* Open MPI is now fully MPI-3.1 compliant
**********************************************************************
- Enhancements to reduce the memory footprint for jobs at scale.
A new MCA parameter - mpi_add_procs_cutoff is available to set
the threshold for using this feature.

- Enhancements to reduce the memory footprint for jobs at scale. A
new MCA parameter, "mpi_add_procs_cutoff", is available to set the
threshold for using this feature.
- Many enhancements to MPI RMA. Open MPI now maps MPI RMA operations
on to native RMA operations for those networks which support this
capability.
- ompi_info now shows all components, even if they do not have MCA
parameters. The prettyprint output now separates groups with a
dashed line.
- Add support for PMIx - Process Management Interface for Exascale.
Version 1.1.2 of PMIx is included internally in this release.
- Add support for PLFS file systems in Open MPI I/O.
- Add support for UCX transport.
- Improved support for MPI_THREAD_MULTIPLE.
- Update Java interfaces to MPI-3.1
- Simplify build process for Cray XC systems. Add support for
using native SLURM.
- Updated internal/embedded copies of third-part software:
- Update the internal copy of ROMIO to that which shipped in MPICH
3.1.4.
- Update internal copy of libevent to v2.0.22.
- Update internal copy of hwloc to v1.11.2.
- Removed checkpoint/restart code due to loss of maintainer. :-(
- Add a new MCA parameter - opal_common_verbs_want_fork_support. This
replaces the btl_openib_want_fork_support parameter.
- Add a -tune command line option to simplify setting many environment
variables and mca parameters.
- Removed --enable-mpi-profiling configure option.
- Add a --tune mpirun command line option to simplify setting many
environment variables and MCA parameters.
- Add a new MCA parameter -
"opal_common_verbs_want_fork_support". This replaces the
"btl_openib_want_fork_support" parameter.
- Add a new MCA parameter "orte_default_dash_host" to offer an analogue
to the existing "orte_default_hostfile" MCA parameter.
- Add --with-platform-patches-dir configure option.
- Add a new mca parameter default-dash-to-host to offer a mirror of
the default_hostfile.
- Add a --with-pmi-libdir configure option for environments that install
- Add --with-pmi-libdir configure option for environments that install
PMI libs in a non-default location.
- Add the ability to specify the number of desired slots in the --host
option.
- Remove support for OS X Leopard.
- Remove support for Cray XT systems.
- Remove VampirTrace.
- Remove support for Myrinet/MX.
- Remove legacy collective module:ML.
- Remove support for Alpha processors.
- Add the ability to specify the number of desired slots in the mpirun
--host option.
- In environments where mpirun cannot automatically determine the
number of slots available (e.g., when using a hostfile that does not
specify "slots", or when using --host without specifying a ":N"
suffix to hostnames), mpirun now requires the use of "-np N" to
specify how many MPI processes to launch.
- Removed some legacy support:
- Removed support for OS X Leopard.
- Removed support for Cray XT systems.
- Removed VampirTrace.
- Removed support for Myrinet/MX.
- Removed legacy collective module:ML.
- Removed support for Alpha processors.
- Removed --enable-mpi-profiling configure option.
- Removed checkpoint/restart code due to loss of maintainer. :-(
