## Version 3.14.1

_2019-04-10_

 *  Fix: Don't crash when an interceptor retries when there are no more routes. This was an
    edge-case regression introduced with the events cleanup in 3.14.0.

 *  Fix: Provide actionable advice when the exchange is non-null. Prior to 3.14, OkHttp would
    silently leak connections when an interceptor retries without closing the response body. With

     *
     * The call timeout spans the entire call: resolving DNS, connecting, writing the request body,
     * server processing, and reading the response body. If the call requires redirects or retries
     * all must complete within one timeout period.
     *
     * The default value is 0 which imposes no timeout.

    @Test

 * string `cute #puppies` is encoded as `cute%20%23puppies` when used as a query parameter value.
 *
 * ### Percent encoding
 *
 * Percent encoding replaces a character (like `\ud83c\udf69`) with its UTF-8 hex bytes (like
 * `%F0%9F%8D%A9`). This approach works for whitespace characters, control characters, non-ASCII
