| 23:33 | Enhance the EXISTS-to-JOIN optimization so that it works on EXISTS subqueries that do not have a WHERE clause, and so that it works on nested EXISTS subqueries. (check-in: c1d5295724 user: drh tags: empty-table-optimizations) | |

| 10:10 | Tweak for coverage testing of valueToTextV2(). This changes passes through coverage testing but doesn't look quite right to me, in that this part now differs from its counterpart in valueToText() (which doesn't need this to get coverage for what amounts to the same path). (check-in: dae572912f user: stephan tags: column-text-blob-v2) | |
