During February 2025, H.Y. Acetaminophen focused on enhancing the reliability and scalability of the holzschu/texlive-source repository by addressing two core bugs in TeX engine internals. They standardized error reporting for ignored primitives across euptexdir, pdfTeX, and XeTeX, ensuring consistent diagnostics and maintainability. Additionally, they expanded the eqtb table size in ptex and uptex from 256 to 1024 entries, preventing overflow and supporting larger KINSOKU/INHIBIT configurations. Their work involved C programming, build system updates, and TeX core modifications, with thorough documentation and test artifacts provided to support ongoing development and cross-engine compatibility within the codebase.
