Valentine One Software Versions (not a debate about what detector is better)

Does anyone have knowledge about the various software versions for the Valentine One 1.8 hardware? I am considering sending my V1 1.8 in for a calibration and software update, but I wanted to read the software release notes. I tried contacting Valentine One via email, but they did not reply. I think this has been a topic of debate in the past which is why they are not responding. Anyway, Wikipedia has a list of all of the software versions, but not information about the differences. Any information would be helpful. Thanks in advance.
