+    - Enhance the changefeed summary to include complete configuration details.
+
+        Previously, you had to pause a changefeed to check its configuration and then resume it. The **Changefeed** page now displays the complete configuration directly in the summary view. This update keeps the edit and view modes consistent and introduces a redesigned layout for better readability. With this update, you can review the current configuration more efficiently.
