Dear all, I get this error with context from current version: 2024.11.01 19:19 1 >> \environment env-alegreya 2 \environment env-alegreya-trimsize5-8 3 \environment env-deutsch 4 \environment env-makeups 5 \environment env-umbruch 6 \environment env-heading-sans 7 \environment env-layout 8 \environment env-figures 9 \environment env-pandoc 10 \setupcaptions[number=yes] 11 \setupdocument [ A number should have been here; I inserted '0'. (If you can't figure out why I needed to see a number, look up 'weird error' in the index to The TeXbook.) No problems with this versions: current version: 2023.02.07 19:06 current version: 2024.04.01 08:59 Were there changes how we have to treat environment files? The error only occurs when I use "--mode=trimsize" but I cannot track down the error by removing environments with mode-specific definitions. The first environment file does not contain any mode-specific definitions. Any hints? TIA juh
