    who is using OkHttp 3.4.0 or 3.4.0-RC1 should upgrade for this bug fix.


## Version 3.4.0

_2016-07-08_

 *  New: Support dynamic table size changes to HPACK Encoder.
 *  Fix: Use `TreeMap` in `Headers.toMultimap()`. This makes string lookups on
    the returned map case-insensitive.
 *  Fix: Don't share the OkHttpClient's `Dispatcher` in `HttpURLConnection`.
