Locale data based on the Unicode Consortium's CLDR has been upgraded to version 43. The JDK locale data now employs [`coverageLevels.txt`](https://cldr.unicode.org/index/cldr-spec/coverage-levels ), including the 'basic' and above level locale data, in addition to the data already existing in prior JDK releases for compatibility. For detailed locale data changes, please refer to the [Unicode Consortium's CLDR release notes](https://cldr.unicode.org/index/downloads/cldr-43).
