Hi,
After a recent upgrade of TeX Live in Debian/unstable
(2025.20251127 snapshot?), the following LaTeX file fails
to compile:
\documentclass{article}
\usepackage{amsopn}
\DeclareMathOperator{\Fast2Sum}{Fast2Sum}
\begin{document}
$\Fast2Sum(X)$
\end{document}
with an error on the \DeclareMathOperator.
This is due to the "2" in the operator name \Fast2Sum.
However, in
https://mirrors.ctan.org/install/macros/latex/required/latex-amsmath.tds.zip
I cannot see any corresponding change mentioned in "changes.txt".
So I'm wondering where this has changed in TeX Live and whether
this is a change done on purpose. In the latter case, where is
this change documented?
