Capcom has finally released a full list of changes coming via the Super Street Fighter IV Arcade Edition 'Ver. 2012' update. It's monster.
It details move tweaks and balance changes for every character, with anywhere from two to 20 changes per character.
Unfortunately it's so large we couldn't post it all tidily below. But this is a direct link to the English version of the PDF Capcom has carefully crafted for your viewing convenience.
'Ver. 2012' is a free update coming soon, as announced at the EVO 2011 Fighting Tournament earlier this year.
