• Support for mobile country code (MCC) and mobile network codes (MNC) was
  added for the GeoIP2 ISP and Enterprise databases as well as the GeoIP2
  City and Insights web services. getMobileCountryCode() and
  getMobileNetworkCode() were added to com.maxmind.geoip2.model.IspResponse
  for the GeoIP2 ISP database and com.maxmind.geoip2.record.Traits for the
  Enterprise database and the GeoIP2 City and Insights web services. We expect
  this data to be available by late January, 2022.
• Deprecated model constructors that exist for backwards compatibility.
  These constructors are not generally used by users of this library
  directly except perhaps when mocking the reader in tests.
