I actually have a few ideas for the unimplemented areas of https://github.com/olsak/OpTeX/pull/67. Will see how that goes, but IIRC `luaotfload` doesn't allow font files with `.lua` extension, while the original...

> Suppose that we have such package, say its name is `fntloader`. First of all, we need a maintainer of such package. I don't feel like doing it. I am...

Sorry for not responding earlier, but see my recent description of the tectonic update process: https://github.com/tectonic-typesetting/tectonic-staging/pull/17#issuecomment-973553526.

I am not a nicematrix user, but this is my understanding: This is due to use of different versions of the nicematrix package. Your XeLaTeX comes most likely from TeX...

Packages can disable the destination rewriting with `\special{dvipdfmx:config C 0x0010}`, `hyperref` already does. With https://github.com/tectonic-typesetting/tectonic/pull/953 Tectonic will also support it. AFAIK we would be following upstream here (with regards to...

Please note that `tectonic` is no different from normal `xetex` - this TeX engine produces only `.xdv` (extended DVI) files by itself. But usually behind the scens the file is...

In this case, the `pdfx` package should be updated in upstream, its suggestions for ordinary XeLaTeX users are outdated, as is its `\pdfcreationdate` primitive check. If we wanted to help...
