Important upgrade note:

  • A v0.3.0 fleet must stop completely before v0.4.0 is deployed. The two versions cannot share a fleet because the peer tunnel protocol and large Workers KV value references are incompatible.

Highlights:

  • Add initial support for Workers KV, Queues, Workflows, and R2 bindings. celld can deploy these bindings from the corresponding Wrangler configuration.

  • Add celld dev for local development. It rebuilds the application automatically and uses a persistent local object store, so it does not require Docker or a cloud bucket.

  • Nodes can adopt a new deployment without restarting. Existing requests finish on the old deployment, while new requests use the new deployment. Durable Objects move at safe points and retain their storage and hibernatable WebSockets.

  • Strengthen the Durable Object output gate. It now applies one ordering rule to responses, outbound calls, Queue deliveries, and WebSocket sends. Read-only output waits for earlier request or alarm writes to become durable.

  • Route proxied fetch, RPC, and WebSocket calls through one versioned peer tunnel. Request bodies stream to the owner. celld does not retry a call after transmission starts because it does not retain a copy of the body.

  • Improve graceful shutdown with batched handoffs, drain tokens, successor acknowledgements, and full snapshots that reduce successor replay. Configure the orchestrator stop grace to cover the drain-token wait, handoff, and no-progress interval.

  • Add commands to list cells and inspect or manage Workers KV namespaces and Queues: - celld cell list - celld kv get, celld kv put, celld kv delete, celld kv list, and celld kv info - celld kv bulk get, celld kv bulk put, and celld kv bulk delete - celld queue info, celld queue peek, celld queue purge, celld queue pause, celld queue resume, and celld queue redrive The cell and KV listings support pagination, full traversal, and newline-delimited JSON.

  • Move the public health endpoint from /__celld/health to /.well-known/celld/health. Update load-balancer and readiness checks when you upgrade.

  • Add a configurable request-body limit, with a 1 GiB default, and a per-cell concurrency limit. On Linux, memory-pressure handling now also accounts for active cgroup memory.

  • Add support for Amazon EKS Pod Identity credentials from the injected environment variables and authorization-token file.

  • Issues fixed: - #148 - #161 - #163 - #165 - #166 - #167 - #168 - #170
