<br><br><center><b>Press Release<br>The GRASS Development Team announces</b>
<h2>GRASS GIS 6.4.0 released</h2>
</center>
<br>
<table align="center" bgcolor="#efefef" cellpadding="40" width="80%"><tbody><tr><td>
We are pleased to announce the release of
<a href="http://grass.osgeo.org/" target="_blank">GRASS GIS 6.4.0</a>, the first in the
new line of 6.4 stable releases. As a stable release 6.4 will enjoy
long-term support. The next release (6.4.1) will introduce a few new
features which are still undergoing final testing, but after that all
further 6.4 releases will be bugfix-only. Due to our highly conservative
stabilization policy this is the first official version of GRASS to
introduce new features since October 2006 and supersedes the previous
stable line of GRASS 6.2. As such the floodgates are open and there are
many new features to explore and many new structural improvements to be
found in the software.
<p>
GRASS 6.4 brings a number of exciting enhancements to the GIS. Our new
<em>wxPython graphical user interface</em> (wxGUI) is debuted, Python
is now a fully supported scripting language, and for the first time
since its inception with a port from the VAX 11/780 in 1983, GRASS
will now run natively on a non-UNIX based platform: MS-Windows!
In addition to bringing the software to a host of new users, the ability
to run GRASS on any common computer platform furthers our goal of open
access to the software. We hope you will enjoy the ability to use this
program on the systems that are most convenient to you and your work.
</p><p>
Due to the freshness of <em>WinGrass</em> there may still be a few rough
edges yet to discover, but after more than a year of dedicated testing
and quality-assurance review we are very pleased with the results.
Users can be confident to use this version for their day to day work,
indeed due to the open development model many already do. Existing UNIX
and Mac users will be happy to know that these new features do not disrupt
the base GIS which remains as solid as ever and fully backwards compatible
with earlier GRASS 6.0 and 6.2 releases. The venerable Tcl/Tk
GUIs are also still available if you prefer to use them.
</p><p>
The GRASS software including over 400 built-in analysis modules and 100 community
supplied add-on modules and toolboxes can be downloaded for free from the
main GRASS website at
<a href="http://grass.osgeo.org/" target="_blank">http://grass.osgeo.org</a>, or from many
local mirrors worldwide. In addition to the extensive documentation which
comes with the software, our
<a href="http://grass.osgeo.org/wiki" target="_blank">Wiki help system</a>
contains a wealth of user supplied tips and tricks, tutorials, and guides.
</p><p>
Since 6.4 entered the testing phase work has begun on GRASS 7 and is
progressing rapidly, including many new wxGUI improvements and tools
which we hope to bring over for the upcoming 6.4.1 release.
</p><h3>About GRASS GIS</h3>
The <i>Geographic Resources Analysis Support System</i>, commonly referred to
as GRASS, is a Geographic Information System (GIS) providing powerful raster,
vector, and geospatial processing engines in a single integrated software
suite. GRASS includes tools for spatial modeling, visualization of raster and
vector data, management and analysis of geospatial data, and the processing of
satellite and aerial imagery. It also provides the capability to produce
sophisticated presentation graphics and hardcopy maps. GRASS has now been
translated into twenty languages and supports a huge array of data formats.
<p>
GRASS is a founding member of <a href="http://www.osgeo.org/" target="_blank">The Open
Source Geospatial Foundation</a> (OSGeo), a non-profit legal entity which
has enjoyed extraordinary growth. We expect that this formal infrastructure
will guarantee that the GRASS community will be well supported and vibrant
far into the future.
</p><p>
GRASS is currently used around the world in academic and commercial settings
as well as by many governmental agencies and environmental consulting companies.
It runs on a variety of popular hardware platforms and is Free open-source
software released under the terms of the
<a href="http://www.gnu.org/licenses/gpl-2.0.html" target="_blank">GNU General Public License</a>.
</p><p>
Users are encouraged to study, customize, extend, improve, and (if
necessary) diagnose and repair the inner workings of any part of the program.
We believe that scientific progress depends on the reproducibility of results,
which in turn depends on the unhindered ability of the user to know, evaluate,
double-check, and learn from all algorithms and methodologies used in the process
of their work.

full UNIX support via Cygwin), Sun Solaris (SPARC/Intel), Silicon Graphics
Irix, HP-UX, DEC-Alpha, AIX, the BSD family, iPAQ/Linux and other UNIX
compliant platforms. GRASS runs on both 32 and 64 bit systems with large
data file (>2GB) support for most key modules.
