5.4.1

• First release via Trusted Publishing.

5.4.0

• .NET 10.0 has been added as a target.
• A new Anonymizer object has been added to InsightsResponse. This object
  provides anonymizer-related data including VPN confidence scoring, provider
  name detection, and network last seen date. This data is available from the
  GeoIP2 Insights web service.
• A new IpRiskSnapshot property has been added to MaxMind.GeoIP2.Model.Traits.
  This provides a risk score associated with the IP address, ranging from 0.01
  to 99. Higher scores indicate greater risk. This is available from the GeoIP2
  Insights web service.
• The following properties in MaxMind.GeoIP2.Model.Traits have been marked
  Obsolete and users should migrate to using the Anonymizer object on the
  response instead: IsAnonymous, IsAnonymousVpn, IsHostingProvider,
  IsPublicProxy, IsResidentialProxy, and IsTorExitNode. These properties
  will continue to work but are deprecated in favor of the new Anonymizer
  object.
• A new MaxMind.GeoIP2.Model.Anonymizer class has been added with the
  following properties:
  • Confidence - A score ranging from 1 to 99 representing percent confidence
    that the network is currently part of an actively used VPN service.
  • IsAnonymous - Indicates whether the IP belongs to any sort of anonymous
    network.
  • IsAnonymousVpn - True if the IP is registered to an anonymous VPN provider.
  • IsHostingProvider - True if the IP belongs to a hosting or VPN provider.
  • IsPublicProxy - True if the IP belongs to a public proxy.
  • IsResidentialProxy - True if the IP is on a suspected anonymizing network
    and belongs to a residential ISP.
  • IsTorExitNode - True if the IP belongs to a Tor exit node.
  • NetworkLastSeen - The last day the network was sighted in analysis of
    anonymized networks (available on .NET 6.0+ as DateOnly).
  • ProviderName - The name of the VPN provider associated with the network.
