messages with the
    `WebSocketListener`.

    The `okhttp-ws` submodule is no longer available and `okhttp-ws` artifacts from previous
    releases of OkHttp are not compatible with OkHttp 3.5. When upgrading to the new package

 *  **RC4 cipher suites are no longer supported by default.** To connect to
    old, obsolete servers relying on these cipher suites, you must create a
    custom `ConnectionSpec`.

 *  **Beta WebSockets support.**. The `okhttp-ws` subproject offers a new
    websockets client. Please try it out! When it's ready we intend to include
    it with the core OkHttp library.

 *  **Okio updated to 1.3.0.**
