-Starting from v10, Legacy API mode can use the same `$t` overload signature as Composition API mode.
-
-**Reason**: After that migration, when migrating to Composition API mode, we sometimes fall into a pitfall due to the different signature of `$t`.

+Starting from v10, Legacy API mode can use the same `$t` and `t` overload signature as Composition API mode.
+
+**Reason**: After that migration, when migrating to Composition API mode, we sometimes fall into a pitfall due to the different signature.
 
 If you are using the following APIs in Legacy API mode, you must change to another signature because of the breaking changes:
 
-- `$t(key: Path, locale: Locale): TranslateResult;`
-- `$t(key: Path, locale: Locale, list: unknown[]): TranslateResult;`
-- `$t(key: Path, locale: Locale, named: NamedValue): TranslateResult;`
