Release Notes: This release is comprised of a rollup of incremental bugfixes and compiler updates since version 7.1.1. The most noticable change will be the updates to support modern versions of common compilers by updating configure tests and upgrading to the latest version of GNU Libtool.

Release Notes: A variety of new modules were added, including Infiniband point-to-point, shared memory collectives, and SLURM. Upgraded or fixed modules include Myrinet (1.6, 2.0.x), BProc (v4.0), and MagPIe collectives. New MPI-2 collectives (intercommunicators, EXSCAN, and ALLTOALLW) and MPI-2 datatypes (MPI_INTEGER[1|2|4|8] and MPI_REAL[4|8|16]) were added. "mpi_hostmap" functionality was added for users with multiple TCP networks. SSI modules can now be loaded dynamically at run-time instead of compiled into the MPI library.

Release Notes: An obscure race condition that occurred when running over 255 nodes was fixed along with a rare upper/lower bound datatype calculation error. MPI_IGNORE_ERRORCODES was changed to have correct casting, and TCP socket buffer run-time sizing was corrected. The interface detection code was reworked to allow arbitrary numbers of network interfaces, and fixes were made for TM (PBS), Solaris, and Sun Grid Engine. Some documentation and help messages were corrected.
