Hi everyone,

Today I am announcing my first official release of my latest version
of my XAS data processing and analysis software.  The package is
called Demeter, the version number is 0.9.9, and it includes new
versions of Athena, Artemis, and Hephaestus.  In many ways, these are
much like the versions of the software that have been in use for
almost a decade.  In many ways, however, they offer important
improvements, including better plotting, prettier GUIs, and lots of
new analysis features.

For those using Windows, you can download the installer package from


For those using Linux, installation instructions can be found at


I am hoping that installer packages for the Mac and for specific Linux
distributions will become available in the coming months.

The Demeter versions of the programs can coexist on a computer with
the old versions.  New Athena and old Athena peacefully coexist,
indeed, they use the same project file format.  The project file
format for new Artemis is different, however new Artemis can import
project files from old Artemis.

I am no longer developing the old versions.  I will no longer fix bugs
or add new features to the old versions.  All of my future develop
efforts will be devoted to the new versions.

Here are some useful links:

It has been a joy to develop and support my software over the years.
My interactions with the kind, engaged people in the community of
Ifeffit users have been among the high points of my career.  I hope
that you enjoy my new software as much as I enjoyed writing it.
