AI Summary

This release introduces namespaces as a core runtime routing dimension and advances the Worker Compose daemon capabilities. It also significantly improves observability by persisting traces to disk and redesigning the configuration UI, alongside various fixes for telemetry, SDK behavior, and queue provider scoping.

Key Highlights

Namespace support added as a runtime routing dimension for Engine and SDKs.
New Worker Compose daemon allows declaring projects, starting them as graphs, and supervising them.
Traces are now persisted on disk with a redesigned observability configuration UI.
Observability updates switched to a trigger-driven model, removing live streams and console polling.
Queue providers are now scoped by namespace to prevent conflicts.

Breaking Changes

Observability updates now use trigger-driven models instead of live streams and console polling.
Namespace is now a runtime routing dimension, potentially affecting existing routing logic.
Queue providers are scoped by namespace.

New Features

Namespace as a runtime routing dimension (engine + SDKs)
Worker-compose daemon for project graph management
Persist traces on disk
Redesigned observability configuration UI
Compact trace summaries
