 * ``qml.circuit_drawer.CircuitDrawer`` can accept a string for the ``charset`` keyword, instead of a ``CharSet`` object.
   [(#1640)](https://github.com/PennyLaneAI/pennylane/pull/1640)
 
+* ``qml.math.sort`` will now return only the sorted torch tensor and not the corresponding indices, making sort consistent across interfaces.

 * Operations can now have gradient recipes that depend on the state of the operation.
