 # react-router-dom
 
+## 6.4.0-pre.15
+
+### Patch Changes
+
+- fix: remove internal router singleton (#9227)
+
+  This change removes the internal module-level `routerSingleton` we create and maintain inside our data routers since it was causing a number of headaches for non-simple use cases:
+
+  - Unit tests are a pain because you need to find a way to reset the singleton in-between tests
+    - Use use a `_resetModuleScope` singleton for our tests
+    - ...but this isn't exposed to users who may want to do their own tests around our router
+  - The JSX children `<Route>` objects cause non-intuitive behavior based on idiomatic react expectations
+    - Conditional runtime `<Route>`'s won't get picked up
+    - Adding new `<Route>`'s during local dev won't get picked up during HMR
+    - Using external state in your elements doesn't work as one might expect (see #9225)
+
+  Instead, we are going to lift the singleton out into user-land, so that they create the router singleton and manage it outside the react tree - which is what react 18 is encouraging with `useSyncExternalStore` anyways! This also means that since users create the router - there's no longer any difference in the rendering aspect for memory/browser/hash routers (which only impacts router/history creation) - so we can get rid of those and trim to a simple `RouterProvider`
+
+  ```jsx
+  // Before
+  function App() {
+    <DataBrowserRouter>
+      <Route path="/" element={<Layout />}>
+        <Route index element={<Home />}>
+      </Route>
+    <DataBrowserRouter>
+  }
+
+  // After
+  let router = createBrowserRouter([{
+    path: "/",
+    element: <Layout />,
+    children: [{
+      index: true,
+      element: <Home />,
+    }]
+  }]);
+
+  function App() {
+    return <RouterProvider router={router} />
+  }
+  ```
+
+  If folks still prefer the JSX notation, they can leverage `createRoutesFromElements` (aliased from `createRoutesFromChildren` since they are not "children" in this usage):
+
+  ```jsx
+  let routes = createRoutesFromElements(
+    <Route path="/" element={<Layout />}>
+      <Route index element={<Home />}>
+    </Route>
+  );
+  let router = createBrowserRouter(routes);
+
+  function App() {
+    return <RouterProvider router={router} />
+  }
+  ```
+
+  And now they can also hook into HMR correctly for router disposal:
+
+  ```
+  if (import.meta.hot) {
+    import.meta.hot.dispose(() => router.dispose());
+  }
+  ```
+
+  And finally since `<RouterProvider>` accepts a router, it makes unit testing easer since you can create a fresh router with each test.
+
+  **Removed APIs**
+
+  - `<DataMemoryRouter>`
+  - `<DataBrowserRouter>`
+  - `<DataHashRouter>`
+  - `<DataRouterProvider>`
+  - `<DataRouter>`
+
+  **Modified APIs**
+
+  - `createMemoryRouter`/`createBrowserRouter`/`createHashRouter` used to live in `@remix-run/router` to prevent devs from needing to create their own `history`. These are now moved to `react-router`/`react-router-dom` and handle the `RouteObject -> AgnosticRouteObject` conversion.
+
+  **Added APIs**
+
+  - `<RouterProvider>`
+  - `createRoutesFromElements` (alias of `createRoutesFromChildren`)
+
