+Metadata Routing
+----------------
+
+The following models now support metadata routing in one or more or their
+methods. Refer to the :ref:`Metadata Routing User Guide <metadata_routing>` for
+more details.
+
+- |Enhancement| :class:`~compose.ColumnTransformer` now supports metadata routing
+  according to :ref:`metadata routing user guide <metadata_routing>`. :pr:`27005`
+  by `Adrin Jalali`_.
+
+- |Enhancement| :class:`linear_model.LogisticRegressionCV` now supports
+  metadata routing. :meth:`linear_model.LogisticRegressionCV.fit` now
+  accepts ``**params`` which are passed to the underlying splitter and
+  scorer. :meth:`linear_model.LogisticRegressionCV.score` now accepts
+  ``**score_params`` which are passed to the underlying scorer.
+  :pr:`26525` by :user:`Omar Salman <OmarManzoor>`.
+
+- |Feature| :class:`pipeline.Pipeline` now supports metadata routing according
+  to :ref:`metadata routing user guide <metadata_routing>`. :pr:`26789` by
+  `Adrin Jalali`_.
+
+- |Feature| :func:`~model_selection.cross_validate`,
+  :func:`~model_selection.cross_val_score`, and
+  :func:`~model_selection.cross_val_predict` now support metadata routing. The
+  metadata are routed to the estimator's `fit`, the scorer, and the CV
+  splitter's `split`. The metadata is accepted via the new `params` parameter.
+  `fit_params` is deprecated and will be removed in version 1.6. `groups`
+  parameter is also not accepted as a separate argument when metadata routing
+  is enabled and should be passed via the `params` parameter. :pr:`26896` by
+  `Adrin Jalali`_.
+
+- |Feature| :class:`~model_selection.GridSearchCV`,
+  :class:`~model_selection.RandomizedSearchCV`,
+  :class:`~model_selection.HalvingGridSearchCV`, and
+  :class:`~model_selection.HalvingRandomSearchCV` now support metadata routing
+  in their ``fit`` and ``score``, and route metadata to the underlying
+  estimator's ``fit``, the CV splitter, and the scorer. :pr:`27058` by `Adrin
