remix@3.0.0-beta.6

⚠️ Breaking Changes

• Legacy package-aligned `remix/*` aliases have been removed. Update imports to use canonical entrypoints like `remix/middleware/auth`, `remix/data-table/postgres`, `remix/router`, etc.
• `createAssetServer()` from `remix/assets` now uses `allowFiles` and `denyFiles` instead of `allow` and `deny` for file path access rules.
• Custom `encode` and `decode` functions in `remix/cookie` are now treated as the complete cookie value codec. Custom encoded values are signed and serialized as-is, without Remix's default base64 encoding. The default codec retains base64-safe representation.
• Route patterns now use delimiter-bounded params. Params stop at raw `/` and `.`, but not `-`. Ambiguous adjacent captures are rejected, and matching work is bounded.
• Href helpers from `remix/route-pattern/href` and `remix/routes` now take search parameters in a `searchParams` options property. The options object also accepts a `baseURL`.
• `remix/middleware/session` now makes session cookies HTTP-only by default when `httpOnly` is omitted. Set `httpOnly: false` explicitly if client-side JavaScript needs to read the cookie. `Cookie.httpOnly` now returns `boolean | undefined`.
• Run tests with `remix test` instead of the removed `remix-test` executable. Move settings from `remix-test.config.ts` or `.js` into the `test` property of `remix.json`.
• The programmatic `runRemixTest()` API from `remix/test/cli` now accepts typed runner options instead of raw command-line arguments.
• Browser frame resolvers now receive one options object instead of positional `signal` and `target` arguments. Destructure `signal` and `target` from the options object.
• Replace the removed adapter and migration-runner APIs with a concrete database and its lifecycle methods. Use dialect factories like `createPostgresDatabase()` and call methods like `db.migrate(migrations)` instead of `migrationRunner.migrate()`.
