 == Using multiple node IDs
 
 A node header can contain multiple `ID` columns.
-The relationship data must then use a matching number of `START_ID` / `END_ID` columns as references to the composite value of those ID columns.

+Starting from 2025.07, the relationship data must then use a matching number of `START_ID` / `END_ID` columns as references to the composite value of those ID columns.
 This implies using `string` as `id-type`.
 
 For each `ID` column, you can specify to store its values as different node properties.
 However, the composite value cannot be stored as a node property.

 Incremental import doesn't support the use of multiple node identifiers.
 This functionality is only available with a full import.
