SCCM 1602 is now available, there are many new features, all of them can be found here https://technet.microsoft.com/library/mt622084.aspx#bkmk_1602
My two personal favorites are:
1. Support for in-place upgrade from Windows Server 2008 R2 to Windows Server 2012 R2 on SCCM server. You must uninstall WSUS before ugprade however.
2. Support for deploying Office 365 ProPlus updates. I already wrote here http://justforadmins.blogspot.com/2016/03/finally-deploy-office-365-updates-with.html
In few days time I will definately test the new release and report back other cool features!
