OkHttp 4.x Change Log
=====================

## 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: Don't leak file handles when a cache disk write fails.

 *  Fix: Don't hang when the public suffix database cannot be loaded. We had a bug where a failure
    reading the public suffix database would cause subsequent reads to hang when they should have
    crashed.

 *  Fix: Avoid `InetAddress.getCanonicalHostName()` in MockWebServer. This avoids problems if the

    assertThat(other.port).isNotEqualTo(server.port)
    other.shutdown()
  }
