          later versions.  (I use the term better loosely.)
        - The SQL::T parser class now respects a relationship attribute of

        - added DBIx::Class::Schema::load_namespaces, alternative to

          Class::Accessor::Grouped. Only user noticible change is to
          table_class on ResultSourceProxy::Table (i.e. table objects in
          schemas) and, resultset_class and result_class in ResultSource.
          These accessors no longer automatically require the classes when
          set.

          provided
