Thanks for your responds to my previous article. There are some people who have applied to become beta testers. This process will shortly begin. There have been found some bugs in the shipping module which still need fixing. Payment integration will be completely redone in v 1.2. So I can't promise that mambo-phpShop version 1.2 will be out when Mambo 4.5.1 stable is released! Please be patient, because the new mambo-phpShop will be more stable and reliable than any version before.
