Currently, the two main versions of SoFi that are operational in Igor, i.e., SoFi 8 for Igor 8 and SoFi 9 for Igor 9. We discontinued SoFi 6. All new features will only be released in SoFi 8 and SoFi 9, e.g., the generalized import panel. In the near future, there might be feature that will only be available in SoFi 9 due to Igor. The SoFi keys running in Igor 6 are also fully compatible with SoFi 8 and SoFi 9.
There might be cases and conditions that have not been tested or encountered during our test phases, and that might cause some unexpected problems on SoFi or Igor. We apologize for this eventuality and we greatly appreciate bug reports! Thanks already in advance for your feedback. Any feedback, no matter what, is always highly appreciated!
