May 1, 2025May 2025 (ckeditor/ckeditor5) delivered measurable business value through UI polish, data-attribute support, and improved developer tooling. Key improvements include fullscreen mode UI/UX stabilization with CSS/layout refinements and test coverage alignment; robust support for data-list-item-id attributes with conversions/upcasting and a stability flag that yields deterministic test outputs; and a development tooling fix to ensure local setup and testing reliability. These efforts reduce UI regressions, improve automated test stability, and streamline future feature work.
