Dear list, [I accidentally discovered this issue when validating PDF/A documents with veraPDF.] I have the following sample: \nopdfcompression \setuptagging[state=start] \starttext \startTEXpage[offset=1em] \TeX \stopTEXpage \stoptext The resulting PDF document contains a catalog with the entry "/MarkInfo 17 0 R". If compiled with betas up to 2017.10.15 12:29, the PDF object reads: 17 0 obj << /Marked true >> endobj If compiled with betas starting from 2017.10.19 13:50, the PDF object is empty: 17 0 obj << >> endobj Line 153 in lpdf-tag.lua was changed from its original content in beta 2017.10.15 12:29: Marked = pdfboolean(true), to the new content in beta 2017.10.19 13:50: Marked = lpdf.majorversion == 1 and pdfboolean(true) or nil, I wonder whether this may be related to the LuaTeX version. But this is the newest version from the ConTeXt Suite for the Linux 32bit platform (in beta from 17.10.19 13:50): This is LuajitTeX, Version 1.05.0 (TeX Live 2017) Is this also an issue with more recent LuaTeX versions? Sorry for asking this in the developers’ mailing list, but checking it may be too technical for the standard mailing list. Many thanks for your help, Pablo -- http://www.ousia.tk
