Support change

• Support for Python 3.8 has been dropped.

Bug fix

• Value propagation of string tensors no longer raises an erroneous ValueError in some instances.

Deprecation

• Importing spox._future.operator_overloading now triggers a DeprecationWarning. The function will be removed in a future release. Consider using ndonnx as an alternative.
