| 15:37 | Update fts3/4 so that the 'merge=X,Y' command merges at least, instead of exactly, Y segments from a single level. This matches the documentation. 'merge=X,0' is, as it was in 3.11, an error. (check-in: 64b3cb29 user: dan tags: trunk) | |
| 15:30 | Make the SQLITE_DEFAULT_SYNCHRONOUS and SQLITE_DEFAULT_WAL_SYNCHRONOUS values zero-based to agree with PRAGMA synchronous. (Closed-Leaf check-in: 592d2104 user: drh tags: default-synchronous) | |
