GLPK 4.32 -- Release Information
********************************

Release date: Oct 03, 2008

GLPK (GNU Linear Programming Kit) is intended for solving large-scale
linear programming (LP), mixed integer linear programming (MIP), and
other related problems. It is a set of routines written in ANSI C and
organized as a callable library.

In this release:

        The following new features were included in the MIP solver
        (the API routine glp_intopt):

        *  MIP presolver
        *  mixed cover cut generator
        *  clique cut generator
        *  Euclidean reduction of the objective value

        Due to changes the routine glp_intopt may additionally return
        GLP_ENOPFS, GLP_ENODFS, and GLP_EMIPGAP.

        The API routines lpx_integer are lpx_intopt are deprecated,
        since they are completely superseded by glp_intopt.

        The following new branch-and-cut API routines were added:
        glp_ios_row_attr      determine additional row attributes
        glp_ios_pool_size     determine current size of the cut pool
        glp_ios_add_row       add constraint to the cut pool
        glp_ios_del_row       delete constraint from the cut pool
        glp_ios_clear_pool    delete all constraints from the cut pool

        For description of these new routines see the reference manual
        included in the distribution.

        The stand-alone solver glpsol was changed to allow multiple
        data files.

        A new edition of the supplement "Using Data Tables in the GNU
        MathProg Modeling Language" was included.

        As usual, some bugs were fixed (in the MathProg translator).
