Hi Everyone, I've just posted Ifeffit version 1.2.3. As with earlier versions in the 1.2.x series, this is a bug-fix release. The changes are: 1) setting 'path_index' now causes the given path to be the 'current path', so that 'reff', 'degen', and any parameters that might depend on them are automatically updated. 2) spline() now passes all of the arguments to pre_edge() correctly. There is now an updater program for Windows is now available. If you already have 1.2.2 installed, you do not need to download the 30Mb full installation, just the 2Mb program ifeffit_update-1.0.exe from either http://cars9.uchicago.edu/ifeffit/download.html or https://sourceforge.net/project/showfiles.php?group_id=80919 Once installed, the updater program will automatically run just before all Ifeffit applications, checking whether updates are available and installing them if desired. This should make it a lot easier to keep up-to-date with the latest versions of Ifeffit, athena, artemis, sixpack, etc... If you have any questions or trouble, let me know, --Matt
