 ## Migration
 
 - Removal of number data without `numberSystem` attributes.
     - Number `<symbols>` elements and format elements (`<currencyFormats>`, `<decimalFormats>`, `<percentFormats>`, `<scientificFormats>`)
 should all have a `numberSystem` attribute. In CLDR v48 such elements without a `numberSystem` attribute will be deprecated, and the
 corresponding entries in root will be removed; these were only intended as a long-ago migration aid. See the relevant sections of the

 ## Known Issues
 
-_No known issues yet._

+  - Non-subdivisions such as `AW`:  Use the region code `AW` instead for translation.
+  - Overlong subdivisions such as `fi01`: Use the region code `AX` instead for translation.
