## Version 4.9.3

_2021-11-21_

 *  Fix: Don't fail HTTP/2 responses if they complete before a `RST_STREAM` is sent.


## Version 4.9.2

_2021-09-30_

 *  Fix: Don't include potentially-sensitive header values in `Headers.toString()` or exceptions.
    This applies to `Authorization`, `Cookie`, `Proxy-Authorization`, and `Set-Cookie` headers.

## 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`.


## Version 3.4.0-RC1

_2016-07-02_

 *  **We’ve rewritten HttpURLConnection and HttpsURLConnection.** Previously we

 *  Fix: `OkApacheClient` now allows an empty `PUT` and `POST`.
 *  Fix: Websockets no longer rebuffer socket streams.
 *  Fix: Websockets are now better at handling close frames.
 *  Fix: Content type matching is now case insensitive.
 *  Fix: `Vary` headers are not lost with `android.net.http.HttpResponseCache`.
 *  Fix: HTTP/2 wasn't enforcing stream timeouts when writing the underlying
    connection. Now it is.
