*Press Release
The GRASS Development Team announces* GRASS GIS 6.4.0 released
 We are pleased to announce the release of GRASS GIS
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

GRASS 6.4 brings a number of exciting enhancements to the GIS. Our new
graphical user interface* (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.

Due to the freshness of *WinGrass* 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.

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 http://grass.osgeo.org, or from many local
mirrors worldwide. In addition to the extensive documentation which comes
with the software, our Wiki help system
<http://grass.osgeo.org/wiki>contains a wealth of user supplied tips
and tricks, tutorials, and guides.

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.
About GRASS GIS The *Geographic Resources Analysis Support System*, 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.

GRASS is a founding member of The Open Source Geospatial
Foundation<http://www.osgeo.org/>(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.

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 GNU General Public
License <http://www.gnu.org/licenses/gpl-2.0.html>.

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.
