We are updating the IATI Currency Codelist to bring it in line with changes to the ISO 4217 Currency codelist: http://www.iso.org/iso/home/standards/currency_codes.htm
Notable changes are:
BYR - Belarussian Ruble code is now: BYN
MRO - Ouguiya code is now: MRU
STD - Dobra code is now: STN
ZMK - Zambian Kwacha is now: ZMW
As these are breaking changes we are marking the old codes as ‘withdrawn’ and seperately adding in the new codes.
