#15713 3c75cad Thanks @jamesopstad! - Define experimental Cloudflare configuration with a single default export
Experimental cloudflare.config.ts files now define settings and resources together in a default-exported defineConfig() call. Add a Worker under worker, add Containers to the containers array, or omit both to provide settings only.
```
import * as entrypoint from "./src/index.ts" with { type: "cf-worker" };

export default defineConfig({
	accountId: "...",
	complianceRegion: "public",
	worker: {
		name: "my-worker",
		compatibilityDate: "2026-09-18",
		entrypoint,
	},
});
```
#15707 95af41d Thanks @halfstack-dev! - Support nested D1 migration layouts in readD1Migrations()
readD1Migrations() now accepts the same migrationsDir / migrationsPattern options Wrangler uses, so Vitest can apply Drizzle-style nested files such as 0001_init/migration.sql. Discovery is shared with Wrangler via @cloudflare/workers-utils, so the test path and wrangler d1 migrations apply stay aligned.
The original readD1Migrations(migrationsPath) signature still reads only top-level *.sql files in that directory.
