+  - Add currency code SLE/925 to `IsoCurrency` (#89). This currency code was introduced by
+    [ISO-4217 amendment number 171](https://www.currency-iso.org/dam/downloads/dl_currency_iso_amendment_171.pdf) and is

+  >   code SLE/925 representing the new valuation  (1’000 times old SLL/694) is introduced on 1 st April 2022 for any
+  >   internal needs during the redenomination process, and is replacing SLL as the official currency code, after the
+  >   transition period to be determined.
+  >
+  >   During this transition period, both the old Leone and new Leone will be in physical circulation for at least 90
+  >   days.
+  >
+  >   The Bank of Sierra Leone will adopt the new code in the local system but SLL/694 shall remain in use until further
+  >   notice.
+  >
+  >   The Sierra Leonean currency shall continue to be the LEONE and this will not change after redenomination.
