Integration with ONNX 1.19.0 #1207
Description
We are in the process of releasing ONNX 1.19.0. The planned release date is late August 2025. A release branch has been created (https://github.com/onnx/onnx/tree/rel-1.19.0). Release candidates are also available from TestPyPI: pip install -i https://test.pypi.org/simple/ --pre onnx
Please take a moment to test the integration of ONNX release branch into sklearn-onnx ASAP so that any issues and incompatibilities can be detected and resolved before the ONNX release. Please open an issue on the ONNX repo for issues encountered.
Up-to-date release info can be found at (https://github.com/onnx/onnx/wiki/Logistics-for-ONNX-Release-1.19.0).
Thank you!
