| 18:09 | Remove the sqlite3PagerClearCache() routine, which does not accomplish anything useful. (check-in: f250166b user: drh tags: trunk) | |
| 15:53 | Performance optimization and size reduction on the freeP4() routine. (check-in: 4dc56e86 user: drh tags: trunk) | |
| 15:24 | Increase the version number to 3.14.0 since we are already making significant code changes. (check-in: 1a0d0576 user: drh tags: trunk) | |
