Hi
this patch is based on 1.2.10, the latest version is 1.2.11, not sure
what the difference is but there might be something overlooked. The website
https://www.libspf2.org/
is 1.2.10 (seems not to be updated)
where github is the
https://github.com/shevek/libspf2
1.2.11
I believe 1.2.11 was launched in 2021.
