Release Notes

oschwald/geoip2-golang (github.com/oschwald/geoip2-golang)

v2.0.1: 2.0.1

Compare Source

• Upgraded github.com/oschwald/geoip2-golang/v2 to 2.1.1, which fixes an
  issue that prevented a unclosed memory-mapped file from being unmapped
  when the reader was garbage collected.

v2.0.0: 2.0.0

Compare Source

• BREAKING CHANGE: Lookup methods now require netip.Addr, return typed
  Names, and provide HasData() helpers while always populating
  Network/IPAddress fields so network topology remains accessible.
• BREAKING CHANGE: Struct field casing now matches MaxMind responses (for
  example IsoCode → ISOCode), location coordinates use pointers, and JSON
  tags rely on Go 1.24 omitzero support—upgrade your toolchain before
  adopting v2.
• BREAKING CHANGE: Removed FromBytes method. Use OpenBytes instead.
• Added MIGRATION.md with detailed guidance for upgrading from v1.
• Updated dependency on github.com/oschwald/maxminddb-golang/v2 to v2.0.0.
• Added configurable Option helpers so Open and OpenBytes can accept
  future options without forcing a v3 release.
