- [feature] The Query.update() method is now
more lenient as to the table being updated. Plain Table objects are better supported now, and additional a joined-inheritance subclass may be used with update(); the subclass table will be the target of the update, and if the parent table is referenced in the WHERE clause, the compiler will call upon UPDATE..FROM syntax as allowed by the dialect to satisfy the WHERE clause. Target columns must still be in the target table i.e. does not support MySQL's multi-table update feature (even though this is in Core). PG's DELETE..USING is also not available in Core yet.
