Consider this LaTeX document: \documentclass{article} \usepackage{array} \begin{document} Hello World! \end{document} When build with latex in fedora 44, it produces this warning: > LaTeX Warning: You have requested release `2026/06/01' of LaTeX, > but only release `2025-06-01' is available. > This did not occur in Fedora 43. Reproducible: Always Steps to Reproduce: 1. As in details, attempt to use the array package in a LaTeX document 2. Build the LaTeX document Actual Results: Build reports: > LaTeX Warning: You have requested release `2026/06/01' of LaTeX, > but only release `2025-06-01' is available. Expected Results: Document builds without special warings
Does it succeed properly despite the warning? I can either roll it back to an older version or I can patch out the release check (or I can push TL2026 into Fedora 44, but I'm probably not doing that).
I know I just said I probably wasn't going to do this, but... the cleanest fix here would be to bring TeXLive 2026 (texlive-base) into Fedora 44, so I've asked FESCo for permission to do that: https://pagure.io/fesco/issue/3576 I suspect this is the tip of a larger iceberg, and I'd rather not make random Fedora users find more of it.
Well, as it turns out, this array code prefers to use the Latex2e dev code, not even what's current in Latex2e, but it seems to fallback to the older array code logic (/usr/share/texlive/texmf-dist/tex/latex/tools/array-2024-06-01.sty ... i think) and succeeds. I believe this warning is annoying, but harmless, as my testing results in working PDF files here (which is better than it did before we updated array where it was breaking with TL2025. What a mess. I still think bringing TL2026 back to Fedora 44 is good, but it won't resolve this error message.

TeX is full of them and while I also desire to see fewer of these... this one might be one we just have to live with.

I think I know the cause of the warning message. texlive-latex-tools package of Fedora 44 contains mostly the same .sty files as texlive-latex-tools-dev. texlive-latex-tools is supposed to have compatible style files with latex version provided in texlive-latex-base, namely, "LaTeX2e <2025-11-01>". Overwriting /usr/share/texlive/texmf-dist/tex/latex/tools with that from upstream CTAN texlive-latex-tools should resolve the version mismatch. Hope this helps.
