I used to use the acro package for managing my acronyms and I also used acronyms in my bibliography which I compile with biblatex/biber. After updating MikTeX packages this doesn't work anymore. Here is my minimal example:
\RequirePackage{filecontents}
\begin{filecontents}{\jobname-bib.bib}
@Book{TEST,
author = {{\acs{ISO} X}},
title = {You name it},
year = {2015},
}
\end{filecontents}
\documentclass{scrbook}
\usepackage[backend=biber]{biblatex}
\usepackage[printonlyused]{acronym}
\usepackage{zref,
xkeyval,
ifpdf,
ifthen,
calc,
marginnote,
datetime2,
refcount,
soulpos}%suggested to use with acronym
\addbibresource{\jobname-bib.bib}
\begin{document}
\begin{acronym}
\acro{ISO}{International Organization for Standardization}
\end{acronym}
This is text and I want to cite with acronyms: \cite{TEST}
\printbibliography
\end{document}
Compiling ends with:
! Extra }, or forgotten \endgroup.
l.27 }
?
acronympackage in your example not theacropackage (although possibly a similar problem occurs withacro). – Nicola Talbot Mar 13 '18 at 22:15
