+In this release, we fix several bugs and future deprecation warnings from pandas and numpy.
+In addition, we expand the functionality of some feaure selection classes to return the standard
+deviation of the derived feature importance.
+
+We have also updated and expanded various pages of our documentation.
+
+Thank you very much to all contributors to this release and to `Vasco Schiavo <https://github.com/VascoSch92>`_ and
+`Gleb Levitski <https://github.com/GLevv>`_ for actively discussing many of our PRs and issues.
+
+If you value what we do, consider `sponsoring us <https://github.com/sponsors/solegalli>`_, so that we can keep
+updating Feature-engine at a fast pace.
+
+Enhancements
+~~~~~~~~~~~~
+
+- `ProbeFeatureSelection` can now also determine feature importance through single feature model performance (`Soledad Galli <https://github.com/solegalli>`_)
+- `ProbeFeatureSelection` can now return the standard deviation of the feature importance (`Soledad Galli <https://github.com/solegalli>`_)
+- `RecursiveFeatureElimination` and `RecursiveFeatureAddition` can now return the standard deviation of the feature importances (`Soledad Galli <https://github.com/solegalli>`_)
+- `SelectByShuffling`, `SelectBySingleFeaturePerformance` and `SelectByTargetMeanPerformance` can now return the standard deviation of the feature importances (`Soledad Galli <https://github.com/solegalli>`_)
+- All feature selection classes can now implement Group cross-validation through the `groups` parameter (`Kanan Mahammadli <https://github.com/KananMahammadli>`_)
+
+
+Bug fixes
+~~~~~~~~~
+
+- The cv parameter of the recursive feature selectors can now take cv generators of the type `KFold.split(X, y)` (`Alessandro Benetti <https://github.com/Benetti-Hub>`_)
+- The cv parameter of the remaining feature selection classes can now take cv generators of the type `KFold.split(X, y)` (`Soledad Galli <https://github.com/solegalli>`_)
+- `LogCpTransformer()` adds a constant only to those variables that are strictly non-positive during fit (`Soledad Galli <https://github.com/solegalli>`_)
+- Fix bug in `MatchVariables` that was preventing the transformer to work when missing values were raised (`Soledad Galli <https://github.com/solegalli>`_)
+- Fix bug in `inverse_transform()` from `YeoJohnsonTransformer()` (`Soledad Galli <https://github.com/solegalli>`_)
+- Fix pandas future warnings (`Soledad Galli <https://github.com/solegalli>`_)
+- Fix numpy future warnings (`olikra <https://github.com/olikra>`_)
+
+Code improvements
+~~~~~~~~~~~~~~~~~
+
+- Expand coverage of various tests (`olikra <https://github.com/olikra>`_)
+
+Documentation
+~~~~~~~~~~~~~
+
+- Expand user guide for `ReciprocalTransformer()` (`Sergio Benito Martin <https://github.com/sergiobemar>`_)
+- Expand user guide for `YeoJohnsonTransformer()` (`Ranja Sarkar <https://github.com/ranja-sarkar>`_)
