Nov 1, 2025November 2025: Focused on securing and stabilizing Markdown/MDX rendering in readmeio/markdown. Delivered safe rendering by stripping HTML comments and robust handling of legacy magic blocks, ensuring large HTML blocks no longer disrupt parsing. Implemented a reusable stripComments library and a transformer to operate on both MD and MDX, with a placeholder-based approach to preserve magic blocks during parsing. This reduces security exposure, improves rendering reliability across projects, and enhances cross-team consistency in documentation rendering.

May 1, 2025May 2025 – Readmeio/markdown: compatibility and security enhancements with a focus on emoji parity, API compatibility, and safe HTML rendering. Re-exported Owlmoji to align with legacy package, expanded emoji catalog (owlbert set), removed a sorting regression, and added unit tests. Implemented HTML sanitization for Markdown rendering using rehypeRaw and rehypeSanitize, with tests for safe and unsafe HTML. These changes improve integration reliability for consumer apps, reduce security risk, and expand test coverage for future resilience.
