| 16:07 | One of the optimizations of check-in [de9c86c9e4cdb34f] does not work for terms originating in the ON/USING clause, as demonstrated by forum post 6cf3bb457c3f4685. This check-in disables that optimization for ON/USING terms. Also improve the TreeView display for the resulting "true"/"false" nodes to show that they originate from the ON/USING clause.

| 19:29 | Attempt to omit ORDER BY clauses from FROM-clause subqueries if those ORDER BY clauses do not affect the output. See forum thread 2d76f2bcf65d256a for discussion. This can help the query flattener in some cases, resulting in faster query plans. The current implemention does not always work. (check-in: ef97c3e7c3 user: drh tags: omit-subquery-order-by) | |
| 16:39 | Change references to the schema table in sqlite3_analyzer to the new SQLITE_SCHEMA name. (check-in: 3beb77d6a7 user: drh tags: trunk) | |

This can happen during a UNION ALL query flattening while processing a virtual table update in which the first term of the vector is repeated. Forum post 16ca0e9f32. (check-in: 2547cfe38f user: drh tags: trunk) | |
| 01:11 | Ensure that TK_SELECT_COLUMN Expr nodes always have their iTable field set to to the number of columns in the vector. This is not strictly necessary. It just simplifies the state description and make the code easier to reason about. (check-in: 026f08d4cf user: drh tags: trunk) | |
| 00:07 | Fix an incorrect comment on testcase misc1-27.0. No changes to code. (check-in: 49829ae322 user: drh tags: trunk) | |

| 12:08 | Fix a harmless assertion fault discovered by OSSFuzz. The assertion fault is harmless because the assert() checks a condition that that is harmless if false and the assert() is disabled in production builds. (check-in: 79443aabe1 user: drh tags: trunk) | |
