The treatment of close binary evolution changed from conservative (total mass and angular momentum constant) to non-conservative (a certain fraction of the matter expelled from the mass losing star, the primary, leaves the system, carrying away a fraction of the total angular momentum). Only the evolution of the mass losing star was computed in detail; the evolution of the accreting star was estimated in a very simple way by computing the evolution in the normal way just like for single stars, but taking into account the mass increase.
