Model.objects.filter(mycharfield=None) ''used to'' return instances where mycharfield is actually a zero-length string. Now, it seems I need to explicitly specify Model.objects.filter(mycharfield=''). Minor change, but the implications could be pretty severe for some apps. Suggest either reverting to previous behaviour or updating the ""backwards incompatible changes"" list." Uncategorized closed Documentation 1.5 Normal needsinfo andrewsg Unreviewed 0 0 0 0 1 0
