merge 39755 41211 thanks Thanks for the report. I tried updating texlive-lualatex-otfload a while back, but gave up because the new versions needs "l3build" which I have zero experience with. Any pointers for packaging and using l3build appreciated.
For reference, as the original home page has been archived, here is the updated repository with support for Tex Live 2019 and later: https://github.com/latex3/luaotfload
