## 6.5.0

This release introduces support for [Optional Route Segments](https://github.com/remix-run/react-router/issues/9546). Now, adding a `?` to the end of any path segment will make that entire segment optional. This works for both static segments and dynamic parameters.

**Optional Params Examples**

- `<Route path=":lang?/about>` will match:
  - `/:lang/about`
  - `/about`
- `<Route path="/multistep/:widget1?/widget2?/widget3?">` will match:
  - `/multistep`
  - `/multistep/:widget1`
  - `/multistep/:widget1/:widget2`
  - `/multistep/:widget1/:widget2/:widget3`

**Optional Static Segment Example**

- `<Route path="/home?">` will match:
  - `/`
  - `/home`
- `<Route path="/fr?/about">` will match:
  - `/about`
  - `/fr/about`

### Minor Changes

- Allows optional routes and optional static segments ([#9650](https://github.com/remix-run/react-router/pull/9650))

### Patch Changes

- Stop incorrectly matching on partial named parameters, i.e. `<Route path="prefix-:param">`, to align with how splat parameters work. If you were previously relying on this behavior then it's recommended to extract the static portion of the path at the `useParams` call site: ([#9506](https://github.com/remix-run/react-router/pull/9506))

```jsx
// Old behavior at URL /prefix-123
<Route path="prefix-:id" element={<Comp /> }>

function Comp() {
  let params = useParams(); // { id: '123' }
  let id = params.id; // "123"
  ...
}

// New behavior at URL /prefix-123
<Route path=":id" element={<Comp /> }>

function Comp() {
  let params = useParams(); // { id: 'prefix-123' }
  let id = params.id.replace(/^prefix-/, ''); // "123"
  ...
}
```

  - `@remix-run/router@1.0.4`

## 6.4.3

### Patch Changes

- `useRoutes` should be able to return `null` when passing `locationArg` ([#9485](https://github.com/remix-run/react-router/pull/9485))
- fix `initialEntries` type in `createMemoryRouter` ([#9498](https://github.com/remix-run/react-router/pull/9498))

- Enhance console error messages for invalid usage of data router hooks ([#9311](https://github.com/remix-run/react-router/pull/9311))
- If an index route has children, it will result in a runtime error. We have strengthened our `RouteObject`/`RouteProps` types to surface the error in TypeScript. ([#9366](https://github.com/remix-run/react-router/pull/9366))
- Updated dependencies:
  - `@remix-run/router@1.0.2`

## 6.4.0

Whoa this is a big one! `6.4.0` brings all the data loading and mutation APIs over from Remix. Here's a quick high level overview, but it's recommended you go check out the [docs][rr-docs], especially the [feature overview][rr-feature-overview] and the [tutorial][rr-tutorial].

**New APIs**

- Create your router with `createMemoryRouter`
- Render your router with `<RouterProvider>`
- Load data with a Route `loader` and mutate with a Route `action`
- Handle errors with Route `errorElement`
- Defer non-critical data with `defer` and `Await`

**Bug Fixes**

- Path resolution is now trailing slash agnostic (#8861)
- `useLocation` returns the scoped location inside a `<Routes location>` component (#9094)

**Updated Dependencies**

- `@remix-run/router@1.0.0`
