  The Sky3D code has been widely used to describe nuclear ground states,
collective vibrational excitations, and heavy-ion collisions. The approach is
based on Skyrme forces or related energy density functionals. The static and
dynamic equations are solved on a three-dimensional grid, and pairing is been
implemented in the BCS approximation. This updated version of the code aims to
facilitate the calculation of nuclear strength functions in the regime of
linear response theory, while retaining all existing functionality and use
cases. The strength functions are benchmarked against available RPA codes, and
the user has the freedom of choice when selecting the nature of external
excitation (from monopole to hexadecapole and more). Some utility programs are
also provided that calculate the strength function from the time-dependent
output of the dynamic calculations of the Sky3D code.
