Hello
The `ActiveRecord::Relation#in_batches`, similar to `ActiveRecord::Relation#find_in_batches`, but which yields a collection ofActiveRecord::Relation objects has been merged into master via https://github.com/rails/rails/pull/20933. If I'm not mistaken, this is not backported to older Rails versions—I've checked out the v4.2.5.rc2 tag, but couldn't find the method.
Is there a reason why this is not backported to older Rails versions?
