 # @solidjs/router
 
+## 2.0.0-next.23
+
+### Patch Changes
+
+- 12a2500: Accept an explicit `undefined` on every optional `RouteDefinition` property (and on the optional properties of `defineRoute`, `defineFileRoute`, and their returned config types), so route trees produced under `exactOptionalPropertyTypes` — notably `fileRoutes()` applied to `filesystem-routing`'s generated manifest types, whose leaves carry `children: undefined` — type-check. The runtime already treated absent and `undefined` alike; the one presence check (`hasOwnProperty("path")`) now treats an explicit `path: undefined` as a pathless route too (#598).
