在 2018-2019 年，的语法\chemfig发生了两次变化。最近一次发生在 2019 年 2 月，v1.4（参见CTAN 上 v1.4 的公告文本）。现在\chemfig只接受一个可选参数，如\chemfig[<key-value option list>]{<molecule code>}。
从相关的源代码更改，旧语法
\chemfig[][scale=0.8]{...}
相当于设置
every node/.style={scale=0.8}
用新语法来说，可以通过以下方式实现
\chemfig[atom style={scale=0.8}]{...}
在下面的例子中，我定义了一个新chemfig选项scale，其作用与旧scale选项相同。
\documentclass{article}
\usepackage{chemfig}
\ExplSyntaxOn % not equivalent to what "chemfig.tex" does, but suffient
\makeatletter
\defKV[chemfig]{
scale = \g@addto@macro\CF_atomstyle{scale=#1}
}
\makeatother
\ExplSyntaxOff
\begin{document}
\begin{tabular}{rl}
Normal size:
& \chemfig{CH_3CH_2CH_2-CHO} \\
New syntax with \verb|atom style|:
& \chemfig[atom style={scale=0.8}]{CH_3CH_2CH_2-CHO} \\
New syntax with new option \verb|scale|:
& \chemfig[scale=0.8]{CH_3CH_2CH_2-CHO}
\end{tabular}
\end{document}
