@unisuperbox is there anything stopping us from using OTA-16.x system? I understand the thought process behind the idea, however, if we are to switch to a system like this, maybe have it as OTA-x.16 to indicate which OTA it is and the LTS version after that? I feel that would allow easier distinction between the OTAs and not pose a potential issue with the current OTA system as it would work to make it think its a major version change, with the same minor version, just my $0.02
