   :func:`iris.experimental.concatenate.concatenate` function raised an

+* The :func:`iris.analysis.maths.apply_ufunc` keyword argument has changed
+  from ``other_cube`` to ``other``, which aligns it with the rest of the
+  :mod:`iris.analysis.maths` API.

+* The :meth:`iris.analysis.maths.IFunc.__call__` now ignores any surplus ``other``
+  keyword argument provided for a ``data_func`` that only requires **one** argument.
+  This aligns the behaviour of :meth:`iris.analysis.maths.IFunc.__call__` with
+  :func:`~iris.analysis.maths.apply_ufunc`. Previously a ``ValueError`` exception
