The Billinge group and diffraction sub-group of the DANSE project
are pleased to announce the new code release DiffPy-1.0-r3067.
The distribution includes PDFgui and PDFfit2 programs for real-space
structure refinements to atomic pair distribution functions (PDFs).

This release is our first non-beta release and existing
users of PDFgui and PDFfit2 software are recommended to upgrade
to this version. Of course, this release is also recommended for new users!

The new features in the PDFgui program include improved particle shape
factors, addition of 249 space group representations, improved
installation and update procedure and many bugfixes.  For a detailed
list of changes see the "What is new" section in the PDFgui manual at

   http://www.diffpy.org/doc/pdfgui/pdfgui.html

The DiffPy release can be installed on Unix-like systems such as
Linux, Mac OSX and on Windows.  For more information and for
software download see

   http://www.diffpy.org/

There is no charge to use the software, though if you use the program
we ask that you cite the following paper in all resulting publications:

   C. L. Farrow, P. Juhas, J. W. Liu, D. Bryndin, E. S. Bozin,
   J. Bloch, Th. Proffen and S. J. L. Billinge, PDFfit2 and PDFgui:
   Computer programs for studying nanostructure in crystals,
   J. Phys: Condens. Matter 19, 335219 (2007).

A users community forum where you can post questions, which will be
answered by the developers and which are archived for future users,
can be found at

   http://groups.google.com/group/diffpy-users

We hope you enjoy using the program.  We welcome feedback in the form
of bug reports and feature requests which we will try and respond to
as best as we can.

Please also let us know about your successes. This development was
funded in part by NSF [*] through the DANSE project, http://danse.us/
(DMR-0520547), and we/they need to hear how the community is using
the software.  Future NSF funding of software development depends
critically on such feedback, so please don't be shy on sharing
any success stories enabled by the software.  If you are unhappy
posting these to diffpy-users, please send them to
Prof. Simon Billinge at <sb2896 at columbia.edu>.

[*] Any opinions, findings, and conclusions or recommendations
   expressed in this material are those of the author(s) and
   do not necessarily reflect the views of the NSF.
