Recent enhancements and additions to the SASfit program are discussed, including anisotropic scattering models, flexible distributions, regularization techniques such as the expectation-maximization method, and new structure factors, especially for ordered nano- and meso-scaled material. The Ornstein–Zernike solver for numerical structure factors is also introduced.
