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

 # 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.

 # OVERALL: Added new ARMCI API implementation (experimental).

 # OVERALL: Added new MPIX_Group_comm_create function to allow
   non-collective creation of sub-communicators.

 # FORTRAN: Bug fixes in the MPI_DIST_GRAPH_ Fortran bindings.

 # 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.

 # PM/PMI: Bug fixes in memory allocation/management for environment
   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.

 # PM/PMI: Bug fixes for handling "=" in environment variable values in
   hydra.

 # PM/PMI: Upgrade the hwloc version to 1.2.

 # COLLECTIVES: Performance and memory usage improvements for MPI_Bcast
   in certain cases.

 # VALGRIND: Fix incorrect Valgrind client request usage when MPICH2 is
   built for memory debugging.

 # BUILD SYSTEM: "--enable-fast" and "--disable-error-checking" are once
   again valid simultaneous options to configure.

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

 # Several other minor bug fixes, memory leak fixes, and code cleanup.

===============================================================================
                               Changes in 1.3.2
===============================================================================

 # OVERALL: MPICH2 now recognizes the OSX mach_absolute_time as a
   native timer type.

 # OVERALL: Performance improvements to MPI_Comm_split on large
   systems.

 # OVERALL: Several improvements to error returns capabilities in the
   presence of faults.

 # PM/PMI: Several fixes and improvements to Hydra's process binding
   capability.

 # PM/PMI: Upgrade the hwloc version to 1.1.1.

 # PM/PMI: Allow users to sort node lists allocated by resource
   managers in Hydra.

 # PM/PMI: Improvements to signal handling. Now Hydra respects Ctrl-Z
   signals and passes on the signal to the application.

 # PM/PMI: Improvements to STDOUT/STDERR handling including improved
   support for rank prepending on output. Improvements to STDIN
   handling for applications being run in the background.

 # PM/PMI: Split the bootstrap servers into "launchers" and "resource
   managers", allowing the user to pick a different resource manager
   from the launcher. For example, the user can now pick the "SLURM"
   resource manager and "SSH" as the launcher.

 # PM/PMI: The MPD process manager is deprecated.

 # PM/PMI: The PLPA process binding library support is deprecated.

 # WINDOWS: Adding support for gfortran and 64-bit gcc libs.

 # Several other minor bug fixes, memory leak fixes, and code cleanup.
