+
+We have added an [`anonymizer` object](https://dev.maxmind.com/geoip/docs/web-services/responses/#anonymizer) to our web services. This object contains the anonymizer data previously found in the `traits` object together with new outputs.
+
+Anonymizer data in the `traits` object is being marked as deprecated. However, for backwards compatibility, anonymizer data in the `traits` object will continue to be populated and the functionality remains the same. This will not be a breaking change. 
+
+We recommend updating your integrations if you wish to use the new `anonymizer` object, which contains data points not found in the `traits` object:
+
+| new data | description |
+| -------------------------------- | -------------------------------- |
+| confidence                       | A score ranging from 1 to 99 that represents our percent confidence that the network is currently part of an actively used VPN service.| 
+| network_last_seen                | The last day that the network was sighted in our analysis of anonymized networks. This is in the ISO 8601 date format (YYYY-MM-DD). |
+| provider_name                  | The name of the VPN provider (e.g., NordVPN, SurfShark, etc.) associated with the network. |
+
+We plan to update the client APIs soon to reflect this change, which applies to the following web services: 
+- GeoIP Insights
+- minFraud Insights
+- minFraud Factors
