The Geographic Resources Analysis Support System, commonly referred to as GRASS GIS, is a Geographic Information System (GIS) used for data management, image processing, graphics production, spatial modelling, and visualization of many types of data. It is free software released unter GNU General Public GPL (GNU General Public License).
Platforms supported by GRASS:
Linux, Sun Solaris, Sun Solaris/Intel, Silicon Graphics Irix, HP-UX, DEC-Alpha, PowerPC, MacOS X, AIX, BSD, CRAY and other UNIX compliant platforms (32/64bit), experimentally Windows NT/2000 running Cygnus
Where to get the new release:
and on the mirrors (Australia (local only) | Belgium | Croatia | Italy | Japan | Germany | Poland | Slovakia | South Korea | Taiwan | Thailand)
The new source code is available, selected binaries will be build the next days.
The general focus of this release is stability and reliability beside improving the functionality. Proposed major changes in vector and attribute management are scheduled for GRASS 5.1.

The full ChangeLog is also available.
What's new in GRASS 5.0.0pre2:
GRASS Upgrade NOTE: In case you upgrade from GRASSbeta1..beta11,
you have to convert the floating point raster data. Due to a copyright
violation we had to change the internal raster compression format. Luckily
the tool "r.lzw2z" exists which allows to automatically convert a complete
location. Find more information here!.
If you face a raster map reading problem in GRASS 5.0.0pre2, you have to
update the floating point raster maps with "r.lzw2z".
Again: this change is only needed if you upgrade from GRASSbeta1..beta11 to the current version. GRASS 4.x data can be read directly, consider to run "r.support" and v.support".
We hope you enjoy the ongoing development.
