## 0.4.3-next.0

### Patch Changes

- Updated dependencies
  - @backstage/plugin-catalog-node@2.2.2-next.0
  - @backstage/backend-plugin-api@1.9.2-next.0
  - @backstage/plugin-notifications-node@0.2.27-next.0

## 0.4.2

### Patch Changes

- 744fa1f: Removed duplicated entries that appeared in both `dependencies` and `devDependencies`.
- f399a7a: Added scope-based message update support. When a notification is re-sent with the same `scope` and `notification.updated` is set, the processor now calls `chat.update()` on the existing Slack message instead of sending a duplicate via `chat.postMessage()`. Message timestamps are persisted in a new `slack_message_timestamps` database table with automatic daily cleanup. The processor gracefully degrades to the previous behavior when no database is provided.
