| 20:24 | Allow vector IN(SELECT ...) expressions to use an index if either all the indexed columns are declared NOT NULL or if there is no difference between the expression evaluating to 0 and NULL (as in a WHERE clause). (check-in: e2fd6f49 user: dan tags: rowvalue) | |
| 19:34 | Add the json_quote() function to the JSON1 extension. (check-in: 269892ab user: drh tags: trunk) | |

| 00:43 | Fix sqlite3VdbeExpandSql() so that it handles OOMs by always returning NULL. (check-in: 5a027fe4 user: drh tags: sqlite3_trace_v2) | |

Fix the skip-scan code generator for WITHOUT ROWID tables so that it always checks the register and copies the result if it lands in the wrong register. Fix for ticket [8fd39115d8f46ece70e7d4b3]. (check-in: 793e206f user: drh tags: trunk) | |

| 22:59 | A new optimizer that breaks a lot of tests. But none of them critically, I think. Nevertheless, there is a lot of work ahead to stabilize the code. (CVS 2564) (check-in: 86ce56cc user: drh tags: trunk) | |
| 14:52 | Store the total number of rows as part of the ANALYZE statistics. (CVS 2563) (check-in: 868279c7 user: drh tags: trunk) | |
