ISO Currency Changes 2025 #428
Description
We need to add the following ISO4217 changes to the schemas (consult https://en.wikipedia.org/wiki/ISO_4217 for details):
- CUC (Cuban Convertible Peso) redenominated to CUP in 2021
- SLL (Siera Leoneon Leone) redenominated to SLE in 2022
- HRK (Croatian Kuna) replaced by EUR in 2023
- ZWL (Zimbabwean Dollar - 4th/5th) redenominated to ZWG in 2024
- ANG (Dutch Angolan Guilder) redenominated to XCG in 2025
Suggest doing it in two stages:
- Add new codes (CUP, SLE, ZWG, XCG) and notify of deprecated currencies (feat: add new iso4217 currencies #429)
- Remove CUC, SLL, HRK, ZWL, ANG at a later date (refactor: remove legacy iso currency codes #430)
