I’m a Zen Cart guy, so normally the only thing I have to say about osCommerce is, “Them’s fighting words!”
But Gary Burton is a true open source hero, who has provided an upgrade path for merchants whose businesses depend on an active branch of osCommerce that works with modern versions of PHP. Thank you, Gary, for your leadership in creating the Frozen and Edge branches of osCommerce.
