True question out of ignorance, but what retcons have been implemented to Batman? Are any of them major? Off the top of my head, I know his use of guns were retconned (I mean, does Golden/Silver Age really count anyway?). I believe when/how he met Gordon and also Gordon knowing his identity has been changed throughout history? Maybe his relationships w/ women? Are all of these sorta...inconsequential? Has he ever had anything retconned to the level of his parents not dying or what motivated him to become Batman, etc?
