well, you won't see 7.6 in 1 day, so sorry about that...
as i posted in the other thread, i'm still working on the upgrader...
in order to handle very large boards, the upgrader needs to import into a new database, since it needs to add proper indices to very large tables ( ubbt_POSTS, ubbt_TABLES ). to do an in place upgrade, would cause timeouts on queries and we don't want that.
the goal is the most painless / simple upgrader, that doesn't puke in the middle and leave your old board as dead. so it's very important to get it right.
