+  Recursor passthrough removal: This will impact many installations.
+  Previously, the PowerDNS Authoritative Server contained a facility
+  for sending recursion desired queries to a resolving backend,
+  possibly after first consulting its local cache. This feature
+  (‘recursor=’) was frequently confusing and also delivered
+  inconsistent results, for example when a query ended up referring
+  to a CNAME that was outside of the Authoritative Server’s
+  knowledge.
