 3.0.5 -- October, 2019
 ----------------------
 
+- Fix OMPIO issue limiting file reads/writes to 2GB.  Thanks to
+  Richard Warren for reporting the issue.
+- At run time, automatically disable Linux cross-memory attach (CMA)
+  for vader BTL (shared memory) copies when running in user namespaces
+  (i.e., containers).  Many thanks to Adrian Reber for raising the
+  issue and providing the fix.
+- Sending very large MPI messages using the ofi MTL will fail with
+  some of the underlying Libfabric transports (e.g., PSM2 with
+  messages >=4GB, verbs with messages >=2GB).  Prior version of Open
+  MPI failed silently; this version of Open MPI invokes the
+  appropriate MPI error handler upon failure.  See
+  https://github.com/open-mpi/ompi/issues/7058 for more details.
+  Thanks to Emmanuel Thom� for raising the issue.
+- Fix case where 0-extent datatypes might be eliminated during
+  optimization.  Thanks to Github user @tjahns for raising the issue.
+- Ensure that the MPIR_Breakpoint symbol is not optimized out on
+  problematic platforms.
+- Fix OMPIO offset calculations with SEEK_END and SEEK_CUR in
+  MPI_FILE_GET_POSITION.  Thanks to Wei-keng Liao for raising the
+  issue.
+- Fix corner case for datatype extent computations.  Thanks to David
+  Dickenson for raising the issue.
+- Fix MPI buffered sends with the "cm" PML.
+- Update to PMIx v2.2.3.
+- Fix ssh-based tree-based spawning at scale.  Many thanks to Github
+  user @zrss for the report and diagnosis.
+- Fix the Open MPI RPM spec file to not abort when grep fails.  Thanks
+  to Daniel Letai for bringing this to our attention.
+- Handle new SLURM CLI options (SLURM 19 deprecated some options that
+  Open MPI was using).  Thanks to Jordan Hayes for the report and the
+  initial fix.
+- OMPI: fix division by zero with an empty file view.
+- Also handle shmat()/shmdt() memory patching with OS-bypass networks.
+- Add support for unwinding info to all files that are present in the
+  stack starting from MPI_Init, which is helpful with parallel
+  debuggers.  Thanks to James Clark for the report and initial fix.
+- Fixed inadvertant use of bitwise operators in the MPI C++ bindings
+  header files.  Thanks to Bert Wesarg for the report and the fix.
+- Added configure option --disable-wrappers-runpath (alongside the
+  already-existing --disable-wrappers-rpath option) to prevent Open
+  MPI's configure script from automatically adding runpath CLI options
+  to the wrapper compilers.
