We introduce a new version of SimProp, a Monte Carlo simulation code of ultra-high energy cosmic ray propagation. Compared to the previous versions, SimProp v2r4 adds the possibility of keeping track of the secondary electrons and positrons produced during UHECR propagation. The electromagnetic cascades initiated by these electrons and positrons, as well as by high-energy photons from pion decay, can then in turn be simulated with external codes such as ELMAG. We show a few examples of preliminary physics results to illustrate the capabilities of SimProp v2r4.
