REVISION SUMMARY
  https://phab.mercurial-scm.org/rHGc8e2d6ed1f9ea4eee7b28250b5aff22433d538b6 moved some objects used by Evolve and hence broke the latest
  Evolve revision. Next Evolve version will use the new objects when available
  but introduce deprecated aliases so users using older version of Evolve won't
  have a broken Evolve extension.
