 ## Unreleased
 
+### Align jsx runtime for optimized dependencies
+
+This will only affect people using internal libraries that contains untranspiled JSX. This change aligns the optimizer with the source code and avoid issues when the published source don't have `React` in the scope.
+
+Reminder: While being partially supported in Vite, publishing TS & JSX outside of internal libraries is highly discouraged.
