===============================================================================
                               Changes in 3.0.4
===============================================================================

 # BUILD SYSTEM: Reordered the default compiler search to prefer Intel
   and PG compilers over GNU compilers because of the performance
   difference.

   WARNING: If you do not explicitly specify the compiler you want
   through CC and friends, this might break ABI for you relative to
   the previous 3.0.x release.

 # OVERALL: Added support to manage per-communicator eager-rendezvous
   thresholds.

 # PM/PMI: Performance improvements to the Hydra process manager on
   large-scale systems by allowing for key/value caching.

 # Several other minor bug fixes, memory leak fixes, and code cleanup.
