GRASS GIS 6.4.6 released


We are pleased to announce the new stable release of GRASS GIS 6.4.6

Eleven years after the release of GRASS GIS 6.0.0, after 6 years of developement of the GRASS GIS 6.4.0 and two fruitful community sprints before and after the FOSS4G 2016 conference in Bonn we are pleased to announce the last release of the GRASS GIS 6 line: GRASS GIS version 6.4.6. This means that there will be no further bugfixing release for GRASS GIS 6.

We kindly invite all users to upgrade to the bright and shiny GRASS GIS 7 and benefit from the newest improvements. It was released over 18 months ago and the fifth bug fixing release, GRASS GIS 7.0.5, is about to be released. And a new version 7.2.0 is currently in release candidate state.

About GRASS GIS

The Geographic Resources Analysis Support System (http://grass.osgeo.org/), commonly referred to as GRASS GIS, is an Open Source Geographic Information System providing powerful raster, vector and geospatial processing capabilities in a single integrated software suite. GRASS GIS 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 GIS has been translated into about twenty languages and supports a huge array of data formats. It can be used either as a stand-alone application or as backend for other software packages such as QGIS and R geostatistics. It is distributed freely under the terms of the GNU General Public License (GPL). GRASS GIS is a founding member of the Open Source Geospatial Foundation (OSGeo).
