Fixed bug in art.utils.load_nursery for loading nursery dataset with argument raw=True. (#1460)
Fixed import of matplotlib to keep it an optional dependency. (#1467)
Fixed bug to allow preprocessing defences to be applied in PyTorchGoturn.predict by adding back missing sample dimension. (#1470)
Fixed bug in PyTorchClassifier.get_activations to also apply preprocessing if argument framework=True. This fix likely changes the results obtained with BullseyePolytopeAttackPyTorch, the main attack using framework=True. (#1471)
