DSM-IV stated that the symptoms of major depressive disorder must not be attributable to normal bereavement. What did DSM-5 do with that rule?

1. DSM-IV carried a bereavement exclusion that kept normal grief outside the diagnosis of major depressive disorder. 2. DSM-5 removed that exclusion, so grief and sadness following the death of a loved one can constitute major depressive disorder. 3. This change is one of the grounds on which critics argue the criteria have been loosened too far. 4. The rule was not extended, shortened or relocated, and persistent depressive disorder carries its own separate criteria. 5. The trap is assuming a controversial rule must have been tightened when in fact it was dropped. _Source: OpenStax Psychology (1st ed., CC BY 4.0), Ch 15 "Psychological Disorders", section 15.2 Diagnosing and Classifying Psychological Disorders_
