| 14:39 | Simplification to the error handling logic in the extension loader. (check-in: 07c77314 user: drh tags: trunk) | |
| 13:55 | Improve the error message that comes back when sqlite3_load_extension() fails because the named file exists but is not a valid shared library. (check-in: 05fee1a2 user: drh tags: trunk) | |
| 12:33 | Move the generation of output column names earlier in the case of a CREATE TABLE AS. This is a fix for ticket [3b4450072511e62] and a continuation of check-in [ade7ddf1998190b2b63] that fixes cases of ticket [de3403bf5ae5f72ed6] that were missed previously.
