| 21:12 | Make sure any window definitions in an ORDER BY clause are removed from the SELECT statement if the ORDER BY clause gets optimized out. (check-in: 23b11967 user: drh tags: winfunc-in-orderby) | |
| 18:00 | Early detection of a corrupt R-Tree in the R-Tree search algorithm. (check-in: 2bf5a4c1 user: drh tags: trunk) | |

| 20:56 | When dropping a view, skip trying to delete from 'sqlite_stat*'. (check-in: 2f5be3a2 user: mistachkin tags: dropViewNoStat) | |
| 19:24 | Change the SQLITE_Stat34 bit of the optimization test-control so that it prevents STAT4 data from being used but allows it to be loaded into the Index objects. This permits STAT4 to be turned on and off on a per-statement basis. (check-in: 489f3caf user: drh tags: trunk) | |
| 18:01 | Experimental change to ANALYZE so that when computing values for sqlite_stat1, it uses the maximum number for the number of rows having equivalent values, rather than the average. (Leaf check-in: 085f17e1 user: drh tags: stat1-max) | |
| 16:51 | • Edit [a4663f09c91d1381|a4663f09]: Edit check-in comment. (artifact: 13207166 user: drh) | |
| 15:44 | New checks in PRAGMA integrity_check to validate the autovacuum settings in the header. (check-in: a4663f09 user: drh tags: trunk) | |
| 13:39 | Enhanced detection of problems on the freelist and on overflow list in PRAGMA integrity_check. (check-in: 11e58f5b user: drh tags: trunk) | |

| 21:18 | Add the documentation text for the new VFS interfaces used by batch-atomic writes. (check-in: 5e944eea user: drh tags: batch-atomic-write) | |
| 21:01 | Transform two #ifdef statements into #if statements. (check-in: f2c6b584 user: drh tags: batch-atomic-write) | |
| 21:00 | Split SQLITE_ENABLE_ATOMIC_WRITE into two options - the original and SQLITE_ENABLE_BATCH_ATOMIC_WRITE. (check-in: 7eb9bf2c user: dan tags: batch-atomic-write) | |
| 20:51 | • Edit [416973ede3bde856|416973ed]: Move to branch batch-atomic-write. (artifact: 1ece4c5d user: drh) | |
| 20:49 | Fix a harmless typo, but one that would show up in the documentation if not fixed. (check-in: e4b1dd36 user: drh tags: trunk) | |
| 19:54 | • Edit [929bc46b8be0111a|929bc46b]: Mark "Closed". (artifact: a24c4001 user: drh) | |
| 19:49 | Add support for F2FS atomic writes. Untested at this point. (check-in: 416973ed user: dan tags: batch-atomic-write) | |
| 19:28 | Minor fix to the concurrent.test module so that it works on windows. (check-in: 58553d61 user: drh tags: begin-concurrent) | |
| 19:08 | Fix compiler warnings. (check-in: 44c760d1 user: drh tags: begin-concurrent) | |
| 18:56 | Fix a faulty #ifdef on the previous check-in (check-in: 7355e742 user: drh tags: begin-concurrent) | |
| 18:28 | Get the build working with SQLITE_OMIT_CONCURRENT. (check-in: a29401e9 user: drh tags: begin-concurrent) | |
| 17:47 | Merge all the latest trunk enhancements. (check-in: 213c61cb user: drh tags: begin-concurrent) | |
| 16:55 | Experimental API sqlite3_stmt_refresh() to force a prepared statement to recompile if it needs to due to a schema change or other factor. (Leaf check-in: 10556ee4 user: drh tags: sqlite3_stmt_refresh) | |
| 15:09 | • Edit [55791928f317a306|55791928]: Mark "Closed". (artifact: 2e953182 user: drh) | |
| 15:08 | Enhance the built-in date/time functions so that they can be used in CHECK constraints, in the WHERE clause or partial indexes, and index expressions, provided that none of the non-deterministic keywords ("now", "localtime", "utc") are used as arguments. (check-in: a90c062d user: drh tags: trunk) | |
| 14:36 | New test cases for date/time functions in indexes on expressions, in the WHERE clause of partial indexes, and in CHECK constraints. (Closed-Leaf check-in: b7f70c7f user: drh tags: index-on-date-func) | |
| 13:17 | Combine the Parse.ckBase and Parse.iSelfTab fields into just Parse.iSelfTab. This fixes a problem with date/time functions in check-constraints. Add some test cases for date/time functions in index expressions and check constraints. (check-in: 22eda098 user: drh tags: index-on-date-func) | |

| 18:59 | Fix a race condition in os_unix.c that may occur when one thread is opening a connection to a shared-memory block and another is either closing or locking the same shared-memory. (check-in: 3b7330c1 user: dan tags: trunk) | |
