|

|

- The ``Exception`` subclasses have been moved to an ``.exceptions`` module
|

within each package (for example, ``qiskit.exceptions.QiskitError``). (#1600).
|

- The ``QiskitTestCase`` and testing utilities are now included as part of
|

``qiskit.test`` and thus available for third-party implementations. (#1616).
