I notice still no Windows binaries - does this version build correctly on Windows?
Cheers,
Edric.

Subject: [mpich2-announce] Announcing the availability of MPICH2 1.5rc2
A new release of MPICH2 (1.5rc2) is available from http://www.mcs.anl.gov/research/projects/mpich2/downloads/index.php?s=downloads
This is a feature-preview release. MPICH2 developers, testers and other advanced users are encouraged to try this release out and let us know if you encounter any problems. This release is not intended for production systems at this time; such systems should continue to use the latest release from the 1.4.x branch (currently 1.4.1p1).
The major additions in the 1.5rc2 release since 1.4.1p1 are highlighted below.
(Windows binaries are not available at this time)

The MPICH2 Team
===============================================================================
Changes in 1.5 ===============================================================================
# OVERALL: Nemesis now supports an "--enable-yield=..." configure
option for better performance/behavior when oversubscribing
processes to cores. Some form of this option is enabled by default
on Linux, Darwin, and systems that support sched_yield().
# OVERALL: Added support for Intel Many Integrated Core (MIC)
architecture: shared memory, TCP/IP, and SCIF based communication.
# OVERALL: Added support for IBM BG/Q architecture. Thanks to IBM
for the contribution.
# MPI-3: const support has been added to mpi.h, although it is
disabled by default. It can be enabled on a per-translation unit
basis with "#define MPICH2_CONST const".
# MPI-3: Added support for MPIX_Type_create_hindexed_block.
# MPI-3: The new MPI-3 nonblocking collective functions are now
available as "MPIX_" functions (e.g., "MPIX_Ibcast").
# MPI-3: The new MPI-3 neighborhood collective routines are now available as
"MPIX_" functions (e.g., "MPIX_Neighbor_allgather").
# MPI-3: The new MPI-3 MPI_Comm_split_type function is now available
as an "MPIX_" function.
# MPI-3: The new MPI-3 tools interface is now available as "MPIX_T_"
functions. This is a beta implementation right now with several
limitations, including no support for multithreading. Several
performance variables related to CH3's message matching are exposed
through this interface.
# MPI-3: The new MPI-3 matched probe functionality is supported via
the new routines MPIX_Mprobe, MPIX_Improbe, MPIX_Mrecv, and
MPIX_Imrecv.
# MPI-3: The new MPI-3 nonblocking communicator duplication routine,
MPIX_Comm_idup, is now supported. It will only work for
single-threaded programs at this time.
# MPI-3: MPIX_Comm_reenable_anysource support
# MPI-3: Native MPIX_Comm_create_group support (updated version of
the prior MPIX_Group_comm_create routine).
# MPI-3: MPI_Intercomm_create's internal communication no longer interferes
with point-to-point communication, even if point-to-point operations on the
parent communicator use the same tag or MPI_ANY_TAG.
# MPI-3: Eliminated the possibility of interference between
MPI_Intercomm_create and point-to-point messaging operations.
# Build system: Completely revamped build system to rely fully on
autotools. Parallel builds ("make -j8" and similar) are now supported.
# Build system: rename "./maint/updatefiles" --> "./autogen.sh" and
"configure.in" --> "configure.ac"
# JUMPSHOT: Improvements to Jumpshot to handle thousands of
timelines, including performance improvements to slog2 in such
cases.
# JUMPSHOT: Added navigation support to locate chosen drawable's ends
when viewport has been scrolled far from the drawable.
# PM/PMI: Added support for memory binding policies.
# PM/PMI: Various improvements to the process binding support in
Hydra. Several new pre-defined binding options are provided.
# PM/PMI: Upgraded to hwloc-1.5
# PM/PMI: Several improvements to PBS support to natively use the PBS
launcher.
# Several other minor bug fixes, memory leak fixes, and code cleanup.
