Thank you. I haven't checked out your release but the latest ryjin already uses nsz.exe so I think it is compatible with your latest build. Thank you @nicoboss for keeping nsz updated. Your work and @blawar really made the scene move forward.@GnK23 New NSZ release: https://github.com/nicoboss/nsz/releases - see all this new features - I guess you should update RYJIN too. With nsz 2.1 the project got pip support so if you like you can fully separate NSZ and RYJIN by using NSZ as a library. Just enter "pip install nsz" to get NSZ. Also note NSZ 2.1.1 now finally officially includes a portable build for windows so the user no longer requires python.
