OSGeo announces the release of a new stable version of GRASS GIS. This release fixes bugs discovered in version 6.4.1 of the program and adds a number of new features. This release includes over 760 updates to the source code since 6.4.1. 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.

The new wxPython graphical user interface (wxGUI) has been updated with many new features and tools. Python is now a fully supported scripting language, including an updated Python toolkit to simplify
the authoring of personal scripts, support for NumPy based array calculations, and a Python application interface for the GRASS C libraries. Additionally, MS-Windows support continues to mature.

GRASS 6.4.2 debuts ten new modules, a new GUI cartographic composer tool, a new GUI object-oriented modeling environment, and improved infrastructure for installing community supplied add-on modules.
