Mar 1, 2026March 2026 monthly summary for chamilo/chamilo-lms: Delivered three key features across security, access control, and deprecation to strengthen security, improve UX, and simplify maintenance. AICC support was deprecated and removed to eliminate legacy dependencies and reduce risk. Social Post Attachments were hardened by restricting to images/videos and sanitizing SVG to prevent XSS. CardGame access rendering was optimized by rendering only for authenticated users in the correct route contexts, and initialization cleanup logic was trimmed to improve startup performance. These changes reduce attack surface, streamline code paths, and improve user experience across the LMS.
