+'@clerk/localizations': patch
+---
+
+The package now allows for [subpath exports](https://nodejs.org/api/packages.html#subpath-exports).
+
+```diff
+- import { frFR } from "@clerk/localizations"
++ import { frFR } from "@clerk/localizations/fr-FR"
+```
+
+This should help with tree-shaking by helping the bundler to include only specific localization.
+
+This is a non-breaking change-previous imports from "@clerk/localizations" are still working as expected.
