This version is ready for use by students (and everyone else, of course) from February 2022.
SFGrapher.deb has been tested on Ubuntu 20.0.4.3 LTS, SFGrapherSetup.exe on Windows 10, and SFGrapher.dmg on MacOS Monterey.
High-DPI-Hotfix for Windows: If you have a high-resolution display and SFGrapher looks too small, use SFGrapherSetup_high_dpi_hotfix.exe
Warning for MacOS: When you quit the application, you may get an error message telling you that Python has crashed. I have no clue why this is so, but it is harmless. You will not lose data, the crash happens after the application closes.
MacOS on M1 processors: For some reason the SFGrapher.dmg does not work even if installed through Rosetta. However, doing the Run in a Python environent as described in https://github.com/hanspi42/signalflowgrapher#readme inside a Rosetta terminal should work.
