 18. **Persistent Workspace Settings:** Added a `Workspace` database model to persist global dashboard settings like Name and Timezone.
 19. **Dynamic UI Integration:** Completely refactored the navigation and boards to build columns and tabs dynamically from the live database user list.
 20. **Functional Search:** Implemented a real-time task search feature. Clicking the search icon now reveals an inline search bar that filters tasks by title, description, or tags across all views.
+21. **Advanced Audit Filtering:** Upgraded the Audit Log for Admins with a search bar and a granular event type filter. Admins can now filter the history by specific actions (e.g., "deleted tasks", "moved tasks", "user management") and search through summaries in real-time.
 
 ### Phase 3: Advanced Features
 - **Real-time Notifications:** Explore WebSockets for task assignments.
