+**New Features**

+* Carriers of generators can now be excluded from aggregation in clustering network and simplify network.
+
+**Breaking Changes**
+
+* The config entry ``snapshots["closed"]`` was renamed to ``snapshots["inclusive"]`` to address the upstream deprecation with ``pandas=1.4``.
+  The previous setting ``None`` is no longer supported and replaced by ``both``, see the `pandas documentation <https://pandas.pydata.org/docs/reference/api/pandas.date_range.html>`_.
+  Minimum ``pandas`` version now required is `>= 1.4`.
