Description
The output of\MFUsentencecase is no longer the same as in the manual. For example,
\MFUblocker{\nameref}
\makefirstuc{\nameref{sec:sentencecase} section} /
\MFUsentencecase{\nameref{sec:sentencecase} section}
now gives Sentence-Case section / Sentence-Case section, i.e. the output of \makefirstuc and \MFUsentencecase are the same. There was an update to the \text_titlecase... commands since the last release of this package, which may be the cause of the change in output.MWE

\documentclass{article}
\usepackage{mfirstuc}
\usepackage{nameref}
\begin{document}
\section{Sentence-Case}
\label{sec:sentencecase}
\MFUblocker{\nameref}
\makefirstuc{\nameref{sec:sentencecase} section} /
\MFUsentencecase{\nameref{sec:sentencecase} section}
\end{document}Evaluation
\MFUsentencecase is simply defined as:
\newcommand{\MFUsentencecase}[1]{\text_titlecase_first:n{#1}}
Any change in its behaviour is an issue with \text_titlecase_first:n so I'll have to close this as not a bug in mfirstuc.
\MFUblocker automatically implements \MFUexcl so your MWE without the mfirstuc package is essentially doing:
\documentclass{article}
\usepackage{nameref}
\ExplSyntaxOn
\newcommand{\MFUsentencecase}[1]{\text_titlecase_first:n{#1}}
\newcommand{\MFUexcl}[1]{
\tl_if_empty:nF { #1 }
{
\tl_if_in:NnF \l_text_case_exclude_arg_tl {#1}
{
\tl_put_right:Nn \l_text_case_exclude_arg_tl {#1}
}
}
}
\ExplSyntaxOff
\begin{document}
\section{Sentence-Case}
\label{sec:sentencecase}
\MFUexcl{\nameref}
\MFUsentencecase{\nameref{sec:sentencecase} section}
\end{document}
This does indeed produce "Sentence-Case section" with TeXLive 2024. Replacing \l_text_case_exclude_arg_tl with \l_text_expand_exclude_tl results in the warning:
Reference `Sec:sentencecase' on page 1 undefinedI think you would need to query this with the LaTeX3 team.

Okay, sorry for misunderstanding. I'll add a note to the manual. Thank you for pointing out the problem.

Sorry, I didn't mean to imply this was a problem with the mfirstuc code. I just meant that the manual could be updated so the user reading it isn't confused when their output doesn't match that in the manual (like I was).
I think the change in the kernel titlecase commands happened with this commit: [Link]. There was a brief mention of it in ltnews38: [Link]
