 # Changelog - project.linkedcorp.net
 
+## [4.15.0] - 2026-10-30
+### Added
+- Equipos → detalle: pestaña "Licenciamiento" (antes de Historial) con Windows (edición, Product ID,
+  clave parcial, canal OEM o Retail/Volumen) y Office (licencias que reporta el agente con canal,
+  Product ID y clave parcial; aviso si es MSDN) más el Office instalado. La clave se guarda solo con
+  los últimos 5 caracteres. Los equipos ya inventariados se completan desde su último reporte crudo
+  al abrir el detalle. No indica si la licencia está activada.
+
 ## [4.14.0] - 2026-10-29
 ### Added
 - Equipos → detalle → Hardware: fila "Año del procesador" con botón "Obtener fecha": la IA consulta
