7690	obj.manytomanyrel = None no longer works, needs reference in BackwardsIncompatibleChanges	dnordberg	nobody	"It used to be that a manytomany relationship could be assigned to None, which would be the same as calling clear(). 

E.g. {{{obj.manytomanyrel = None}}} was the same as {{{obj.manytomanyrel.clear()}}}.

I think this was also in the documentation.

Now I cant do {{{obj.manytomanyrel = None}}}. I can however do this, {{{obj.manytomanyrel = []}}}.

I think needs to be added to db-api and BackwardsIncompatibleChanges."		closed	Documentation	dev		wontfix			Unreviewed	0	0	0	0	0	0
