 Breaking changes
 ~~~~~~~~~~~~~~~~
-
+- Methods including ``dropna``, ``rank``, ``idxmax``, ``idxmin`` require
+  non-dimension arguments to be passed as keyword arguments. The previous
+  behavior, which allowed ``.idxmax('foo', 'all')`` was too easily confused with
+  ``'all'`` being a dimension. The updated equivalent is ``.idxmax('foo',
+  how='all')``. The previous behavior was deprecated in v2023.10.0.
