===============================================================================

  # OVERALL: Improvements to fault tolerance for collective
    operations. Thanks to Rui Wang @ ICT for reporting several of these
    issues.

  # OVERALL: Improvements to the universe size detection. Thanks to
    Yauheni Zelenko for reporting this issue.

  # OVERALL: Bug fixes for Fortran attributes on some systems. Thanks
    to Nicolai Stange for reporting this issue.

  # PM/PMI: Support for a manual "none" launcher in Hydra to allow for
    higher-level tools to be built on top of Hydra. Thanks to Justin
    Wozniak for reporting this issue, for providing several patches for
    the fix, and testing it.

  # PM/PMI: Bug fixes in Hydra to handle non-uniform layouts of hosts
    better. Thanks to the MVAPICH group at OSU for reporting this issue
    and testing it.

  # PM/PMI: Bug fixes in Hydra to handle cases where only a subset of
    the available launchers or resource managers are compiled
    in. Thanks to Satish Balay @ Argonne for reporting this issue.

  # PM/PMI: Support for a different username to be provided for each
    host; this only works for launchers that support this (such as
    SSH).

  # PM/PMI: Bug fixes for using Hydra on AIX machines. Thanks to
    Kitrick Sheets @ NCSA for reporting this issue and providing the
    first draft of the patch.

    variables that was showing up on older platforms. Thanks to Steven
    Sutphen for reporting the issue and providing detailed analysis to
    track down the bug.

  # PM/PMI: Added support for providing a configuration file to pick
    the default options for Hydra. Thanks to Saurabh T. for reporting
    the issues with the current implementation and working with us to
    improve this option.

  # PM/PMI: Improvements to the error code returned by Hydra.

  # TEST SUITE: Several new tests for MPI RMA operations.
