The MPICH2 Team

                                 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

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

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

   # 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.

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

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