AI Summary

This release introduces namespaces as a core runtime routing dimension across the engine and SDKs, alongside the launch of the Worker Compose daemon for managing worker graphs. It also includes significant improvements to observability, including persistent traces on disk and trigger-driven updates.

Key Highlights

  • Namespace support as a runtime routing dimension across Engine and SDKs.
  • New Worker Compose daemon for declaring projects and supervising worker graphs.
  • Persistent traces on disk with a redesigned observability configuration UI.
  • Trigger-driven trace updates replacing live streams and console polling.
  • Improved telemetry with rate-limited heartbeats and aggregated CLI usage.

Breaking Changes

  • Namespace routing dimension changes may require code updates to explicitly specify namespaces.
  • Removal of live streams and console polling for trace updates.
  • Queue providers are now scoped by namespace, requiring configuration updates.

New Features

  • Namespace as a runtime routing dimension (engine + SDKs)
  • Worker-compose daemon
  • Persist traces on disk
  • Trigger-driven trace updates
  • Redesigned observability configuration UI
