SCCM License Question

Hi everyone,

I've not long started at my current job and so I've been looking at what licenses the company holds for SCCM.  The actual license says "System Center 1606 Configuration Manager Client Management Licence".  My question is, does this mean that I cannot install the latest updates, eg 1706?  The answer might be obvious but I'd just like some clarification :-)

Thanks,

Wayne
