celld Files

Upgrading from v0.4.1 requires stopping the whole fleet first.

Highlights:

• Support for Containers and the Cloudflare Sandbox SDK.
• Support for worker_loaders in wrangler.json. Loaded Workers can receive service bindings and use a custom outbound fetch handler.
• Service bindings now support fetch() on named entrypoints across Workers.
• RPC support for default service bindings and nested properties. AbortSignal can pass through RPC calls on the same node.
• Choose how long to keep completed Workflow runs, or delete them manually.
• Support for .dev.vars in celld dev, with automatic reloads.
• Support for WASM files in prebuilt deployments.
• Lower memory use per cell and faster KV prefix listings.
• Fixes for nested transactions, facet rollback, and unfinished SQL writes.
• More reliable alarm delivery and background work after a response.
• Database recovery fixes, with lower memory use during recovery and compaction.
• Internal host functions are no longer exposed to application code.
• Configure telemetry with CELLD_OTEL: 1 for the bucket, or an OTLP collector URL.

• [#177]: Pass service bindings to loaded Workers.

• [#198], [#199]: Fix database compaction and restore failures.
• [#200]: Resume async work when another request wakes it.
• [#201]: Recognize minified imports for Node.js builtins.
• [#203]: Fix duplicate WebSocket Close frames.
