GRASS Development team led by Markus Neteler has released 5.0.0 GRASS Geographic Information System.
GRASS 5 is OSI Certified Open Source software. Baylor University has long been associated with GRASS development efforts and the GRASS community appreciates and acknowledges that support.
In addition to traditional Unix platforms such as Linux, Solaris and IRIX, experimental versions of GRASS 5 also run under Microsoft Windows using the Cygwin tools and Apple Macintosh OS-X , also known as Darwin. It was also ported to handheld devices such as Compaq/iPAQ and SHARP/Zaurus.
This new version is the first major change in GRASS functionality since GRASS 4 was released several years ago. Notable improvements include support for floating point and null values. Users can opt to use a new windowing interface based on Tcl/Tk on those platforms supporting X Window.
