GLPK 4.53 Release Information
*****************************

Release date: February 13, 2014

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 C89 and
organized as a callable library.

        In this release:

        The API routine glp_read_mps was changed to remove free rows.

        A bug was fixed in the API routine glp_read_lp. Thanks to
        Gabriel Hackebeil <address@hidden> for bug report.

        The zlib compression library used by some GLPK routines and
        included in the package was downgraded from 1.2.7 to 1.2.5 (as
        in GLPK 4.50) because of addressability bugs on some 64-bit
        platforms. Thanks to Carlo Baldassi <address@hidden>
        for bug report.

        A bug was fixed in a routine that reads gzipped files. Thanks
        to Achim Gaedke <address@hidden> for bug report.

        Two API routines glp_get_it_cnt and glp_set_it_cnt were added.
        Thanks to Joey Rios <address@hidden> for suggestion.

        All obsolete GLPK API routines (prefixed with lpx) were removed
        from the package.

        A set of routines that simulate the old GLPK API (as defined in
        GLPK 4.48) was added; for details see examples/oldapi/README.
        Thanks to Jan Engelhardt <address@hidden> for suggestion.

        A namespace bug was fixed in the SQL table driver. Thanks to
        Dennis Schridde <address@hidden> for bug report.
