v2.0.0-beta.45 replaces Alchemy.Secret and Alchemy.Variable with plain effect/Config, and ships two new Worker abstractions — Cloudflare.RpcWorker and Cloudflare.RpcDurableObjectNamespace — that take a typed Effect RPC schema directly and hand back typed clients.
v2.0.0-beta.44 adds a new Cloudflare.ZarazConfig resource, a bundle analyzer for Workers, and Artifacts binding support in dev, plus a handful of bundler and dev-server fixes.
v2.0.0-beta.43 includes a new alchemy/Planetscale provider, improvements to how Resources and Bindings are encapsulated in Layers, and a handful of other fixes.
A big internal rewrite of the Cloudflare Worker runtime fixes hung requests and dropped responses from RPC and HTTP API workers. The Worker entrypoint is now a thin shell over WorkerBridge.ts, scopes are linearized per request, and the same schema-driven pattern (HTTP API, RPC, and Durable Object proxies) is now stable end-to-end.
Cloudflare local dev gains a real Vite dev server (HMR, SSR, client + worker in one process), AiGateway stops reporting spurious updates on every deploy, the Worker HTTP server returns generic 500s while logging the full Cause server-side, and a handful of fixes around entrypoint generation, container startup, and the dev lockfile.
