Hi, We use PDF tools like mutool, pdfinfo (from poppler) and exiftool in our workflow (once the PDFs are created by ConTeXt). But looks like we have hit upon some regression issue between 1.0.3 and 1.0.4 versions. Both pdfinfo (from poppler) and exiftool are able to read PDFs created from 1.0.3 but have trouble reading PDFs created with 1.0.4. Please see below logs for details. Our 1.0.4 is from April-2021. We will try to upgrade to the latest 1.0.4 and try again. mtx-context | ConTeXt Process Management 1.04 mtx-context | mtx-context | main context file: /ConTeXt/apr2021/tex/texmf-context/tex/context/base/mkiv/context.mkiv mtx-context | current version: 2021.04.21 11:39 mtx-context | main context file: /ConTeXt/apr2021/tex/texmf-context/tex/context/base/mkxl/context.mkxl mtx-context | current version: 2021.04.21 11:39 mtx-context | ConTeXt Process Management 1.03 mtx-context | mtx-context | main context file: /ConTeXt/sep2020/tex/texmf-context/tex/context/base/mkiv/context.mkiv mtx-context | current version: 2020.09.20 23:02 mtx-context | main context file: /ConTeXt/sep2020/tex/texmf-context/tex/context/base/mkiv/context.mkxl mtx-context | current version: 2020.09.20 23:02 *====pdfinfo (from Poppler)====* ~/TeX$ pdfinfo Hello-world_1.0.4.pdf Syntax Error: Missing 'endstream' or incorrect stream length Syntax Error: Missing 'endstream' or incorrect stream length Title: Hello world!
