March 2025 performance highlights. Key features delivered in the Rich Text Editor include enhanced image paste handling with robust image selection, allowed image type filtering, and centralization of image persistence in the editor context. Release-related work stabilized builds (versions 8.2.5-0 and 8.3.0) through version bumps and lockfile adjustments. The Exam Engine was updated to use RTE 8.3.0 to enable improved editing experiences. Testing and documentation improvements for paste scenarios, plus snapshot updates to reflect UI changes, reinforced test reliability. Overall impact: more reliable content authoring, cleaner maintenance, and more stable release cadence.
