Currently Running Sage 300 Web API v1.0 | 6.4.0.20

I'm currently working on a integration project where I will be will utilizing the Sage 300 Web API. This integration will be focusing on Order Entry where we can insert a new order (POST) and eventually we will need to be able to update an existing order (PUT / PATCH). With the current version of the Sage Web API the only supported verbs are GET and POST for OEOrders. Sage 300 2019 is currently in beta testing and I was wondering if anyone would know or be able to check if the improvements to Sage 300 Web API include either either the PUT or PATCH verb for OEOrders. 

Thanks!
