Ubuntu 7.04 (Feisty) CDs Shipped Early?

I requested three CDs April 11th and when I checked up on my order a couple of days later it had said that they had been approved and sent to the shipping company on April 14th(5 days before release?). I was wondering if there had been a mistake or if they had just approved my request and were waiting for release to ship them. It's not a big problem but I thought I should ask anyway, since if it was shipped early it must've been Beta or something because there weren't even any images on the servers yet(Except beta). That wouldn't be a bad thing necessarily because I could update it after installing but I'd like to avoid that if possible. ^.^

So thanks for reading and I hope you guys have a nice day. :)
