GLPK 3.2.1 -- Release Information
Release date: Aug 12, 2002
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 includes a preliminary implementation of the branch-and-cut
framework, which is a set of data structures and routines intended for
developing branch-and-cut methods for solving mixed integer and
combinatorial optimization problems.
Detailed decsription of the branch-and-cut framework is given in the
document "GLPK: A Preliminary Implementation of the Branch-And-Cut
Framework" included in the distribution (see the file 'brcut.txt' in
the subdirectory 'doc').
In order to illustrate how the GLPK branch-and-cut framework can be
used for solving a particular optimization problem there is an example
included in the package. This is a stand-alone program, TSPSOL, which
is intended for solving to optimality the symmetric Traveling Salesman
Problem (TSP), a classical problem of the combinatorial optimization
(see the file 'tspsol.c' in the subdirectory 'sample').
Please note that the current version of GLPK is tentative.
See GLPK webpage at <http://www.gnu.org/software/glpk/glpk.html>;.
GLPK distribution can be ftp'ed from <ftp://ftp.gnu.org/gnu/glpk/> or
from some mirror ftp sites; see <http://www.gnu.org/order/ftp.html>;.
Checksum is the following:
GLPK is also available as a Debian GNU/Linux package. See the webpage
GNU Radius 0.96.4 is released. This is a maintenance release introducing
some new features.
GNU Radius is a set of tools for remote user authentication and accounting.
The package includes server daemon, various client utilities, and a set of

Patches and source tarballs are available at
GNU Radius is available from ftp://ftp.gnu.org/gnu/radius and
and its usual mirror sites; see http://www.gnu.org/order/ftp.html.

The list of user-visible changes follows:
* The syntax of the "rewrite" language is extended. It
supports addressing multiple attributes in a request and
deleting arbitrary attributes.
* Fixed bug in "rewrite" optimizer, which caused boolean
short-cuts (|| and &&) to malfunction.
* Added support for sybase and SecurID (thanks to Steve Bleazard)
* Introduced new Auth-Type value Ignore. It causes the incoming request
to be dropped.
* Configurable comparison of the requests allows to detect duplicate
requests even if the NAS changes request ID or authenticator between
* Fixed bug in formatting A/V pairs for detailed logging which
caused radiusd to dump core upon receiving certain vendor-specific
* If the incoming request does not contain NAS-IP-Address attribute,
it is generated and added to it.
* Fixed bug in handling Expiration attribute
WHAT IS LilyPond?
LilyPond is the GNU Project music typesetter. LilyPond produces
beautiful sheet music using a description file as input. Documentation
and examples can be found on
This release is focused on improved output quality: some pieces of
output now have publication quality. To achieve this, we have
completely overhauled the spacing engine, the font and the beaming
Version 1.6 also adds support for drum notation, figured bass,
tablature and (limited) ancient notation, piano notation.
NEW SINCE 1.4
* Support for figured bass and tablature.
* Completely rewritten beam formatting: provides much better output
* Completely revised and improved music font.
* Completely rewritten MIDI import support.
* Completely rewritten grace note support. Practically speaking this means
that grace notes can be slurred to normal normal notes.
* Improved accidental handling and formatting: styles for producing
cautionaries may vary, and complex collisions between accidentals of a
chord are handled much better.
* Better spacing: both globally and locally. This includes subtle
details like optical stem spacing.
* More support for ancient notation: mensural ligatures, ambitus
(pitch range) of voices, more shapes, etc.
* More support for piano notation: bracket pedals, directed arpeggios,
* Easier music polyphonic music entry.
* More extensibility, many speedups and bugfixes
* The manual has been thoroughly revised.
* Development is now hosted at http://savannah.gnu.org, and sources
can be downloaded through anonymous CVS.
* Support for windows: LilyPond is part of the cygwin distribution,
which comes with a user-friendly installer.
Sources for this project are available at
Packages for Red Hat Linux 7.x/i386 are available from
A Debian GNU/Linux package for unstable should be available shortly
A package for Windows should be available shortly though Cygwin's
A package for MacOS X should be available though fink shortly
For other UNIX/Linux distributions (SuSE, Mandrake, *BSD, etc),
ask your vendor or compile from source.
