This release fixes compatibility issues with the latest versions of scikit-learn. The main reason for this upgrade are security concerns (see issue #141). The following features had to be removed as it was not possible to make them compatible with scikit-learn v1.5+:
- Multi-label local hierarchical classifiers
- Bert classifier
- Explainer class
Perhaps in future releases these features will be reintegrated, but for now they are only available until hiclass v4.
