| Fixed a bug where deserialized objects with ``cache_hash=True`` could have incorrect hash code values. | |
| This change breaks classes with ``cache_hash=True`` when a custom ``__setstate__`` is present. | |
| An exception will be thrown when applying the ``attrs`` annotation to such a class. | |
| This limitation is tracked in issue `#494 <https://github.com/python-attrs/attrs/issues/494>`_. |
