e-Commerce 4.0 is now feature complete. Other than just doing the final clean ups and writting more of the standard extensions to modules like adding more filters to ec_charge, or some more product features. Since this is the case this is going to be the final BETA and if there are no major issues I will be releasing the first release candidate in the next week or so.
There has been a lot of work on getting the final piece of e-Commerce done. ec Charges is now implemented and working. It will create miscellaneous charges on any transaction. There is still work to be done on the extensions to ec charge but the API is quite nice and these will be added. If you have any ideas for filters, variables or calculations please drop just raise an issue, and I will look into it.
The main area I would like to be concentrated on is the ec charges. These are miscellaneous changes are added like setup fees, shipping, taxes, and anything else that can be dreamed up. Please post any issues and I will get them sorted as quick as possible.
