            prefetch

          default value insert is requested (RT#28875)
        - Make IC::DT extra warning state the column name too
        - It is now possible to transparrently search() on columns

        - Calling the accessor of a belongs_to when the foreign_key
          was NULL and the row was not stored would unexpectedly fail
        - Split sql statements for deploy only if SQLT::Producer returned a scalar
          containing all statements to be executed
        - Add as_query() for ResultSet and ResultSetColumn. This makes subqueries
          possible. See the Cookbook for details.

        - Allow a scalarref to be supplied to the 'from' resultset attribute
        - Classes submitted as result_class for a resultsource are now
          automatically loaded via ensure_loaded()
        - 'result_class' resultset attribute, identical to result_class()
        - add 'undef_on_null_fk' option for relationship accessors of type 'single'.
          This will prevent DBIC from querying the database if one or more of
          the key columns IS NULL
        - for 'belongs_to' rels, 'undef_on_null_fk' defaults to true.
        - fixed scope unaware last_insert_id fetching for MSSQL
          (http://msdn.microsoft.com/en-us/library/ms190315.aspx)

        - insert should use store_column, not set_column to avoid marking
          clean just-stored values as dirty. New test for this
        - regression test for source_name

          hash construction algorithm
        - Allow explicit specification of ON DELETE/ON UPDATE constraints

        - Add ResultSet::_is_deterministic_value, make new_result filter the
          values passed to new to drop values that would generate invalid SQL.
        - Use Sub::Name to name closures before installing them. Fixes
          incompatibility with Moose method modifiers on generated methods.

          foreign and self parts the wrong way round in the condition

        - Added sqlt_deploy_hook to result classes so that indexes can be
          added.
        - Added startup checks to warn loudly if we appear to be running on
          RedHat systems from perl-5.8.8-10 and up that have the bless/overload
          patch applied (badly) which causes 2x -> 100x performance penalty.
