## Version 3.4.1

_2016-07-10_

 *  **Fix a major bug in encoding HTTP headers.** In 3.4.0 and 3.4.0-RC1 OkHttp
    had an off-by-one bug in our HPACK encoder. This bug could have caused the
    wrong headers to be emitted after a sequence of HTTP/2 requests! Everyone
    who is using OkHttp 3.4.0 or 3.4.0-RC1 should upgrade for this bug fix.

 * segments `["a", "b"]` build "/a/b" and the segments `["a", "b", ""]` build "/a/b/".
 *
 * If a path's last segment is the empty string then the path ends with "/". This class always
 * builds non-empty paths: if the path is omitted it defaults to "/". The default path's segment
 * list is a single empty string: `[""]`.
 *
 * ### Query
 *
 * The query is optional: it can be null, empty, or non-empty. For many HTTP URLs the query string

    // Note that although we have two routes available, we only use one. The retry is permitted
    // because there are routes available, but it chooses the existing connection since it isn't
    // yet considered unhealthy.

    //  * URI is much more strict than HttpUrl or URL on what's accepted.
    //
    // HttpUrl is quite lenient with what characters it accepts. In particular, characters like '{'
    // and '"' are permitted but unlikely to occur in real-world URLs. Unfortunately we can't just
    // lock it down due to URL templating: "http://{env}.{dc}.example.com".
