What is new in FargoFit since the last publicly available version was released? FargoFit 3.16.0.0 - Copy protection is removed from program. Program doesn't require license file to work in full mode. FargoFit 3.15.8.0 - Fixed bug with displaying information in property table FargoFit 3.15.7.0 and earlier - Code of Marquardt minimization algorithm was optimized for using the full power of multicore and multiprocessor computers. The speed of calculation is several times higher. - Format of program license file was changed. Old license files are no longer supported by new version of the program. - Demo mode was added. Fitting is disabled in demo mode. - Excessive functionality was removed: weighted R0 shifted time origin for data graph aka "Happy Dave" random parameter values generation secondary parameters dialog. - Form About was rebuilt; computer ID was added. - File extension .ff is automatically associated with the program. - Graphs can be copied to clipboard as metafiles. - Special dialog with check boxes is now used to control column visibility in Data View, as opposed to menu items in the past. - Window with plot of parameter value vs experiment condition is not longer a modal dialog so user can open as many of them as necessary. - Indication of currently focused cell as well as a navigation using arrow keys was added to parameters table. - Temperature depended energy activation model was added to fraction kinetic. - Background is recalculated after applying time shift to IRF for more precise calculation. - First moment is calculated and reported in property table of IRF and signal waveforms (Helpful for rough averaged lifetime estimation). - Fixed error in customized Open File dialog with data preview. - Fixed error in copy data operation of Data View window. - Fixed error in using standard deviation from data file as weighting factor for goodness of fit calculation. - Fixed error in using Dead Time parameter. - Fixed error in Model Designer window. Model was previously considered as changed when this window was just opened. - Fixed error in advanced parameters unlinking routine. - Added support of Becker-Hickl .sdt files
