When did pervasive developmental disorders become part of "autism spectrum disorders"?

ANSWER

The name change came in 2013, when the American Psychiatric Association reclassified autistic disorder, Asperger’s syndrome, childhood disintegrative disorder, and pervasive developmental disorder not otherwise specified (PDD-NOS) as autism spectrum disorders.

Why the change? The spectrum concept is a more medically accurate way of diagnosing children with these disorders.
