 *  New: `ConnectionSpec.isCompatible(SSLSocket)`.
 *  New: `Dispatcher.getQueuedCallCount()` and
    `Dispatcher.getRunningCallCount()`. These can be useful in diagnostics.
 *  Fix: OkHttp no longer shares timeouts between pooled connections. This was
    causing some applications to crash when connections were reused.
 *  Fix: `OkApacheClient` now allows an empty `PUT` and `POST`.
 *  Fix: Websockets no longer rebuffer socket streams.

   * This test causes two connections to become available simultaneously, one from a TCP connect and
   * one from the pool. We must take the pooled connection because by taking it from the pool, we've

   * This test yields threads to force the decision of plan1 to be deliberate and not lucky. In

    different cipher suite than before! OkHttp's defaults cipher suites are selected for good
    security and performance.

 *  New: `ConnectionListener` publishes events for connects, disconnects, and use of pooled
    connections.

 *  Fix: Immediately update the connection's flow control window instead of waiting for the
    receiving stream to process it.
