Eh, I'm not sure it is needed. Since my main site isn't 3.6 yet (tonight is the upgrade), I had my sphinx looking at my live data, and my vb install looking at a test db (with older data).
The dateline column on thread was added in 3.6, which is why I think it was broken. I'll know more tonight when we upgrade
Were you running into the dateline error on thread title?
