- Update to version 5.0
* The copyright was transferred to the Free Software Foundation.
* To fix some licensing problems the routines in the following
files were disabled by replacing with dummy ones that print an
error message:
+ src/api/gridgen.c
+ src/api/netgen.c
+ src/api/rmfgen.c
+ src/misc/qmd.c
+ src/misc/relax4.c
+ Note that this change does not affect the main functionality
of the package.
* Some minor bugs were fixed.

function.

* Wed Jun 27 2018 mpluskal@suse.com
- Update to version 4.65:
* The following new API routines for LP/MIP preprocessing were added:
+ glp_npp_alloc_wksp allocate the preprocessor workspace
+ glp_npp_load_prob load original problem instance
+ glp_npp_preprocess1 perform basic LP/MIP preprocessing
+ glp_npp_build_prob build resultant problem instance
+ glp_npp_postprocess postprocess solution to resultant problem
+ glp_npp_obtain_sol obtain solution to original problem
+ glp_npp_free_wksp free the preprocessor workspace
* A new, more robust implementation of locally valid simple cover
cuts was included in the MIP solver.
* The API routine glp_init_iocp was changed to enable long-step
option of the dual simplex by default.
- Add glpk-no_random_return.patch
* Mon Dec 11 2017 astieger@suse.com
- update to 4.64:
* The dual simplex solver routine was changed to perform more
aggressive perturbation to prevent dual degeneracy and avoid
stalling even if the current dual basic solution is strongly
feasible (mainly if the objective is zero)
* The exact simplex solver routine was changed to perform
terminal output according to the verbosity level (specified by
the control parameter smcp.msg_lev)
* A minor bug (related to MS Windows version) was fixed
* An example model (Graceful Tree Labeling Problem) in MathProg
was added
* Three example models (Power plant LP scheduler, Neumann CA
grid emulator generator) in MathProg and one in Cplex LP format
were added
* Mon Jul 31 2017 mpluskal@suse.com
- Update to version 4.63:
* A "smart" LP perturbation was implemented in the primal and
dual simplex solvers.
* The long-step technique was implemented for phase I of the
primal simplex solver.
* An internal objective scaling was included in both primal and
ual simplex solvers.
* The Posix version of glp_time (glpk/src/env/time.c) was changed
to resolve time_t issue on msys2.
* Three new example models in MathProg were added.
* Changes for version 4.62:
* The bound perturbation technique was included in the primal
simplex solver to improve numerical stability and avoid
cycling.
* A range bug was fixed in the MPS reading routine.
* Changes were made to provide 64-bit portability of the Minisat
solver.
* Calls to non-thread-safe functions gmtime, strerror, and strtok
were replaced by calls to corresponding thread-safe equivalents
* Mon Jan 23 2017 mpluskal@suse.com
- Update to version 4.61:
* An option was added to build a re-entrant version of the
package suitable for running in a multi-threaded environment.
* A re-entrant version of the package allows running multiple
independent instances of glpk in different threads of a
multi-threaded application.
- Use savannah as source for gpg keyring
* Fri Apr 01 2016 mpluskal@suse.com
- Update to 4.60
* src/glpk.h Declarations of all non-documented API routines were
hidden by #ifdef GLP_UNDOC / #endif.
* src/simplex/spydual.c An experimental feature (objective
coefficient perturbation) to improve numerical stabilty and
avoid cycling was included in the dual simplex solver.
- Enable gmp support
* Sun Mar 13 2016 mpluskal@suse.com
- Update to 4.59
* Some bugs were fixed and some improvements were made in the
MIP solver.
* The data file format used by API routines glp_read_graph and
glp_write_graph was changed. For more details please see the
document "GLPK: Graph and Network Routines" included in the
distribution.
* Translation of the document "Modeling Language GNU MathProg"
to Brazilian Portuguese (pt-BR) was included (in LaTeX and pdf
formats).
* Fri Feb 19 2016 mpluskal@suse.com
- Update to 4.58
* The solution file format used by API routines glp_read_sol,
glp_write_sol, glp_read_ipt, glp_write_ipt, glp_read_mip, and
glp_write_mip was changed. For more details please see the GLPK
reference manual included in the distribution.
* The tan function (trigonometric tangent) was added to GNU
MathProg modeling language.
* A new version of the document "Modeling Language GNU MathProg"
in Spanish was included (in LaTeX and pdf formats).
* A check to determine if libtool needs '-no-undefined' flag to
build shared libraries on some platforms was added.
* A script to regenerate the configure script and the Makefiles
was added.
* Sun Nov 08 2015 mpluskal@suse.com
- Update to 4.57
* A new, more efficient implementation of the dual simplex method
was included in the package. This new implementation replaces
the old one, which was removed.
* Option sr_heur was added to struct glp_iocp to enable/disable
the simple rounding heuristic used by the MIP solver. Thanks to
Chris Matrakidis <cmatraki@gmail.com> for suggestion.
* New API routine glp_at_error was added and documented. Thanks
to Jeroen Demeyer <jdemeyer@cage.ugent.be> for suggestion.
* Some minor typos were corrected in the GLPK documentation.
Thanks to Anton Voropaev <anton.n.voropaev@gmail.com> for typo
report.
* An example application program TSPSOL was added. It uses the
GLPK MIP optimizer to solve the Symmetric Traveling Salesman
Problem and illustrates "lazy" constraints generation. For more
details please see glpk/examples/tsp/README.
* Fri Oct 02 2015 mpluskal@suse.com
- Update to 4.56
* A new, more efficient and more robust implementation of the
primal simplex method was included in the package. This new
implementation replaces the old one, which was removed.
* A bug was fixed in a basis factorization routine. (The bug
appeared if the basis matrix was structurally singular having
duplicate row and/or column singletons.) Thanks to Martin Jacob
* Scripts to build GLPK with Microsoft Visual Studio 2015 were
added. Thanks to Xypron <xypron.glpk@gmx.de> for contribution
and testing.
- Cleanup spec file with spec-clener
* Wed Nov 12 2014 dmitry_r@opensuse.org
- Update to version 4.55
* Bugfixes, documentation update. See NEWS file for details.
