> API versioning, webhooks, delivered status, four tracker integrations.

## Highlights

### API v1 and a stability commitment

The API now lives at `/api/v1`. Same endpoints, same auth, same shapes — the version in the path is a commitment. Breaking changes only ship in a new version, the previous version keeps working for at least 6 months, and changes are announced 30 days in advance. Old unversioned paths continue working with a deprecation header.

### Outbound webhooks

Real-time signed event delivery for nodes and phases. Register a URL, choose your events, receive payloads as things change. HMAC-SHA256 signatures for verification. Connects ProductBrain to Make.com, Zapier, n8n, or any workflow tool that accepts webhooks.

### Delivered status — the tracker handoff

Jobs now have a three-step lifecycle: in progress → delivered → done. When your delivery tracker signals that the linked work is complete, the job moves to `delivered`. Moving to `done` means someone has verified the proof condition is actually met. A closed ticket is a claim. A done job is proof.

### Four tracker integrations

Linear, GitHub, Jira, and Azure DevOps — via importable Make.com blueprints, \~30-minute setup each. Jobs flow out as trackable containers, completion signals flow back as `delivered`. Step-by-step guides for each platform.

## Other improvements

* Deprecation headers on old API paths with Link to successor
* Webhook health monitoring (last delivery time and status)
* GitHub integration verified end-to-end against real GitHub API
