Does installing a new version require a complete rebuild of my site as far as any modifications I have made to the original package or is there a way to modify only a few files to upgrade? I want to install and test your cart but I see that version 5 is due out soon and I don't want to install a 4.x version and have to reinstall everything a short time later when version 5 comes out. Do you have an estimate when 5 will be released
Gracias
