## @react-router/serve 8

### Breaking changes

- The minimum supported Node version is now 22.22.0. (8.0.0) — [release notes](https://github.com/remix-run/react-router/blob/eb5175819b00ff4077029b8d14a53e0878b6356c/packages/react-router-serve/CHANGELOG.md#v800)

### New APIs and options

- Supports API-only builds by serving client documents and forwarding data and route discovery requests to the React Router runtime. (8.5.0) — [release notes](https://github.com/remix-run/react-router/blob/eb5175819b00ff4077029b8d14a53e0878b6356c/packages/react-router-serve/CHANGELOG.md#v850)

### Behavior and default changes

- Files under /.well-known/ are served from the client build directory instead of falling through to the request handler; other dotfiles remain hidden. (8.3.1) — [release notes](https://github.com/remix-run/react-router/blob/eb5175819b00ff4077029b8d14a53e0878b6356c/packages/react-router-serve/CHANGELOG.md#v831)

### Fixes and other changes

### Fixes and other changes
