+-------------
+*April 14, 2021*
+
+- Add :class:`~sklearn_extra.robust.RobustWeightedClassifier`,
+  :class:`~sklearn_extra.robust.RobustWeightedRegressor` and
+  :class:`~sklearn_extra.robust.RobustWeightedKMeans` estimators that rely on
+  iterative reweighting of samples to be robust to
+  outliers. [`#42 <https://github.com/scikit-learn-contrib/scikit-learn-extra/pull/42>`_].
+- Added Common Nearest-Neighbors clustering estimator
+  :class:`~sklearn_extra.cluster.CommonNNClustering`
+  [`#64 <https://github.com/scikit-learn-contrib/scikit-learn-extra/pull/64>`_]
+- Added PAM algorithm to :class:`~sklearn_extra.cluster.KMedoids` with ``method="pam"`` parameter
+  which produces better solutions but at higher computational cost
+  [`#73 <https://github.com/scikit-learn-contrib/scikit-learn-extra/pull/73>`_]
+- Binary wheels were uploaded to PyPi, making the installation possible without a C compiler
+  [`#66 <https://github.com/scikit-learn-contrib/scikit-learn-extra/pull/66>`_]
