This is how I understood it as well but toms comment and the download page make me think otherwise now. I find it strange that they never explicitly mentioned switching versions for the current stable edition. The release for 1.21 mentions the switch in the update notes but nothing for 1.20, unless I missed something else.
No worries, my eyes are broken or lazy, I swear it said .net7 when I downloaded but yeah, just checked and see that it does refer to .net 8. Wiki has yet to be updated.
