Hi,
First i want to thank everyone for zen cart and all the support, it's really a great piece of software :)

I sell downloadable products (audio sample libraries) on my website here: www.acousticsamples.net

And sometimes i release updates of those libraries so i add some attributes and download links to a product. The problem is that the download links in the orders do not change.

So basically i would need a way to deliver updates to existing customers of a certain product. I thought about adding links in the orders accounts only if the customer purchased the product, but as i release updates quite often, that could get hard to maintain.
I also saw the solution of editing the orders with an addon, but i don't want to do this by hand.

Any suggestion?
