I prefere meld :-) TeXLive2019: ------------ \def\input{\@ifnextchar\bgroup\@iinput\@@input} \def\@iinput#1{% \InputIfFileExists{#1}{}% {\filename@parse\@curr@file \edef\reserved@a{\noexpand\@missingfileerror {\filename@area\filename@base}% {\ifx\filename@ext\relax tex\else\filename@ext\fi}}% \reserved@a}} TeXLive2022: ------------ \def\input{\@ifnextchar\bgroup\@iinput\@@input} \def\@iinput#1{% \InputIfFileExists{#1}{}% {\filename@parse\@curr@file \edef\reserved@a{\noexpand\@missingfileerror {\filename@area\filename@base}% {\ifx\filename@ext\relax tex\else\filename@ext\fi}}% \reserved@a \edef\reserved@a{\noexpand\@iinput{% \@missingfile@area\@[log in to unmask]\@missingfile@ext}}% \reserved@a}} I didn't see any other difference.
