For 2025-08, RoosterJS delivered developer-focused markdown improvements with a strong emphasis on correctness, maintainability, and editor fidelity. Key features include Strikethrough Markdown Support and Spacing Fix, enabling proper handling of the ~~ syntax and reliable bidirectional conversion between Markdown and the content model. In addition, Advanced Markdown Formatting and Parsing Enhancements improve nested formatting (bold, italic, strikethrough), marker handling, and trailing-space treatment, backed by refactors and expanded tests to ensure correctness across complex scenarios. These changes reduce rendering and content-model discrepancies in real-world editors and prepare the codebase for more advanced markdown features. Business value: more accurate, reliable Markdown support in RoosterJS-based editors, fewer regressions, and faster iteration for feature work and bug fixes. Technical impact includes improved parser robustness, safer refactors (move from let to const), removal of noisy log statements, and better test coverage for edge cases.
