Sep 1, 2025September 2025 monthly summary for chamilo/chamilo-lms focusing on key features, bug fixes, and impact across the platform. What was delivered: - Global localization and translations: FR translations for Session admins, Vue translation updates, and an added missing FR translation to ensure consistent UI in French across Session admin workflows. Also fixed translation variables and German FR terms to improve localization fidelity. - Robust input handling and API contract fixes: prevented errors when reply_to name or email is missing and standardized parameter naming to email, aligning with API expectations. - Stability fixes for user workflows: restored session ticket functionality via session announcement revert fix; fixed date handling for quiz expiration; and corrected closing parentheses in quiz code to prevent runtime/parse errors. - Consistency and maintenance improvements: adjusted migration order safety, refined profile configuration by removing dev indicator, and addressed translation-related edge cases to reduce future regressions. Impact: - Reduced error surface in session tickets and messaging flows; improved localization accuracy for French and German users; and enhanced stability for quizzes and form handling. These changes support a smoother user experience, lower support load, and clearer data contracts for API consumers. Technologies/skills demonstrated: - PHP backend fixes and code hygiene - Vue.js-based translations and localization workflows - Internationalization (i18n) and translation variable management - Data integrity and input validation - Migration safety and deployment hygiene

Feb 1, 2025February 2025: Implemented a robust inactive-user handling fix for Chamilo LMS cron. Added a fallback to use the user creation date when no login record exists to correctly identify and process inactive users, addressing an edge case in Chamilo 2 prior to 2025/12/01. The change reduces cron errors and improves data integrity for user lifecycle processing, with clear traceability to BT#21933.
