The locale data based on the Unicode Consortium's CLDR has been upgraded to version 47. Besides the usual addition of new locale data and translation changes, there are notable changes from the upstream CLDR, affecting Date/Time/Number formattings:

   - CLDR-9791: Add language for South Georgia and Bouvet Islands ([#4166](https://github.com/unicode-org/cldr/pull/4166))
   - CLDR-16821: Fix Australian time zone names ([#4301](https://github.com/unicode-org/cldr/pull/4301))
   - CLDR-17484: English day periods are wrong ([#4375](https://github.com/unicode-org/cldr/pull/4375))
   - CLDR-18099: Add European English locales with data ([#4276](https://github.com/unicode-org/cldr/pull/4276), ([#4302](https://github.com/unicode-org/cldr/pull/4302))
   - CLDR-18268: Add timeData for GS ([#4319](https://github.com/unicode-org/cldr/pull/4319))

Note that locale data is subject to change in a future release of the CLDR. Although not all locale data changes affect the JDK, users should not assume stability across releases. For more details, please refer to the [Unicode Consortium's CLDR release notes](https://cldr.unicode.org/index/downloads/cldr-47) and their [locale data deltas](https://unicode.org/cldr/charts/47/delta/index.html).
