non-zero true_lb).
- Bunches of Windows build fixes.
- Now allow the graceful failover from MTLs to BTLs if no MTLs can
initialize successfully.
- Added "clobber" information to various atomic operations, fixing
erroneous behavior in some newer versions of the GNU compiler suite.

OpenFabrics .ini support file.
- Fix the use of hostfiles when a username is supplied.
- Various fixes for rankfile support.
- Updated the internal version of VampirTrace to 5.4.12.
- Fixed OS X TCP wireup issues having to do with IPv4/IPv6 confusion
(see https://svn.open-mpi.org/trac/ompi/changeset/22788 for more
details).
- Fixed some problems in processor affinity support, including when
there are "holes" in the processor namespace (e.g., offline
processors).
- Ensure that Open MPI's "session directory" (usually located in /tmp)
is cleaned up after process termination.
- Fixed some problems with the collective "hierarch" implementation
that could occur in some obscure conditions.
- Various MPI_REQUEST_NULL, API parameter checking, and attribute
error handling fixes.
- Fix case where MPI_GATHER erroneously used datatypes on non-root nodes.
- Patched ROMIO support for PVFS2 > v2.7 (patch taken from MPICH2
version of ROMIO).

mpi_paffinity_alone=1. Also fixed mpi_paffinity_alone=1 behavior
with non-MPI applications.
- Ensure that all OpenFabrics devices have compatible receive_queues
specifications before allowing them to communicate. See the lengthy
comment in https://svn.open-mpi.org/trac/ompi/changeset/22592 for details.
- Fix some issues with checkpoint/restart.
- Improve the pre-MPI_INIT/post-MPI_FINALIZE error messages.
- Ensure that loopback addresses are never advertised to peer
processes for RDMA/OpenFabrics support.
- Fixed a CSUM PML false positive.
- Various fixes for Catamount support.
- Minor update to wrapper compilers in how user-specific argv is
ordered on the final command line. Thanks to Jed Brown for the

broken VT documentation files.
- Fix a possible race condition in tearing down RDMA CM-based
connections.
- Relax error checking on MPI_GRAPH_CREATE. Thanks to David Singleton
