+* A modified Biersack-Varelas form which includes an interpolation parameter, `c_i`, that can be used to better match available stopping data for the Bragg peak. 
 * Biersack-Haggmark treatment of high-energy free-flight paths between collisions can be included to greatly speed up high-energy simulations (i.e., by neglecting very small angle scattering).
 * A wide range of interaction potentials are provided, including:
   * the Kr-C, ZBL, Lenz-Jensen, and Moliere universal, screened-Coulomb potentials.

 * Optionally, the code can produce energy-angle and implantation distributions when built with the `--features distributions` flag and disable space-intensive particle list output with `--features no_list_output`.
-* Library functions for modeling ion reflection, implantation, and sputtering in C++/C, Python, and Fortran codes.
