Style has been improved to enhance the curve quality of single natural tangency curves without internal knots.

Previously two-point curves without internal knots had distortion. Without internal knots, there was inflection in the curve’s free end when the other end's tangency was defined.

In 11, the algorithm of natural tangency calculation for a curve with only two interpolation points and a single tangency was improved, to result in a more natural curve with no inflection.
