GLPK 3.0 -- Release Information
*******************************

Release date: Jul 19, 2001

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.

Now GLPK is provided with new API, which allows using the package in
more complex algorithmic schemes. In particular: a) arbitrary number
of LP/MIP problem instances are allowed; b) rows and columns are now
referenced by their sequential numbers, not by symbolic names, although
symbolic names also can be used; c) any problem object can be created,
modified, or deleted dynamically.

New edition of the document "GLPK User's Guide", which describes the
new version of GLPK API, is included in the distribution (see the file
INSTALL to consult about making documentation).

Old GLPK API routines are not removed yet from the package, however they
became obsolete and therefore should not be used.

So far as the header 'glpk.h' now corresponds to the new API, in order
to compile existing programs that use old API the statement

#define GLP_OLD_API

should be inserted before the statement

#include "glpk.h"

Please note that the current version of GLPK is *tentative*.
