The release notes for Safari 15.4 mention that Intl.NumberFormat.formatRange(), Intl.NumberFormat.formatRangeToParts(), and Intl.PluralRules.selectRange() have all been added. https://developer.apple.com/documentation/safari-release-notes/safari-15_4-release-notes However, doing some simple tests, all of the functions above are undefined new Intl.NumberFormat('de-DE').formatRange; // undefined new Intl.NumberFormat('de-DE').formatRangeToParts; // undefined new Intl.PluralRules('de-DE').selectRange; // undefined I've tested the other Intl features added in 15.4 but every other feature except these three seem to be implemented correctly

Thanks. This needs the latest macOS / iOS update too since it relies on the system-installed ICU. So, please update the OS to update the system ICU.
