This version covers one new query condition, with that you can use the Sql  "with clause" sub query replacement.  That feature gives you a powerful optimization feature, if you have many sub selects (SubSelect) within your sql query. In best case, these sub selects can be reduced to one, when using the "with clause" feature.

More information about using the withclause can be found here: http://blog.objectmapper.net/2007/12/07/using-the-sql-99-with-clause/

So, I wish you lot of fun with the new version.
Cheers
