+.. _whatsnew_100.numba_rolling_apply:
+
+Using Numba in ``rolling.apply`` and ``expanding.apply``
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+We've added an ``engine`` keyword to :meth:`~core.window.rolling.Rolling.apply` and :meth:`~core.window.expanding.Expanding.apply`
+that allows the user to execute the routine using `Numba <https://numba.pydata.org/>`__ instead of Cython.
+Using the Numba engine can yield significant performance gains if the apply function can operate on numpy arrays and
+the data set is larger (1 million rows or greater). For more details, see
+:ref:`rolling apply documentation <stats.rolling_apply>` (:issue:`28987`, :issue:`30936`)
+
+.. _whatsnew_100.custom_window:
+
+Defining custom windows for rolling operations
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+We've added a :func:`pandas.api.indexers.BaseIndexer` class that allows users to define how
+window bounds are created during ``rolling`` operations. Users can define their own ``get_window_bounds``
+method on a :func:`pandas.api.indexers.BaseIndexer` subclass that will generate the start and end
+indices used for each window during the rolling aggregation. For more details and example usage, see
+the :ref:`custom window rolling documentation <stats.custom_rolling_window>`

+.. _whatsnew_100.to_markdown:
