I found a change for all characters!!
This was performed randomly on Falco, Mario, and Marth. So you know how when you run off stage your character is falling with a flipping animation? In previous versions, that animation happened only if the character finished performing their initial dash before falling off.
In 1.0.6, your character will do the flipping animation even if your initial dash wasn't complete. A perfect character to try this on between versions is Marth because he has a very long initial dash (for those of you who don't know, an initial dash is the beginning part of your dash that you can't cancel with shield). Conclusion: standing at the ledge and running off will now do the special animation no matter how far you are from the ledge.
Will this affect anything? Since the animation can be canceled whenever, it won't. But it's still something that changed.
