Hi Folks, I've posted Ifeffit 1.2.7, including a new Windows installer, source code, and a Mac Binary installer (currently OS 10.3 only) on the IFeffit Web Page. I'll post these to sourceforge.net as soon as I can. For Windows users, there is also an automatic update that may be downloaded and installed. The changes to the ifeffit library are small: a few bugfixes, added a 'penalty()' math function (as per a discussion on this list about restraints) and an improved mechanism for ifeffit to report its status to a calling program like Athena and Artemis. The Windows and Mac installers also include the latest versions of Bruce's Athena, Artemis, and Hephaestus. There are still some known issues with "PAR-" files from Bruce's codes on Windows. Bruce and I think we can solve this, and are aiming to release a new Windows installer sometime in the next month (or so) that fixes this and cleans up some of the messiness of the Windows installer. --Matt
