In other words, if I want to install 2.0.0a2 and use ZODB3, I have no alternative but to start from scratch...?

That sucks.

I hate to ask this, but isn't this pretty significant? I assume you're giving priority to this issue, and that we can expect a fix any day now, right? :-)

Yes, it is significant, but this is an _alpha_ release - alphas are generally (almost always) not feature complete. If this is a necessity for you, you should probably wait for the beta cycle to begin... Brian Lloyd brian@digicool.com Software Engineer 540.371.6909 Digital Creations http://www.digicool.com
