The myReef software does not come on the units themselves. It is downloaded from the DA site and installed on a computer. Where did you buy the system? If you bought it directly from DA, then it would have been shipped with the most up to date firmware. If it came from a retailer, then it all depends on how long they have had that particular one in stock. It has been several months since the last firmware update so if the retailer got it in recently then you would be fine. I wouldn't worry too much about it unless you hook it up and have issues out of the box.
