• international-street-api
  • Breaking: Lookup.Language changed from string to LanguageMode?, now a real enum with Native and Latin members. Replace string literals with enum members, or use LanguageModeExtensions.FromValue() to resolve a raw string case-insensitively (e.g. "Latin", "NATIVE").

• international-street-api
  • Breaking: lookup.language is now the LanguageMode enum (LanguageMode.Native, LanguageMode.Latin) instead of an open string type. Raw strings are resolved case-insensitively via the new resolveLanguageMode().
  • Breaking: Client.send() now validates the lookup before sending, so invalid language and geocode values (previously never checked) throw UnprocessableEntityError.
• Bumped optional dependency undici from 7.27.2 to 7.29.0.

• international-street-api
  • Breaking: LanguageMode is now a backed enum (LanguageMode::Native, LanguageMode::Latin) instead of a string-wrapping class, so invalid values can no longer be constructed. Use LanguageMode::fromValue() to resolve a raw string case-insensitively; it throws UnprocessableEntityException for invalid values.

• international-street-api
  • Breaking: LanguageMode is now an Enum (LanguageMode.NATIVE, LanguageMode.LATIN) instead of module-level string constants. Lookup.language is validated and normalized case-insensitively at send time; invalid values raise UnprocessableEntityError. Use LanguageMode.from_value() to resolve a raw string.

• international-street-api
  • Breaking: LanguageMode is now a closed set of Data-backed instances (LanguageMode::NATIVE, LanguageMode::LATIN) instead of plain string constants. Lookup#language is validated and normalized case-insensitively at send time; invalid values raise SmartyStreets::UnprocessableEntityError. Use LanguageMode.from_value() to resolve a raw string.
