<h2>General information</h2>

There are now 3 GRASS branches:
<ul>
<li>5.0 (CVS repository "grass", branch "releasebranch_26_april_2002_5_0_0").
<li>5.3 (CVS repository "grass", HEAD).
<li>5.7 (CVS repository "grass51", HEAD).
</ul>

<b>5.0</b> is the stable branch, from which the various 5.0.x releases are
derived. Future releases from this branch should contain only
bug-fixes or minor, backward-compatible improvements. 5.0.3
was released 6 November 2003. See See <a href=../grass5/index.html>related web pages</a>.
<br>
<b>5.3</b> is the development version of 5.0. It will include anything which
is added to the 5.0 branch (although such changes will typically go
into 5.3 initially, then get go into the 5.4 branch later), plus
some other changes which are too intrusive to go into the 5.0.x
releases (e.g. because they break backwards compatibility, or
introduce additional dependencies).
<br>
<b>5.7</b> is the experimental version which was previously referred to as
"5.1". See <a href=../grass51/index.html>related web pages</a>.
<P>
For features details, please refer to the <a href="../roadmap.html">Roadmap</a>.

<h2>Status of  version:</h2>
GRASS 5.3: no official release yet.

<h2>What's new in current release of GRASS 5.3.x?</h2>
<a href="source/NEWS.html">Read on the detailed NEWS list</a>.
For details please read the detailed changes <A HREF="source/ChangeLog">HISTORY</a>.

<h2>How stable is GRASS 5.3.x?</h2>

GRASS 5.3.x has been tested on Linux, MacOSX, WindowsNT/2000/XP and Silicon
Graphics Irix systems. Many people use it for daily production. HOWEVER,
there are likely still some <a href=http://intevation.de/rt/webrt?q_queue=grass>bugs</a> to be worked
out.

<li> You are kindly requested to send your comments about GRASS 5 functionality
  (recent version).
<li>List of <a  href="http://intevation.de/rt/webrt?q_queue=grass">known bugs 
 in this GRASS 5.3.x version</A>. Your help to fix these bugs is highly appreciated. If you find
 a bug, please check the list if it is already known. If not, you are kindly
 requested to report the bug(s) to use our new <a href="../bugtracking/bugreport.html">bug report form</a>
</ul>

<a name="cluster"></a>
<h2>Clustered GRASS GIS</h2>

GIS related work is regularly CPU-intensive - as CPU power becomes cheaper
nowadays, GRASS might be run in clustered environments. There are several
options to parallelize GRASS:

<ul>
<li><a href=http://openmosix.sourceforge.net/>openMOSIX</a>: To run GRASS
on an openMOSIX cluster,
there is no need to modify GRASS or to link with any library, or even
to assign processes to different nodes. You can run GRASS in parallel
sessions (same location, different mapsets) which will be sent to the
various cluster nodes.
However, individual modules will be run serially on one CPU. So this is more
load-balancing than a real cluster. It should be quite easy to set up.
<li><a href=http://www.beowulf.org>Beowulf Cluster</a>: Requires GRASS
modifications not done yet.
<li>GRASS 5 contains the "gmath" library which contains wrapper functions to
the numerical libraries <a
href=http://www.netlib.org/lapack/>LAPACK</a>/<a
href=http://www.netlib.org/blas/>BLAS</a> which also exists in a
parallelized form <a
href=http://www.cs.utexas.edu/users/plapack/>PLAPACK</a> and <a
href=http://www.netlib.org/scalapack/pblas_qref.html>PBLAS</A> and <a
href=http://www.netlib.org/scalapack/>ScaLAPACK</a>. However, further
work has to be done to utilize the LAPACK/BLAS functions within GRASS.

Go to the <b><a href="../download.html">download page</a></b> and start downloading!<p>
<p>
<b>Some additional tidbits you may need...</b>
<ul>
<li>TclTkGRASS needs the Tcl and Tk libraries 8.x or later to run
<li>r.in.tiff needs the <a href="http://www.libtiff.org">libtiff</a> and <a
href=ftp://ftp.freesoftware.com/pub/infozip/zlib/index.html>libz</a> (usually already
existing on Linux systems)
<li>r.in.png/r.out.png need the <a href=http://www.libpng.org/pub/png/>PNG library</a>
<li> NVIZ and r3.showdspf use the <a href="http://mesa3d.sourceforge.net/">Mesa 3D</a> OpenGL clone
