我正在准备一份文件，其中的引文作为脚注，我需要用逗号将它们分开，因此使用了所示问题的答案中建议的代码 文本中连续的 \footcite 命令和分隔逗号。
但是，将 texlive 更新到 2021 版本后，代码不再运行并出现错误。
问题出在这一行：
\AdaptNoteOpt\footcite\multfootcite
我不知道如何修复它，它说未定义的控制序列
删除它后，一切正常，但在安装 texlive 2021 之前它可以正常工作。
我正在使用 lualatex + biblatex
代码如下所示：

All citations appear correctly upon using a cite command on each citation

Citation numbering appear according to the "langid" in reference definition, how to unify output language to a chosen language??

在 MWE 中：https://tex.stackexchange.com/a/123888/231952，只需用 在文档第 7.15 节\AdaptNoteOpt\footcite\multfootcite
中找到的代码替换即可fnpct：
\AdaptNote\footcite{oo+m}[footnote]{%
\setfnpct{dont-mess-around}%
\IfNoValueTF{#1}
{#NOTE{#3}}
{\IfNoValueTF{#2}{#NOTE[#1]{#3}}{#NOTE[#1][#2]{#3}}}%
}

\setfnpct{dont-mess-around}%
\IfNoValueTF{#1}

\printbibliography
\end{document}
\multfootcite您还可以通过以下方式简化定义新命令的语法
\MultVariant{\footcite}
\setfnpct{mult-fn-delim =/}
显然你可以改变mult-fn-delim。要使用默认分隔符（;），只需注释第二行
