Millia can sort of cancel her airdash into a normal? I didn't really get what it does. Can't spot any other new stuff aside from that.
ABA's Danzai now leads to a combo if it counter hits opponents on the ground.
EDIT: It seems that Elphelt can now combo into her bombs super, at least when in the corner. And the bombs stick to her opponent after wallbreak. Not sure if they didn't before, though.
Igorrr. It's very out there but if you don't mind that, it's so so amazing. It's mainly electronic music (mostly breakcore?) + classical instruments + extreme metal and more. Here's a good example. It's off of their amazing album Hallelujah, which I really recommend.
Venetian Snares. A more laid-back version of Igorrr. It's mostly electronic music and classical music. Here's Hajnal, off of their album Rossz Csillag Alatt Született.
