[Huiwei Lu]

The MPICH team is pleased to announce the availability of a new preview
release (mpich-3.2b2).  This preview release adds several capabilities
including support for the proposed MPI-3.1 standard (contains nonblocking
collective I/O), full Fortran 2008 support (enabled by default), support
for the Mellanox MXM interface for InfiniBand, support for the Mellanox
HCOLL interface for collective communication, support for OFED InfiniBand
for Xeon and Xeon Phi architectures, significant improvements to the MPICH
Portals 4 implementation, and a completely revamped RMA infrastructure
providing scalability and performance improvements. This preview release
includes all the features planned for the 3.2.x release series.

    set to 3.0.

  # Fortran 2008 bindings are enabled by default and fully supported.

  # Added support for the Mellanox MXM InfiniBand interface.  (thanks
    to Mellanox for the code contribution).

  # Added support for the Mellanox HCOLL interface for collectives.
    (thanks to Mellanox for the code contribution).

  # Added support for OFED IB on Xeon and Xeon Phi.  (thanks to RIKEN
    and University of Tokyo for the contribution).

  # Significant stability improvements to the MPICH/portals4
    implementation.

  # Completely revamped RMA infrastructure including several
    scalability improvements, performance improvements, and bug fixes.

  # The Myrinet MX network module, which had a life cyle from 1.1 till
    3.1.2, has now been deprecated.

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