## Seen Status Tracking

Notifications now include seen status tracking with automatic visibility detection, timestamps, and API endpoints for filtering by seen/unseen state.

**What's new:**

- Automatic "seen" marking when notifications become visible in UI
- First-seen timestamp capture for each notification
- Bulk operations to mark individual or multiple notifications as seen
- New API endpoints for seen status management and filtering

## Inbox Timezone Awareness

The Inbox component now delivers notifications based on each subscriber's timezone instead of the system timezone, improving the in-app experience for users across different locations.

## Fixed: Dynamic Subscriber ID Handling

<Inbox/> and <Bell/> components now properly refresh when `subscriberId` changes from `undefined` to a valid value.

**Fix details:**

- Automatic session reinitialization on subscriberId changes
- Complete state refresh when subscriber context updates
- Applies to @novu/react, @novu/js, and @novu/react-native packages

## Custom Data Filtering

Filter inbox notifications by message data attributes using the new `data` query parameter.

```javascript
const queryParams = {
  data: JSON.stringify({
    'order_status': 'pending',
    'priority': 'high'
  })
}
```

**Implementation:**

- AND logic filtering - all specified key-value pairs must match
- Input validation and sanitization prevent injection attacks
- Graceful handling of malformed JSON input
