| 16:23 | Improve fts5 integrity-check so that it checks that DESC queries return the same as ASC. Change the poslist format slightly to make room for a delete-flag. check-in: 49c1e745 user: dan tags: fts5 | |

| 15:45 | Merge trunk changes with this branch. check-in: 14274391 user: dan tags: fts5 | |
| 15:37 | When scanning the full-text index as part of the fts5 integrity-check, also run a point query for every term and verify that these results are consistent with those found by the linear scan. check-in: ce972f6a user: dan tags: fts5 | |
| 12:25 | Remove an unreachable branch from the OP_VCreate opcode (merge accidental fork in trunk). check-in: 2fbfec62 user: dan tags: trunk | |
