 **Builders and iterators**
 
 If migrating from the previous library ([`oliva/tree`](https://github.com/dakujem/oliva-tree)), the most common problems are caused by
-- the builders not automatically adding an empty root node
-- the iterators iterating over root node
+- the new builders not automatically adding an empty root node
+- the new iterators iterating over root node
 
 For both, see "Materialized path tree without root data" and "Recursive tree without root data" sections above.
