*  Fix: Don't share the OkHttpClient's `Dispatcher` in `HttpURLConnection`.


## Version 3.4.0-RC1

_2016-07-02_

 *  **We’ve rewritten HttpURLConnection and HttpsURLConnection.** Previously we
    shared a single HTTP engine between two frontend APIs: `HttpURLConnection`
    and `Call`. With this release we’ve rearranged things so that the
    `HttpURLConnection` frontend now delegates to the `Call` APIs internally.

    add the `okhttp-urlconnection` module to your project and use the
    `OkUrlFactory` to create new instances of `HttpURLConnection`:

    ```java
    // OkHttp 1.x:
    HttpURLConnection connection = client.open(url);

    // OkHttp 2.x:
    HttpURLConnection connection = new OkUrlFactory(client).open(url);
    ```

 *  **Custom caches are no longer supported.** In OkHttp 1.x it was possible to

 * Fix: Connection reuse was broken for most HTTPS connections due to a bug in
   the way the hostname verifier was selected.
 * Fix: Locking bug in SpdyConnection.
 * Fix: Ignore null header values (for compatibility with HttpURLConnection).
 * Add URLStreamHandlerFactory support so that `URL.openConnection()` uses
   OkHttp.
 * Expose the transport ("http/1.1", "spdy/3", etc.) via magic request headers.

Concurrency
===========

This document describes the concurrency considerations for http/2 connections and the connection pool within OkHttp.

## HTTP/2 Connections

The HttpURLConnection API is a blocking API. You make a blocking write to send a request, and a blocking read to receive the response.

#### Blocking APIs

   * Writes are subject to the write window of the stream and the connection. Until there is a
   * window sufficient to send [byteCount], the caller will block. For example, a user of
   * `HttpURLConnection` who flushes more bytes to the output stream than the connection's write
   * window will block.
   *
   * Zero [byteCount] writes are not subject to flow control and will not block. The only use case
