| 15:57 | Increase Table.tabFlags from 8 to 32 bits. (check-in: 7e14044c user: drh tags: trunk) | |
| 15:06 | Remove two redundant initializations from the virtual table logic. (check-in: 6bd82b95 user: drh tags: trunk) | |
| 14:48 | Always use the IsVirtual() macro to determine if a Table object is a virtual table. Slightly smaller and faster code. (check-in: 6affb1c8 user: drh tags: trunk) | |
