 ### Enhancements
 
 - New Cluster Manager UI enhancements:
 
-    - Perform node actions from the **Nodes** screen to verify nodes, set a node as primary or secondary, remove nodes, and manage node alert settings.

-    - Categorize databases with custom tags. When you add new tags to a database, the keys and values already used by existing tags will appear as suggestions.
