Changelog

Sourced from react-router's changelog.

v7.18.0

Patch Changes

• Fix server handler prerender responses when using ssr: false and future.v8_trailingSlashAwareDataRequests: true. Avoids false positive "SPA Mode" detection when serving prerendered paths (#15173)
• Use the ServerRouter nonce for nonce-aware SSR components when they don't provide their own value so strict CSP pages can load them. (#15170)
• Use turbo-stream to serialize and deserialize Framework Mode hydration errors (#15175)
• Precompute route branch matchers to avoid recompiling route path regexes during matching (#15186)
• Use the constructed request URL host when validating action request origins. (#15185)
• Remove the un-documented custom error serialization logic from Data Mode SSR built-in hydration flows (#15175)
• Validate protocols in RSC render redirects (#15177)
• Consolidate url normalization logic and better handle mixed slashes (#15176)

v7.17.0

Minor Changes

• Ship a subset of the official documentation inside the react-router package (#15121)
  • Markdown docs are now available in node_modules/react-router/docs, letting AI coding agents and the React Router agent skills read official docs locally
  • Excludes auto-generated API docs (api/), community/ content, and tutorials (tutorials/)

v7.16.0

Minor Changes

• Stabilize future.unstable_trailingSlashAwareDataRequests as future.v8_trailingSlashAwareDataRequests (#15098)

Patch Changes

• Disable manifest path when lazy route dicovery is disabled (#15068)

• Fix browser URL creation to use the configured history window instead of the global window. (#15066)

  • Pass the history/router window through to createBrowserURLImpl so custom window contexts keep the correct URL origin.

• Fix useNavigation() return type to preserve discriminated union across navigation states (#15095)

• Widen MetaDescriptor script:ld+json type from LdJsonObject to LdJsonObject | LdJsonObject[] to permit multiple JSON-LD schemas in a single <script type="application/ld+json"> tag emitted by <Meta /> (#15082)
