Hi Everyone, The Windows installer for ifeffit 1.2.0 is now available at the Ifeffit homepage. This is now officially the "stable" version, but I want to stress that there may still be bugs (in fact, there is a serious bug still in Feff6L!!!), and that "stable" means that changes to the core library will attempt to follow the principle of "first, do no harm". Also, the sourceforge.net site for Ifeffit now has the latest versions of the stable source and windows executables at http://sourceforge.net/projects/ifeffit/ --Matt
