 # `@react-router/dev`
 
+## 7.10.0-pre.0
+
+### Minor Changes
+
+- Stabilize `future.v8_splitRouteModules`, replacing `future.unstable_splitRouteModules` ([#14595](https://github.com/remix-run/react-router/pull/14595))
+  - ⚠️ This is a breaking change if you have begun using `future.unstable_splitRouteModules`. Please update your `react-router.config.ts`.
+
+- Stabilize `future.v8_viteEnvironmentApi`, replacing `future.unstable_viteEnvironmentApi` ([#14595](https://github.com/remix-run/react-router/pull/14595))
+  - ⚠️ This is a breaking change if you have begun using `future.unstable_viteEnvironmentApi`. Please update your `react-router.config.ts`.
+
+### Patch Changes
+
+- Load environment variables before evaluating `routes.ts` ([#14446](https://github.com/remix-run/react-router/pull/14446))
+
+  For example, you can now compute your routes based on [`VITE_`-prefixed environment variables](https://vite.dev/guide/env-and-mode#env-variables):
+
+  ```txt
+  # .env
+  VITE_ENV_ROUTE=my-route
+  ```
+
+  ```ts
+  // app/routes.ts
+  import { type RouteConfig, route } from "@react-router/dev/routes";
+
+  const routes: RouteConfig = [];
+  if (import.meta.env.VITE_ENV_ROUTE === "my-route") {
+    routes.push(route("my-route", "routes/my-route.tsx"));
+  }
+
+  export default routes;
+  ```
+
+- Updated dependencies:
+  - `react-router@7.10.0-pre.0`
+  - `@react-router/node@7.10.0-pre.0`
+  - `@react-router/serve@7.10.0-pre.0`

 # `react-router`
 
+## 7.10.0-pre.0
+
+### Minor Changes
+
+- Stabilize `fetcher.reset()` ([#14545](https://github.com/remix-run/react-router/pull/14545))
+  - ⚠️ This is a breaking change if you have begun using `fetcher.unstable_reset()`
+
+- Stabilize the `dataStrategy` `match.shouldRevalidateArgs`/`match.shouldCallHandler()` APIs. ([#14592](https://github.com/remix-run/react-router/pull/14592))
+  - The `match.shouldLoad` API is now marked deprecated in favor of these more powerful alternatives
+  - If you're using this API in a custom `dataStrategy` today, you can swap to the new API at your convenience:
+
+    ```tsx
+    // Before
+    const matchesToLoad = matches.filter((m) => m.shouldLoad);
+
+    // After
+    const matchesToLoad = matches.filter((m) => m.shouldCallHandler());
+    ```
+
+  - `match.shouldRevalidateArgs` is the argument that will be passed to the route `shouldRevaliate` function
+  - Combined with the parameter accepted by `match.shouldCallHandler`, you can define a custom revalidation behavior for your `dataStrategy`:
+
+  ```tsx
+  const matchesToLoad = matches.filter((m) => {
+    const defaultShouldRevalidate = customRevalidationBehavior(
+      match.shouldRevalidateArgs,
+    );
+    return m.shouldCallHandler(defaultShouldRevalidate);
+    // The argument here will override the internal `defaultShouldRevalidate` value
+  });
+  ```
+
+### Patch Changes
+
+- Fix a Framework Mode bug where the `defaultShouldRevalidate` parameter to `shouldRevalidate` would not be correct after `action` returned a 4xx/5xx response (`true` when it should have been `false`) ([#14592](https://github.com/remix-run/react-router/pull/14592))
+  - If your `shouldRevalidate` function relied on that parameter, you may have seen unintended revalidations
+
+- Fix `fetcher.submit` failing with plain objects containing a `tagName` property ([#14534](https://github.com/remix-run/react-router/pull/14534))
+- [UNSTABLE] Add `unstable_pattern` to the parameters for client side `unstable_onError`, refactor how it's called by `RouterProvider` to avoid potential strict mode issues ([#14573](https://github.com/remix-run/react-router/pull/14573))
+- Add new `unstable_useTransitions` flag to routers to give users control over the usage of [`React.startTransition`](https://react.dev/reference/react/startTransition) and [`React.useOptimistic`](https://react.dev/reference/react/useOptimistic). ([#14524](https://github.com/remix-run/react-router/pull/14524))
+  - Framework Mode + Data Mode:
+    - `<HydratedRouter unstable_transition>`/`<RouterProvider unstable_transition>`
+    - When left unset (current default behavior)
+      - Router state updates are wrapped in `React.startTransition`
+      - ⚠️ This can lead to buggy behaviors if you are wrapping your own navigations/fetchers in `React.startTransition`
+      - You should set the flag to `true` if you run into this scenario to get the enhanced `useOptimistic` behavior (requires React 19)
+    - When set to `true`
+      - Router state updates remain wrapped in `React.startTransition` (as they are without the flag)
+      - `Link`/`Form` navigations will be wrapped in `React.startTransition`
+      - A subset of router state info will be surfaced to the UI _during_ navigations via `React.useOptimistic` (i.e., `useNavigation()`, `useFetchers()`, etc.)
+        - ⚠️ This is a React 19 API so you must also be React 19 to opt into this flag for Framework/Data Mode
+    - When set to `false`
+      - The router will not leverage `React.startTransition` or `React.useOptimistic` on any navigations or state changes
+  - Declarative Mode
+    - `<BrowserRouter unstable_useTransitions>`
+    - When left unset
+      - Router state updates are wrapped in `React.startTransition`
+    - When set to `true`
+      - Router state updates remain wrapped in `React.startTransition` (as they are without the flag)
+      - `Link`/`Form` navigations will be wrapped in `React.startTransition`
+    - When set to `false`
+      - the router will not leverage `React.startTransition` on any navigations or state changes
+
+- Fix the promise returned from `useNavigate` in Framework/Data Mode so that it properly tracks the duration of `popstate` navigations (i.e., `navigate(-1)`) ([#14524](https://github.com/remix-run/react-router/pull/14524))
+- Fix internal type error in useRoute types that surfaces when skipLibCheck is disabled ([#14577](https://github.com/remix-run/react-router/pull/14577))
+- Preserve `statusText` on the `ErrorResponse` instance when throwing `data()` from a route handler ([#14555](https://github.com/remix-run/react-router/pull/14555))
+- Optimize href() to avoid backtracking regex on splat ([#14329](https://github.com/remix-run/react-router/pull/14329))
