GLPK 4.41 -- Release Information
********************************

Release date: Dec 21, 2009

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 API routines were added:

        glp_transform_row     transform explicitly specified row
        glp_transform_col     transform explicitly specified column
        glp_prim_rtest        perform primal ratio test
        glp_dual_rtest        perform dual ratio test

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

        The following API routines are deprecated: lpx_transform_row,
        lpx_transform_col, lpx_prim_ratio_test, lpx_dual_ratio_test.

        Some improvements were made in the MIP solver (glp_intopt).

        The SQL table driver used to read/write data in MathProg models
        was changed to allow multiple arguments separated by semicolon
        in SQL statements. Thanks to Xypron <address@hidden>.

        Two new options were added to the glpsol stand-alone solver:
        --seed value (to initialize the pseudo-random number generator
        used in MathProg models with specified value), and
        --ini filename (to use a basis previously saved with -w option
        as an initial basis on solving similar LP's).

        Two new MathProg example models were included. Thanks to
        Nigel Galloway <address@hidden> and Noli Sicad
        <address@hidden> for contribution.

        Scripts to build GLPK with Microsoft Visual Studio 2010 for
        both 32-bit and 64-bit Windows were included. Thanks to Xypron
        <address@hidden> for contribution and testing.
