Hello list, Tik-Z files seem to have gone missing in the ConTeXt. Here’s a MWE: \usemodule[tikz] % Error in current MkIV and LMTX, but OK in TeX Live 2021 \usemodule[pgfplots] % Error in Tex Live 2021 \starttext Hello \stoptext The error is in MkIV is: tex error > tex error on line 21 in file /Users/Gavin/context-osx-64/tex/texmf-context/tex/context/modules/mkiv/m-tikz.mkiv: ! I can't find file `t-pgf.tex'. l.21 \input t-pgf.tex The same error in LMTX. The error in Tex Live 2021 is: tex error > tex error on line 48 in file /usr/local/texlive/2021/texmf-dist/tex/generic/pgfplots/pgfplots.code.tex: ! I can't find file `pgflibrarypgfplots.contourlua.code.tex’. l.48 \usepgfplotslibrary{contourlua} Maybe I’m doing a poor job of maintaining my installations, but maybe this is a problem with the download. Thanks! Gavin
