Sourced from react-router's changelog.

v7.15.1

Patch Changes

• Update router to operate on fetcher Maps in an immutable manner to avoid delayed React renders from potentially reading an updated but not yet committed Map. This could result in brief flickers in some fetcher-driven optimistic UI scenarios. (#15028)
• Fix serverLoader() returning stale SSR data when a client navigation aborts pending hydration before the hydration clientLoader resolves (#15022)
• Fix RouterProvider onError callback not being called for synchronous initial loader errors in SPA mode (#15039) (#14942)
• Memoize useFetchers to return a stable identity and only change if fetchers changed (#15028)
• Internal refactor to consolidate mutation request detection through shared utility (#15033)

Unstable Changes

⚠️ Unstable features are not recommended for production use

• Add a new unstable_useRouterState() hook that consolidates access to active and pending router states (RFC: #12358) (#15017)

  • Data/Framework/RSC only — throws when used without a data router

  • This should allow you to consolidate usages of the following hooks which will likely be deprecated and removed in a future major version

    • useLocation
    • useSearchParams
    • useParams
    • useMatches
    • useNavigationType
    • useNavigation

    let { active, pending } = unstable_useRouterState();
    // Active is always populated with the current location
    active.location; // replaces useLocation()
    active.searchParams; // replaces useSearchParams()[0]
    active.params; // replaces useParams()
    active.matches; // replaces useMatches()
    active.type; // replaces useNavigationType()
    // Pending is only populated during a navigation
    pending.location; // replaces useNavigation().location
    pending.searchParams; // equivalent to new URLSearchParams(useNavigation().search)
    pending.params; // Not directly accessible today
    pending.matches; // Not directly accessible today
    pending.type; // Not directly accessible today
    pending.state; // replaces useNavigation().state
    pending.formMethod; // replaces useNavigation().formMethod
    pending.formAction; // replaces useNavigation().formAction
    pending.formEncType; // replaces useNavigation().formEncType
    pending.formData; // replaces useNavigation().formData
    pending.json; // replaces useNavigation().json
    pending.text; // replaces useNavigation().text
