+3.1.2 -- August, 2018
+------------------------
+
+- A subtle race condition bug was discovered in the "vader" BTL
+  (shared memory communications) that, in rare instances, can cause
+  MPI processes to crash or incorrectly classify (or effectively drop)
+  an MPI message sent via shared memory.  If you are using the "ob1"
+  PML with "vader" for shared memory communication (note that vader is
+  the default for shared memory communication with ob1), you need to
+  upgrade to v3.1.2 or later to fix this issue.  You may also upgrade
+  to the following versions to fix this issue:
+  - Open MPI v2.1.5 (expected end of August, 2018) or later in the
+    v2.1.x series
+  - Open MPI v3.0.1 (released March, 2018) or later in the v3.0.x
+    series
+- Assorted Portals 4.0 bug fixes.
+- Fix for possible data corruption in MPI_BSEND.
+- Move shared memory file for vader btl into /dev/shm on Linux.
+- Fix for MPI_ISCATTER/MPI_ISCATTERV Fortran interfaces with MPI_IN_PLACE.
+- Upgrade PMIx to v2.1.3.
+- Numerous One-sided bug fixes.
+- Fix for race condition in uGNI BTL.
+- Improve handling of large number of interfaces with TCP BTL.
+- Numerous UCX bug fixes.

+3.1.1 -- June, 2018
+-------------------
+
+- Fix potential hang in UCX PML during MPI_FINALIZE
+- Update internal PMIx to v2.1.2rc2 to fix forward version compatibility.
+- Add new MCA parameter osc_sm_backing_store to allow users to specify
+  where in the filesystem the backing file for the shared memory
+  one-sided component should live.  Defaults to /dev/shm on Linux.
+- Fix potential hang on non-x86 platforms when using builds with
+  optimization flags turned off.
+- Disable osc/pt2pt when using MPI_THREAD_MULTIPLE due to numerous
+  race conditions in the component.
+- Fix dummy variable names for the mpi and mpi_f08 Fortran bindings to
+  match the MPI standard.  This may break applications which use
+  name-based parameters in Fortran which used our internal names
+  rather than those documented in the MPI standard.
+- Revamp Java detection to properly handle new Java versions which do
+  not provide a javah wrapper.
+- Fix RMA function signatures for use-mpi-f08 bindings to have the
+  asynchonous property on all buffers.
+- Improved configure logic for finding the UCX library.

+2.1.4 -- August, 2018
+---------------------
+
+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.
