## From the publisher

Miniflare v5 prepares Cloudflare local development tooling for the upcoming cf CLI. Miniflare powers local Workers development behind wrangler dev, the Cloudflare Vite plugin, and @cloudflare/vitest-plugin. Most projects should use those tools instead of depending on Miniflare directly, and Miniflare v5 will not require any action. The most significant change is a new configuration shape which aligns Miniflare with cloudflare.config.ts, the programmatic Cloudflare configuration format now available for testing. Other breaking changes include: Removed deprecated APIs and options, such as legacy alpha D1 bindings. Removed now-unused, internal APIs like wrappedBindings Removed Miniflare's built-in module discovery; higher-level tools like Wrangler and the Vite plugin should be providing the module graph. Moved local-only /cdn-cgi routes under /cdn-cgi/local.
