+## [4.0.1]
+
+This release contains bugfixes and ehancements and is recommended for all users of Helidon 4.
+
+Java 21 is required to use Helidon 4.0.1.
+
+### Notable Changes
+
+- Added PROXY protocol support to Helidon WebServer
+- WebServer performance improvements
+- `CorsConfig.Builder.enabled()` now returns an `Optional<Boolean>` instead of `boolean`. This change was required to fix a CORS issue and we expect the user impact of this change to be minimal.
