  DPMJET is a Monte Carlo model for sampling of hadron-hadron, hadron-nucleus,
nucleus-nucleus and neutrino-nucleus interactions at accelerator and Cosmic Ray
energies according to the two-component Dual Parton Model. Here we describe new
features in version DPMJET-II.5: Implementation of new DPM diagrams for an
improved description of baryon stopping in nuclear collisions and improvements
in the calculation of Glauber cross sections. The new diagrams allow two quite
different extrapolations of the model to the highest Cosmic Ray energies. The
new version of the model is compared to experimental data on hadron-hadron,
hadron-nucleus and nucleus-nucleus collisions.
