In this paper we introduce the version 2.5 of Normaliz , a program for the computation of Hilbert bases of rational cones and the normalizations of affine monoids. It may also be used for solving dio-phantine linear systems of inequalities, equations and congruences. We present some of the new features of the program, as well as some recent achievements.
