It is a sad week for XBMC (soon to be called Kodi) as one of the top addons was pulled by its creator. Mashup is officially dead. Rumor has it that its creator was concerned about possible litigation and was also upset at the amount of people making money off his hard work selling boxes.
Mashup became a favorite for many XBMC users with its all in one design.
Rest In Peace Mashup.
