Renoise uses LuaJIT (which as I understand is roughly Lua 5.1) but some of the API docs point to 5.4. Not a huge deal but it can be misleading.
Where exactly?
Oh, looks like this is specifically an issue with the Markdown docs from the xrnx repo. I thought there was a 1:1 correspondence between these and the site but that does not seem to be the case. Specifically, global.md and os.md include links to the 5.4 docs.
