  The computation of microlensing light curves represents a bottleneck for the
modeling of planetary events, making broad searches in the vast parameter space
of microlensing extremely time-consuming. The release of the first version of
VBBinaryLensing (based on the advanced contour integration method presented in
Bozza(2010)) has represented a considerable advance in the field, with the
birth of several analysis platforms running on this code. Here we present the
version 2.0 of VBBinaryLensing, which contains several upgrades with respect to
the first version, including new decision trees that introduce important
optimizations in the calculations.
