| 16:28 | When estimating the number of rows visited by a range scan for which the keys consist of more than one field, consider prefixes of stat4 samples as well as the full samples. This generates more accurate estimates. (check-in: 3e0590dee0 user: dan tags: trunk) | |

| 21:02 | Always disallow functions as the DEFAULT of a column. Add assert()s and (Closed-Leaf check-in: a991bb1a9e user: drh tags: stat4-function) | |
| 19:12 | Disable multiplexing of master-journal files in the test_multiplex.c module. (check-in: b8684df395 user: dan tags: trunk) | |
| 18:38 | If an error occurs in the compile-time evaluation of an application-defined function, then propagate back out the exact error code, not just the generic SQLITE_ERROR. (check-in: 93f42586cc user: drh tags: stat4-function) | |
| 06:46 | The valueFromFunction() routine is better able to handle OOM errors. Omit unreachable branches. (check-in: 8fb6bd9be5 user: drh tags: stat4-function) | |
| 05:08 | Improve the text on one of the opcode documentation comments in vdbe.c. (check-in: 08958f5797 user: drh tags: trunk) | |

| 20:59 | Allow the default value for columns added using ALTER TABLE ADD COLUMN to be a function in existing schemas loaded from disk. But prevent this version of SQLite from being used to create such a column. (check-in: ff868e22ca user: dan tags: stat4-function) | |
| 20:06 | Allow the query planner to evaluate deterministic scalar SQL functions used in WHERE constraints if all arguments are SQL literals in order to compare the results with sqlite_stat4 sample data. (check-in: b7f1fc26d2 user: dan tags: stat4-function) | |

| 11:50 | Fix the bm25() function so that it multiplies scores by -1 before returning them. This means better matches have a lower numerical score, so "ORDER BY rank" (not "ORDER BY rank DESC") does what you want. (check-in: 3ee7b5a9f9 user: dan tags: fts5) | |
