Release Notes
=============

scikit-survival 0.17.0 (2022-01-09)
-----------------------------------

This release adds support for scikit-learn 1.0, which includes
support for feature names.
If you pass a pandas dataframe to ``fit``, the estimator will
set a `feature_names_in_` attribute containing the feature names.
When a dataframe is passed to ``predict``, it is checked that the
column names are consistent with those passed to ``fit``. See the
`scikit-learn release highlights <https://scikit-learn.org/stable/auto_examples/release_highlights/plot_release_highlights_1_0_0.html#feature-names-support>`_
for details.

Bug fixes
^^^^^^^^^
- Fix a variety of build problems with LLVM (:issue:`243`).

Enhancements
^^^^^^^^^^^^
- Add support for ``feature_names_in_`` and ``n_features_in_``
to all estimators and transforms.
- Add :meth:`sksurv.preprocessing.OneHotEncoder.get_feature_names_out`.
- Update bundeled version of Eigen to 3.3.9.

Backwards incompatible changes
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
- Drop ``min_impurity_split`` parameter from
:class:`sksurv.ensemble.GradientBoostingSurvivalAnalysis`.
- ``base_estimators`` and ``meta_estimator`` attributes of
:class:`sksurv.meta.Stacking` do not contain fitted models anymore,
use ``estimators_`` and ``final_estimator_``, respectively.

Deprecations
^^^^^^^^^^^^
- The ``normalize`` parameter of :class:`sksurv.linear_model.IPCRidge`
is deprecated and will be removed in a future version. Instead, use
a sciki-learn pipeline:
``make_pipeline(StandardScaler(with_mean=False), IPCRidge())``.
