-Nodes can't be directly exported. Instead you need to export
-a node path, then use that node path with `get_node()`
+Since Godot 4.0, nodes can be directly exported as properties in a script
+without having to use NodePaths:
+
+::
+
+    # Allows any node.
+    @export var node: Node
+
+    # Allows any node that inherits from BaseButton.
+    # Custom classes declared with `class_name` can also be used.
+    @export var some_button: BaseButton
+
+Exporting NodePaths like in Godot 3.x is still possible, in case you need it:
 
 ::
 
     @export var node_path: NodePath
     var node = get_node(node_path)
 
-If you want to limit the types of nodes, you can use the @export_node_path annotation.
