### AI history

***

## 1.1.7

### Workflows

* `Workflow`, `defineAgent`, `WorkflowContext`, and `WorkflowRunner` for multi-step AI pipelines.
* `DNotifier.runWorkflow` as the primary execution entry point.
* Agent registration via `.registerAgents()`.
* `WorkflowError` for validation and runtime failures.

→ [Workflows overview](/product-docs/workflows-and-agents/overview.md)

### Observability

* Optional workflow observability when `observability: true` on `Workflow`.

→ [Workflow observability](/product-docs/workflows-and-agents/observability.md)

### Auth

* `authToken` available on `DNotifier` after successful `connect()`.

### Core SDK (1.1.7 baseline)

## Upgrade notes

### From 1.1.7 → 1.1.9

1. Update `pubspec.yaml`: `dnotifier: ^1.1.9` or later
2. Run `dart pub get` / `flutter pub get`
3. No breaking API changes for basic `connect` / `send` usage

### Workflows

Register all agents before calling `runWorkflow`:

```dart
final workflow = DNotifier.Workflow(
  name: 'my-workflow',
  entry: (ctx) async { /* ... */ },
).registerAgents({'my-agent': myAgent});
```

Use `transport: 'http'` for workflow execution.
