Apr 1, 2025April 2025 - microsoft/roosterjs monthly summary. Focused on cross-source paste fidelity, codebase modularity, and controlled experimentation of clipboard features. Delivered cross-source paste enhancements for OneNote and Word, improved list handling and introduced a non-list element parser. Refactored GetStyleMetadata to operate independently of DOMCreator by processing HTML strings directly and updated tests. Introduced the Experimental Copy/Cut feature (CustomCopyCut) with pruneUnselectedModel utility and integration into CopyPastePlugin, toggleable via experimental settings. These changes improve content fidelity, reduce user friction, and provide a scalable foundation for future paste/copy improvements.
