Aug 1, 2025In August 2025, delivered a critical bug fix in LimeSurvey/LimeSurvey to ensure robust survey token persistence and proper association with responses during active participant sessions. Implemented session-scoped token storage when missing, ensured tokens are correctly assigned to responses, and added a guard to verify token attributes exist before persisting. This work reduces write-time errors and improves data integrity for token-based participation flows, aligning with LE-279 and related fixes.

Jul 1, 2025In July 2025, delivered a data-integrity enhancement for LimeSurvey/LimeSurvey: a fully automated Survey Last Modified Date Tracking feature. The change introduces a last_modified field on surveys and a set of triggers across related tables (answers, groups, questions, language settings) to auto-update the timestamp on inserts, updates, or deletes. A new TriggersManager coordinates the application of these triggers during initial database installation, ensuring data consistency from deployment and displaying up-to-date last modified dates in the survey list.
