Zoho CRM

With the release of CS-Cart 4.0.1 and the API, what's the timetable to get integration with Zoho CRM? I am asking specifically about Zoho CRM because this is one of the free CRMs for small businesses, unlike other (low-cost) solutions like Brightpearl.

Are there any other free CRMs out there that work with CS Cart 4?

Thanks for any suggestions,
