During July 2025, Michal Cepl focused on maintaining and improving the documentation and code health of the libsdl-org/highway repository. He addressed the long-term accessibility of the Design Philosophy documentation by replacing deprecated goo.gl shortened URLs with canonical links, ensuring future-proof references for contributors. Using C++ and Markdown, Michal also fixed a broken hyperlink to a PDF, restoring access to essential reference material. His work included targeted typo corrections and documentation cleanups, enhancing clarity and usability for future maintainers. While no new features were introduced, his efforts contributed to the repository’s sustainability through diligent code maintenance and documentation improvements.
