As Ralph says, the intent has been to maintain binary compatibility across minor releases. As for testing, I have not done extensive testing for binary compatibility, but I have tested 1.3 & 1.3.2-built versions of IMB and the NPB suite with 1.3.3 and did not have any problems. I did this for sm, tcp & openib transports. So, in my environment, binary compatibility looks to have been maintained within the 1.3-series releases. Please let us know if you run across any binary incompatibilities.
