GRASS GIS 6.4.1 released 12 April 2011 http://grass.osgeo.org We are pleased to announce that the new stable version of GRASS GIS 6.4.1 has been released. This release fixes some bugs discovered in the 6.4.0 source code and adds a few new features (over 560 updates to the source code with respect to 6.4.0 have been added). As a stable release series the 6.4 line will enjoy long-term support. GRASS 6.4.1 brings a number of incremental enhancements to the 6.4 stable series of releases. The new wxPython graphical user interface (wxGUI) has been updated with a load of new features and tools; Python is now a fully supported scripting language, including a python toolkit and hooks back into the core GIS libraries; and MS-Windows support continues to mature. GRASS differs from many other GIS software packages used in the academic and professional worlds in that it is developed and distributed by users for users, mostly on a volunteer basis, in the open, and is given away for free. The source code is also freely available, allowing for immediate customization, examination of the underlying algorithms, addition of new features, and faster patching of bugs.
