GLPK 4.6 -- Release Information
===============================

Release date: Aug 04, 2004

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 in the form of a callable library.

In 4.6:

Three new statements were implemented in the GNU MathProg language:
solve, printf, and for. Their detailed description can be found in the
GLPK documentation included in the distribution. (See also a sample
model, examples/queens.mod, which illustrates using these statements.)

Two new API routines were added to the package: lpx_read_prob and
lpx_write_prob. They allow reading/writing problem data in GNU LP text
format.

Three new command-line options were implemented in the LP/MIP solver
glpsol: --glp (to read problem data in GNU LP format), --wglp (to write
problem data in GNU LP format), and --name (to change problem name).
Now glpsol also supports processing models where the new statements
(mentioned above) are used.

A new version of GLPKMEX, a Matlab MEX interface to GLPK, was included.
For more details see contrib/glpkmex/ChangeLog.
