29We are pleased to announce the release of
30 <a href="http://grass.osgeo.org">GRASS GIS 6.4.0</a>, the first in the
31new line of 6.4 stable releases. As a stable release 6.4 will enjoy
32long-term support. The next release (6.4.1) will introduce a few new
33features which are still undergoing final testing, but after that all
34further 6.4 releases will be bugfix-only. Due to our highly conservative
35stabilization policy this is the first official version of GRASS to
36introduce new features since October 2006 and supersedes the previous
37stable line of GRASS 6.2. As such the floodgates are open and there are
38many new features to explore and many new structural improvements to be
39found in the software.
40
41<p>
42GRASS 6.4 brings a number of exciting enhancements to the GIS. Our new
43<em>wxPython graphical user interface</em> (wxGUI) is debuted, Python
44is now a fully supported scripting language, and for the first time
45since its inception with a port from the VAX 11/780 in 1983, GRASS
46will now run natively on a non-UNIX based platform: MS-Windows!
47
48In addition to bringing the software to a host of new users, the ability
49to run GRASS on any common computer platform furthers our goal of open
50access to the software. We hope you will enjoy the ability to use this
51program on the systems that are most convenient to you and your work.
52
53<p>
54Due to the freshness of <em>WinGrass</em> there may still be a few rough
55edges yet to discover, but after more than a year of dedicated testing
56and quality-assurance review we are very pleased with the results.
57Users can be confident to use this version for their day to day work,
58indeed due to the open development model many already do. Existing UNIX
59and Mac users will be happy to know that these new features do not disrupt
60the base GIS which remains as solid as ever and fully backwards compatible
61with earlier GRASS 6.0 and 6.2 releases. The venerable Tcl/Tk
62GUIs are also still available if you prefer to use them.
63
64<p>
65The GRASS software including over 400 built-in analysis modules and 100 community
66supplied add-on modules and toolboxes can be downloaded for free from the
67main GRASS website at
68 <a href="http://grass.osgeo.org">http://grass.osgeo.org</a>, or from many
69local mirrors worldwide. In addition to the extensive documentation which
70comes with the software, our
71 <a href="http://grass.osgeo.org/wiki">Wiki help system</a>
72contains a wealth of user supplied tips and tricks, tutorials, and guides.
73
74<p>
75Since 6.4 entered the testing phase work has begun on GRASS 7 and is
76progressing rapidly, including many new wxGUI improvements and tools
77which we hope to bring over for the upcoming 6.4.1 release.

80<h3>About GRASS GIS</h3>
81
82The <i>Geographic Resources Analysis Support System</i>, commonly referred to
83as GRASS, is a Geographic Information System (GIS) providing powerful raster,
84vector, and geospatial processing engines in a single integrated software
85suite. GRASS includes tools for spatial modeling, visualization of raster and
86vector data, management and analysis of geospatial data, and the processing of
87satellite and aerial imagery. It also provides the capability to produce
88sophisticated presentation graphics and hardcopy maps. GRASS has now been
89translated into twenty languages and supports a huge array of data formats.
90
91<p>
92GRASS is a founding member of <a href="http://www.osgeo.org">The Open
93Source Geospatial Foundation</a> (OSGeo), a non-profit legal entity which
94has enjoyed extraordinary growth. We expect that this formal infrastructure
95will guarantee that the GRASS community will be well supported and vibrant
96far into the future.
97
98<p>
99GRASS is currently used around the world in academic and commercial settings
100as well as by many governmental agencies and environmental consulting companies.
101It runs on a variety of popular hardware platforms and is Free open-source
102software released under the terms of the
103<a href="http://www.gnu.org/licenses/gpl-2.0.html">GNU General Public License</a>.
104
105<p>
106Users are encouraged to study, customize, extend, improve, and (if
107necessary) diagnose and repair the inner workings of any part of the program.
108We believe that scientific progress depends on the reproducibility of results,
109which in turn depends on the unhindered ability of the user to know, evaluate,
110double-check, and learn from all algorithms and methodologies used in the process
111of their work.

124full UNIX support via Cygwin), Sun Solaris (SPARC/Intel), Silicon Graphics
125Irix, HP-UX, DEC-Alpha, AIX, the BSD family, iPAQ/Linux and other UNIX
126compliant platforms. GRASS runs on both 32 and 64 bit systems with large
