| 17:55 | Merge all recent trunk enhancements into the wal-shm-exceptions branch. (check-in: e59cea2d85 user: drh tags: wal-shm-exceptions) | |
| 17:14 | Fix octet_length() test cases so that they work when the database encoding is utf16. (check-in: ad2e39626e user: drh tags: trunk) | |
| 15:44 | Use the Kahan-Babushka-Neumaier algorithm to improve the accuracy of sum(). (check-in: c63e26e705 user: drh tags: trunk) | |
