Oct 1, 2025October 2025: Delivered a front-end enhancement for CollaboraOnline/online focused on comment navigation. Implemented Comment Scrollability and Dynamic Expansion to ensure long comment threads are fully accessible with accurate scroll area calculations. Added a mechanism to determine the size of the last commit prior to scroll calculation to guarantee visibility of all comments. Fixed a regression in last-comment visibility to prevent the final comment from being hidden.

Feb 1, 2025February 2025 (CollaboraOnline/online): Implemented telemetry enhancements for document load/save operations and fixed telemetry data quality issues. This included granular logging for save, savebg, saveas, and exportas (duration, file size, extension) and updated statistics to support richer visualization. Fixed mislogging of application-initiated opens by assigning userID -1 and excluding sessions with userID 1; extended load/save metrics to include file sizes and median times by file type. Impact: improved data accuracy, better data-driven decisions, and a solid foundation for dashboards and BI.
