Microsoft has recently released SCCM 1606 version which is Technical Preview, but all features will be included in next full release (1607), more here https://blogs.technet.microsoft.com/enterprisemobility/2016/06/20/update-1606-for-configuration-manager-technical-preview-available-now/
For me the most interesting feature is Cloud Proxy Role, I didn't find more particulare documentation about this feature, but it promises to be an easier way to manage SCCM clients on the Internet.
At this time there is internet-based client managemnt, but that is not trivial to configure this. Also if hybrid connection with Intune is used - it is not possible to install just Intune client un Internet computers and get info back to SCCM.
I will test this out and write more details about his feature later.
