v0.22.0

Added

• Add a Pro-only dead letter queue panel that lists discarded jobs newest first, with ID, kind, queue, priority, and tag filters, dead letter autocomplete, and More/Fewer controls to inspect jobs and retry them as new jobs. Live updates start paused and can be enabled independently of the Jobs pane. PR #711.

Changed

• Upgrade River to v0.49.0. PR #703.
• Require Node.js 24.15+ or 26+ for frontend development and use Node.js 24.21.0 in CI and container builds to support the updated test dependencies. PR #690.

Fixed

• Show queues whose concurrency metadata is missing, null, or {} as having no concurrency override, matching how River Pro interprets them, and stop showing a zero concurrency config for producers that report none. PR #704.
• Reject negative queue concurrency global_limit and local_limit values with a 400 error instead of storing them. PR #704.
• Keep workflow diagram layouts compatible with Dagre's package exports after dependency upgrades. PR #687.
