| 16:06 | Fix a fairly obscure problem allowing an "ALTER TABLE RENAME col TO ..." statement to modify the schema in such a way as to break a reference within a trigger program. (check-in: 64bec9e621 user: dan tags: trunk) | |
| 14:53 | Use the full 64-bit integer value in the argument to randomblob(). (check-in: 05df5f7aea user: drh tags: trunk) | |
