## 12.134. Release 0.110

## General Changes

- Fix result truncation bug in window function `row_number()` when performing a partitioned top-N that chooses the maximum or minimum `N` rows. For example:

      SELECT * FROM (
          SELECT row_number() OVER (PARTITION BY orderstatus ORDER BY orderdate) AS rn,
              custkey, orderdate, orderstatus
          FROM orders
      ) WHERE rn <= 5;
