5.2.0

• A new residential field has been added to the Anonymizer record. This
  is an AnonymizerFeed record containing confidence, networkLastSeen,
  and providerName fields with residential proxy data for the network.
  residential may be populated even when none of the other fields on
  Anonymizer are set. The AnonymizerFeed record is intended to be reused
  for additional feeds, such as VPNs, mobile networks, and hosting or
  datacenter providers, that may be added in the future.
