20118	Upgrade from Django 1.4 to 1.5 creates South migration	Ram Rachum	nobody	"I noticed that South suddenly wants to create a new schema migration. I'm guessing that this is due to my upgrade from Django 1.4 to Django 1.5.

The migrations added `on_delete=models.SET_NULL`, I believe.

I suggest that this become part of the upgrade guide. Better have South create and apply those migrations as quickly as possible after the upgrade, instead of discovering it some time afterwards."	Bug	closed	Documentation	1.5	Normal	needsinfo			Accepted	0	0	0	0	0	0
