09:45 | Allow a user column name to be used on the LHS of a MATCH operator in FTS5. (check-in: 6f54ffd151 user: dan tags: trunk) | |
01:19 | Forward port the skip-ahead-distinct branch which was abandoned for some reason that I do not recall. This port should have been achived by a merge of trunk into the previous head of skip-ahead-distinct, but that did not work. So I had to manually "rebase" the changes.
