## Version 3.5.0

_2016-11-30_

 *  **Web Sockets are now a stable feature of OkHttp.** Since being introduced as a beta feature in
    OkHttp 2.3 our web socket client has matured. Connect to a server's web socket with
    `OkHttpClient.newWebSocket()`, send messages with `send()`, and receive messages with the
    `WebSocketListener`.

    val webSocket: WebSocket = newWebSocket()
    clientListener.assertOpen()
    val server = serverListener.assertOpen()
    webSocket.send("Web Sockets and Events?!")
    serverListener.assertTextMessage("Web Sockets and Events?!")
    webSocket.close(1000, "")
    serverListener.assertClosing(1000, "")
    server.close(1000, "")
    clientListener.assertClosing(1000, "")

 *    be transmitted until the web socket is open.

    HTTP client adapter. (thanks kwuollett)
 *  Work around the Alcatel `getByInetAddress` bug (thanks k.kocel)
 *  Be more aggressive about testing pooled sockets before reuse. (thanks
    warpspin)
 *  Include `Content-Type` and `Content-Encoding` in the Apache HTTP client
    adapter. (thanks kwuollett)
 *  Add a media type class to OkHttp.
 *  Change custom header prefix:

    compressing outbound web socket messages. Configure this with 0L to always compress outbound
    messages and `Long.MAX_VALUE` to never compress outbound messages. The default is 1024L which
    compresses messages of size 1 KiB and larger. (Inbound messages are compressed or not based on
    the web socket server's configuration.)
