| 18:49 | Add the highly-experimental "PRAGMA noop_update=TRUE" command. (Leaf check-in: de2e3717 user: drh tags: pragma-noop-update) | |
| 18:03 | Hack to have multiple connections to a single file share a single memory mapping of the databse file. (check-in: ec37ad6d user: dan tags: shared-mapping-hack) | |
