The locale data based on the Unicode Consortium's CLDR has been upgraded to version 46. Besides the usual addition of new locale data and translation changes, there are notable changes from the upstream CLDR, affecting Date/Time/Number formattings:

- First day of week is Monday in UAE [CLDR-15697](https://unicode-org.atlassian.net/browse/CLDR-15697)
- Default numbering system for Arabic in non-Arabic-speaking locations [CLDR-17553](https://unicode-org.atlassian.net/browse/CLDR-17553)
- Comma is added for some date formatting patterns [CLDR-17812](https://unicode-org.atlassian.net/browse/CLDR-17812) -
- Some time zone names changed due to them becoming links to other zones [CLDR-17960](https://unicode-org.atlassian.net/browse/CLDR-17960)

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-46) and their [locale data deltas](https://unicode.org/cldr/charts/46/delta/index.html).
