Open MPI v2.1.4rc1 has been pushed. It is likely going to be the last in the
v2.1.x series (since v4.0.0 is now visible on the horizon). It is just a bunch
of bug fixes that have accumulated since v2.1.3; nothing huge. We'll encourage
users who are still using the v2.1.x series to upgrade to this release; it
should be a non-event for anyone who has already upgraded to the v3.0.x or
v3.1.x series.

If no serious-enough issues are found, we plan to release 2.1.4 this Friday,
August 10, 2018.
Please test!
Bug fixes/minor improvements:
- Disable the POWER 7/BE block in configure. Note that POWER 7/BE is
still not a supported platform, but it is no longer automatically
disabled. See
https://github.com/open-mpi/ompi/issues/4349#issuecomment-374970982
for more information.
- Fix bug with request-based one-sided MPI operations when using the
"rdma" component.
- Fix issue with large data structure in the TCP BTL causing problems
in some environments. Thanks to @lgarithm for reporting the issue.
- Minor Cygwin build fixes.
- Minor fixes for the openib BTL:
- Support for the QLogic RoCE HCA
- Support for the Boradcom Cumulus RoCE HCA
- Enable support for HDR link speeds
- Fix MPI_FINALIZED hang if invoked from an attribute destructor
during the MPI_COMM_SELF destruction in MPI_FINALIZE. Thanks to
@AndrewGaspar for reporting the issue.
- Java fixes:
- Modernize Java framework detection, especially on OS X/MacOS.
Thanks to Bryce Glover for reporting and submitting the fixes.
- Prefer "javac -h" to "javah" to support newer Java frameworks.
- Fortran fixes:
- Use conformant dummy parameter names for Fortran bindings. Thanks
to Themos Tsikas for reporting and submitting the fixes.
- Build the MPI_SIZEOF() interfaces in the "TKR"-style "mpi" module
whenever possible. Thanks to Themos Tsikas for reporting the
issue.
- Fix array of argv handling for the Fortran bindings of
MPI_COMM_SPAWN_MULTIPLE (and its associated man page).
- Make NAG Fortran compiler support more robust in configure.
- Disable the "pt2pt" one-sided MPI component when MPI_THREAD_MULTIPLE
is used. This component is simply not safe in MPI_THREAD_MULTIPLE
scenarios, and will not be fixed in the v2.1.x series.
- Make the "external" hwloc component fail gracefully if it is tries
to use an hwloc v2.x.y installation. hwloc v2.x.y will not be
supported in the Open MPI v2.1.x series.
- Fix "vader" shared memory support for messages larger than 2GB.
Thanks to Heiko Bauke for the bug report.
- Configure fixes for external PMI directory detection. Thanks to
Davide Vanzo for the report.
