Site Servicing Status is a BIG news on the 1511 version and will be the place where you will find new versions of Configmgr. Easy to upgrade. So it keeps the release pace with Intune and Windows 10. This is very very good.
Support for the new Classification - Upgrades. This delivers new Windows 10 builds.
But be carefull with this as it may cause massive download on your Distribution Points.

With SCCM 2012 there was a big change in how deployments were presented.
Deployments to Computers were shown in the Software Center client, and Available User Deployments were shown in the Application Portal. Great Self Service Portal, that you can publish all your software applications for the users to pick up and install when they want.
Now with this you Software Center Client, users will be able you see both the Computer and User based Deployments in the Software Center view.
And yes Building and Capturing a Windows 10 Image works, with Updates!! :-)
