SaaS Versioning and "Lingo"
Our Test environment had been updated to 3100.11.0 which is equal to Q4 2016 CU1
The Test environment is on CD or "Continuous Delivery".

When it came time to upgrade our production environment which is on Flexible Deployment Option known as FDO the version was listed as 3100.0.2.

That took me by surprise and I immediately re-did all of my tool testing.  In searching Behind the Blackboard, I discovered an article 000043586 which indicated my version was Q4, 2016 CU1 with 2 security patches.  

I reached out to a few Blackboard sources and learned about how that in the version numbers:
- the first 4 numbers represent the "release" 3100 = Q4 2016
- first set of number after the first decimal (3100.11.0) represents the build for CD, continuous delivery build #11
- the second set of numbers after the second decimal (3100.0.02) represents the build for the FDO, flexible deployment .0.2
