> GLPK 4.49 Release Information
> Release date: April 16, 2013

>         The new API routine glp_mincost_relax4, which is a driver to
>         relaxation method of Bertsekas and Tseng (RELAX-IV), was added
>         to the package. RELAX-IV is a code for solving minimum cost
>         flow problems. On large instances it is 100-1000 times faster
>         than the standard primal simplex method. Prof. Bertsekas, the
>         author of the original RELAX-IV Fortran code, kindly permitted
>         to include a C translation of his code in GLPK under GPLv3.

>         Obsolete API routine lpx_check_kkt was replaced by new routine
>         glp_check_kkt.

>         IMPORTANT: All old API routines whose names begin with 'lpx_'
>         were removed from API level and NO MORE AVAILABLE.
