Curently only SelectorMixin-based transformers, FeatureUnion and transformers with get_feature_names are supported, but users can register other transformers; built-in list of supported transformers will be expanded in future. See :ref:`sklearn-pipelines` for more.
• Inverting of HashingVectorizer is now supported inside FeatureUnion via :func:`eli5.sklearn.unhashing.invert_hashing_and_fit`. See :ref:`sklearn-unhashing`.

0.4.1 (2017-01-25)

• feature contribution calculation fixed for :func:`eli5.xgboost.explain_prediction_xgboost`

0.4 (2017-01-20)
