2020-05-16
| ||
| 19:00 | Merge trunk enhancements in the reuse-schema branch. (Actual date of this check-in is 2020-05-18.) (check-in: 5af4abe9 user: drh tags: reuse-schema) | |
| 18:01 | The OP_RealAffinity opcode is not necessary after reading values from a virtual table (such as rtree). It is harmless, but it does use CPU cycles. Might as well leave it off. (check-in: dc18d893 user: drh tags: trunk) | |
|
2020-03-05
| ||
