hello to all the users I want to know when to launch some newfirmware for the Sansa Fuze plus apart from the other vesion2.36.03 version that can further improve the system plus Sansa Fuze

The latest firmware was released about 3 weeks ago. The normal schedule for actively supported players is a new firmware every 3 months , so realistically you shouldn’t expect another one for more than two months. (Occasionally they’ll issue a new one more quickly, but don’t count on it.)
