During July 2025, K42s enhanced the DivinumOfficium/divinum-officium repository by modernizing its deployment infrastructure and refining EPUB generation logic. They updated the Dockerfile to use the latest Debian release, addressing security and compatibility concerns associated with end-of-life distributions. In addition, K42s improved the epubgen2 shell script to ensure the language option correctly controlled the right-side display, clarifying user-facing behavior. Their work focused on DevOps and scripting, emphasizing maintainability and long-term support. While no bugs were reported as fixed, the changes provided a safer deployment baseline and clearer EPUB language handling, demonstrating thoughtful, targeted improvements within a short timeframe.
