This updated brings:  

1.a whole new line for palmon. 

2.Day and night cycles. after 18:00 night starts, after 6am the day starts. 

3.Various new battle backgrounds. 

The mood and discipline are more flexible, the digimon will get happy and sad more easily, the same for discipline. Losing/winning battles will influence it much more than before. Praising and scolding too.
