UPGRADE PRICE. We have no special price for upgrades. Note that the manual (in post script) is on the download site as well as the server source code. If you wanted to have the new version on our CDROM and our nicely produced manual, it would cost the usual $40 (US) for the media. If you order a supported version of our software, we'll support you on that *server* even if you upgrade to the higher version of the product (either via download or media purchase).
