35014	update_or_create using update_fields  opt out	Jordan Hyatt	nobody	Prior to 4.2 update_or_create method did not use update_fields.  That means developer's could count on the model save method being run and all fields being updated regardless of the defaults argument.   After 4.2 only those fields passed to default will be updated.  This presents a major breaking change especially for developers who rely heavily on save methods to populate fields.  I believe there should be a parameter added to update_or_create that allows the user to opt out of using update_fields during save.
