Currently, there are two main versions of SoFi operational: SoFi 9 for Igor 9 and SoFi 10 for Igor 10. While SoFi 8 is currently still available and supported, we will stop the support of SoFi 8 somewhen during 2026. We discontinued SoFi 6 long ago in 2021, therefore please be aware that if you are still using SoFi 6 there are critical bugs in SoFi 6 (SoFi_history). All new features will only be released in SoFi 10. If the required Igor functions are also available in Igor 9, the features will also be available in SoFi 9. The SoFi keys are fully compatible throughout all SoFi versions.

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!
