The Open MPI Team, representing a consortium of research, academic, and 
industry partners, is pleased to announce the release of Open MPI version 
1.5.3.  This release adds a feature that was accidentally left out of v1.5.2.

*** Note that the "v1.5.x" series is the "feature development" series for Open 
MPI.  We consider it fairly stable, but it has not been as time-tested as the 
mature v1.4.x series.  Production sites may wish to stay with v1.4.x until the 
v1.5 series transitions to its "mature" counterpart (i.e., the v1.6 series). 

Version 1.5.3 can be downloaded from the main Open MPI web site or any of its 
mirrors (mirrors will be updating shortly). 

Here is a list of changes in v1.5.3 as compared to v1.5.2: 


- Add missing "affinity" MPI extension (i.e., the OMPI_Affinity_str()
  API) that was accidentally left out of the 1.5.2 release.
