Hi Fellow Namites, I've tagged the master head before persistence changes as Rosetta. That's what you should prefer to check out to read ancient Nama projects, to store them in a modern format, or to batch convert old projects. With that remaining as a bridge, I think this might be a good time to begin to remove backwards compatibility baggage from what will be the new the mainline persistence code. The new persistence changes I'll first pilot in a development branch. Ideally, I'd like some testing before I merge them into master. Regards, -- Joel Roth
