Stable GRASS GIS 6.4.3 released - Birthday release for 30 years of GRASS GIS

News Date: 
30 Jul 2013

We are pleased to announce the release of a new stable version of GRASS GIS. This release fixes bugs discovered in 6.4.2 version of the program and adds a number of new features. This release includes over
830 updates to the source code since 6.4.2. As a stable release series, the 6.4 line will enjoy long-term support and incremental enhancements while preserving backwards-compatibility with the entire GRASS 6 line.

Key improvements of this release include some new functionality (assistance for topologically unclean vector data), major speedup for some vector modules, fixes in the vector network modules, fixes for the wxPython based portable graphical interface (attribute table management, wxNVIZ, and Cartographic Composer). A number of new modules have been added for processing LANDSAT and MODIS satellite data, and a new vector statistics module is also introduced. Many new symbols and north arrows are available, and the user will find an improved and easier to use wizard for creating custom project locations with precise map projection and datum support. Community-contributed add-on modules are now more easily and robustly installed from an online archive. Other major developments include enhancements to the Python scripting library and numerous software-compatibility fixes and translation updates. Important is the enhanced portability for MS-Windows (native support, fixes in case of missing system DLLs). And we welcome Romanian as our twenty-fourth language!
