You can download a source tarball for gnuplot version 4.2.5 from the 
gnuplot development site on SourceForge.

	http://sourceforge.net/project/showfiles.php?group_id=2055


Installation
------------
Installation instructions are available in the source itself; the short
version for linux/unix-like systems is to unpack the tarball and then
build it:
		cd gnuplot-4.2.5 ; ./configure ; make
test it:
		make check
install it:
		make install


Known issues
------------

- Internationalization and locale support is incomplete in this version.
  If you encounter problems with character encodings, numerical formats,
  or other locale issues, try the CVS version on SourceForge.

- Octave has recently changed its method of sending data to gnuplot for
  plotting; data is passed in-line through the pipe to gnuplot's stdin.
  Unfortunately, the current Gnuplot 4.2 code does not support mouse
  interaction with in-line data.  This problem is fixed in the CVS
  version, but not in the current release version 4.2.5.

Support
-------
Please report all bugs and installation problems to the bug tracker
on SourceForge:

	http://sourceforge.net/tracker/?group_id=2055&atid=102055

There is also an active gnuplot discussion forum on usenet group

	comp.graphics.apps.gnuplot

Development
-----------
Gnuplot development is quite active. The development branch (4.3) on 
SourceForge contains preliminary implementations of many new features.
This branch will eventually be released either as version 4.4 or 5.0.
Feedback and contributions of code are very welcome.
