+Add a new `future.v3_relativeSplatPath` flag to implement a breaking bug fix to relative routing when inside a splat route. For more information, please see the React Router [`6.21.0` Release Notes](https://github.com/remix-run/react-router/blob/release-next/CHANGELOG.md#futurev7_relativesplatpath) and the [`useResolvedPath` docs](https://remix.run/hooks/use-resolved-path#splat-paths).

 If `undefined`, this defaults to the closest route in context. If a parent route renders a `<Form>` but the URL matches deeper child routes, the form will post to the parent route. Likewise, a form inside the child route will post to the child route. This differs from a native [`<form>`][form_element] that will always point to the full URL.

+## Splat Paths
+
+The original logic for React Router's `useResolvedPath` hook behaved differently for splat paths which in hindsight was incorrect/buggy behavior. Please see the [React Router Docs][rr-use-resolved-path-splat] for a longer explanation but this was determined to be a "breaking bug fix" and thus was fixed behind a future flag in React Router and exposed up through Remix's future flags. This will become the default behavior in Remix v3, so it is recommended to update your applications at your convenience to be better prepared for the eventual v3 upgrade.
+
+It should be noted that this is the foundation for all relative routing in Remix, so this applies to the following relative path code flows as well:
+
+- `<Link to>`
+- `useNavigate()`
+- `useHref()`
+- `<Form action>`
+- `useSubmit()`
+- Relative path `redirect` responses returned from loaders and actions
+
+### Behavior without the flag
+
+When this flag is not enabled, the default behavior is that when resolving relative paths inside of a splat route, the splat portion of the path is ignored. So, within a `routes/dashboard.$.tsx` file, `useResolvedPath(".")` would resolve to `/dashboard` even if the current URL was `/dashboard/teams`.
+
+### Behavior with the flag
+
+When you enable the flag, this "bug" is fixed so that path resolution is consistent across all route types, and `useResolvedPath(".")` always resolves to the current pathname for the contextual route. This includes any dynamic param or splat param values, so within a `routes/dashboard.$.tsx` file, `useResolvedPath(".")` would resolve to `/dashboard/teams` when the current URL was `/dashboard/teams`.
