=====================

## Version 4.12.0

_2023-10-16_

 *  Fix: Don't hang taking headers for HTTP 103 responses.

 *  Fix: Recover gracefully when a cache entry's certificate is corrupted.

 *  Fix: Fail permanently when there's a failure loading the bundled public suffix database.
    This is the dataset that powers `HttpUrl.topPrivateDomain()`.

 *  Fix: Immediately update the connection's flow control window instead of waiting for the

    call.execute().use { response ->
      assertThat(response.body.string()).isEqualTo("abc")
      assertThat(response.trailers()).isEqualTo(headersOf("caboose", "xyz"))
    }
  }

  @Disabled("Follow up with fix in https://github.com/square/okhttp/issues/6853")
  @Test
  fun serverDisconnectsBeforeSecondRequestHttp1() {
    enableProtocol(Protocol.HTTP_1_1)

    server.enqueue(MockResponse(code = 200, body = "Req1"))

 * New: Protocol selection in MockWebServer.
 * Fix: Route selection shouldn't use TLS modes that we know will fail.
 * Fix: Cache SPDY responses even if the response body is closed prematurely.
 * Fix: Use strict timeouts when aborting a download.
 * Fix: Support Shoutcast HTTP responses like `ICY 200 OK`.
 * Fix: Don't unzip if there isn't a response body.
 * Fix: Don't leak gzip streams on redirects.
 * Fix: Don't do DNS lookups on invalid hosts.

    ```

 *  Fix: Don't miss cancels when sending HTTP/2 request headers.
 *  Fix: Don't miss whole operation timeouts when calls redirect.
 *  Fix: Don't leak connections if web sockets have malformed responses or if `onOpen()` throws.
 *  Fix: Don't retry when request bodies fail due to `FileNotFoundException`.
 *  Fix: Don't crash when URLs have IPv4-mapped IPv6 addresses.

 *  Fix: Handle response code `308 Permanent Redirect`.
 *  Fix: Don't skip the callback if a call is canceled.
 *  Fix: Permit hostnames with underscores.
 *  Fix: Permit overriding the content-type in `OkApacheClient`.
 *  Fix: Use the socket factory for direct connections.
 *  Fix: Honor `OkUrlFactory` APIs that disable redirects.
 *  Fix: Don't crash on concurrent modification of `SPDY` SPDY settings.

    `NullPointerException: bio == null`.
 *  Fix: Use plus `+` instead of `%20` to encode space characters in `FormBody`. This was a
    longstanding bug in OkHttp. The fix makes OkHttp consistent with major web browsers.
 *  Fix: Don't crash if Conscrypt returns a null version.
 *  Fix: Include the public suffix data as a resource in GraalVM native images.
 *  Fix: Fail fast when the cache is corrupted.
 *  Fix: Fail fast when a private key cannot be encoded.
