• Fixed GitHub Actions, check and test issues (#25, #29)
• Fixed issues with documentation and examples
• Changed use of bitwise '|' to logical '||' with boolean operands in C++ files

treeshap 0.1.1

• Fixed plot_contribution when max_vars is larger than the number of variables (#16)

treeshap 0.1.0

• Rebuilded all unifiers so they require passing data.

treeshap 0.0.1

• Made package pass all checks
• Fixed infinite recursion issue in ranger (see commit)
• If there is no missing value in the model, unifiers return NA for Missing column (see commit)

treeshap 0.0.0.9000

• treeshap is now public
• Implemented fast computations of tree ensemble shap values in C++
• Implemented unifiers for catboost, lightgbm, xgboost, gbm, ranger and randomForest
