- MPI_Connect/accept between applications started by different mpirun
commands will fail, even if ompi-server is running.

2.1.5 -- 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 v2.1.5 to fix this issue. You may also upgrade to the
following versions to fix this issue:
- Open MPI v3.0.1 (released March, 2018) or later in the v3.0.x
series
- Open MPI v3.1.2 (expected end of August, 2018) or later
- A link issue was fixed when the UCX library was not located in the
linker-default search paths.

2.1.4 -- August, 2018
