VBBinaryLensing is a public code for the computation of microlensing magnification. It is available in C++ and Python and has been embedded in most microlensing modeling platforms. It is based on contour integration with parabolic corrections and optimal sampling. Current and future missions such as Gaia and Roman will provide more and more detections of astrometric shifts during microlensing events. Such measurements represent important complements to photometry and require simultaneous astrometric and photometric modeling. We present the recent extension of VBBinaryLensing to astrometric microlensing, which comes at practically no additional computational cost with respect to photometry. We also discuss other improvements for limb darkening, orbital motion and the perspectives for an extension to multiple lenses.
