I was going to release Pat 0.5.0 tonight, with full support for multiple table queries with From(tbl1, tbl2).select() syntax, but its getting late. I've gotten selection working fine. I need to centralize all query generation and keep things cleaner, and that also includes migration of the update query generation to the new From class, which will control all CRUD, now. Internally, single table operations will just create a From with themselves to handle the request. This should all be operation by tomorrow and I'll release then.
I may have broken my release-a-day spree with Pat, but at least I did make progress tonight, and that's the important part.
