## Version 0.0.17

### New features

#### Dependents sync

`authUpgradeProfileSync` now accepts a `dependents` array to sync family members covered under the user's insurance. Each dependent can be linked to a specific insurance plan by index.

```typescript
authUpgradeProfileSync: {
  insurances: [
    { partner_plan_id: "plan-uuid", member_id: "M001", group_id: "G100" },
  ],
  dependents: [
    {
      first_name: "Alex",
      last_name: "Doe",
      date_of_birth: "2015-06-01",
      relationship_code: "19", // child
      insurance_index: 0,
    },
  ],
}
```

New exported type: `AuthUpgradeDependent`. See the [Profile Sync](/ask-sunny/profile-sync) guide for full details.

#### UI configuration options

`createSunnyChat` and `attachSunnyChat` now accept `fontSize`, `fontFamily`, and `dimensions` for widget customization:

```typescript
const chat = createSunnyChat({
  // ...
  fontSize: "14px",
  fontFamily: "'Inter', sans-serif",
  dimensions: {
    width: "1200px",
    height: "800px",
    triggerMaxWidth: "500px",
  },
});
```

New exported type: `VanillaChatDimensions`.
