    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.
