| 08:29 | Only use indexes on expressions to optimize ORDER BY and GROUP BY if the collation sequence matches. Possible fix for [e20dd54a]. (check-in: 37e1900880 user: dan tags: trunk) | |

| 18:17 | The RTREE extension should return SQLITE_CORRUPT_VTAB, not just SQLITE_CORRUPT when it encounters incorrectly formatted shadow tables. (check-in: 0712f057ef user: drh tags: trunk) | |
| 14:47 | Remove an unnecessary branch from the [be436a7f4587ce517ddc] fix. (check-in: fb6ca99b88 user: drh tags: trunk) | |

| 23:53 | Minor size and performance optimization to sqlite3BtreeCloseCursor(). (check-in: 1696933884 user: drh tags: trunk) | |

| 01:33 | Properly dequote column names in tables constructed by an aggregate SELECT. (check-in: 7e0d3e9cb0 user: drh tags: trunk) | |

| 17:53 | Test case for writing to a WITHOUT ROWID virtual table. The TCLVAR virtual table is modified to add a "fullname" column which is the primary key, and to accept update operations against the primary key. (check-in: 6997e00c32 user: drh tags: writable-vtab-without-rowid) | |
| 15:19 | Experimental changes that allow a WITHOUT ROWID virtual table to be writable as long as it has only a single-column PRIMARY KEY. (check-in: ab9ee4c1e6 user: drh tags: writable-vtab-without-rowid) | |
