Sasha - one of the things we discussed at the Sonoma conference was evolving our development process to emphasize the "Enterprise" in "Open Fabrics Enterprise Distribution". Part of that is minimizing disruption when new versions of OFED are installed. We want customers to feel comfortable upgrading to new versions of OFED, and that's not going to be true if they get surprised by other (previously working) software breaking after installation.
What John is asking for here (at least deliver both versions of the library for some period of time, and preferably don't break backward compatibility at all) seems pretty reasonable from the user's perspective, though I acknowledge that actually doing this requires extra effort. Separately, we should discuss how me manage version changes - introducing a version change in the middle of the RCs seems a bit late in the process.
