+    **DoubleML 0.5.0**
+
+    - Implement a new score function (``'IV-type'``) for the PLIV model (for details see
+      `#161 <https://github.com/DoubleML/doubleml-for-r/pull/161>`_)
+      --> API changed from ``DoubleMLPLIV$new(obj_dml_data, ml_g, ml_m, ml_r [, ...])``
+      to ``DoubleMLPLIV$new(obj_dml_data, ml_g, ml_m, ml_r, ml_g [, ...])``
+    - Adapt the nuisance estimation for the ``'IV-type'`` score for the PLR model (for details see
+      `#161 <https://github.com/DoubleML/doubleml-for-r/pull/161>`_)
+      --> API changed from ``DoubleMLPLR$new(obj_dml_data, ml_g, ml_m [, ...])``
+      to ``DoubleMLPLR$new(obj_dml_data, ml_l, ml_m, ml_g [, ...])``
+    - Use ``task_type`` instead of ``learner_class`` to identify whether a learner is meant to regress or classify (this
+      change makes it possible to easily integrate pipelines from ``mlr3pipelines`` as learner for the nuisance functions)
+      `#141 <https://github.com/DoubleML/doubleml-for-r/pull/141>`_
+    - Add `Contribution Guidelines <https://github.com/DoubleML/doubleml-for-r/blob/master/CONTRIBUTING.md>`_,
