I've made adjustments to the entire plugin to ensure it works correctly with GLPI 11 (and 10), following the framework's requirements (for example, no direct SQL queries) and full native zero external dependencies . All its features are functional (even bugs present in previous versions may have been fixed), and it's fully translatable (strings) and already updated for all available languages.
Attached is a ready-to-use .zip file and a .docx file with detailed changes.
