 # `@react-router/dev`
 
+## 7.9.6-pre.0
+
+### Patch Changes
+
+- Use a dynamic `import()` to load ESM-only `p-map` dependency to avoid issues on Node 20.18 and below ([#14492](https://github.com/remix-run/react-router/pull/14492))
+- Short circuit `HEAD` document requests before calling `renderToPipeableStream` in the default `entry.server.tsx` to more closely align with the [spec](https://httpwg.org/specs/rfc9110.html#HEAD) ([#14488](https://github.com/remix-run/react-router/pull/14488))
+- Updated dependencies:
+  - `react-router@7.9.6-pre.0`
+  - `@react-router/node@7.9.6-pre.0`
+  - `@react-router/serve@7.9.6-pre.0`

 # `react-router`
 
+## 7.9.6-pre.0
+
+### Patch Changes
+
+- [UNSTABLE] Add `location`/`params` as arguments to client-side `unstable_onError` to permit enhanced error reporting. ([#14509](https://github.com/remix-run/react-router/pull/14509))
+
+  ⚠️ This is a breaking change if you've already adopted `unstable_onError`. The second `errorInfo` parameter is now an object with `location` and `params`:
+
+  ```tsx
+  // Before
+  function errorHandler(error: unknown, errorInfo?: React.errorInfo) {
+    /*...*/
+  }
+
+  // After
+  function errorHandler(
+    error: unknown,
+    info: {
+      location: Location;
+      params: Params;
+      errorInfo?: React.ErrorInfo;
+    },
+  ) {
+    /*...*/
+  }
+  ```
+
+- Properly handle ancestor thrown middleware errors before `next()` on fetcher submissions ([#14517](https://github.com/remix-run/react-router/pull/14517))
+- Fix issue with splat routes interfering with multiple calls to patchRoutesOnNavigation ([#14487](https://github.com/remix-run/react-router/pull/14487))
