| 20:51 | As a special case, casting '-0.0' into numeric should yield 0. Fix for ticket [674385aeba91c774]. (check-in: 491f0f9bbd user: drh tags: trunk) | |
| 20:11 | Enhancements to the printf() logic in order to render a negative zero with a minus sign. (Leaf check-in: 6ba4be66be user: drh tags: negative-zero) | |
| 13:49 | Handle expressions like "expr IS TRUE COLLATE xyz" in the same way as "expr IS TRUE". Fix for [4d01eda8115b10d1]. (check-in: 5c6146b56a user: dan tags: trunk) | |
