-The feature gate `receiver.mongodb.removeDatabaseAttr` once enabled will remove database name attribute, 
-because both resource and datapoint attributes are called database.
+**BETA**: `receiver.mongodb.removeDatabaseAttr`
 
-This feature gate will eventually be enabled by default, and eventually the old implementation will be removed. It aims
-to give users time to migrate to the new implementation. The target release for this featuregate to be enabled by default
-is 0.94.0.
+The feature gate `receiver.mongodb.removeDatabaseAttr` is enabled by default but may be disabled.
+Unless disabled, it will remove the database name attribute from data points because it is already found on the resource.
+This feature gate will eventually be removed.
