SAP CRM integration with C4C via HCI

Hi All,

We are integrating SAP CRM on premise with C4C via HCI. I would like to know the difference between SP 0 and latest release of CRMPCD01 Addon which required for the integration between SAP CRM and SAP C4C via HCI. I am aware latest version will make integration with HCI much easier and comes up with additional functionality such as an important feature of automatic configuration of code list mapping which can potentially avoid lot of manual work.

It would be great if any one provide us links or difference between SP 0 and other versions of this Addon CRMPCD01.

Thanks,

Rajesh N
