remix v3.0.0-rc.2

Pre-release Changes

• BREAKING CHANGE: Asset fingerprints from remix/assets now use hashes of the final file contents. Replace fingerprint: { buildId } with fingerprint: true. If you use a persistent files.cache, move the build identifier to files.cacheKey to keep reusing cached files across server restarts. See the asset server migration steps (see #11706).

• BREAKING CHANGE: Browser scripts served by remix/assets now use import maps to resolve imports. Replace separate getHref() and getPreloads() calls with getScriptEntry(), and render <ImportMap value={importMap} /> from remix/ui/server before the entry's preloads and module script.

  Apps with client entries or HMR should also configure remix/multiple-import-maps-polyfill for browsers that need support for import maps added at runtime. New apps include this setup. Existing apps should follow the asset server migration steps, including changes to custom rendering integrations (see #11706).

• BREAKING CHANGE: remix/router now returns 405 Method Not Allowed with an Allow header when a URL matches a route but the request method does not. These requests previously reached defaultHandler, which returned 404 by default. Register an ANY route if you need a custom handler for every method at that URL.

  GET routes now also serve HEAD requests with the same status and headers and an empty body. Explicit HEAD routes still take precedence. See the router release notes (see #11767).

• BREAKING CHANGE: Custom browser HMR events from remix/assets and remix/node-hmr now carry update data in a data record. Replace top-level timestamp and updates fields with a named entry such as data: { 'my-tool@1': { timestamp, updates } }.

  Apps using the standard asset server and createBrowserHmrChannel() integration need no changes to their event handling. See the HMR migration example (see #11706).

• Added remix/multiple-import-maps-polyfill to load and preload JavaScript modules that depend on import maps added at runtime. importModule() uses native imports in browsers with support and the polyfill in other browsers. See the usage guide (see #11706).

• Fixed scroll timing during frame navigation and history restoration in remix/ui. Frames now show HTML validation and error responses with 3xx or 4xx status codes, and browsers without NavigateEvent.sourceElement support fall back to full document navigation. See the UI release notes.
