GLPK 4.59.2 Release Information
*******************************

Release date: March 18, 2016

        THIS IS A NON-OFFICIAL TEST RELEASE.

        Some improvements were made in the primal and dual simplex
        solvers to make the solution process more numerically stable.

        An experimental long-step ratio test feature was added to the
        dual simplex. On API level this feature is available thru the
        GLP_RT_FLIP option. For glpsol it is available thru the options
        --flip (for MIP) or --flip and --dual (for LP). This feature is
        not documented yet.

        Additional check was added to reject wrong solutions sometimes
        reported by the PROXY heuristic.

        A bug (memory leak) was fixed in the FPUMP heuristic routine.
        Thanks to <address@hidden> for bug report.

The GLPK tarball can be downloaded from alpha.gnu.org/gnu/glpk via ftp
or http.

MD5 check-sum is the following:
