What's New

Older release adds State/Queue capabilities and Cap'n Web transport; newer release updates smol-toml to fix a high-severity DoS vulnerability.

Breaking Changes

  • Experimental `?__agents_rpc=capnweb` endpoint removed
  • `LifecycleServices.starting()` replaced by `status()`
  • `queue()` methods are now asynchronous
  • `QueueItem.created_at` renamed to `createdAt`
  • Legacy `cf_agents_queues` table and in-isolate drain removed

New Features

  • New `State` capability for validated, persistent agent state management
  • New `Queue` capability for durable background job processing with retry policies
  • `useAgent({ transport })` and `AgentClient({ transport })` support for different wire protocols
  • `Queue` supports stable IDs, per-item retry, and deadman timers

Improvements

  • WebSockets capability now owns protocol state sync and connection flags
  • LifecycleServices exposes `name` and `className`
  • WebSocket gains Cap'n Web transport for native callables and streaming

Bug Fixes

  • Fixes a high-severity denial of service via malformed TOML

Upgrade Notes

Note: The provided releases are for different packages (`agents` and `worker-bundler`), so there is no direct upgrade path. For the older release, update `LifecycleServices` to use `status()` and migrate the `cf_agents_queues` table.
