Latest version of SBM

Hello,

We use TeamTrack/SBM as our ticketing system.  I have been asked to see if there is a newer version. 

We are currently on - 

Version:
Solutions Business Manager 12.02.00.00.6422 (Build 2745)

I have called the Support line and was told the newest version was 11....  Clearly not the case.  They could not find a way to figure out the latest version so here I am. 

Can someone who knows, please provide me an answer?
