Open MPI v5.0.0rc4 is now available for testing (https://www.open-mpi.org/software/ompi/v5.0/<https://www.open-mpi.org/software/ompi/v5.0/>).
Please test and send feedback either via the user mailing lists or create an issue at https://github.com/open-mpi/ompi/issues/<https://github.com/open-mpi/ompi/issues/>. This rc includes the addition of MPI Sessions support, the porting of MPI documentation and man pages to https://docs.open-mpi.org/, and various bug fixes. See https://docs.open-mpi.org/en/v5.0.x/news/news-v5.0.x.html for a change log. Known issues with rc4: * Not all man pages included in the tarball render correctly. Please use the new documentation website (https://docs.open-mpi.org/en/v5.0.x/man-openmpi/index.html) if you run into issues. * Builds configured with UCC ("configure --with-ucc ...") will fail with a compile error. There is a fix available at https://github.com/open-mpi/ompi/pull/10208 . * The "contrib/dist/linux/openmpi.spec" was not updated to reflect the documentation updates. RPM builds using this file will fail. Thank you, v5.0 Release Managers
