Changelog

[4.0.0] - 2024-08-12

  • Enhancement
    • Add support for python 3.11 and 3.10

[3.0.0] - 2023-11-08

  • Enhancement
    • Remove support for python 3.6 and 3.7.
    • Bumps in joblib, numpy, pandas, scikit-learn, statsmodels, toolz, catboost, lightgbm, shap, xgboost and test auxiliary packages.

[2.3.1] - 2023-04-11

  • Bugfix
    • Remove incorrect lightgbm import from common paths

[2.3.0] - 2023-03-28

  • Enhacement
    • Bump maximum allowed scikit-learn
    • Move from CircleCI to Github Actions
    • Add optional weight_column argument for evaluators
    • Change default of min_df from 20 to 1 on TfidfVectorizer
    • Include new optional LGBM parameters to lgbm_classification_learner

[2.2.1] - 2022-09-06

  • Bug Fix
    • Including a necessary init file to allow the import of the causal cate learners.
    • Fix a docstring issue where the description of causal learners were not showing all parameters.

[2.2.0] - 2022-08-25

  • Enhancement
    • Including Classification S-Learner and T-Learner models to the causal cate learning library.
  • Bug Fix
    • Fix validator behavior when receiving data containing gaps and a time based split function that could generate empty training and testing folds and then break. The argument drop_empty_folds can be set to True to drop invalid folds from validation and store them in the log.
  • Documentation
    • Including Classification S-Learner and T-Learner documentation, also changing validator documentation to reflect changes.

[2.1.0] - 2022-07-25

  • Enhancement
    • Add optional parameter return_eval_logs_on_train to the validator function, enabling it to return the evaluation logs for all training folds instead of just the first one
  • Bug Fix
    • Fix import in pd_extractors.py for Python 3.10 compatibility
    • Set a minimal version of Python (3.6.2) for Fklearn
  • Documentation
    • Fixing some typos, broken links and general improvement on the documentation

[2.0.0] - 2021-12-28

  • Possible breaking changes
    • Allow greater versions of catboost, lightgbm, xgboost, shap, swifter (mostly due to deprecation of support to Python 3.5 and older versions). Libraries depending on fklearn can still restrict the versions of the aforementioned libraries, keeping the previous behavior.
