 - The Modified Akima Interpolation has been added to
   ``interpolate.Akima1DInterpolator``, available via the new ``method``
   argument.
-- New method ``BSpline.insert_knot`` inserts a knot into a ``BSpline` instance.
+- New method ``BSpline.insert_knot`` inserts a knot into a ``BSpline`` instance.
   This routine is similar to the module-level `scipy.interpolate.insert`
   function, and works with the BSpline objects instead of ``tck`` tuples.
 - ``RegularGridInterpolator`` gained the functionality to compute derivatives
