| 11:02 | Fix the TCL interface so that SQL functions implemented in TCL honor the "nullvalue" setting. Also remove from the TCL interface some unused legacy UTF8 translation code left over from SQLite2. (check-in: c1f10a2643 user: drh tags: trunk) | |
| 00:25 | Further attempts to optimize out unnecessary ORDER BY clauses. (check-in: 6744d9a37f user: drh tags: qp-enhancements) | |

| 15:19 | More lenient handling of ORDER BY optimization in joins with mixed ASC/DESC. This is a better and less restrictive fix for the problem addressed by the previous check-in. (check-in: abcf6a5d05 user: drh tags: trunk) | |
