There have been enough minor fixes to warrant a 4.1.6 release. We've posted 4.1.6rc1 tarballs in the usual location: https://www.open-mpi.org/software/ompi/v4.1/
Changes since v4.1.5: * Update to properly handle PMIx v>=4.2.3. Thanks to Bruno Chareyre, Github user @sukanka, and Christof Koehler for raising the compatibility issues and helping test the fixes. * Fix minor issues and add some minor performance optimizations with OFI support. * Support the "striping_factor" and "striping_unit" MPI_Info names recomended by the MPI standard for parallel IO. * Fixed some minor issues with UCX support. * Minor optimization for 0-byte MPI_Alltoallw (i.e., make it a no-op). We would welcome and testing and feedback. Thanks, Brian & Jeff
