## Version 4.9.3

 *  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.
 *  Fix: Don't crash with an `InaccessibleObjectException` when running on JDK17+ with strong

 * it easy to get sample values to use in such tests.
 *
 * This class is pretty fast and loose with default values: it attempts to provide values that are
 * well-formed, but doesn't guarantee values are internally consistent. Callers must take care to
 * configure the factory when sample values impact the correctness of the test.
