14:07 | Avoid transfering records between tables unless the default values for all columns are the same. Fix for [f67b41381a]. (check-in: f8c4c495e6 user: dan tags: trunk) | |

14:42 | Make sure ORDER BY clauses on joins that involve virtual tables and that have a DISTINCT clause work correctly. This is a candidate fix for ticket [388d01d4bb8f9]. Test cases for that ticket will be checked in separately. (check-in: 1711381226 user: drh tags: trunk) | |
