+- 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.
-- 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.
+- 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.
+- 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. :-(
