 *  New: Prefer the client's configured precedence order for TLS cipher suites. (OkHttp used to
    prefer the JDK’s precedence order.) This change may cause your HTTP calls to negotiate a
    different cipher suite than before! OkHttp's defaults cipher suites are selected for good
    security and performance.
