GLPK 4.19 -- Release Information
********************************

Release date: Jul 05, 2007

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 principal change is upgrading to GPLv3.

*  A serious bug in the routine glp_del_cols was fixed. Thanks to
   Cedric[FR] <address@hidden> for the bug report.

*  A new advanced API routine glp_mem_limit was added.

*  The case GLP_EBOUND was added to the routine lpx_simplex. Thanks to
   Cameron Kellough <address@hidden> for the bug report.

*  An API routine lpx_write_pb to write the problem instance in OPB
   (pseudo boolean) format format was added. Thanks to Oscar Gustafsson
   <address@hidden> for the contribution.

*  Two new options --wpb and --wnpb were added to glpsol to write the
   problem instance in OPB format.
