Actually, I don't keep copies of old versions unless they're a useful version. In this case, I didn't keep any. I'm actually going to try and experiment and see if I can get more boards for less money from SEEED. I'm putting three copies on one panel and if I get ten panels, I'll get 30 boards when I cut them apart. The only slight oddity is when I duplicate the design, I get different component ID's, but that's not really that significant. Here's an example of what I mean. I'll simply cut along the white lines to make three boards.
