                               Changes in 3.0
===============================================================================

 # MPI-3: All MPI-3 features are now implemented and the MPI_VERSION
   bumped up to 3.0.

 # OVERALL: Added support for ARM-v7 native atomics

 # MPE: MPE is now separated out of MPICH and can be downloaded/used
   as a separate package.

 # PM/PMI: Upgraded to hwloc-1.6

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

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

 # 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.
