It has now been confirmed that the upgrade was to combine the sword and shielth into a heavier and longer twohander sword, although there may be other hidden features yet to be revealed.

I think the wind effect was probably just a sign of Jaune getting stronger. Although, that doesn't necessarily mean that the whole Dust slot in the pommel theory is out just yet.

The theory of the sword having special or supernatural abilites is stil on the table considering two or three points: 1) The sword could be the same as the King of Vale's sword and maybe have special properties that Jaune simply can't use yet 2) The sword material could be special, and possibly work as a really good conducter for aura/semblances (and Jaune simply can't use it yet due to poor aura control) or be really resiliant and durable 3) Finally the sword could be a vessel for some power, maybe a relic or something and Jaune either lacks the relic or knowledge to use the sword properly

Let it be known that this is merely conjecture based around both the unknown factors of the extent of Crocea Mors upgrade, and the legends about Legendary swords, which tend to follow a trend of being indestructable, never dulling, and generally always cutting down an opponent.

Crocea Mors could also still be a simple swrod and shielth, with the new longsword mode.
