===============================================================================
                               Changes in 3.0.3
===============================================================================

 # RMA: Added a new mechanism for piggybacking RMA synchronization operations,
   which improves the performance of several synchronization operations,
   including Flush.

 # RMA: Added an optimization to utilize the MPI_MODE_NOCHECK assertion in
   passive target RMA to improve performance by eliminating a lock request
   message.

 # RMA: Added a default implementation of shared memory windows to CH3.  This
   adds support for this MPI 3.0 feature to the ch3:sock device.

 # RMA: Fix a bug that resulted in an error when RMA operation request handles
   where completed outside of a synchronization epoch.

 # PM/PMI: Upgraded to hwloc-1.6.2rc1.  This version uses libpciaccess
   instead of libpci, to workaround the GPL license used by libpci.

 # PM/PMI: Added support for the Cobalt process manager.

 # BUILD SYSTEM: allow MPI_LONG_DOUBLE_SUPPORT to be disabled with a configure
   option.

 # FORTRAN: fix MPI_WEIGHTS_EMPTY in the Fortran bindings

 # MISC: fix a bug in MPI_Get_elements where it could return incorrect values

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