| 19:49 | Handle equality and range constraints on the "term" column of fts5vocab tables. Also have the same module report columns using names instead of indexes. (check-in: 6020d96a user: dan tags: trunk) | |
| 01:00 | Change the code generator for UPDATE to generate code in an order that might run more efficiently in many cases. (Leaf check-in: c6239bf9 user: drh tags: improved-update) | |
