Update 9, The Anti-Copyright Update, is the update that renamed the game from Blox Piece to 
Blox Fruits. The bulk of the work involved renaming islands, fruits, and visual elements to distance itself from One Piece. It also raises the maximum level to 1100 and adds 
Dough, 
Superhuman, the 
True Triple Katana, and 
Snow Mountain.

The Great Rename
The source summarizes the overhaul in one sentence: many visual aspects, content, and names were changed, including the game's name, which went from Blox Piece to Blox Fruits. The stated goal was to resemble One Piece less. The page does not detail the list of islands and fruits affected.
