  [DELTA]

3.30    2013-11-12
        - Fix missing parent prereq in META.{yml,json} and NotBuild.PL
          (Dagfinn Ilmari Mannsåker, #89650)
        - Respect PERL5LIB in tainting source handler test (Dagfinn Ilmari Mannsåker,
          Leon Timmermans)
        - Use base instead of parent:

          This dist is used for testing all other modules, so it should avoid
          having any non-core prerequisites.  Having parent as a prereq leads to a
          circular dependency of parent -> Test::More -> Test::Harness. (Graham Knop)
        - Various POD fixes (Nathan Gary Glenn)
        - Don't localize all of %ENV in harness.t (Craig Berry)
        - Give TAP::Harness::Beyond a unique NAME (Leon Timmermans)
