| 20:37 | Clarify the computation of compatible isOrdered by in the plan solver of the query planner. (Closed-Leaf check-in: b5e8fd57 user: drh tags: query-planner-fix) | |

| 16:50 | Oops! This check-in was on trunk. But it contains a debugging printf(). Original comment: When the estimated cost to do a sort overwhelms the estimated cost to do individual table lookups, make sure that the table lookup costs are still taken into consideration when selecting the lookup algorithm.
