> Subject: Open MPI v2.0.0rc3 now available
> We are now feature complete for v2.0.0 and would appreciate testing by 
> developers and end users before we finalize the v2.0.0 release.  In that 
> light, v2.0.0rc3 is now available:
> 
> https://www.open-mpi.org/software/ompi/v2.x/ 
> 
> Here are the changes since 2.0.0rc2:
> 
> - The MPI C++ bindings -- which were removed from the MPI standard in
>v3.0 -- are no longer built by default and will be removed in some
>future version of Open MPI.  Use the --enable-mpi-cxx-bindings
>configure option to build the deprecated/removed MPI C++ bindings.
> 
> --> NOTE: this is not new, actually -- but we just added it to the NEWS file.
> 
> - 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.
> 
> - Many updates and fixes to the revamped memory hooks infrastructure
> 
> - Various configure-related compatibility updates for newer versions
>of libibverbs and OFED.
> 
> - Properly detect Intel TrueScale and OmniPath devices in the ACTIVE
>   state.  Thanks to Durga Choudhury for reporting the issue.
> 
> - Fix MPI_IREDUCE_SCATTER_BLOCK for a one-process communicator. Thanks
>to Lisandro Dalcin for reporting.
> 
> - Fix detection and use of Solaris Studio 12.5 (beta) compilers.
>Thanks to Paul Hargrove for reporting and debugging.
> 
> - Allow NULL arrays when creating empty MPI datatypes.
> 
> - Miscellaneous minor bug fixes in the hcoll component.
> 
> - Miscellaneous minor bug fixes in the ugni component.
> 
> - Fix various small memory leaks.
> 
> - Notable new MCA parameters:
> 
>-  opal_progress_lp_call_ration: Control how often low-priority
>   callbacks are made during Open MPI's main progress loop.
> 
> - Disable backtrace support by default in the PSM/PSM2 libraries to 
>   prevent unintentional conflicting behavior.
