Understand SCCM Versions.
I believe Microsoft has not release any SCCM version in the name pattern as the old patterns SCCM 2007, SCCM 2012. It stopped the naming on SCCM 2012 R2, after that it started adding Build Numbers based on the years of release.
SCCM 2012 R2 release in 2015 is call SCCM 1511
SCCM 2012 R2 release in 2016 is call SCCM 1606
They are based on Year and Month of build.

What are they for ?
Any clarifications on this topic will be very much appreciated.
