     *Victor Costan*
 
-*   `#pluck` can be used on a relation with `select` clause.
-    Fixes #7551.
-    Backport of #8176.
-
-    Example:
-
-        Topic.select([:approved, :id]).order(:id).pluck(:id)
-
-    *Yves Senn*
-
 *   Use `nil?` instead of `blank?` to check whether dynamic finder with a bang
     should raise RecordNotFound.
     Fixes #7238.
