• The web service client API has been updated for the v2.1 release of the web
  service. In particular, the city_isp_org and omni methods on
  geoip2.webservice.Client should be considered deprecated. The city
  method now provides all of the data formerly provided by city_isp_org,
  and the omni method has been replaced by the insights method.
  Note: In v2.1 of the web service, accuracy_radius,
  autonomous_system_number, and all of the confidence values were
  changed from unicode to integers. This may affect how you use these values
  from this API.
• Support was added for the GeoIP2 Connection Type, Domain, and ISP databases.
