Yes, the've changed the jump.

Q31:
Is it a bug that we can change our direction during Jump? Is this going to get fixed? I believe there's various opinions regarding this one, but I personally am enjoying this, so would like this to be untouched.

A31:
Dragoons can currently change their direction during Jump. If this becomes a sort of necessary technique, we may have to disable this on dragoon’s Jump actions. The normal jump won’t be changed.
