The Open MPI Team, representing a consortium of research, academic, and industry partners, is pleased to the next release in the stable release series: Open MPI version 1.6.5.

Version 1.6.5 is a minor bugfix release. All users are encouraged to upgrade to v1.6.5 when possible.

Note that v1.6.5 is ABI compatible with the entire v1.5.x and v1.6.x series, but is not ABI compatible with the v1.4.x series. See for a description of Open MPI's release methodology.

Version 1.6.5 can be downloaded from the main Open MPI web site or any of its mirrors (Windows binaries may be available eventually; Open MPI needs a new Windows maintainer -- let us know on the developers' list if you're interested in helping out).
