0.2.0 - 2026-06-23

Added

• Three new identifier types, implemented clean-room from their public standards (no third-party port; stays EPL):
  • :lei - Legal Entity Identifier (ISO 17442, ISO 7064 mod-97-10).
  • :br-cpf - Brazil individual taxpayer registry, with format.
  • :br-cnpj - Brazil company registry, with format.
• compact/format now also strip / (used by the CNPJ written form).

Country-specific identifiers are keyed by an ISO-3166 prefix (e.g. :br-cpf).

0.1.0 - 2026-06-23

Initial release.

Added

• stdnum.core - a unified facade for validating, parsing, and formatting standard identifier numbers, dispatched on a type keyword:
  • valid?, parse, format, compact, detect, card-network, and the types set.
  • Identifier types: :credit-card (with network detection), :iban, :bic, :isbn, :issn, :isin, :aba (US bank routing), :imei, :luhn.
• Idiomatic facade over Apache Commons Validator 1.10.1 and iban4j 3.2.11 - no algorithm reimplementation. Bad input data never throws; only an unknown identifier type does.
