| 21:23 | Fix an off-by-one error that cause a loop to (harmlessly) run more times than necessary. Performance optimization, not a bug fix. (check-in: 58f4e058f1 ... user: drh tags: trunk) | |

| 19:49 | Because version 3.52.0 was withdrawn, that means QRF has never been officially released. Hence the new nMultiInsert field of the spec can be moved out of the extensions area and into the main part of the spec, and the version number can drop back from 2 to 1. (check-in: cf19982241 ... user: drh tags: trunk) | |
